A hex nut with nylon inserts is built to be used having high temperature applications

Individual Chamfer Nut

A single chamfer nut is a type of fastener that features a flat surface in one side which resembles a washer dryer. This flat surface is required to help send the load of any tightened bolt as well as nut more evenly to the surface of the material that it is clamping jointly. This helps reduce damage or deformation on the material being fastened which enable it to also increase the strength from the joint. Single chamfer nuts are available in a variety of heights or thicknesses, that will be made by metal or cheap. They can end up being machined in a considerable number of thread types in addition to strengths, as well several different finishes.

Hex flange nuts have an made bigger base that flares out from the bottom of the nut. Custom Hex Nuts Manufacturers This enables the actual nut to span an oversized hole and provide a more perhaps bearing stress or clamping force over a standard hex fanatic. The flanged design belonging to the nut also resists loosening via vibration.

Nuts are generally threaded on both sides so that you can be screwed into place and turned clockwise in order to apply a torque that could tighten or clamp the actual materials being fixed together. Most nuts are threaded from a standard hexagon structure, but some classic hex nuts include additional features that can make them more suited to specific applications.

Lock nuts are a type of nut that, when employed in pairs, can provide some prevailing torque to hold the nuts by backing off as well as loosening. They are thinner than the usual normal hex nut so are often used inside situations where a minimal profile nut becomes necessary. They are also known as jam nuts and come in both low carbon dioxide steel and mark 5 medium carbon dioxide steel or stainless steel.

Rod coupling nuts use a free spinning outside tooth lock washer that acts in order to restrict the movement of a fastener and is usually installed without equipment. They are very popularly used in applications including pole lines where by long bolts must be threaded into wood poles and crossarms.

Semi-cone point crazy have an end that is just like a chamfered issue but has more material peeled off the surface on the nut. This feature permits the nut to be able to penetrate wood as well as fiberglass poles with less effort, enabling them being installed quickly and efficiently.

A hex nut with nylon inserts is built to be used having high temperature applications and is known for a locking action of which works by including the nut that has a collar of nylon filled nylon that can form a frictional fit contrary to the back end on the threaded fastener, forbidding the screw by loosening during vibration. The nylon fit is re-usable following nut is taken away, as it will return to its original condition and allow the actual screw or bolt to suffer again.

Hex nuts presented in several thicknesses and also heights, referred to as series/types. A number of the most popular comprise NE (Light Hex, Normal Height), NTE (Heavy Hex, Thin (Jam) Height), as well as NM (Machine Screw Pattern, Full Height). They comes in either a ordinary finish or hot-dip galvanized and consist of low carbon metal, Grade 5 moderate carbon steel, or even 18. 8 s / s.

Triple Eccentric Butterfly Valve Manufacturer in India

Specialityvalve is famous for its Triple Eccentric Butterfly Valve Manufacturer in India. A Butterfly Valve is a mechanism that regulated the flow of materials within a large pipe diameter by the quarter-turn of the disc. It is a motion like a butterfly that has wings that move up and down at 90 degrees. The butterfly valve is a metal disc framed on a rod. It is operated when the valve completely blocks the passageway and when it is open, the disc is rotated a quarter turn so that it allows an almost unrestricted passage of the fluid. The valve may also be opened gradually to compress the flow.

Triple eccentric butterfly valve are industrial valves that are designed to fully open or close a passage of the working medium flowing through a pipeline. They can also use for flow control purposes. They are bubble-tight shut off which cannot be accomplished by utilizing twofold counterbalanced butterfly valves.

The valve has 3 balances in contrast with the concentric butterfly valve. This triple counterbalance has one extra counterbalance which is a funnel-shaped seat. The tapered shape seat will match the plate that was created to match the seat. This plan will make the seat has no grating or rubbing while shutting or opening. This design will additionally make the triple eccentric butterfly valve from an air pocket, tight in high-weight applications.

Titanium rods can meet the requirements of lightweight building materials. Titanium has a low density, about 60% of steel, 50% of copper, and 1.7 times that of aluminum, but it has almost the same strength as ordinary steel. As a building, it can reduce weight by 70% to 75%. It is easy to hoist and can make buildings. The center of gravity of the object is moved down to improve the overall earthquake resistance of the building. Titanium rod has good corrosion resistance: it can resist urban pollution, industrial radiation and extreme erosion. Titanium rod is easy to process into thin plates and has good welding performance. Titanium itself has a shiny silver-white luster, and through treatment, a brighter surface can be obtained. In order to achieve a more beautiful decorative effect, different patterns and colors can be obtained by etching and anodizing. 

Titanium alloy rods have good features such as high specific strength, good high-temperature mechanical properties and excellent corrosion resistance, thus have been applied in aerospace, transportation, power generation and chemical industries. Titanium alloys are particularly good for THA components because of their high corrosion resistance compared with stainless steel and Co–Cr–Mo alloys. 

Titanium foil material is mainly used for loudspeaker and speaker treble film, with titanium foil to do high fidelity, clear and bright sound. Titanium foil materials can also be used for precision accessories, for bone implants and so on.

Flanges are common elements used to connect components within a piping system. Titanium piping and any other piping require a way of connecting the different components that form part of a pipeline, such as the pipes themselves, valves, pumps, filters, among other equipment. Flanges are normally defined as a protruding ridge or rim which is intended to increase the strength of an element or distribute the load applied on it. When used to connect elements in a piping system, a titanium flange is usually a protruding rim that is welded and/or bolted to the elements requiring the connection.

Titanium casting is a manufacturing process that uses titanium. It replicates the exact shape of an item. Melted titanium poured into a wax pattern mold. Specialized ceramic material is then coated into the wax pattern mold and left to dry and harden. The wax pattern mold is then inverted and heated to let the wax melt and drip out of it. The ceramic shell becomes a superfluous investment mold. Liquefied titanium is then poured into the mold and cooled off. The mold is then broken off to reveal the replicated item.

The titanium pipe is produced through an automated continuous production line, using titanium strips with uniform wall thickness through cold bending forming, welding, online heat treatment, sizing and straightening, non-destructive testing and air tightness testing. From sponge titanium to welded pipes, the material utilization rate is usually around 80%.  If the titanium coil is used as the raw material, the material utilization rate is above 95%. 

A titanium washer is a thin plate (typically disk-shaped, but sometimes square) with a hole (typically in the middle) that is normally used to distribute the load of a threaded fastener, such as a bolt or nut. Other uses are as a spacer, spring (Belleville washer, wave washer), wear pad, preload indicating device, locking device, and to reduce vibration (rubber washer). High-quality bolted joints require hardened steel washers to prevent the loss of pre-load due to brinelling after the torque is applied. Washers are also important for preventing galvanic corrosion, particularly by insulating steel screws from aluminium surfaces. They may also be used in rotating applications, as a bearing. 

A titanium screw and bolt are similar types of fastener typically made of metal and characterized by a helical ridge, called a male thread (external thread). Screws and bolts are used to fasten materials by the engagement of the screw thread with a similar female thread (internal thread) in a matching part. Screws are often self-threading (also known as self-tapping) where the thread cuts into the material when the screw is turned, creating an internal thread that helps pull fastened materials together and prevents pull-out.

Of all metals in their purest form, tungsten has the highest melting point (3422°C). This can be hugely beneficial in certain situations (particularly when compared to other more common metals). For example, it makes tungsten an excellent material for high-temperature environments – and this is why it is so widely used in the aerospace, automatic and construction industries. Tungsten metal is also regularly used to create alloys and superalloys. Its extremely high melting point and resistance to thermal creep help to strengthen the alloy, making it suitable for more thermally intensive applications, where other metals would fail.

The molybdenum filament is silvery white, very hard transition metal, but is softer and more ductile than tungsten. Molybdenum is a valuable alloying agent, as it contributes to the hardenability and toughness of quenched and tempered steels. It also improves the strength of steel at high temperatures. Molybdenum is used in alloys, electrodes and catalysts. Molybdenum filament is used in certain nickel-based alloys, such as the "Hastelloys(R)" which are heat-resistant and corrosion-resistant to chemical solutions. Molybdenum filament oxidizes at elevated temperatures. The metal has found recent applications as electrodes for electrically heated glass furnaces and foreheaths. The metal is also used in nuclear energy applications and for missile and aircraft parts.

Maintenance-Free Rod End

The maintenance-free rod end is also known as a self-lubricating, spherical bearing. It consists of a steel housing with an integral shank and a spherical PTFE FRP sliding contact surface. The housing is zinc-coated to prevent corrosion. Stainless steel and FRP  Maintenance free rod end materials are used in maintenance-free rod ends. When evaluating the maintenance-free rod end, keep in mind that the threaded shank and spherical plain bearing are essential components of the unit.

A maintenance-free rod end is a threaded male rod end with a threaded shank and a spherical plain bearing. It is also a non-sealed, self-lubricating rodend. Stainless steel and Nylon are both common materials for these rod ends. In addition, the rod ends can also be manufactured with other materials.

What Kind of Earth Rod Should You Use For Your System?

Earth rods or earth electrodes are conducting elements that enable an electrical system to channel the faulty flow of electricity of the ground without causing harm to an operator or the electrical system. These are metallic rods buried underneath the ground level so that the excess current flowing does not harm anyone on the way and are resistant to corrosion. They also provide low electrical resistance with the earth to allow for the dissipation of currents.

Electrodes or earth rods are also used in buildings and other constructions to channelize lightning strikes directly to the ground saving the electrical system, equipment, and electronics connected. The Earth Rod Price depends on the type of rods, the metal used to manufacture, purpose, and capacity. Worldwide, Copper Bonded Earth Rods which comply with IEC 62561 Part 2 are some of the most popular Earth Electrodes.

Types of earth rods to choose

There are different kinds of earth rods designed and manufactured based on the needs in commercial and domestic spheres, and are available in a variety of sizes.

Let us check the types of earth rods for you to consider the ideal model suitable for your specific requirement.

·         Copper bonded earth rods

There are two types of such rods - external threaded and the other is unthreaded and pointed. In both the types, each rod is made by molecularly bonding 99.9 % pure electrolytic copper.

Copper bonded earth rods are one of the most cost-effective solutions for domestic and commercial purposes. Because of less copper Earth Rod Price, it is conveniently used for small electrical systems of industries and even for residential premises. This design has a steel core with copper bonds that enhances its conduction rate to a considerable extent.

·         Pure copper earth rods

These earth rods, internal or external threaded are entirely made of copper to provide minimum resistance and are used in industries where corrosion can be a big factor.

Copper generally resists corrosion and offers excellent earth conductance for a long period. Due to their longer lifespan, these copper earth rods are used for industrial purposes.

·         Stainless steel earth rods

These earth rods, made from the highest-quality corrosion-resistant stainless steel, are used for different electrical systems. These rods are manufactured from austenitic stainless steel to BS970, grade 316. These earth rods are also used to overcome condition of galvanic corrosion which may be caused due to dissimilar metals being buried nearby.

·         Galvanized steel earth rods

These rods cost the lowest, are made up of high strength low carbon steel and hot dipped galvanized. This design of the rod is a cost-effective option for earthing used in electrical systems.

Final words

Considering all these types of earth rods, the Earth Rod Price, and the reasons for using them, you can choose a suitable one and install it with an electrical system. Also, make sure that they are rigorously tested on mechanical, electrical and chemical aspects as per international standards to ensure compliance and the highest level of quality & production.

Redrawing boundaries: Fieldwork in the context of Ōtautahi

Exhibition companion essay commissioned by Toi Moroki CoCA from Bojana Rimbovska on the occasion of Peter Robinson’s Fieldwork, 3 March - 27 May 2018. Full exhibition photos can be viewed at fieldwork.website; photos in this essay by Daniela Aebli, courtesy of CoCA & Peter Robinson

Scattered across, between, and outside of CoCA’s gallery spaces are Peter Robinson’s delicate wire forms. Each holds their space within the demanding environment of CoCA’s brutalist building which has played host to a variety of exhibitions throughout its fifty-year history, and is again activated through Robinson’s playful spatial interventions. Evident in the exhibition are some common threads which have carried throughout his recent practice, namely his interest in the ways in which spatial arrangements are used to create new lines of sight and lead to a more conscious interaction with the gallery space. Fieldwork also invites the audience to engage in a conversation around the language of sculpture, and presents Robinson’s ongoing exploration of artistic convention and our consumption of it. It is an exhibition which is grounded: grounded in Ōtautahi – a place that connects to his own history as a boy growing up in Canterbury and his training as an artist, grounded in the space of the gallery – which becomes expanded and reconsidered as a site – and grounded in the space between work and viewer where meanings are continually being negotiated and constructed.

Fieldwork marks Robinson’s return to Ōtautahi, this being his first solo show in the city since the earthquakes. In 2017, he was a contributing artist to the Paemanu: Nohoaka Toi exhibition (also held at CoCA), which saw his brightly coloured felt forms hanging high and low on the gallery walls as if bouncing around the space. Fieldwork, however, offers a new body of work, one which Robinson has developed directly in response to the site. Woven throughout it are purposeful connections to the region that reference his personal history and gesture towards an exploration of twentieth century art historical discourse. Having grown up on a farm in Ashburton before moving to Ōtautahi to study at the Ilam School of Fine Arts, this idea of ‘fieldwork’ seems appropriate as a title and a concept through which to consider his work. It references a landscape – multiple landscapes in fact – as he constructs visual fields which are sparsely punctuated by his sculptural forms on the floor, walls and ceilings, and follow no discernible pattern while continually disrupting your gaze as you move through the space. One work in particular evokes the farming fields of the Canterbury plains, as hundreds of silver galvanized wires have been haphazardly placed on the ground mimicking a pile of hay. The lustrous quality of the wires reflects the light and catch the eye from a distance, again bringing attention to the expansive space which they occupy. The hanging grids which dominate the space in the Mair gallery can also be read as alluding to the grid layout of the city. They create a referential landscape that connects to the colonial history of Ōtautahi and ground the exhibition within the city, past and present, as the gallery itself has not shifted from its original position within the four avenues.

Furthermore, the materiality of the works themselves contribute to the construction of invisible fields, such as those created by the magnetic sculptures in the exhibition. These magnetic components literally anchor the works in the space as their magnetic attraction is often solely responsible for their attachment to the building and between the individual components of the work itself. This makes their position precarious, and subject to the viewer’s understanding of the forces at play as some people, for example those with pacemakers, will be directly impacted by something that remains invisible to the eye but dictates their movement through the space.

‘Fieldwork’ as a title also frames the exhibition in a way which acknowledges the processes behind its making. In the lead up to the instillation, Robinson made multiple visits to the gallery to explore the building and surrounding areas, which have changed considerably over time.  This research-based approach around the context that he is working within extends beyond the physical and considers the many artistic influences which inform his practice. Artists such as Richard Tuttle and Nora Schultz, whose sculptural practices incorporate found or readily available industrial materials like metal rods, tubes, and discarded wood which combined with the simple manipulation of these materials within the gallery space brings them into conversation with Robinson’s work. The audience too becomes an important part of this conversation. Thinking about the concept of fieldwork in relation to this exhibition clearly positions the audience as active participants in the collection and use of the information presented throughout it. Visitors to the gallery are bringing their own bias and knowledge into the space and drawing their own conclusions. It is a reminder that the nature of fieldwork – and the way we experience art of any kind – is always multi-directional and subjective as it is unable to be removed from the self. This element of self-reflexivity is encouraged as it makes space for constant reinterpretation of the works and acknowledges both internal and external influences which frame peoples experience of the exhibition.

Fieldwork also offers a refreshing treatment of the gallery space which has previously hosted massive and highly immersive exhibitions. The brutalist building – a fine example of the Christchurch Style and designed by Minson, Henning-Hansen and Dines – was purpose built as a gallery, and as such, offers a lot of light, height, and wall space with which to play around with. At first, Fieldwork appears to push back against this by having works that appear disproportionate in scale to the space and some that are scattered in dimly lit corners or obstructed by the architecture itself. Such tactics bring attention to the architectural features of the space which might otherwise go largely unnoticed or be perceived as being disconnected from the works on show. Robinson’s sculptural forms respond to the architecture in playful ways and remind the viewer that this is an active space. Long, textured, and anodized aluminium rods lean against the corners of the gallery and draw the eye up towards the ceiling, emphasising the point at which the two walls converge. Similarly, the wire work in the Ground Floor Gallery which is attached to a metal sprinkler pipe on the ceiling, as well as the work situated in the lift, bring attention to the services of the building and hint at its human occupation. Being reminded of this as people make their way around the show acknowledges the fact that it is more than an exhibition space – it is a workplace, a site of leisure and entertainment, and a site with its own history of which Fieldwork is only a small part of.

In other ways, the interplay between the sculptures and the architecture can also make something less visible. For example, a work made from very thin white wire blends into the surrounding white wall and is only revealed when people move closer to it. Another sculpture sits on the stairs between a wall and a glass divider and its reflection, as opposed to the object itself, is slowly revealed as people turn the corner. The careful placement of these works encourages people to slow down and consider them more closely, which is refreshing given the fast-paced approach to almost everything else in modern society. This idea of objects hiding in plain sight also contributes to the sense of playfulness that runs throughout the exhibition and it reminds us how reliant we are on the cues given by the built environment when navigating the space.

In a more subversive move, Fieldwork spills outside the galleries and pushes back against the museological convention of displaying works within a few designated areas. There are sculptures scattered throughout the building that occupy liminal spaces such as stairways, toilets, a fire corridor, and a balcony. Some of the works are easy to spot and draw attention to themselves through their bright colouring and prominent placement, but others are tucked away in dim or inconspicuous corners of the building which have been previously inaccessible to the general public. Free movement throughout the entire space is encouraged but is again mediated in subtle ways, and perhaps carries with it some anxieties around encountering these sculptures in places that might not necessarily be seen as ‘spaces of art’. Gallery maps and arrows also guide people to the works like a treasure hunt which removes the possibility of a chance encounter, and glass doors and rope barriers section off specific works from the viewer. The responsive nature of this exhibition means that the architecture has a large role in dictating the placement of the works and therefore should not be seen as something which is independent from the rest of the exhibition. By having works scattered throughout the building, the space is conceived of as a whole and people are invited to examine the gallery space in greater detail and look at it more conceptually, question where it begins and ends (if such judgements can be made at all), and consider why this ambiguity might be uncomfortable given the lasting influence of the white cube model of display.[1]

As a viewer, it’s impossible to remain passive when encountering Fieldwork. Curiosity, and to a degree, confusion encourage people to look closer, move further into the field laid out in the space, and decipher in their own way the visual language presented by Robinson. The participatory quality of the show is best demonstrated by the heightened sense of bodily awareness people gain when attempting to navigate the space. Their carefully choreographed movements are interrupted by moments of unpredictability when they are ambushed by a work as they turn corners, open doors, or shift their gaze. Even private moments are fair game with works waiting to be uncovered in the toilet cubicles. Such encounters urge visitors to spend time with the work and find their own ways of connecting to it. The exhibition is participatory not in the sense that it is tactile, but because it acknowledges that looking is not a passive act, particularly when followed by a conscious effort to comprehend what is in front of us, how it is framed, and how this feeds into the overall perception of the exhibition.

Although the element of surprise is, for the most part, a luxury afforded to first time visitors to the exhibition, Fieldwork continues to offer new ways of interacting with space and form with every visit. By occupying what is often considered to be an authoritative cultural space, his forms may appear certain in their status as ‘art objects’ within the gallery, but they are bringing into question the space itself and reflecting on the histories of modernist sculpture which are entangled with contemporary art spaces and practice. CoCA, with its long history in Ōtautahi and an institution which has found its place in Robinson’s own career as a Fine Art student and now as a practicing artist, seems like an appropriate setting for these conversations. The thoughts which arise from spending time amongst Fieldwork are not always coherent, but nor do they have to be. As a visitor, any frustration at this incoherence or the caution with which you have to move throughout the space and be constantly alert is undercut by the sense of playfulness of being caught in a perpetual game of hide-and-seek with his sculptures.

[1] The ‘white cube’ model has become the most common method of displaying modern and contemporary art in the Western museological tradition. It is often characterised by galleries with white walls, even lighting, ample room between artworks, and offers minimal descriptive information about the works on display. Its supposed neutrality has been (and continues to be) heavily critiqued, however, the ideology of the white cube remains pervasive today. For a detailed discussion into the development of the white cube as a display format please see Brian O’Doherty’s essay “Notes on the Gallery Space” in his book: Inside the White Cube: The Ideology of the Gallery Space.

What You Should Learn About Wire Drawing Machine

The types of wire drawing machine include vertical drawing machine, chain-type drawing machine, roller die drawing machine, horizontal drawing machine and pully-type wire drawing machine, mainly used for drawing steel wire, copper wire and aluminum wire. During the drawing process, the steel wire and the surface of the reel do not slide relative to each other in the circumferential direction of the reel and the surface wear of the two is relatively small. When a certain reel is temporarily stopped in the middle, the customers can still rely on their respective product volume to work as usual. The drawing machine has the advantages of simple structure, convenient operation and maintenance, and low manufacturing cost. It has features of large low-frequency torque with stable output, the proportional linkage control with high accuracy, slip compensation function, high-speed accuracy, maintaining constant tension and preventing disconnection.

Vertical Drawing Machine

With the vertical downward working mode of the reel outlet, 1-3 tons of wire can be continuously drawn by vertical drawing machine at a time. The equipment has the dual functions of drawing and take-up. It is suitable for high, medium, low carbon steel, special-shaped steel wire and other non-ferrous metal wire. The machine ia applied for drawing wire in the factories,such as wire-steel factor,metal mesh factory and nail making factory etc. In order to lower residual heat on the surface of the block, the cooling means is installed in inter-wall of the block,the wortle is soaked in cooling water to reduce its working temperature.

Chain-Type Metal Pipe Bar Drawing Machine

Chain-type pipe drawing machine is suitable for the drawing of tube material. The metal drawing machine enters into the center frame mold after passing through the feed end of the raw material. After being clamped by airpower, the chain hook pulls the chain. When the material is drawing, it requires the little vibration on the main body and the uniform stable pulling speed. The best precision of the finished product is achieved. The finished product has a smooth surface and even high quality and it is usually stretched to meet the setting requirements.

Horizontal Rebar Wire Rod Drawing Machine

Horizontal wire drawing machine enables the steel bar to pass through the wire drawing die from different directions at one time. It can be used in three-ribbed rolling mill. The steel bar after the drawing is directly introduced into the rolling mill for getting a three-ribbed threaded steel bar. The machine is equipped with a 30KW motor. Compared with the continuous pully-type wire drawing machine, the machine has the characteristics of small floor space, energy-saving, simple operation and high production efficiency.

Multi-Drums Wire Drawing Machine

The wire drawing machine is mainly used for drawing steel wire, copper wire and aluminum wire. It is also called pully-type wire drawing machine and are divided into two drums, triple drums, four drums, five drums, or customized. It has the advantages of high production efficiency, quick drawing speed, small floor occupation, low investment, and easy operation. The machine has a significant energy-saving effect and can save a large amount of electric power for users and is mainly used for weaving net, water tank drawing, construction, galvanizing, etc.

alve Selection and Application Guidelines

July 3, 2017

P.Eng.

Meena Rezkallah

The following guidelines are provided to assist in selecting a suitable valve for any application. These guidelines are intended to cover all physical features and capabilities or limitations of different types of valves and which may be suitable for one particular application. The user must fully evaluate the pros and cons of using a particular type of valve and arrive at the most suitable selection, taking into consideration the life span expected and costs involved.

Identify  Application Characteristics

Identify the system and various modes of system operation: startup, normal operation, accident condition, standby, shutdown, et cetera.

Identify the flow medium and its properties, flow rate during all modes of system operation, system design pressure, and design temperature.

Identify the pipe size, pipe wall thickness, piping material, piping joint(s) to be used, and any other information which relates to valves in the system.

Establish the code of jurisdiction, which governs the construction of the system, component, or equipment. The codes related to piping systems are discussed in Chap. A4. The applicable code (ASME B31.1, B31.3, B31.5, B31.8, B31.9, B31.11, ASME Sec. I, Sec. III, Sec. VIII, etc.) does contain requirements for valves. Become familiar with the code requirements for valves in general and for the system under consideration in particular.

Identify the valve standards referenced in the code of jurisdiction. Each code lists the valve standards that are acceptable for construction of valves to be used in piping within the jurisdiction of the code. Use valves complying with the valve standards listed in the code of jurisdiction. The most commonly used valve standards are listed in the beginning of this chapter.

Establish the pressure drop through the valve that can be critical on overall system performance. For example, the pressure drop through the stop valve(s) in the main steam system of a power facility is critical to achieve the guaranteed performance of the plant.

Select Type of Valve Required

In reference to the various modes of system operation, determine the func- tion(s) a valve has to perform.

Based upon the valve functions, the valve type(s) can be selected. The valve needed may be an isolation valve or a stop valve. What are the choices available?

Similarly, the valve required may be a check valve or the valve required to stop the flow in reverse direction. There are many different types of check valve. Which is the most suitable?

Does flow need to be throttled? Based upon the amount of throttling required, one may select a globe valve, butterfly valve, or a needle valve. Size limitations  also play a role in the availability of these    valves.

If flow has to be regulated and controlled based on variation in pressure, temperature, fluid level, or the design limitations of a component or   equipment, the valve required would be a control valve.

The first step is to determine the valve type: isolation, check, or a control valve. If the component or the piping system is required to be protected against overpressure built up, then one of the pressure-relief devices ought to be selected.

To begin the selection process, Table A10.11 provides a good starting point.

The next step is to narrow down the choices of valves to be used. As discussed earlier, there are several different designs available in different categories of valves. For example, large-size butterfly valves are preferred to large-size gate valves as stop valves in low-pressure and low-temperature cooling water systems, due to space, weight, actuator, and cost considerations

Select Valve Size

Pipe size will indicate the valve size unless there are other requirements that may make it necessary to install a smaller- or larger-than-pipe-size valve.

The valve availability is one of those factors. In addition, some valves are not manufactured in certain small or large sizes. Refer to valve vendor catalogs and evaluate application requirements and valve features in addition to space, cost and, operational concerns.

Select Valve-End Connection

Types of piping joints to be used depend upon several considerations, such as ease of removal and replacement of components in the piping system, frequency of repairs and replacements, life span of valves, and trim items. For example, the power plants utilize welded joints, whereas the petroleum refineries and chemical plants use flanged joints predominantly. Use of threaded, soldering, and brazing joints is common in plumbing piping systems.

Check code requirements concerning piping joints. At times codes prohibit or restrict the use of different types of joints based upon size, pressure, temperature, materials of construction, flow medium, and other criteria. When leakage through joints is a concern, use of a threaded joint may be prohibited or limited by the code or by prudent engineering.

When valve-body material is different from the pipe material, transition pieces may be needed to attach the valve to  piping.

To prevent galvanic corrosion between valve and pipe flanges, insulating flanges may be  needed.

Select Valve-Body, Bonnet, and Trim Materials

Flow medium and its characteristics will help in selecting the valve-body and valve-trim materials. The flow-medium characteristics include: liquid, gaseous, vapor or two-phase flow, viscosity, clean fluid, dirty fluid, suspended impurities, pH- value (0 to 14), and pressure, and temperatures during different modes of system operation. Nonmetallic, stainless steel, or high-alloy piping may be utilized. Accord- ingly, valve materials should be selected keeping in mind the manufacturing limita- tions and availability of valve types and sizes    required.

Flow rate will dictate requirements for the valve-flow coefficient. Should the valve be full port, standard port, reduced port, et  cetera?

Valve materials for pressure-retaining parts must be in accordance with the applicable code and acceptable valve standard.

Materials for valve parts other than pressure retaining parts must be suitable for withstanding all conditions of loading and assist the valve in performing its design functions.

Identify Seat-Leakage Criteria

Determine the minimum and maximum acceptable seat leakage across the valve seat when the valve is in closed position during various modes of system operation. In some cases the seat leakage may not be of concern, while in other applications, such as in piping handling cryogenic fluids, radioactive materials (liq- uids, gases, and mixtures) or toxic and hazardous waste materials may be a serious concern and must be limited to an acceptable level.

The applicable valve standard may specify the acceptable seat leakage when the valve is tested in the shop. Alternatively, more stringent criteria may be specified. Refer to the valve standard, such as MSS SP-61 and API 598.

Identify Requirements for Valve-Stem Packing Arrangement

If the valve is to be connected to a piping system or to equipment which is continuously maintained at vacuum, the stem packing must be suitable to prevent inward air leakage. Inverted–V Teflon packing is used to temperatures up to 400°F. Graphite packing may be specified at temperatures above 400°F. Contact the valve manufacturer to ensure effectiveness of the packing.

When fugitive emission is a concern, specify the requirements for a suitable packing arrangement. In cryogenic applications the leakage of fluid across the valve seat must not come in contact with the stem packing.

Take into Consideration Maintenance Requirements

Maintenance considerations are important for the selection of valves. The plant designer must provide for access, assembly, and disassembly of valves.

Space limitations may impose restrictions on the use of a particular type of valve even though it may be the most suitable valve for the application. Select an alternative valve.

When plants are designed for long life, the valves selected must not require frequent maintenance, with the exception of items such as the replacement of  packing or lubrication.

Initial Cost

A low-initial-cost valve may necessitate frequent repairs or replacements of the valve or valve parts. Be aware of future costs involved.

High initial costs may be prohibitive. Therefore, a compromise may be made to choose the right valve for the application.

Actuation Requirements

Does the valve require an actuator? If needed, select the proper actuator, keeping in mind the facilities and utilities available at the location.

Failure mode desired will dictate the type of power actuator.

Gear-actuated valves require special attention with regard to the size of the actuator. The actuator size would depend on the maximum rim pull that can be applied without use of crowbars, rods, or hammers. The rim pull may vary from as low as 50 lb (22 kgf) to 250 lb (113 kgf). Consideration must be given to the plant-operating individuals and their safety and health. A high rim pull may result in injury to an operator.

The above-stated guidelines are provided to assist the user in arriving at a reasonable solution for selecting and applying valves. They are not to be considered the only guidelines. They are for initiating the thought process and offering users critical information for making a final decision. #Little_PEng

Usage of Different Kinds of Threaded Steel Bar

SUMMARY

Threaded steel bar materials are classified according to tensile strength—it is generally calculated that how much degree of resistance do it break under the tension. However, there are many other different kinds of specifications for steel grades, which include ASTM, AISI, and SAE International.

Picture Courtesy:- Wikipedia

Materials

Threaded rod is produced from a variety of materials.

The most common material for threaded bar is steel, passing over variety of alloys, strength, and hardness. Threaded steel bar can be coated or uncoated, with zinc being one of the most  common coatings for electro-plated and hot-dip galvanized threaded rod. There are many  common metallic materials used to make threaded rod which include aluminum, brass, copper, and silicon bronze. There are also many non-metallic materials such as plastic, nylon, and synthetic rubber which can also being used to make threaded steel bar.

Not all threaded rod is made equal.

Depending on the application and industry, certain materials are preferred. For high-temperature applications, Because of its tensile strength Grade B7 is in high demand therefore of its tensile strength, excellent heat resistance and resistance to corrosion.

Some of the materials for threaded rod are listed below, starting with steel rod types and finishing with many other metals.

Steel Threaded Rod Grades

Low Carbon Steel

Due to its versatility one can say that low carbon steel is the most common material throughout the threaded rod industry. There are different grades of low carbon steel to meet the minimum tensile and yield strength requirements of ASTM A307 including 1008, 1018, & 1022. The mild steel certificate shows that the varying chemical composition limits of each grade. It is very much easier to shape because of the malleability of the metal. This makes it the ideal material for bending and manufacturing products such as U-bolts. The material is also used across a variety of industries because of its weldability.

Grade 8 is a medium of carbon or alloy steel, and has one of the highest tensile strength available, even higher than B7. Grade 8 is generally used for threaded bolts in highly in demand such as automotive suspensions for large trucks and tractors.

Stainless Steel Threaded Rod Grades

304 SS

Stainless Steel 304 is a kind of stainless steel which consist of at least 18% chromium and 8% nickel, and also up to 0.08% carbon. Generally this kind of steel is the most common of the 300 series stainless sheets. Because of the chromium content it can resist oxidation as well as corrosion. Due to the high corrosion-resistant properties, it is mainly used in the appliance industry for its aesthetically-pleasing appearance.

316 SS

Stainless Steel 316 is a highly corrosion-resistant stainless steel which is very much similar to 304SS. This is one of the highest grades among the common stainless steel. In addition to chromium and nickel, 316 SS also contains molybdenum which helps in the resistance of chlorides. Stainless Steel 316 is usually used for projects in the marine environment where salt water is involved.

18-8

18-8 is a term which is inherited by the name its name from the 18% chromium and 8% nickel content. 18-8 is not a grade which is usually used to call out fasteners made from 300 series stainless steel, which have varying levels of this mixture. 18-8 series fasteners are mainly used to prevent rust in applications where moisture is constant, like breweries and many more places.

Other Metal Threaded Rod Grades

Brass

Brass is a kind of alloy made up of copper and zinc. Brass is also very much easier to manufacture and it is also corrosion resistant. Brass generally has a bright, gold-like appearance that makes it perfect for certain projects like plumbing and electrical applications which are visible.

Aluminum

Aluminum is a lightweight, chemically stable metal which is naturally corrosion resistant. Aluminum is also known for being very soft, non-magnetic metal which is easily formed. Due to its lightweight, it is commonly used for threaded products in many Industries.

Silicon Bronze

It consists of around 96% of copper and is also a low-lead brass alloy. Due to its surface finish, high strength, and superior corrosion-resistant properties it is very much attractive to the electrical, marine, and energy industries.
