What is Braided Gland Packing?

A sealing substance used to stop leaks in rotating or reciprocating shafts is braided gland packing, commonly referred to as compression packing or simply packing. A dense, flexible, and durable packing material is created by weaving together various fibres, such as aramid, carbon, graphite, PTFE, or synthetic materials.

Construction and Types:

Usually, separate fibres are braided together to create the braided gland packing. The packing's characteristics, such as its flexibility, robustness, and resistance to various operating circumstances, are determined by the amount of fibres and the precise type of braiding.

Common types of braided gland packing include:

a) Pure PTFE Packing: This packing is made from 100% pure PTFE fibres and is ideal for sealing applications involving corrosive fluids. It offers outstanding chemical resistance.

b) Graphite packing: To improve heat conductivity and lubricating qualities, graphite fibres are frequently combined with other substances like carbon or aramid. For applications requiring high temperatures, graphite packing is excellent.

c) Aramid Packing: Packing made for applications involving high pressures and abrasive environments uses aramid fibres, which are recognised for their strength and endurance.

d) Carbon packing: Excellent thermal and chemical resistance is provided by carbon fibres. Pumps and compressors are two examples of high-speed rotating machinery that frequently use carbon packing.

Advantages of Braided Gland Packing:

a) Versatility: Braided gland packing can be used in a variety of settings, including pumps, valves, mixers, and agitators. Water, oil, chemicals, and gases can all be efficiently sealed with them.

b) Leakage Control: Braided gland packing ensures dependable sealing, reducing the possibility of fluid leakage, and preventing environmental contamination thanks to its dense structure and capacity to adhere to the shaft surface.

c) Adaptability: Braided gland packing's ability to adapt to shaft misalignment, radial motion, and equipment vibrations results in a tight, long-lasting seal.

d) Cost-Effectiveness: Braided gland packing is typically more inexpensive and simpler to install than mechanical seals. When correctly chosen and installed, it may last a long time with little care.

Common Applications:

Braided gland packing finds applications in numerous industries, including:

oining Ductile or Cast Iron Pipe

May 27, 2017

P.Eng.

Meena Rezkallah

Bell-and-Spigot Joint

This joint for underground cast-iron pipe was developed as long ago as 1785. Standard dimensions are shown in Table A2.22.

The joint may be made up with lead and oakum, sulfur compounds, or cement. Lead and oakum constitute the prevailing joint sealer for sanitary systems. Bell- and-spigot joints are usually reserved for sanitary sewer systems. These joints are not used in ductile iron pipe.

Mechanical (Gland-Type) Joint

This modification of the bell-and-spigot joints, as designated in Federal Specification WW-P-421 and ANSI/AWWA C111/A21.11, is illustrated in Table A2.23.

This joint is commonly used for low and intermediate-pressure gas distribution systems, particularly those conveying natural gas or dry manufactured gas. Mechanical joints are also used for water lines, sewage, and process piping. In the mechanical (gland-type) joint shown in Fig. A2.30,

the lead and oakum of the conventional bell-and-spigot joint are supplanted by a stuffing box in which a rubber or composition packing ring, with or without a metal or canvas tip or canvas backing, is compressed by a ductile cast-iron follower ring drawn up with bolts. In addition to making an inherently tight joint even under considerable pressure, this arrangement has the advantage of permitting relatively large lateral deflections (3¹⁄₂° to 7°), as well as longitudinal expansion or con- traction. For more details, refer to AWWA C600, Standard for Installation of Ductile-Iron Water Mains and Their Appurtenances.

Tyton Joint

The Tyton joint is designed to contain an elongated grooved gasket. The inside contour of the socket bell provides a seat for the circular rubber in a modified bulb- shaped gasket. An internal ridge in the socket fits into the groove of the gasket. A slight taper on the plain end of the pipe facilitates assembly.

Standard dimensions are given in Table A2.24. The maximum joint deflection angle is 5° for sizes through NPS 12 (DN 300), 4° for NPS 14 (DN 350) and NPS

16 (DN 400), and 3° for NPS 18 (DN 450), NPS 20 (DN 500), and NPS 24 (DN 600). Either all-bell U.S. standardized mechanical joint fittings or bell-and-spigot all-bell fittings with poured or cement joints can be used with Tyton joint pipe.

Mechanical Lock-Type Joint

For installations where the joints may tend to come apart owing to sag or lateral thrust in the pipeline, a mechanical joint having a self-locking feature is used to resist end pull. This joint is similar to the gland-type mechanical joint except that in the locked joint the spigot end of the pipe is grooved or has a recess to grip the gasket. Although only slight expansion or contraction can be accommodated in this type of joint, it does allow the usual 3¹⁄₂° to 7° angular deflection. The lock-type joint finds application above ground in the process industries and in river crossings on bridges or trestles, as well as in submarine crossings or in unusually loose or known marshy soils. Where the locking feature is on the spigot rather than on the bell, this type of pipe can be used with the regular line of mechanical joint fittings.

Mechanical Push-On-Type Joint

Where a low-cost mechanical joint is desired, the roll-on type can be used. In this joint, a round rubber gasket is placed over the spigot end and is pulled into the bell by mechanical means, thus pulling the ring into place in the bottom of the bell. Outside the rubber gasket, braided jute is wedged behind a projecting ridge in the bell. This serves to confine the gasket under pressure in the joint. A bituminous compound is used to seal the mouth of the bell and to aid in retaining the hemp and the rubber gasket. Either bell-and-spigot or mechanical (gland-type) fittings are used with this line of pipe. Push-on joints are made in accordance with ANSI/ AWWA C111/A21.11.

Mechanical Screw-Gland-Type Joint

This type of mechanical joint for cast-iron pipe makes use of a coarse-threaded screw gland drawn up by means of a spanner wrench to compress a standard rubber or composition packing gasket. The joint allows from 2° to 7° angular deflection, as well as expansion or contraction without danger of leaks. A lead ring, inserted in the bell ahead of the gasket, seals off the contents of the line from the gasket. The ring also provides an electric circuit through the joint for thawing out frozen underground mains and service lines by the electrical method. The screw-gland joint is used in piping which conveys water, gas, oil, and other fluids at considerable pressure. The gaskets and lead rings are interchangeable with those used in equivalent lines of mechanical joints of the bolted-gland type. A full line of fittings is available for use with screw-gland pipe.

Ball-and-Socket Joints

For river crossings, submarine lines, or other places where great flexibility is necessary, ductile cast-iron pipe can be obtained with ball-and-socket joints of the mechanical-gland types, as shown in Fig. A2.31.

Provision is made for longitudinal expansion and contraction, and a positive stop against disengagement of the joint is a feature of the design. As much as 15° angular deflection can be accommodated without leakage. This pipe is heavy enough to remain underwater where laid without requiring river clamps or anchorage devices. The pipe may be pulled across streams with a cable, since the joints are positively locked against separating, or it may be laid directly from a barge, bridge, or pontoons, without the services of a diver. The mechanical ball-and-socket joint is suitable for use with water, sewage, air, gas, oil, and other fluids at considerable pressure. Either bell-and-spigot or mechanical (gland-type) fittings can be used with this line of pipe, although the integral ball present on the spigot end of some designs has to be cut off before the pipe can be inserted in a regular bell.

Universal Pipe Joints

This type of cast-iron pipe joint (shown in Fig. A2.32)

has a machined taper seat which obviates the need for caulking or for a compression gasket. The joint is pulled up snugly with two bolts, after which the nuts are backed off slightly, thus enabling the lock washers to give enough to avoid over stressing the socket or lugs. Pipe is made in 12- to 20-ft (3.5 to 6-m) lengths to the usual pressure classes and can be bought as Type III under Federal Specification WW-P-421. Universal-joint fittings are available for use with the pipe. This type of joint is used to some extent in pipe diameters of NPS 4 (DN 100) to NPS 24 (DN 600) for underground water supply systems; but it is not considered suitable for gas service, and it does not permit much angular displacement or expansive movement.

Compression-Sleeve Coupling

The type of joint shown in Fig. A2.33 is used with plain-end pipe of either cast iron or steel. It is widely known under the trade names of Dresser coupling and Dayton coupling. Compression sleeve couplings are used extensively for air, gas, oil, water, and other services above- or underground. With a joint of this type, it is necessary to anchor or brace solidly at dead ends or turns to prevent the line from pulling apart. Compression couplings and fittings with screwed packing glands are available for use with small-size cast-iron or steel pipe. In welded transmission lines for oil or gas where any significant change in temperature is expected, a certain percentage of the joints may be made up with compression couplings instead of welding in order to allow for expansion.

Grooved Segmented-Ring Coupling

The type of split coupling shown in Fig. A2.34 is used with either ductile cast-iron or steel pipe that has grooves near the ends which enable the coupling to grip the pipe, in order to prevent disengagement of the joint. The couplings are manufactured in a minimum of two segments for small pipe sizes and several segments for large pipe sizes. Grooved-end fittings are available for use with the couplings. With proper choice of gasket material, the joint is suitable for use above- or underground with nearly any fluid or gas. The joint’s advantages are its

Ability to absorb minor angular and axial deflections

Ability to increase gasket sealing force with increased system pressure

Refer to AWWA C.606, Standard for Grooved and Shouldered Joints.

Simplicity for rapid erection or dismantling for systems requiring frequent disas- sembly.

The coupling is also available in a style where grooving of the pipe ends is not required. Joint separation is prevented by the use of hardened steel inserts (teeth) which grab the mating pipe ends.

Flanged Joints

Flanged ductile or cast-iron pipe is used above ground for low and intermediate pressures in water-pumping stations, gas works, power and industrial plants, oil refineries, booster stations for water, and gas and oil transmission lines. Cast iron flanges usually are faced and drilled according to ASME B16.1. For flanged joints in a ductile iron pipe, refer to ASME B16.42, ANSI/AWWA C110/A21.10, C111/ A21.11, C115/A21.15, and C153/A21.53. Cast-iron pipe is made both with integrally cast flanges and with threaded companion flanges for screwing onto the pipe (as shown in Figs. A2.35 and A2.36).

In the latter case, the outside diameter of the pipe conforms to iron pipe size (IPS) dimensions to allow for the threads provided. It is available in sizes NPS 3 (DN 50) through NPS 24 (DN 600) and in length to 18 ft (5.5 m). For lengths less than 3 ft (1 m), in sizes NPS 3 (DN 50) through NPS 12 (DN 300), the flanges may be cast integrally with the pipe, rather than screwed on the pipe, at the manufacturer’s option.

Standard dimensions of flanged joints for silver brazing are shown in Table A2.25.

All About Pure PTFE Packing

Summary

Picture Courtesy: JDJones

Many manufacturers use PTFE as the base fiber for packing styles. These packing style may be supplied as dry fibers, fibers coated with PTFE dispersion, or fibers coated with various lubricants. Use these products only where there is no other PTFE alternative for the service, including applications with very aggressive chemicals, such as strong oxidizers.

Consult a packing manufacturer to determine what specific styles are suitable for particular services. With PTFE fiber packing it is important to follow the manufacturer’s instruction regarding limits for temperature, speed, and pressure. When used in rotating equipment, these can be very sensitive to adjust.

Typically, lower gland pressure is needed and higher leak rates are experienced than with other packing styles.PTFE Packing or Teflon Packing is braided with high purity PTFE (Polytetrafluoroethylene, Teflon) filament. PTFE material has an advantage like low friction and excellent resistance to chemicals.

PTFE Braided Packing is resilient, chemical resistant, self-lubricating, and withstand the high linear speed and pressure with minimum wear to the shaft. It is good for high-speed applications that require clean and minimum contamination material.

Applications of Pure PTFE Packing Absence of oil so recommended in areas where there is danger of combustion. Used in pumps & valves having low shaft speed. Recommended in equipment handling hazardous & corrosive chemicals. Fast & simple to install with minimum maintenance requirements. PTFE packing has particular characteristics such as low coefficient of friction, high chemical resistance, and excellent tightness, making it suitable for static, rotary & reciprocating applications.

RUBBER CORE PTFE PACKINGS WITH PTFE DISPERSION:

PTFE packing can be made available with silicon/rubber solid or hollow core. A specially developed Teflon packing for use on rotating equipment with excessive shaft deviation. We are manufacturers, suppliers, and exporters of PTFE packing and dispersion in Mumbai India to all over the world. It also reduces shaft/sleeve wear. Teflon packing is suitable for pumps, reactors, mixers, agitators, etc.

Unique properties of Pure PTFE Packing Excellent chemical resistance. A major reason for using PTFE is that it is unaffected by a wide variety of aggressive fluids, including very strong acids, bases, and solvents. Most important is PTFE’s ability to withstand strong oxidizers such as nitric acid, chlorine dioxide, high concentration sulfuric acid, and others. PTFE may be the only feasible option for applications involving these media.

PTFE Coated Packing When the chemical resistance of pure PTFE is not required, many fiber materials can be coated with PTFE to improve packing performance. These fibers help to reduce or eliminate some of the weaknesses of a pure PTFE braid. Blended synthetic and fiberglass yarns can be coated with PTFE to produce economical, general service packings that exhibit higher resilience, greater extrusion resistance, and less sensitivity to adjustment than a PTFE fiber braid. They sometimes coated with a dispersion mixture of PTFE and graphite to increase the speed capability and heat dissipation characteristics of the braid. Aramid fiber packings with a PTFE coating can be used in applications requiring extreme abrasion resistance.

Technical Parameters Temperature: -200oC to +260oC pH Range: 0-14 Pressure: 100 Kg/Cm2 Velocity: 5 Meters / Second

Conclusion The packing made from expanded PTFE, completely chemically inert, unshrinkable, with very low factor of friction and factor of compression. Recommended conditions use-static condensation. It is suitable for all chemical mixes (except for alkaline metals and gaseous fluorine), the shaft of rotation working at low peripheral speed, rods, pistons, various connections, Is, etc. Applied to pipeline armature and low-speed shaft under average pressure in processing foodstuffs, pharmaceutical production, paper crushers where high cleanliness and stability against corrosion is required.

When you insert the material of Inconel wire and fiberglass filaments which are inherited into the yarn to increase the tensile strength of the fabrics of both before and after the exposure to heat. Usually applications include gaskets, seals, pipe wrapping, furnace and welding curtains.

Round and Square Ceramic Fiber Braid are also been manufactured by over-braiding around a core of ceramic fiber to receive the maximum resistance to mechanical abuse with a density range of 33-36 PCF. In addition to its superior strength, round and square braids also exhibit minimal unraveling when it is being cut.

Advantages:

Amazing chemical stability and resistance, specially excluding the hydrofluoric & phosphoric acids or you can say concentrated alkalis.

It has very strong resistance to thermal shock and corrosion.

When it is wet by water or steam, thermal properties are completely restored upon drying.

Resistant to oxidation and reduction.

A huge variety of textiles are produced either by converting ceramic blanket or by processing refractory ceramic fibre yarn into woven products. Ceramic fibre textiles are perfectly match for the use of elevated temperatures which is approaching 1400°C, maintaining the flexibility for use in thermal sealing and filling applications in those areas for example door seals, expansion joints and gland packings.

Mechanical shaft seals will ensure your work doesn’t stop

Seals and gaskets are the backbones of the Industrial sector. They are the golden key for ensuring smooth and break less work. They help in the production of contaminant-free liquid and gas processing by making sure everything is divided. They are anti-leak; create a partition between chambers and surfaces. There are a wide variety of industrial applications which require custom seals and gaskets. They are required to meet each application's specific needs. We all know that a mechanical seal is a method of containing fluid within a vessel. It works on this principle for pumps, mixers where a rotating shaft passes through a stationary housing. Such a seal should be strong, durable and anti-leak. They have a unique function in its applications and all of its functions are feasible due to the method they are made of. There is more than one way to seal a pump but are various methods of forming Mechanical Shaft Seals. One among them is still widely used and is referred to as the gland packing. The gland packing is braided, in a rope-like material that is packed around the shaft. It physically stuffs the gap between the shaft and the pump housing making it fit for the application. Seal Sales design and manufactures a variety of sealing solutions for their industry as well as individual clients. Have a look at all the products and purchase the one which fits into the application.

Advantages and Disadvantages of Graphite Packing

It is easy to confuse graphite fiber packings with carbon fiber packings. In fact, the terms carbon fiber and graphite fiber are often used interchangeably, even by packing manufacturers. Both products are used to manufacture braided packings, and they both have relatively good chemical and temperature resistant properties. But there are differences, and each has its advantages and disadvantages.

Properties of Carbon and Graphite Fibers

Typically, carbon fibers have excellent strength and toughness and are considerably less expensive to manufacture. Since carbon fiber based packings are generally tougher than graphite, they are more resistant to abrasive media. They also have the ability to handle the higher compressive loads that are required for high pressure services.

Graphite packing fibers may approach the strength of carbon, but have improved lubricity and, as such, are not so abrasive. When formed into packing that is used to seal rotating shafts, graphite can operate at higher shaft speeds with less leakage. Graphite fiber packings also have better thermal conductivity than carbon fibers, meaning they can better dissipate any frictional heat that is generated. These properties make them ideally suitable for clean media, high shaft speed services, such as boiler feed pumps.

Carbon and graphite fibers are both composed of elemental carbon, but with distinct characteristic differences. These property differences are primarily created by the raw materials from which the fibers are made, and the type and extent of thermal processing.

Historically, one major distinction is that graphite fiber typically has carbon content greater than 95 percent. Graphite fibers more closely approach the purity and properties of crystalline graphite, while carbon is far less crystalline, so is often called "amorphous." A lump of coal and a fine diamond are both made from carbon atoms, but their elemental structure is quite different. This makes them both valuable, but for different reasons.

Both graphite and carbon fibers are made from one of three precursors or raw materials: polyacrylonitrile (PAN), rayon, or petroleum pitch fibers. All three of materials are organic polymers in fiber-form that are heated, initially in air in certain cases, then ultimately to high temperatures in furnaces without air to prevent oxidation during processing. This process is called "carbonization."

After carbonization, the graphite fibers are heated again to much higher temperatures to enhance crystallinity, carbon content, and purity. These fibers, in yarn form, are then subjected to various treatments such as "sizing" or coating.

Graphite Packing Fabrication

When large numbers of fibers are combined (typically by twisting them together), they form yarns. The yarns are then braided into various forms and sizes of packing after coating with specific sizing agents, such as PTFE, that serve to aid braiding as well as enhance ultimate sealability.

A disadvantage of any fibrous yarn packing is that fibers do not totally seal fluids - they restrict flow. To provide a more effective seal, the braided carbon/graphite fiber packings are impregnated with "blocking agents," which refers to any compatible viscous lubricant that can be used to fill the voids and affect a seal between the fibers.

Blocking Agents

Historically, typical blocking agents were greases, oils and waxes. They were used to provide the necessary sealing characteristics in asbestos, cotton and flax fiber packings. Today, the most common blocking agent for carbon/graphite fiber packings is a colloidal form of PTFE. The carbon/graphite fibers are treated with the PTFE dispersant which effectively seals the voids between the fibers. It is typical to find as much as 16 percent to 25 percent PTFE in some carbon/graphite fiber packings.

PTFE is an effective blocking agent except for two pitfalls. First, when used on high-speed rotating shafts, the PTFE tends to sinter or form a hard plastic-like inner region of the packing ring where it makes contact with the shaft. This makes it difficult to impossible for gland adjustments, thereby requiring eventual replacement. Secondly, it can be responsible for acceleration of serious pitting-corrosion in pump shafts as well as valves stems.

This pitting and corrosion is most prevalent when temperatures exceed 700-deg F, where PTFE begins to decompose. Decomposition generates hydrogen fluoride (HF) gas. HF gas, when exposed to moisture, forms very corrosive hydrofluoric acid. Thus, carbon/graphite fiber packings containing PTFE blocking agents should not be applied at temperatures above the maximum recommended for PTFE.

To offset these problems other blocking agents, such as colloidal graphite, have been developed and used. Most of these do not contain any significant quantities of halogen compounds so have lesser tendency to cause pitting or stress corrosion cracking.

Conclusion

Graphite and carbon fiber braided packings have proven to be effective solutions to many common sealing applications. For the proper selection and installation of these packings in any application, it is always best to consult your packing manufacturer.

Effective Mechanical Sealing Solutions for Industrial Applications

Excellence in Sealing Solutions: Mechanical Seal Manufacturer and Gland Packing Seal Types

In the world of fluid handling and industrial machinery, the importance of effective sealing solutions cannot be overstated. Whether it's to prevent leakage, protect sensitive equipment, or ensure operational efficiency, mechanical seals and gland packing seals play a pivotal role. In this article, we'll explore the world of mechanical seal manufacturing, delve into the different types of gland packing seals, and also touch upon the significance of single cartridge mechanical seals. Additionally, we'll shed light on the collaboration between mechanical seal manufacturers and OEM pumps manufacturers.

Mechanical Seal Manufacturer: Precision in Every Seal

A mechanical seal is a critical component in pumps, compressors, and various other machinery that handle liquids or gases. It serves the crucial function of preventing leakage and maintaining the integrity of the process. Mechanical seal manufacturer are the unsung heroes behind these tiny yet essential devices.

These manufacturers are tasked with producing seals that can withstand high pressures, temperatures, and corrosive environments. They employ cutting-edge technology and materials to ensure that their seals meet the highest standards of performance and reliability. The seal's design, material composition, and manufacturing process are all meticulously engineered to match the specific requirements of their intended applications.

Gland Packing Seal Types: Versatility and Dependability

Gland packing seals are another sealing solution commonly used in various industrial settings. Unlike mechanical seals, which are closed systems, gland packing seals consist of braided or molded packing material that is compressed within a stuffing box or gland. This creates a seal by preventing the escape of fluid along a rotating or reciprocating shaft.

There are several types of gland packing seals available, each suited to different applications:

Braided Packing: This is the most common type of gland packing, made from materials like graphite, PTFE, or aramid fibers. It is flexible, easy to install, and effective in sealing a wide range of fluids.

Molded Packing: These seals are pre-formed and shaped to fit specific applications. They offer excellent dimensional stability and are ideal for high-performance applications.

Inconel Wire Reinforced Packing: This type of packing includes Inconel wire reinforcement to enhance its strength and stability, making it suitable for high-pressure and high-temperature applications.

Carbon Packing: Carbon packing is designed for extreme conditions, including high-speed rotary equipment and aggressive chemicals.

Single Cartridge Mechanical Seal: Simplifying Maintenance

Single cartridge mechanical seals are a specialized variation of mechanical seals that offer ease of installation and maintenance. Unlike traditional mechanical seals, which require intricate assembly and precise alignment, single cartridge seals are pre-assembled in a self-contained unit.

These seals are especially beneficial in applications where minimizing downtime and ensuring quick and hassle-free replacements are essential. They reduce the risk of incorrect installation and are often used in critical processes where any seal failure can lead to costly consequences.

Collaboration with OEM Pumps Manufacturers

Mechanical seal manufacturers frequently collaborate with OEM (Original Equipment Manufacturer) pumps manufacturers to provide integrated solutions for various industries. OEMs rely on mechanical seal manufacturers to supply seals that perfectly match their pump designs and specifications.

This collaboration ensures that pumps are equipped with seals optimized for their intended use, enhancing overall performance, longevity, and efficiency. Additionally, it simplifies the procurement process for end-users, as they can trust that the seals supplied with the OEM pumps are of the highest quality and compatibility.

In conclusion, the world of mechanical seal manufacturing and gland packing seal types is a testament to engineering precision and innovation. These components may be small, but their impact on industrial processes is enormous. Whether you're seeking a reliable sealing solution for your machinery or collaborating with OEM pumps manufacturer choosing the right partner in mechanical seal manufacturing is a critical step toward ensuring the success and longevity of your operations.
