How Many Types For the API Couplings?

There are several types covered in API 5CT standard for coupling specifications, classified in regular couplings, special clearance couplings, combination couplings, reducing couplings, seal ring couplings, and special bevel tubing regular couplings.

Regular couplings

Regular couplings diameters complied with API 5CT Tables C.32 to C.35 or Tables E.32 to E.35. Coupling bearing contact face inside and outside edges shall be rounded or broken, but shall not significantly reduce the width of the bearing face (dimension b), since less thickness will not be safe to support the pipe weight. The ends of couplings shall be faced exactly at right angles to the axis.

Special clearance couplings

In the case specified in the contract, special-clearance (reduced outside diameter Wc) couplings for buttress (BTC connection) casing and external upset (EUE connection) tubing shall be furnished. Unless otherwise specified, special-clearance external upset tubing couplings shall have a special bevel on both ends. The inside and outside edges of the bearing face shall be rounded or beveled. The ends (or root face when beveled) of couplings shall be faced at right angles to the axis.

Special-clearance coupling dimensions and tolerances shall comply with as given in Tables C.33 and C.35 or Tables E.33 and E.35 and as shown in Figures D.3 and D.5. Color identification sees clause 11.

Combination couplings

Combination couplings with different types of the thread of the same specified size shall be furnished when specified on the contract. The minimum length and minimum OD of this coupling shall be sufficient to work with the specified size specified threads.

Reducing couplings

Reducing coupling is also a kind of pup joint, used to connect two pipes of different diameters with the same or different types of thread on the two ends. Same with combination coupling, minimum length and minimum diameter of reducing couplings shall be sufficient to support the specified size and threads.

Seal-ring couplings

Sealing-ring couplings conforming to the requirements shall be furnished when specified in the PO. Grooves may be cut before or after threading at the manufacture’s option. Grooves and threads shall be free of fins, wickers, and ribbons that are loose or can become loose and fold into the thread dorm. Couplings shall be inspected after the final machining of the groove.

Special clearance coupling

When specified in the order, special-clearance (reduced outside diameter) couplings for buttress casing and external upset tubing shall be furnished.

Combination coupling

Reducing coupling are used to connect two pipes of different diameter with the same or different types of thread on the two ends, and shall be furnished when specified on the agreements. The minimum length and minimum diameter of reducing couplings shall be sufficient to accommodate the specified size and type of threads.

ss pipe weight chart

The term ERW in stainless steel vocabulary generally refers to a specific type of welding process. This kind of welding is one which involves both spot as well as seam welding. Typically, seam welding is a process which is commonly used during the manufacture of round, square or rectangular steel tubes.  On the other hand, the procedure to produce ERW stainless steel pipe dimensions would involve a flat stainless steel plate or sheet which is first rolled by being cold formed into the shape of a cylinder to become a pipe; followed by which, the cylindrical pipe is then welded using Electric Resistance Welding process longitudinally. Hence, the name ERW pipes. Usually, the ERWstainless steel pipe weight chart is used in the manufacture of pipes with a high diameter.ss pipe weight

Both continuous welded stainless steel pipe dimensions as well as electric resistance welded pipe can be manufactured by shaping rolls of coiled steel into cylindrical forms and welding along the longitudinal seams of the pipes.There are several ways for the electric current which is to be used for welding the rolled strip or rolled pipe. One of these methods including a revolving copper disc, which is a fixed alloy Cu or copper contacts along with induction coils. Using this method ensures that the temperature of the steel edge has risen to about 2600 deg F, which is required for effective welding. The rolling process for the ERW stainless steel pipe exerts so much pressure that it tends to create a metal welded seam on the outside as well as on the inside of the pipe. However, these weld seams, which occur during this stage could be then removed during the finishing process of these stainless pipe sizes schedules. Following this treatment the ERW welded pipe will then be heat treated, inspected along with being hydro tested. Find out more about the ss pipe size chart here.

Usually, the ERW ss pipe sizes in mm is available in many of the following specs ASTM A53, A135, A252, A500, A795, API 5L and API 5CT. Although the most typically used specification for the construction of ERW specs would be both the A53 and the API 5L.ss pipe weight

The Protection of OCTG

Oil Country Tubular Goods (OCTG) refer to collections of rolled metal products, or pipes and the accessories that are included in their manufacturing and processes. These items include, but are not limited to, thread protectors, stabbing guides, pipe chocks, bumper rings along with drill, casing and tubing pipes – the most critical element of OCTG. Pipe products are considered OCTG because of the specifications of each pipe with concerns to acceptable loading conditions, what they are capable of transferring, their strength and composition.

Drill pipes are heavy duty, strong and critical in any OCTG endeavor. The heavy, often seamless tubes are used in the rotation of the drill bit and drilling fluid where they can be joined using tool joints. When in use, pipes undergo axial tension along with high torque and internal pressure from the pipe’s own dead weight when in use, exhaust of drilling fluid, and the actual drilling and turning of the bit. A different type of pipe used to line the borehole (the actual hole dug in the ground) is referred to as a “casing pipe”. It too, undergoes axial tension just like the drill pipe, but it differs in that it has to withstand addition pressure from the rock and sediment that it has bored into, along with pressure from the oil itself. It is also extremely heavy duty.

An additional pipe will go inside of the casing pipe, and will eventually become the pipe through which the oil will travel. This pipe is referred to as a “tubing pipe.” Tubing pipes are usually produced in segments of about nine meters (or approximately 30 feet), with threaded connectors at each end. Tubing pipes are the most simplistic of the OCTG pipe family. The connectors at the end of tubing pipes can and should be protected by drill pipe protectors during storage and transportation. This will also protect against corrosion that can happen. When tons of oil is being pumped through tubing pipes, it is imperative that there are no damages which could compromise the integrity of the pipe threading.

Oil Casing Pipe

Oil Casing Pipes are available in various wall thicknesses and diameters. Oil Casing Pipes are used for the transportation of crude oil and natural gas from an oil or gas layer to the surface after drilling is complete. It is made to withstand the pressure generated from the extraction process. Oil casing pipes are manufactured in the same way as casing, except that an additional process known as "upsetting" is applied to thicken the pipes.

China's Manufacturing Industry Cannot be Easily Speaking Out of“Turn Off”

Real economy problem widely concerned recently, "heavy light virtual reality", "take off the real to virtual" tendency, even some people said that our country has completed industrialization, manufacturing should quit the historical stage. As a SSAW, 3 PE anticorrosive coating steel pipe, large diameter DSAW stee pipe and other products production services, Shinestar group have been much concerned about the development of the real economy. Shinestar steel research institute believes that manufacturing never speaking out of “turn off".

Starting in the 1980 s, the United States, Britain, France and other countries dominated "de-industrialisation" was once very modern, even become a prominent phenomenon of globalization. As a result, it is caused of the international financial crisis of 2008. Facing financial disaster from these mistakes and almost all developed countries recognize that manufacturing is the founding this, can not be replaced, can't quit, must restore manufacturing, will be "de-industrialisation" reverse "industrialization". Manufacturing in the developed world can't, can't go back, in our country,  can't refund,  can't go!

Our country as a developing country, industrialization process is still very long, industrialized task is still arduous, manufacturing not speaking out of “turn off". For now, the real economy encountered some difficulties, and economic new characteristics under the new normal inner link, must take the initiative to adapt to the new normal; And "real to virtual" off "display" and "light weight virtual to real" also have a contact, must be corrected in a timely manner. At the same time, also has a lot to do with industrial transformation and upgrading.

Development of industrial manufacturing as the core of the real economy, is by no means to get low-end manufacturing industry, but to drive by eliminating backward production capacity and innovation, realize the traditional enterprises and upgrade traditional industries; By supply side structural reform, promote upgrading of the industrial structure; Through the development of strategic emerging industry development is more adapt to the market demand of new technologies, new forms and new patterns, etc., to promote "made in China" to a "high-end manufacturing in China"

The main manufacturing is the revitalization of the real economy. In 2017, the central economic work deployment, has clearly put forward the revitalization of a major task of the real economy. How to eliminate misunderstanding, correct "light weight virtual to real" "take off the real to virtual" tendency, and so on, are we are faced with the important task.

Shinestar group will also conform to the trend, eliminate backward production capacity, promote upgrading of the industrial structure, strive to produce high quality carbon seamless steel pipe, boiler tube, API?5CT?well?casing,?API 5CT?Tubing,?API?5DP?drill?pipe,?pup?joint,?line?pipe, welded?steel?pipe, ERW steel pipe, LSAW steel pipe, SSAW steel pipe, OCTG, coating pipe and other products, so as to improve enterprise competitiveness, the revitalization of the real economy, strive to hand over a satisfactory answer.
