How to get high quality pipe coupling?

What is a pipe coupling?

Pipe coupling connect two pipes or tubes together of equal or differing sizes . Pipe coupling mainly aims to solve the existing couplings easily generated due to fatigue fracture stress concentration problems.
Pipe coupling structure is: pipe ends with the inner wall of the coupling connected to tapered threads, couplings and tubing ends of the body with the same thread pitch flat with threaded connect. A single taper threaded connection with relief tubing outer thread root stress concentration characteristics, not easy to produce fatigue fracture, connecting effect. Effectively prevent oil well pipeline string broken off accidents.

A pipe coupling is any fitting or device used to join two or more pipes in such a way that continuity is maintained between them. The body of a pipe coupling is typically made of the same or similar materials as those used to construct the pipes it joins. They may be rigid or flexible depending on the amount of movement the pipe is subjected to and may per permanent or removable fixtures. A pipe coupling can be stepped or reduced in internal diameter to accept pipes of different sizes, be T or cross shaped to join more than two pipes, or angled to form bends. Pipe couplings may also include peripheral features or equipment such as inspection openings, flow meters, or valves.

Most pipe installations require that several lengths of pipe be joined together or cut to facilitate changes in direction and crossing of obstacles. This requires a fairly quick method of connecting the sections while maintaining the integrity of the pipes in the process. These couplings may be permanent by nature or, if possible disassembly is desirable, of a removable design. Permanent pipe couplings generally make use of soldering or brazing in the case of steel or copper pipes or adhesives in the case of PVC pipes. These permanent joints, if correctly installed, offer excellent rigidity and sealing characteristics where no future changes in the piping are foreseen.

Removable pipe couplings are most often of a threaded design which allows them to be screwed onto the pipes to be joined. The most simple of these is a basic pipe section slightly larger than the pipes to be joined and cut with an internal thread. The ends of the pipes are also threaded, and the coupling is simply sealed with hemp or sealing tape and screwed onto both pipes. More complex removable pipe couplings are of a two-part design where one part is attached to each pipe and then screwed together to complete the joint. These types of couplings are often used on high pressure copper gas pipes and flexible hydraulic or pneumatic hoses.

pipe coupling is also often used to facilitate changes of pipe routing, crossing of obstacles, and penetration of walls. These couplings are typically elbow or U shaped but may include several variants featuring different angles of deflection. Step-down or reduction pipe couplings featuring different end diameters are used to join pipes of dissimilar sizes. Adaptor fitting may also be used to join pipes of different materials and feature separate end fittings suitable for both materials. Where more than two pipes are to be joined Y, T, or cross shaped couplings are common methods of achieving the joints.

Pipe couplings may also include other features such as inspection or maintenance access points. These are typically screw-on caps that allow for visual inspections or the insertion of rods used to remove blockages. Flow meters and other analytical attachments are frequently built into a pipe coupling to ease installation. Pipe couplings may also include mechanisms such as shut-off and pressure release valves.

What is threaded full coupling?

A threaded full coupling which means a steel pipe coupling has two ends both threaded. It could be a coupling with the thread only on the two ends, also could be a coupling with thread all over the length, they are all called full pipe coupling.

Sometimes the two ends thread may be different, one end is BSP and another end is NPT, then it is like a adaptor for pipes which have different type of thread ends. When installing it, the workers should check the direction for correct match .

What is threaded half coupling?

A threaded half coupling means a steel coupling which only has one thread end, another end of the coupling should be butt welding end. The thread end could be NPT or BSP standard thread. The butt welding end could be a plain end or a bevel end. it could be the connection between a pipe of male thread end and a pipe of no thread end.

Coupling fittings are used for fluid conduits in which each end portion of two tubes to be connected is provided with a swaged-on adapter carrying the necessary means to connect or disconnect the tubes without disturbing the swaged-on adapter.

Our range of coupling fittings are available in aluminium, steel and bronze.

Pipe couplings are highly demanded in the pipe fitting market. Pipe couplings are fittings that help to extend or terminate pipe runs. These fittings are also used to change pipe size. Couplings extend a run by joining two lengths of pipe. They are known as reduced coupling if they are used to connect pipes of different sizes. Couplings are also known as repair couplings. These couplings are without stops or ridges and they can be fixed anywhere along the pipe length for preventing leak of any kind.
