Socket Weld Coupling-Full Coupling,Half Coupling

Haihao Group manufacture & supply & export pipe coupling in high quality.A pipe coupling is a very short length of pipe or tube which used in piping system,and it allows two pipes or tubes of equal or different size to be joined together.According to the types of end connection,it can be divided into socket weld coupling and threaded coupling.Socket weld coupling means the coupling with socket at one or both ends.Threaded coupling means the coupling has threads at one or both ends.

Types of socket weld couplings:

• Socket weld full coupling
• Socket weld half coupling

ASTM A182 F316L Socket Weld Full Couplings

What is a socket weld full coupling?

Socket weld full coupling means the coupling has two ends both socket weld.It is used to connect small caliber pipes and connect pipe to pipe or pipe to swage or nipple.Socket weld full coupling can be divided into equal diameter or reducing diameter.

Socket weld full reducing coupling is used to connect pipes of dissimilar diameters.A reducing coupling has two different sizes of socket on each side.Reducing couplings are typically used where small process feeder lines are joined into large supply circuits or where small diameter fittings are installed.Reducing couplings will normally feature a simple, stepped down profile and socket weld onto the two lengths of pipe in the same way a standard pipe joint does.

Stainless Steel Socket Weld Half Coupling

What is a socket weld half coupling?

Socket weld half coupling means the coupling only has one socket end,another end of the coupling should be butt welding end.The butt welding end can be a plain end or a bevel end.A socket weld half coupling can be directly welded to large bore pipe, to make a branch connection. It is used to take a small bore pipe branch-off from a large bore pipe where the pipe spec requirement is socket weld in small bore size.
