Half Couplings
|
|
Description:
Half coupling is a very short length of pipe or tube which is used for small bore branching from a vessel or large bore pipe. It allows two pipes or tubes to be connected with a socket or thread-typed end. It has a socket or thread end at only one side. Another end will be welded or fastened to the piping. Half coupling is made of SS316 or A105 materials. There are two working pressure for half couplings which are 3000# and 6000#. Features:

Threaded End Half Coupling
What is half coupling?
Half coupling is a very short length of pipe or tube which is used for small bore branching from a vessel or large bore pipe. It allows two pipes or tubes to be connected with a socket or thread-typed end. It has a socket or thread end at only one side. Another end will be welded or fastened to the piping. Half coupling is made of SS316 or A105 materials. There are two working pressure for half couplings which are 3000# and 6000#.
A socket weld half coupling can be directly welded to a large bore pipe, making a branch connection. Socket weld half couplings are mainly used for small bore piping (small pipe diameters). It is applied to branch off a large bore pipe into a small bore pipe when the pipe spec requires a socket weld in the small bore size. Moreover, a threaded half coupling only equips one thread end while the other end of the coupling is a butt welding end with either a plain end or a bevel end.
What is the function of half couplings?
During the piping or plumbing installation, it is often necessary to connect several lengths of pipe to facilitate changes in directions or crossing of obstacles. Thus, this requires a relatively rapid way of connecting the pipe sections while retaining the comprehensiveness of the pipes in the process. There are variety functions of a half coupling as following:
What is the difference between full and half coupling?
Generally, full coupling is used to connect small bore pipes. It is applied to connect pipe to pipe or pipe to swage. The full coupling has both ends of threaded or socket welded connection and greater size compared to a half coupling.
Half coupling is used for small bore branching from a vessel or large bore pipe. It is only threaded or socket welded at one end, and the other end is welded type. Thus, it can only be connected in one direction. Half coupling has smaller size than a full coupling.
What is the difference between a coupling and a union?
Similar to couplings, a union also connects or joins two or more pipes during piping installation. However, a coupling is normally used for permanent joining by requiring solvent welding, soldering, or rotation (for threaded couplings).
In contrast, a union is a type of very compact flange connector. It comprises three components which are a nut, a female end and a male end. When the female and male ends are connected, the nut seals the joint by pressing the two ends tightly together. A union allows easy connection and disconnection of a part of piping systems. It eases the assembly process for fixing, maintenance or replacement in the future.
Industry application of Half Couplings:
A stainless steel threaded half coupling is applied in several industries such as printing machinery, automated plants, textile machinery, and other varied industries. Besides, half-couplings are also widely used in the aerospace industry. They serve as connectors to pressurized fuel piping. Furthermore, half couplings are used intensively on fire protection systems, air and water lines and many different lower pressure process lines.

Thus, this requires a relatively rapid way of connecting the pipe sections while retaining the comprehensiveness of the pipes in the process. There are variety functions of a half coupling as following:
- It extends or terminates pipe runs.
- It can be used to change pipe size.
- It connects two pipes together.
- It helps to repair a broken or leaking pipe.
