What are the Types and Uses of Coupling Pipe ?

A  coupling pipe , also known as a coupler, is a device that connects pipe sections while maintaining the pipes’ integrity. For the piping and plumbing sector, it is a very useful pipe fitting. To facilitate changes in direction and crossing of obstacles, most pipe installations require many sections of pipe to be connected or cut. A pipe coupling is a pipe or tube that is only a few inches long and at one or both ends, it features socket or female pipe threads that connect two pipes or tubes of the same or different sizes to form a long pipe run.

TYPES OF  COUPLING PIPE

Full Coupling Pipe

A full coupling is used to join two pipes or a pipe to a swage or a nipple and is available with threaded or socket ends for connecting tiny bore pipes.

When the pipe standard requires socket weld, a socket weld full coupling is utilised to link small-bore plain end pipes. Small-bore pipes with threaded ends are joined with a threaded complete coupling; when the two ends of coupling are different for example, one BSP threaded and the other NPT threaded, it’s called an adapter.

Half-coupling Pipe

A half coupling can be threaded or socketed on one side and is used to branch small-bore pipe from a vessel or large-bore pipe. To make a branch connection, a socket weld half coupling can be directly welded to a large bore pipe and is utilised to branch off a large bore pipe into a small bore pipe when the pipe spec calls for a socket weld in the small bore size.

Reducing Coupling Pipe

Reducing couplings pipe  are used to join pipes with different diameters; On each side of a reducing coupling, there are two distinct diameters of threads. When small process feeder lines are connected to large supply circuits or small diameter fittings are fitted, reducing couplings are frequently employed.

These couplers have a simplistic, stepped down design and screw onto the two lengths of pipe like a normal pipe junction. While welded reducing couplers are similar to threaded reducing couplers, but they don’t have threads.

Compression Coupling

A compression coupling connects two perfectly aligned pipes by inserting a slotted tapered sleeve over the junction and dragging two flanges over the sleeve to centre the pipes and provide sufficient contact pressure.

USES OF PIPE COUPLINGS

As the range of pipe applications expands, its strength, versatility, high flow rates, and chemical tolerance make it excellent for transporting or converting liquids, steam, solids, and air from one stage to the next. Coupler pipes are used to easily join two pipes and have flexible joints that do not require the use of any additional equipment, nevertheless offering secure, durable seals.

Seal Excel pipe couplings are utilised in pipe networks on ships and offshore, for firefighting, heating, air supply/removal, and sea/freshwater storage. So that’s not the end of it; they are commonly used in plant maintenance, power plants, water and gas delivery facilities, manufacturing, structural engineering, architecture, and other equipment.
