What is a Threaded/Socket Weld Full Coupling?
A Threaded/Socket Weld Full Coupling is a forged pipe fitting used to connect two pieces of pipe or a pipe to a fitting in a straight line. Unlike a half coupling, it features internal connections on both ends and is used in permanent or semi-permanent piping setups.
Threaded Full Coupling: Features internal threads on both ends for quick, leak-tight connections without welding. Ideal for lower-pressure systems or applications where maintenance access is required.
Socket Weld Full Coupling: Designed with socket ends that allow precise pipe insertion and welding, creating a strong, pressure-tight joint. Preferred for high-pressure, high-temperature pipelines.
These couplings are essential for extending pipe runs, changing sizes, or joining pipes in critical flow systems while maintaining structural integrity.
