Socket weld full coupling · forged A105 · ASME B16.11 · UAE stock
A short forged sleeve with a socket at each end that joins two lengths of small-bore pipe in a straight line. It is the simplest socket weld fitting and one of the most used, also serving as a weld-on nozzle when cut.

A socket weld coupling is a forged or bar-machined sleeve with a socket bored from each end and a small internal stop between them. Both pipes are inserted, backed off for the expansion gap and fillet welded. It is used to extend pipe runs, to repair a cut line or to join a pipe to a fitting where a butt weld would be difficult to make in small sizes.
Hamza Fasteners keeps class 3000 A105 socket weld couplings from 1/8 to 4 inch and can supply class 6000 for heavy wall lines. Reducing couplings and half couplings complete the family. Contractors use them on instrument tubing tie-ins, compressed air and nitrogen headers, lube oil systems and plant utility piping across the UAE.
