Socket welding coupling ASTM A105/105N NPS1/8″-4″
Concept of SW Couplings
The types of socketweld coupling include double-socket pipe clamps and single-socket pipe clamps. Among them, double-socket weld coupling can be divided into equal diameter and different diameters, and double-socket weld coupling with diff Diameters can also be divided into concentric and eccentric.
Socket pipe fittings are mainly formed from round steel or steel ingot die forging blanks, and then processed by lathes, which are a kind of high-pressure elbow pipe fittings.
