Socket Weld Coupling

We are manufacturer of Socket Welding Coupling and supplies full coupling,half coupling in kinds of materials such as carbon steel, stainless steel, alloy steel.

We have offered clients couplings in ASME, BS3799 standard dimensions and materials, as well as in some special dimensions and materials according to requirements. The abundant produce experience allows us to supply you high quality products in the shortest time.

Zizi offers socket weld forged fittings including 90 degree and 45 degree elbow, equal tee and reducing tee, coupling, union, cap and sockolet.

Types of Coupling

Full Coupling: The basic coupling type that is used to joint two pipes by socket welding. The two ends of full coupling is of equal size and connection way

Half Coupling: Only one end is socket welding.

Reducing Coupling: It is a full coupling which has two ends in different diameters.

Socket Weld Coupling Dimensions

Both SW full coupling and half coupling have the same dimension ranges.

Size: 1/8”, 1/4″, 3/8″, 1/2″, 1/4″, 1″, 1 1/4″, 1 1/2″, 2″, 2 1/2″, 3″, 4″

Pressure: Class 3000, Class 6000 and Class 9000
