2" Class 3000 Socket Weld Coupling ASTM A182 F51 ASME B16.11

General Details

Socket weld coupling is a combination of provision that can join two pipes or tubes together with a socket at one end or both ends.

Socket Weld Fittings also cover  90 degree elbow, 45 degree elbow, tee, cross, union, cap, lateral. Duplex stainless steel pipe fittings is our hot sale product, especially Class 3000 Stainless Steel Socket Weld Fittings in material grade 304 & 316.

They are used for their good mechanical properties in the as-cast (and therefore as-welded condition) and their excellent corrosion resistance properties (particularly to stress corrosion cracking).

B16.11 Full Coupling Weight Chart

The weight of coupling is available in both socket weld and threaded. The size is from NPS 1/8″ to 4″ and pressure ratings cover Class 3000# and 6000#. So we can call them as high pressure pipe fittings.
