They are are produced to several ASTM standards and are manufactured in accordance with ASME B16.11. The B16.11 standard covers pressure-temperature ratings, 

ASME B16.11 Socket Weld Pipe Fittings Dimensions Dimensions are in millimeters unless otherwise indicated. Wall thickness (t) should be nominative by client. Outlet dimension (M) for NPS and bigger is usually recommended however not needed. ASME B16.11 Socket Weld Pipe Fittings Weight Chart Manufacturing Process of Socket Weld Forged Fittings

In summary, socket weld fittings are available in forged carbon steel, stainless steel, and nickel alloys. They are made as per ASME B16.11. Socket weld fitting comes in a pressure rating of 3000 pound, 6000 pound, 9000 pound. Loosely, they are related.

ASME Standard B16.11 provides dimensions and requirements for Socket weld Fittings of sizes 1/8″ and upto 4″. But in most piping material specifications for
