Introduction of ASME B16.11 Socket Weld Coupling
Half Socket Weld Coupling
Full Socket Weld Coupling
Socket weld (SW) is a connection way used for pipes and fittings , which include reducers, tees, elbows and so on. ASME B16.11 socket weld coupling is a full coupling or a half coupling using socket weld as connection, despite socket weld, there are also threaded as a commonly used connection way for couplings. ASME B16.11 socket weld couplings are divided into Class 3000, 6000, and 9000 three types basing on their pressure ratings.
Manufacturing Standard of Socket Weld Couplings
All different kinds of couplings apply to the same standard in each country, in American standard they should follow the manufacturing standard ASME B16.11. In 1992, American government compiled ASME series standard basing on the need and requirement from industry, including pressure ratings, dimensions, tolerances, markings and material requests for ASME B16.11 socket weld coupling.
Size and Pressure Range
Not only ASME B16.11 socket weld coupling, usually all kinds of forged steel fittings, no matter they are socket weld or threaded, their size usually below 4 inches.
