We are the manufacture who has been applied by ISO. And the high pressure steel pipe fittings are our main products. ASME B16.11 is the standard for Socked Weld Fittings Coupling.
ASME B16.11 is the standard contains ratings, dimensions, tolerances, marking and material requirements for forged fittings, both socket-welding and threaded. Threaded fittings are available in pressure ratings Class 2000, 3000, and 6000;
Socket welding fittings are available in pressure ratings Class 3000, 6000, and 9000.
Generally, both fittings size range is 1/8″- 4″or DN6-DN100.
There are various types of ASME B16.11 socket-welding fittings, such as Elbow, Cross, Tee, Coupling, Half Coupling, Boss, Cap, Union and Sockolet; while ASME B16.11 threaded fittings can be furnished in product forms of Elbow, Cross, Tee, Coupling, Half Coupling, Boss, Cap, plug and bushing.
A Socket Weld Tube Fittings is a pipe attachment detail in which a pipe is inserted into a recessed area of a Valve, fitting or flange. Once correctly inserted, fillet type sealing welds are applied to join the pipe to the fitting.
Different from buttweld fittings, Socket Weld fittings are mainly used for small pipe diameters (Small Bore Piping); generally, for piping whose nominal diameter is NPS 2 or smaller.
Socket Weld Coupling material can be divided into carbon steel, alloy steel and stainless-steel.
Socket welding Tube fittings are available in pressure ratings Class 3000, 6000, and 9000.
There are various types of socket-welding Tube fittings, such as Elbow, Cross, Tee, Coupling, Half Coupling, Boss, Cap, Union and Sockolet
