Forged Steel Fittings

MSS SP 83 is the specification for Class 3000 socket weld union which cover size tolerance, marking, material in carbon steel, alloy & stainless steel.

1 1/2 inch Socket Weld Union, ASTM A182 F53 Duplex Steel Pipe Fittings, ASME B16.11 Forged Steel Fittings are in hot sale with attractive price and quality.

We produces high pressure socket weld fittings for connecting pipes or other fittings together in many industrial processes that no leakage can be permitted. Socket welding provides a strong and efficiency joint to support this function. And limited by its manufacturer standard, it is more suitable for small diameters application below 4 inch.

Class 6000 Unions in duplex steel A182 F53 have excellent corrosion resistance and high strength so that they are high demanded in chemical industries such as pulp and paper mills. Duplex steel fittings are solid and lasting, even in the most demanding circumstances, they can perform well.
