Socket Weld Fittings

Socket weld fitting is SW fittings, a high pressure forged pipe fittings what is applied to various piping systems. With a step on the gallery, a pipe is inserted into the recessed area to welding and installing. In contrast to buttweld fittings, socket-weld fittings are generally small diameter but with high pressure rate working. Socket-welded Joints construction is a good choice wherever the benefits of high leakage integrity and great structural strength are important design considerations.

Kaysuns provide full range of socket-weld fittings in standard ASME B16.11, BS3799, JIS2316 etc., the materials such stainless steel, duplex steel, carbon steel, low temperature alloy, nickel base alloy are available.
