high pressure fittings

High Pressure Socket Welding Union

High pressure fittings include forge fabricated carbon and stainless alloyed fittings, with pipe thread and welding joints, and with pressure to 2.000, 3.000, 6.000 and 9.000 LBs, designed in compliance with ASME B16.11 and MSS-SP.

Socket welding unions include forged carbon-alloy and stainless steel made Union, sizing NPS 1/8~3in to MSS-SP-83-2001. They are in general made from raw round bar of diameter 19~85mm.
