The ASME B16.11 Stainless Steel 3000# Socket Weld Union is a high-pressure three-piece fitting designed for quick assembly and disassembly of piping sections. Forged from grades like 316L or 316Ti, it features a ground joint for a metal-to-metal seal, offering superior leak resistance without gaskets. The socket ends facilitate easy pipe alignment and welding. Rated for 3000 PSI, it is essential in process lines requiring frequent maintenance or component replacement in corrosive environments.
