MSS SP 83 threaded union is used to connect two pipes and the ends will be machined to NPT or BSP that match external end threads of pipe.The ANSI/ASME B16.1threaded union is similar to the coupling and can be flexibly disassembled when it needs to be repaired or replaced. The large demand material is carbon steel A105 and stainless steel 304 & 316. We manufacture forged steel union according to MSS SP-83.
It is commonly conforming to ASTM A105N /SA105N, N means Normalized. This material is generally used for manufacturing forging process and high pressure system.
