The threaded pipe union is similar to the coupling and can be flexibly disassembled when it needs to be repaired or replaced. The reducing threaded union is easy to disconnect and link, and can be operated multiple times.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 threaded pipe 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.
