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 belong to forged fittings.ASME B16.11 is presents forged pipe fittings in American Standard.

 

Threaded Types:

NPT  PT  BSPP  BSPT  PF

 

Application:

Forged Threaded Fittings Union are designed for wide use in different industries like oil refineries, chemical processing, petrochemical and many other industries.

 

Threaded Union VS Threaded coupling 

The basic difference between couplings and unions in use is that couplings connect pipes to pipes or pipes to bends.Unions are used to connect and disassemble part of the piping system for maintenance or replacement.
