- Meets ANSI B1.20.1 and ASME B16.11 standards for code compliance
- ASTM A105 material rating ensures reliable mechanical strength
Black forged steel socket-weld union
This Value Brand union joins two 3/4 in pipes using a socket-weld connection. The fitting is manufactured from black forged steel to ANSI B1.20.1, ASME B16.11 and ASTM A105 standards. It is rated for Class 3000 service in industrial piping systems. Buyers needing threaded or flanged connections cannot use this fitting.
Class 3000 pressure rating and temperature limit
The union withstands a maximum pressure of 3000 psi at 72 degrees Fahrenheit. This rating provides headroom for high-pressure hydraulic or steam lines within the stated temperature. Pressure capacity decreases as operating temperature rises above the reference point. Systems requiring higher pressure classes or elevated temperature ratings need a different fitting class.
Socket-weld interface and material constraints
The socket-weld design demands precise pipe alignment and skilled welding for a leak-free joint. Once welded, the union cannot be disassembled without cutting the pipe. Black forged steel offers strength but lacks the corrosion resistance of stainless alloys in aggressive chemical environments. Installations requiring frequent maintenance or chemical compatibility must select an alternative connection type.

Questions about this item
Will this 3/4 in Class 3000 socket-weld union mate with pipe built to ANSI B 1.20.1 threads?
The union uses a socket-weld connection, not threaded ends, so it joins pipe by welding into the socket rather than mating with ANSI B 1.20.1 threads.
How can I confirm the forged steel union is holding its 3000 psi rating at 72 Degrees F after installation?
Pressurise the system to the design pressure and inspect the socket-weld joints for leaks; a sound weld that shows no weeping at test pressure indicates the Class 3000 rating is being met.
Does the box contain only the union or are gaskets and bolts included for the socket-weld connection?
The union is a single forged steel piece with no separate gaskets or bolts; the socket-weld joint is completed by welding the pipe directly into the fitting ends.
