  • Rated for 3000 psi at 72 °F for high-pressure systems
  • Black forged steel construction resists corrosion and mechanical stress
  • Socket-weld connection creates a permanent, leak-tight joint
  • Meets ANSI B1.20.1, ASME B16.11 and ASTM A105 standards
  • Class 3000 union fits 1-1/4 in pipe for industrial plumbing

Union for socket-weld piping systems

This black forged steel union is built to ANSI B1.20.1, ASME B16.11 and SA105 and ASTM A105 standards. It carries a Class 3000 rating with a maximum pressure of 3000 psi at 72 degrees F. The socket-weld connection suits 1-1/4 inch pipe in industrial plumbing installations.

Socket-weld installation requires pipe preparation

The socket-weld end demands accurate pipe cutting, deburring and alignment before welding. Improper fit-up or insufficient penetration creates leak paths that are difficult to remedy after the system is pressurised. A qualified welder following the referenced ASME and ASTM codes reduces the risk of joint failure.

Suits high-pressure steam, oil or gas lines

This union serves plants and contractors needing a demountable joint rated for 3000 psi service. It is not intended for low-pressure water systems where a threaded or compression fitting would be simpler and more economical. Buyers needing a different pipe size, pressure class or connection type must select an alternative fitting.

What components are included and what must I supply for installation?

The box contains the black forged-steel union only; you must provide matching 1-1/4 in pipe, socket-weld consumables and any thread sealant required by your piping code.

Which class rating should I select for a 3000 psi system at 72 °F?

Choose the Class 3000 version listed — it is rated for 3000 psi at 72 °F and complies with ANSI B 1.20.1, ASME B 16.11 and SA105/ASTM A105 standards.
