4" FIG 602 Hammer Union – Butt Weld – Standard Service

The 4" FIG 602 Hammer Union – Butt Weld is a heavy-duty high-pressure connection designed for demanding drilling, cementing, pressure pumping and well-service applications.

Featuring butt-weld ends, the union is designed to be permanently welded into compatible high-pressure pipework or flowline assemblies, providing a robust connection while retaining the ability to quickly connect and disconnect the union at the wing nut.

The hammer-style wing nut allows fast make-up and breakout, making FIG 602 unions well suited to high-pressure systems where equipment and flowline sections may require regular assembly, maintenance or reconfiguration.

Important

Pressure rating, bore, weld preparation, material grade, temperature range and applicable standards should be confirmed against the manufacturer's technical data and certification before installation.

Welding should be carried out using an approved welding procedure suitable for the union and adjoining pipe materials. Hammer union components should only be connected with compatible components of the same figure, size, pressure rating and specification.
