Hammer Unions
A connection common in the oil industry consisting of two joints coupled by a threaded nut. Protrusions on the nut are hit with a sledgehammer to tighten the connection and energize the seals. Hammer unions are commonly used on treating iron because of their ability to be quickly made up or broken down.
We provide Unions ranging from 1″ to 12″ and can handle pressures up to 15000 psi CWP ( cold working pressure). Available with line pipe, butt-weld or socket weld connections, our unions are interchangeable with other name brand manufacturers that adhere to industry standards.
To ensure customer satisfaction, our Unions come with full trace-ability and are manufactured from the highest quality raw materials. All of our products are type approved by Det Norske Veritas. In addition, they meet API 6A and API 16C requirements, as well as NACE-MR-01-75 (sour gas service).
