Hammer Unions

Introduction to Hammer Unions


Hammer Unions are widely used throughout the energy industry. Hammer Unions come in many sizes, shapes and pressure ratings, and when used correctly they are a safe and reliable means of transporting fluid. Perhaps one of the most critical elements to correct hammer union use is that the two halves are compatible. There are, however, combinations which will allow a high pressure hammer union to be mated with a low pressure union, leaving the user at risk of hose failure and serious injury.

In this course we will look at hammer unions in detail, maintenance, safe use and the consequences of mismatching unions.
