Pressure installation testing

High-pressure equipment stays verified and operational when testing takes place in a dedicated, controlled environment. With dedicated wet and dry testing facilities, Control Union confirms equipment integrity and manages failure risk before it reaches the field. Operations are supported with minimal unplanned disruption, while stakeholders receive clear, documented evidence of readiness.

Control Union

    Safety and independence in pressure vessel testing

    Control Union operates a state-of-the-art facility rated for pressure equipment testing up to 20,000 psi (1,379 bar), covering both offshore pressure testing and onshore applications.

    Because Control Union is not affiliated with insurers or maintenance contractors, every result is 100% objective and free from conflicts of interest. This structural independence means inspection outcomes withstand regulatory scrutiny and give organisations full confidence in equipment status before critical deployment.
