We are a trusted pressure testing facility for the civil nuclear industry in developing products and upgrading applications.

A common type of pressure testing completed for the civil nuclear industry is temperature testing. Temperature testing is conducted within our 6 metre long environmental test bays at temperatures of -160˚C to +300˚C. High pressure gas is applied to verify that the component can safely function in these conditions. We work to meet industry standards BS EN 13480-5 and ASME B31.3.

Tyne Pressure Testing is proud to be part of the North East Energy Catalyst, a ground-breaking partnership to unite the North East’s leading energy innovation, demonstration and delivery capabilities, leading the way to find solutions to global energy challenges

We hold the Fit For Nuclear status which demonstrates that we are are trusted supplier to work with clients in the civil nuclear sector to test components including; heat exchangers and emergency reactor shutdown system pipework.
