Tyne Pressure Testing is a recognised pressure testing facility specialising in exploration pressure testing of subsea equipment.

We have completed exploration pressure testing on a range of subsea mining equipment for the oil and gas industry in compliance with API standards. Hyperbaric testing, which is performed in our hyperbaric chambers, is commonly used by the exploration sector because of its ability to simulate water conditions from a few meters to thousands of meters.

Our hyperbaric chambers can simulate water depths down to 15,000 metres in depth, equivalent to 1,500 Bar/21,755 psi. This means that we can test and verify a product to operate under extreme, pressurised conditions. Hydrostatic testing is conducted in our environmental testing bays, testing up to 3,450 Bar/29,000 psi.

Other common testing for the explortation sector is nitrogen gas testing. This allows us to test components up to 2,000 Bar/29,000 psi. We also have the capability to pressure test components at temperatures ranging between -160oC and +300oC

Chamber TPT 5, our largest hyperbaric chamber, can simulate both pressures and temperatures down to 4,500m water depth. This is ideal for ensuring that equipment designs are fit for purpose when working in their operational conditions.
