Tyne Pressure Testing is a hyperbaric testing facility located in Newcastle upon Tyne.

Our engineers are experts in both internal pressure and external hyperbaric testing and available to provide specialist independent testing advice and guidance.

Our hyperbaric test chambers can be pressurised up to 1,500 bar/21,755 psi, surpassing the deepest known point on Earth. Our offering includes one of the largest commercially available chambers in the world.

At 4.5m long and 2.5m in internal diameter, our largest hyperbaric testing chamber is unique as it can test to water depths of up to 4,500m and is capable of simulating temperatures down to -2°C. Surrounded by sophisticated automated loading procedures, TPT 5 can load, fill and pressurise within 90 minutes.

Hyperbaric Testing

Our dedicated facility operates nine hyperbaric chambers which can pressure test as high as 21,755 psi, in chambers up to 6.5m long. This includes one of the largest commercially available hyperbaric chambers in the world.

Hydrostatic Testing

Hydrostatic testing is completed in line with client specifications and international standards such as API and ANSI Class.

This type of hyperbaric testing is common on subsea and topside products amongst our clients within the oil and gas industry. It’s regularly carried out as part of our wider factory acceptance testing (FAT), in line with industry standards such as API 6A, API 6D, API 6DSS and API 17D up to 2,000 bar.

Factory Acceptance Testing

We offer flexible factory acceptance testing (FAT), including gas testing or hydrostatic testing.

As part of our service, and to make your experience as easy as possible, we can arrange for a third party witness to oversee your factory acceptance testing. We work with certified authorities such as Bureau Veritas and Lloyd’s Register.

Temperature Testing

Temperature testing up to +250°C, down to temperatures as low as -160°C, is conducted within our environmental testing bays.

Testing temperatures of -160°C to +250°C, alongside the application of high pressure gas, allows us to simulate extreme operating conditions and verify that your components can safely function under these conditions. We conduct API 6A PR2 testing, as part of our temperature tests.

Our unique large hyperbaric chamber has the ability to simultaneously reach temperatures down to -2°C, whilst testing at water depths down to 4,500m (6,526 psi). Read more about TPT 5 and its capabilities here.

Gas Testing

We can conduct high pressure gas testing or leak testing using either nitrogen or helium gas.

Gas testing is typically conducted within our testing bays measuring up to 6m long.

Helium Leak Testing

The molecular composition of helium is a lot smaller than that of nitrogen, therefore helium leak testing is ideal for our clients looking to detect small leakage rates.

Contact us in order to discuss any helium leak testing requirements so that we can create a testing solution specifically designed for you.

Buoyancy Testing

Buoyancy testing, or buoyancy loss testing, is performed in our hyperbaric chambers.

Buoyancy testing measures the water ingress in a module or component whilst it is under external pressure. This is conducted over a desired period of time and is accurately facilitated by our onsite scales and/or load cells.

Validation of such modules and componentry ensures that your products are fit-for-purpose prior to deployment.

Endurance Testing

Endurance testing typically comprises of hydrostatic testing or gas testing conducted over a prolonged period, through multiple cycles.

Endurance testing can be performed on any product, for any sector, in accordance with your specifications. It is most common amongst our clients within the oil and gas industry. Endurance testing is frequently conducted as part of an API 17D test for the design and operation of subsea system equipment.

Destructive Testing

Destructive testing also known as burst testing or collapse testing verifies the design calculations of new products.

Destructive testing enables our clients to pinpoint the weakest point within a component’s design and understand its structural integrity. This is typically conducted during the research and development process.

We are committed to supporting the research and development of new products; creating bespoke testing solutions and contributing to progressing the future of our industry and that of any other sector.


Flushing is a common cleaning process that ensures the removal of any debris following the testing of a product, component or sub-assembly.

Flushing is a preventative measure to minimise the risk of contamination occurring within the tested item, and is often carried out to clean and veritfy a product both pre and post test.

Vacuum Leak Testing

Vacuum leak testing can be used to determine the air-tight integrity of a component. We have a vast experience in conducting this form of test with an ability to perform with atmospheric pressure down to a vacuum of 650 mbar.

On-site Pressure Testing

The ability to perform services at a customer site has proved favourable for clients looking to oversee the final testing process at their own facility. We can project manage the migration and setup of all necessary equipment at site prior to the deployment of skilled test technicians to perform the desired test sequence. This ensures the same level of exceptional knowledge, service and support is available throughout the execution of the test programme in the same way as if conducted at the Tyne Pressure Testing facility.
