About Us

Yes. We can quote the cost of our services and the use of our testing equipment as a one-off cost, or as a daily rate depending on your requirements. We can also quote in different currencies.

Pressure testing costs for our full turnkey service includes: bay/chamber rental, skilled labour, test rig, consumables, specific tooling requirements and a final documentation pack. We can also include written test procedures if required and arrange third party certification through companies such as Lloyds Register and Bureau Veritas.

We can provide our pressure testing services to any sector. Please get in touch with one of our experts to submit an enquiry or view relevant case studies here.

Yes. As part of our flexible approach to supporting clients, we will gladly support requirements to conduct independent testing should there be a requirement to rent a bay or chamber only.

Yes, our clients have complimentary access to dedicated offices with wi-fi, as well as breakout areas, and use our conferencing facilities to allow them to work on-site whilst overseeing testing.

Hyperbaric testing is the application of external pressure to a component and is carried out in a specialist hyperbaric chamber to simulate extreme pressure environments. The component may be retained inside of the hyperbaric chamber by its own weight where heavy industrial products are concerned.

Retaining straps are used to hold buoyancy modules in place, or racking where separation is required for fragile components. Bespoke tooling can also be manufactured for specialist items.

Products are placed in hyperbaric chambers, which are often cylindrical in shape, before water is injected and then pressurised using pumps.

For every 10 metres below sea level, a water pressure of 1 bar is exerted. So, if a product was going to be deployed at 1,000 metres below sea level, the weight of the pressure on that product would be 100 bar.

High pressure instrumentation and pumping systems, rated over and above the maximum pressure of each individual chamber, are used to feed inhibited water into each chamber from on-site storage tanks. This water creates the desired pressure inside of the chamber.

Hyperbaric testing concerns the application of external pressure to a product. The product is housed within a pressure vessel/chamber which acts as the barrier to retain the external pressure around the test subject.

The primary reason for doing this is to replicate actual conditions an assembly will see in installed life, meaning the external pressure will first and foremost validate the structural integrity of the component. Secondary to that, any ingress of pressure into the component would highlight a leak path(s) which may compromise areas such as sealing arrangements or welded joints.

The principle of hydrostatic testing is very similar to hyperbaric testing in that this will also verify structural integrity and any leak paths, as well as utilising water as the test medium. The fundamental difference is that a hydrostatic test concerns the internal pressurisation of a component, rather than subjecting it to external pressure. The likes of a product sealing arrangement will still very much but scrutinised but with pressure effectively pushing ‘in-to-out’ rather than ‘out-to-in’.

Certain components may be subjected to a hydrostatic and hyperbaric test simultaneously e.g. subsea pipeline equipment. These products would typically feature primary, secondary and tertiary sealing barriers to withstand excessive levels of internal and external pressure.

Hydrostatic testing is performed by filling a component with water and pressurising it to test its integrity. Appropriate connections are required to connect the pressure inlet of the product to the on-site instrumentation comprising pumps, regulators, accumulators, valves and pipework. This system is then used to increase the water pressure until the desired specification is reached. Calibrated pressure transducers are used to monitor the internal pressure as it rises. The pressure is taken up and held. If the pressure drops, this indicates that there is a leakage.

If there is a requirement to monitor visible leakage, submerged gas testing can be used as an alternative to hydrostatic testing as leak paths are identified through the presence of bubbles. Submerged gas testing can also be performed at Tyne Pressure Testing.

This method of testing is generally known as non-destructive testing and it is very rare that the product is destroyed, but it can happen.

Hydrostatic testing is used to prove that a product is fit for purpose and that it can retain its working pressure without any leaks. Therefore the worst case is generally that we will see a leak path, rather than the product being completely destroyed.

Hydrostatic testing costs can vary depending on the size of the component and how comprehensive the test schedule is. The price is usually calculated based on an hourly rate and a lump sum quotation can be provided during the product development stage to help with budget forecasts.

We recommend that you contact us early in the project for a quotation.

Hydrostatic testing is mostly used to test that a prototype or new design tweak is functional and leak free. It is also common for this testing to be carried out on a production batch sample test or if the standard dictates every production unit. Testing can be carried out on existing components in the field and this is dictated by the maintenance schedule of an application normally by the end user.

Factory acceptance testing is a common method used after the design and fabrication stage to verify that the product operates properly and helps to identify any problems before the final stages.

Factory acceptance testing (FAT) at Tyne Pressure Testing can be a simple gas test or hydrostatic test with minimal hold period at pressure or can encompass a series of back-to-back tests that will verify each independent sealing system within a final product assembly. We will fill the component with either water or nitrogen and check for any leakage.

Factory acceptance testing (FAT) helps assure the manufacturer and end user that there are no anomalies and the product meets all specifications. Manufacturers can save time and money when completing this type of testing before reaching the final stages and can feel confident when the product goes live.

Factory acceptance testing (FAT) is bespoke, and therefore each test differs dependent on what is being tested. Some components require further testing, dependent on what they are being used for. This includes; calibration, equipment sealing and operating functions.
