Endurance testing typically comprises of prolonged hydrostatic or gas testing conducted over a sustained period of time through the performance of repeated pressure cycles. This allows for real life operating conditions that a product is likely to experience over its lifecycle, simulated within a condensed window.

While life cycling can be performed on products within any sector in order to verify robustness, Tyne Pressure Testing has extensive experience in conducting endurance testing pressure cycling on products to API 17D.

API 17D has a requirement for a minimum 600 endurance test. These cycles are cumulative throughout the test and can be made up of a combination of PR2 dynamic cycles, hyperbaric cycles (Annex L) and endurance cycles run at atmospheric pressure and ambient temperature. Following the PR-2 and hyperbaric test, there are a further 200 endurance cycles required to meet the total of 600.

We hold expertise in conducting endurance testing on subsea oil and gas components as part of our adherence to the wider testing regime in API 17D. Typical products considered within this segment include valves, actuators, hot stabs and complementary critical components that form the basis of subsea production systems.

Our team of highly skilled test engineers are experienced in completing endurance testing for a range of clients. Clients have the opportunity to select our beginning to end, fully project managed testing service or can independently hire the chambers.

Can you endurance test my product?

Yes! At Tyne Pressure Testing we can conduct hydrostatic or gas tests on repeated pressure cycles over a period of time. This type of testing is favourable as it demonstrates the effect a product is likely to experience in its life time.

I have a range of products that require endurance testing, how long can I hire your chambers?

For as long as you need! We offer our clients the capacity to book our chambers for as long as they require. If you have a range of products that require endurance testing, speak to a member of our team.

Why choose us?

Facilities on-site

Opt for either an all-encompassing, fully project managed testing service provided by our experts and in-house engineering team, or, hire our pressure testing facilities to conduct independent testing.

Client Facilities

Our clients travel across the globe to utilise our pressure testing services and hyperbaric testing equipment. We will aim to support your connectivity to provide a comfortable working environment whilst you oversee product testing.

Whilst your product is undergoing the testing process, take advantage of our dedicated client offices, break-out area, Wi-Fi and conferencing facilities. If a client representative cannot travel to our facility, they can remotely log onto our IT system to stream live test data and video footage of their component being tested.

Reduced Lead Times

Working to a tight timescale? We can conduct 24 hour testing at our facility, subject to availability. Clients also have the option to complete testing in multiple chambers.

Our largest chamber, hyperbaric chamber TPT 5, is equipped with automated controls and an interactive system to improve efficiency and reduce loading times meaning this chamber can fill, load and pressurise in just 90 minutes!

Data Reporting

As standard, our clients receive full documentation and product certification after the testing is completed.

The majority of our hyperbaric chambers are fitted with subsea cameras and this video footage can be shared upon request.

Additional Client Services

We can offer additional services to help fulfil project requirements such as; assembly, data reporting, third party verification, logistics and storage and dedicated client facilities.

Third Party Verification

We can arrange for a third party witness to oversee your product testing and verification. We frequently work with leading authorities such as Bureau Veritas and Lloyd’s Register.
