Norsok M-710 - Working to a World-Class Standard.
For our customers in the oil and gas industries, it's critically important to know they can rely on components that will function effectively in incredibly hostile environments. So to give them an unequivocal assurance of quality, performance and durability, we've long since worked to the NORSOK M-710 standard - the internationally recognised benchmark for all non-metallic seals and bearings.
In addition, although materials can be approved in five different grades, we're one of the few manufacturers to exclusively use the top two grades alone - not only guaranteeing the highest possible levels of quality but also providing a greatly reduced margin of error where performance criteria are concerned.
Originally developed by the Norwegian petroleum industry, the M-710 standard means that materials must achieve accepted criteria for both rapid gas decompression (RGD) - also known as explosive decompression (ED) - and sour gas ageing (H2S), both of which are proven indicators of long-term performance and viable life expectancy.
RGD testing establishes a material's resistance to blistering and cracking when sudden changes in pressure and temperature occur, with conformation to M-710 proving structural resilience and seal integrity in hostile sub-sea applications.
Sour gas testing analyses potential degradation over extended periods of time, assessing criteria such as tensile strength, swelling, elongation and hardness to ensure constant, predictable performance far beyond the likely practical life of any particular component.
With our experience and expertise in this field, we've been able to develop and supply a wide range of seals and custom-moulded components, with our customers including some of the most successful oil and gas companies in the UK, Scandinavia and further afield.
