Kalrez® 0090 perfluoroelastomer Orings from DuPont™ are specifically designed for the oil and gas industry to provide outstanding resistance to rapid gas decompression (RGD) and explosive Decompression (ED).

Kalrez® 0090 for Oil & Gas

Kalrez® 0090 was tested by independent UK-based Materials Engineering Research Laboratory, and passed the NORSOK M-710 Rev 2 standard for rapid gas decompression with the highest possible rating of 0000.

O-rings with lower ratings are likely to suffer greater cracking when exposed to pressure cycling. Once a crack is initiated in an o ring, gas will accumulate at the next pressure cycle, eventually leading to a complete crack across the section, which could lead to seal failure.

SealsMERL also certified the excellent resistance of Kalrez® parts to sour fluid ageing, including multi-phase fluids containing hydrogen sulfide. Explosive decompression (ED) performance has also been validated by customers in the US and Europe.

Vespel® high performance Backup Rings

Application Summary

Vespel® CR-6100 parts from DuPont™ perform as back-up rings in a wide range of high-pressure pumps used in hydrocarbon processing and refining. Vespel® CR-6100 parts outperform those made from alternative materials such as polyetheretherketone (PEEK) in several ways. These include higher temperature resistance, more mechanical strength and nearly universal chemical resistance. They are recognized under the latest edition of the ISO 13709 International Standard and the American Petroleum Institute’s API 610 Standard.

Vespel® CR-6100 is fast and easy to machine.
