Advance in DuPont™ Kalrez® Parts Overcomes Challenges of Harsh Oil and Gas Environments

Posted on: July 16th, 2012 by admin

Reliability engineering for harsh oil and gas drilling environments such as deep water and shale has just taken a major step forward with the advent of DuPont™ Kalrez® 0090 perfluoroelastomer O-rings. In rigorous third-party testing for rapid gas decompression (RGD) resistance per the NORSOK M-710 Rev 2 standard, Kalrez® 0090 O-rings received the best possible rating of 0000. The tests were conducted by the independent Materials Engineering Research Laboratory Ltd. (MERL) in the U.K. In contrast to Kalrez® 0090 parts, other competitive seals can pass the minimum requirements of NORSOK M-710 with multiple internal cracks developed during test cycling.
