Troubleshooting Guide for O-rings and Seals

Posted on: July 20th, 2012 by admin

We understand that you may need assistance, and/or extra information on troubleshooting for O-rings and seals, and Dupont have kindly supplied this selection of guides below.

These troubleshooting sections from Dupont, include photos of O-rings and seals damaged from chemical, thermal, or mechanical attack. By understanding the cause of O-ring failure, proper selection of an alternative elastomer or seal design can help improve seal life.

For help in evaluating your sealing performance, DuPont also offer assistance in compound selection and seal design for Kalrez® parts. Before an in-depth analysis of O-ring failure can be provided, application data, such as process chemicals, temperatures, etc. must be supplied.

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.
