Explosive Decompression Resistant Materials for Oil & Gas Industry

By Design World Staff | August 5, 2009

When gas or gas mixtures contact elastomer surfaces (such as those found in seals) they can be absorbed under pressure. At high pressure, absorbed gas is in a compressed state. When external pressure is reduced, either rapidly or over a relatively short period of time, the compressed gas rapidly expands within the elastomer, which can lead to cracks in the material. These cracks propagate internally, which can cause void formations to appear on the elastomer surface that significantly reduce seal integrity.

The XploR™ range of advanced elastomers includes compounds in HNBR, FKM and Isolast® Perfluoroelastomer (FFKM), each of which demonstrates best-in-class Explosive Decompression Resistance (EDR) for its material type. In independent tests, materials within the XploR™ range were able to satisfy both the NORSOK M-710 sour service and Rapid Gas Decompression (RGD) test conditions. The XploR™ range is available in all standard international O-Ring sizes and cross sections, along with custom-engineered versions and specially designed seal profiles.
