New sealing material meets stringent oil & gas standard
Trelleborg Sealing Solutions offers the first perfluoroelastomer sealing material to satisfy Norsok M-710 Rapid Gas Decompression test conditions
Trelleborg Sealing Solutions launches its XploR™ range of Explosive Decompression Resistant materials specifically formulated for the oil & gas industry. Fully compliant with NORSOK M710, the range includes Isolast® XploR™ J9513, the first perfluoroelastomer on the market to meet the requirements of the stringent RGD test.
The XploR™ range from Trelleborg Sealing Solutions is a suite of advanced elastomers especially developed for oil & gas applications. The portfolio 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.
“As a seal developer and manufacturer with a significant proportion of our business in the oil & gas industry, Trelleborg Sealing Solutions has focused on Explosive Decompression (ED),” says Bill Allan, Oil & Gas Segment Manager for Europe. “We have invested considerable amounts of development time and money on the quest to find Explosive Decompression Resistant (EDR) materials. This gives great benefits to our customers, providing increased seal life.”
The XploR™ range is available in all standard international O-Ring sizes and cross sections, along with custom-engineered solutions and specially designed seal profiles.
About Explosive Decompression
Gas or gas mixtures in contact with elastomer surfaces 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. This can lead to crack initiation within the body of the elastomer. These cracks propagate internally and this can cause void formation or cracks to appear on the elastomer surface that significantly reduce seal integrity.
