James Walker launches new elastomers for oil & gas applications

Woking, UK – James Walker has released a new hydrogenated nitrile elastomer material suitable for the oil and gas industry.

Vermilion Seven has been formulated to provide enhanced resistance to rapid gas decompression (RGD) at elevated temperatures in addition to good resistance to sour conditions, said the sealing technology and materials specialist 1 June. 

Furthermore, the material has “outstanding physical robustness and improved extrusion resistance.”

Vermilion Seven, said the company statement, is James Walker’s “next generation” hydrogenated nitrile (HNBR) offering that is intended to take over from its signature Elast-O-Lion 101 material.

“Replacing market-leading materials is no easy task,” said product director Trevor Clarke commenting on the Vermilion range of materials that are replacing some of the company’s flagship high-performance elastomers. 

“We have taken a significant step forward, improving areas of performance to match technical and commercial demands of the industry without pushing so far that other areas have become compromised in the process,” he added.

Vermilion Seven is approved to Norsok M-710 annex A and B - ISO 23936-2 as well as API 6A FF/HH - ISO 10423. 

In-house product configured testing has confirmed sealing capabilities down to temperatures as low as -33°C.

The product achieved “a perfect ‘0000’ rating” in Norsok RGD testing at a temperature of 125°C, said James Walker.
