Vermilion Three gains Shell TAT approval

Hot on the heels of its launch as part of James Walker’s new generation line-up of high performance elastomer materials for the oil and gas industry, Vermilion® Three has become the first and only elastomer to receive Shell TAT approval to Shell MESC SPE 85/301.

Vermilion Three certificateIn third party testing, O-Rings manufactured in Vermilion Three achieved a ‘0000’ rating - zero damage - when subjected to ISO23936-2/Norsok M-710 testing for resistance to rapid gas decompression (RGD). The Shell MESC SPE 85/301 standard requires more challenging test conditions for RGD resistance, being carried out at 150°C, which is 50°C higher than the standard temperature required for ISO23936-2/Norsok M-710. Given that a material’s RGD performance is highly sensitive to temperature, achieving a ‘0000’ rating at 50°C above the industry test standard is a significant advance in capability over current material technology.

"This achievement is a great example of how we are extending the performance boundaries of elastomer materials with our new Vermilion range," explains Trevor Clarke, product director for high performance elastomers at James Walker. "Vermilion Three is currently the only elastomer material approved for use where Shell MESC SPE 85/301 is specified and we anticipate further customer approvals across the range of Vermilion materials as our test programme continues."

Vermilion Three is a new fluoroelastomer material (FKM) offering excellent temperature performance and rapid gas decompression (RGD) resistance plus the typical FKM tolerance of H2S, aromatics and hot water. It is part of James Walker’s new generation Vermilion materials which have been specifically developed to meet the increasingly challenging conditions faced in critical oil and gas applications.
