James Walker, whose US headquarters are located in Illinois, has announced that the Vermilion® Three has become the first and only elastomer to receive Shell TAT approval to Shell MESC SPE 85/301.
In 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.
Vermilion Three is a new fluoroelastomer material (FKM) and 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.
