InsoLion FS fire-safe flange gets Shell TAT approval

The InsoLion FS gasket is James Walker's performance isolation gasket and uses a patented triple seal design. This incorporates a coated metallic core housing a modified u-shaped TFM seal energised with a phynox spring. The location of James Walker’s triple seal design elements on the gasket face is meant to allow the gasket to be used across all types of flange styles including ring joint and raised face flanges.

With this configuration, the company says that the InsoLion FS combines fugitive emissions performance, chemical compatibility and electrical isolation with the capacity to maintain sealing performance after API 6FB 3rd Edition fire test.

To validate the performance of InsoLion FS, a third party witnessed successful testing that included fugitive emissions to Shell MESC SPE 85/300 2017 3.3.2, hot operational tightness (HOTT) Shell MESC SPE 85/300 2017 3.3.5 and electrical 1500V isolation Shell MESC SPE 85/300 2017 3.3.15 API 6FB 3rd Edition Fire Test

The company says that its InsoLion FS and InsoLion G11 variant (which also holds a Shell TAT approval) offers fugitive emissions levels significantly lower than those required under Shell MESC SPE 85/300 3.3.2 Class A (HS).
