By optimising the material specification and design of each component that makes up an Insolion gasket we have produced an isolation gasket kit with the widest possible performance envelope.
The combination of materials used in the construction of Insolion gaskets provides a corrosion-resistant and maintenance-free solution that offers protection to flange faces from media-induced corrosion.
Insolion gaskets offer an effective seal between mismatched ring-joint and raised-face flanges where temperatures or pressures are unsuited to the use of phenolic gaskets.
Shell TAT approval
Our Insolion G10, G11 and FS (fire-safe) variants have all been third party tested and approved, significantly outperforming the fugitive emissions requirements of Shell MESC SPE 85/300 3.3.2 Class A. (Copies of the relevant Shell TAT approval certificates are available on request). In addition, Insolion FS has also been tested and approved by a third party test house to API 6FB 3rd Edition fire test.
The Insolion FS gasket is James Walker's premium performance fire safe isolation gasket and utilises a patent pending triple seal design.
The Insolion G10 gasket consists of a modified u-shaped TFM seal energised with a phynox spring.
The Insolion G11 gasket offers excellent electrical isolation for applications at a higher temperature range.
The Insolion GRE gasket consists of a G10 glass reinforced (GRE) carrier with two modified PTFE sealing faces.
The Insolion HT flange isolation kit utilises high temperature sealing materials for raised temperature capability.
