Insolion® G11

The Insolion G11 gasket offers excellent electrical isolation for applications at a higher temperature range.

  • Oil & Gas

Following the same highly effective design as the Insolion G10 with a modified u-shaped TFM seal energised by a phynox spring, this version uses a G11 GRE composite material that extends usage to higher temperatures.

This seal is bonded to a high strength G11 glass reinforced epoxy and 316 L stainless steel composite core. The complete flange isolation kit supplied with the gasket includes G11 bolt sleeves and isolation washers as standard and will offer extremely high levels of electrical isolation even at elevated temperatures.

  • Flange isolation for critical applications in the oil, gas and other processing applications
  • Media compatibility with natural gas, oils, other hydrocarbon media and many corrosive environments
  • Specified for plant wide use on the majority of flange specifications including ASME, API, EN, BS and DIN
  • Flange insulation and electrical isolation in conjunction with cathodic protection
  • Insulation between dissimilar metals / flanges to prevent galvanic corrosion
  • The position of the TFM spring energised seal allows the gasket to be used across all types of flange styles including ring joint and raised face flanges

  • Maximum temperature: +180°C (+356°F)
  • Minimum temperature: -45°C (-50°F)
  • Maximum pressure: 69 MPa/690 bar (10000 psi) (ASME Class 2500)

  • TAT approved to Shell MESC SPE 85/300 3.3.2 Class A (He)

  • Insolion G11 can be supplied in sizes from NB 1/2" to 40" diameter to match the majority of flange specifications and can be manufactured in IBC and full face styles
  • Custom dimensions and sizing options are available upon request
  • Insolion G11 is supplied as a kit suitable for the specific flange size and class rating required. This kit includes:
  1. Insolion G11 gasket
  2. G11 bolt sleeves
  3. G11 washers
  4. Metallic backup washers in 316 stainless steel
  5. Fitting guide
