Flange Insulation Kits
The OGF Flange Insulation Kits consist of one full-length insulating sleeve, two insulating washers and two steel washers for each of the bolts in the flange assembly. The purpose of the insulating sleeves is to electrically separate the bolts from each side of the flange, while the insulating washers provide electrical insulation for each of the nuts attached to the bolts. This method of insulation provides the user with a high-reliability solution to complete the electrical insulation of a flanged joint.
OGF insulating kits/sets are designed to be used with our specialty line of high-strength, high-reliability insulating gaskets and are available for use in all types of flanges including raised-face, flat-face and RTJ. The gaskets and kits are sized according to the relevant flange specification including ANSI, API, DIN, BS, AS, MSSP, etc. Special insulating set configurations can be manufactured upon request for custom requirements that don't conform to standard specifications.
General Properties and application
- Extremely high reliability sealing and insulating solution for all aggressive chemical & critical services.
- Formation of isolation bridge for better electrical resistance
- The best for use in high chloride applications that could cause corrosion cracking with stainless steel core
- Designed to withstand corrosive environments, including high concentrations of CO2, H2S, produced water, etc
- Avoid the need of exotic metal core because it breaks the metal to metal ion flow hence minimize the extra expanse.
- Pressure activated seals provides high confidence sealing and eliminates costly leaks.
- Available with G11 retainer for up to 180 °C
- Can seal mismatch RTJ Flange with Raised Face Flanges.
