Jul 19, 2024 · What Does Insulating Flange (FIK) Mean? Insulating flanges are those flanges equipped with plastic pieces that insulate and prevent the flow of an electric current between two metal surfaces. Insulating flanges are used in cathodic protection systems to …

Insulating gasket sets or Flange insulation kits play an important role in such cases. They are designed for electrically insulating the flanges. They act as an insulator between dissimilar metallic flanges.

Flange insulation kits are the most widely used form of controlling losses due to corrosion. They can be used to control stray electric currents in piping at oil, gas, water, refinery and chemical plants and increase the effectiveness of cathodic protection systems and confine or eliminate electrolytic corrosion.

GPT manufactures PSI and Pikotek brands of flange isolating kits and gaskets. Available as kits or components, these solution are designed for complete isolation for flange assemblies.

Jun 22, 2023 · Insulating the flanges can increase the chance for leakage when a flange is cooled rapidly from the inside (such as when a wash-oil is run through a system). Under these conditions, the bolts cool slower than the flanges, resulting in a …

Insulating the flanges can increase the chance for leakage when a flange is cooled rapidly from the inside (such as when a wash-oil is run through a system). Under these conditions, the bolts cool slower than the flanges, resulting in a measureable (6,000 to 10,000-psi) drop in stud load.

Pikotek Flange Insulation Kits are designed to work in conjunction with Pitotek's insulating gaskets (Pikotek VCS, PGE and RC) to effect the complete electrical insulation of a flanged assembly.

ISOPRO-LSE IS A FLANGE ISOLATION GASKET COMPRISING OF TWO SPRING ENERGISED PTFE SEALS LOCATED IN PRECISION MACHINED OFFSET GROOVES IN A GLASS REINFORCED EPOXY (GRE) CARRIER.

Insulation kits are designed to prevent galvanic corrosion between flanges of dissimilar metals, for example a carbon steel flange bolted to a stainless steel flange.

By simply inserting a flange isolation kit (FIK), the metallic path between the component and the pipeline is eliminated and galvanic corrosion is then mitigated. When an FIK or MIJ is made to the pipe bore, this can dramatically reduce microbial induced corrosion (MIC) issues.
