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.The use of insulating gasket is to avoid electrical charge continuity and it is mostly used at above ground & U/G interphase to avoid cathodic protection. Very common in pipelines where insulating joint, which is very costly, may be avoided by using insulation gasket assembly This is also used extensively at dissimilar metal flanged joint wherein the difference of electronegativity of the 2 disimilar metal may lead to galvanic attack/corrosion.Insulation kit Gaskets provides greater resistance to over compression and cracking. These insulation kits are also used to electrically isolate flange joints, preventing flow ofelectrostatic charges along the pipeline.For best results, the flanges must be wrapped with Flange Band Protectors. So foreign materials are prevented from collecting and creating a bridge, thus shorting out the isolation.
FLANGE ISOLATING GASKET KITS Flanges, the most common trouble area, need to be sealed properly to prevent leakage and must also be cathodically isolated to prevent stray currents which cause undo corrosion and eventual breakdown of the metal.
