Galvanic Corrosion Flange Insulation Kit Gasket for High Temperature
Galvanic corrosion is a prevalent form of corrosion that arises when two dissimilar metals are in contact with an electrolyte, such as water or saltwater. This type of corrosion can cause significant damage to metal structures, including flanges in pipeline systems.
In order to prevent galvanic corrosion in flanges, it is common practice to use insulation kits with gaskets. These kits include a gasket made of a non-conductive material, such as rubber, plastic or fiberglass, which is placed between the flange faces to electrically isolate them from each other. The gasket material must be compatible with the fluid that will flow through the pipeline system and be able to withstand the pressure and temperature conditions of the system.
The flange insulation kit with gaskets prevents galvanic corrosion by creating a barrier between the dissimilar metals in the flange assembly, thereby eliminating the flow of electrical current between them. This helps to prevent the formation of electrochemical cells that lead to galvanic corrosion.
In addition to preventing galvanic corrosion, flange insulation kit gaskets offer a range of other benefits, including preventing damage to flange faces, reducing the risk of leakage and facilitating easier maintenance of the pipeline system.
To summarise, the prevention of galvanic corrosion in flanges can be achieved through the use of insulation kits with gaskets composed of non-conductive materials. These kits prevent the flow of electrical current between dissimilar metals, thus reducing the risk of galvanic corrosion and maintaining the integrity of the pipeline system.

Insulating Gaskets are used for sealing and isolating flanges to prevent corrosion. These products are used for dissimilar material flanges and cathodic protection pipelines. They are used to control losses due to corrosion. These products can be used to control stray electric currents in piping at oil, gas, water, refinery and chemical plants. This increases the effectiveness of cathodic protection systems.
