Galvanic Corrosion Flange Insulation Kit Gasket for High Temperature
Galvanic corrosion is a common type of corrosion that occurs when two dissimilar metals are in contact in the presence of an electrolyte, such as water or saltwater. This type of corrosion can cause significant damage to metal structures, including flanges in pipeline systems.
To prevent galvanic corrosion in flanges, insulation kits with gaskets are commonly used. These kits include a gasket that is 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 should 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, 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 also provide other benefits such as preventing flange face damage, reducing the risk of leakage, and facilitating easier maintenance of the pipeline system.
In summary, galvanic corrosion in flanges can be prevented by using insulation kits with gaskets made 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. They are used for dissimilar material flanges and cathodic protection piplines to control losses due to corrosion. They can be sued to control stray electric currents in piping at oil, gas, water, refinery, and chemical plants, to increase the effectiveness of cathodic protection systems.
