Flange Isolating Gasket Kit Set for Flat Face Flange
A Flange Isolating Gasket Kit Set is a collection of gaskets and sleeves designed to electrically isolate flanges in a pipeline, and provide cathodic protection to prevent corrosion. The Flange Isolating Gasket Kit Set includes multiple gaskets and sleeves to fit different sizes and pressure ratings of flanges.
The Flange Isolating Gaskets are made of non-conductive materials such as high-density polyethylene (HDPE) or glass-reinforced epoxy, and are placed between two flanges to prevent electrical current from flowing between them. The sleeves are made of the same materials and are placed over the bolts and washers that connect the flanges, to ensure that they are also electrically isolated.
The Flange Isolating Gasket Kit Set is commonly used in pipelines that transport oil, gas, or other chemicals, where electrical isolation is required to prevent galvanic corrosion. Galvanic corrosion can occur when two different types of metals are in contact with each other in the presence of an electrolyte, such as saltwater or moisture. The cathodic protection components in the kit help to supply an electric current to the pipeline to protect it from corrosion.
The Flange Isolating Gasket and sleeves in the set are designed to meet the requirements of the pipeline, including the size and pressure rating of the flanges. Flange Isolating Gasket Kit Sets are also designed to be easy to install and remove, and are reusable for future pipeline maintenance.
Overall, the Flange Isolating Gasket Kit Set is an important component in pipeline infrastructure that helps to ensure the safety and reliability of pipeline transportation. Flange Isolating Gasket Kit Set helps to prevent galvanic corrosion and ensure proper electrical insulation, reducing the risk of pipeline failure and environmental damage.

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.
