Insulating Flange Kit
Gasket sets for flange insulation are designed to ensure the integrity and reliability of the pipeline and piping system through safety and corrosion protection. By eliminating metal-to-metal contact, static flow is stopped to prevent corrosion and aid in the cathodic protection of the piping system.
Flange insulation gasket kits provide both effective sealing and reliable electrical insulation of flanges. Made of high-quality materials with high dielectric constant and low water absorption. Flange insulation gaskets kits are available in different configurations to meet any possible need. Flange insulation gasket kits come in all DIN, ASME and API classes.
Parts of flange insulation kit
Each flange insulation kit consists of..
1.1 central flat or oval gasket
2.1 insulating sleeve for each bolt
3.2 insulating steel washers for each bolt
4.2 sheet steel washers for each bolt
All these parts are made of unique materials with chemical stability, dielectric properties and minimal water absorption to achieve the purpose. Complete sets are individually packaged and labeled with flange size, rating, type and material combination. Insulation sets are normally accessible up to 24 inches, but custom higher nominal sizes can be manufactured upon request.
Type E
This style kit contains a full face gasket that has the same outside diameter as the flanges. This style gasket will prevent foreign material from collecting and creating a bridge, thus shorting the cathodic isolation. Type E gaskets are available in, neoprene-faced phenolic, and high temperature materials.
Type F
This gasket fits the raised face flanges. The outside diameter of the gasket is slightly smaller than the inside diameter of the bolt circle. This gasket can be used on both raised and full flanges. Type F gaskets are available in neoprene-phenol and high-temperature materials. (It is recommended that flanges be wrapped with flange band protectors to prevent foreign material from collecting and forming a bridge, shorting the insulation).
