FLANGE ISOLATION GASKET KITS

Flange Isolation Gasket Kits are designed to maintain the integrity and reliability of the pipeline and piping system through safety and corrosion protection.

Flange Isolation Gasket Kits provide an effective seal and electrical isolation of flanges. By eliminating metal to metal contact, static current is halted to prevent corrosion and aid in the cathodic protection of the pipe.

 Flange Isolation KitConstructed of high quality materials that have a high dielectric constant and low water absorption, our Flange Isolation Gasket Kits are available for all size flanges, ranging from 1/2″ to 144″ in all ANSI and API classes.

In addition, utilizing Flange Band Protectors in conjunction with flange insulation kits further enhances reliability and reduces risk. Drake flange protectors seal the flange internals to prevent foreign objects or debris from lodging between the flanges, forming a bridge, creating a short, and compromising the entire cathodic protection system.

Ordering the correct Flange Isolation Gasket Kit requires knowing the specifications and type of service for your particular application.
