The Graphite Seal, or graphite gasket, is one of the best-selling components manufactured by Star 21 International. We have mastered the art of producing this revolutionary product that is utilized for sealing purposes under extreme conditions like high temperatures and high pressure. This small circular component can tolerate high temperatures up to 1000°C and is 100% resistant to corrosion. Our graphite seals are remarkably used in cooling towers, chemical plants, heat exchangers, high-pressure pumping, petrochemical plants, electrochemical applications, and cryogenic environments, and they guarantee an excellent sealing performance.
Flange Insulation Gaskets Kit
The Flange Insulation Kit manufactured by Star 21 International is the most widely used corrosion controlling tool kit in Singapore. It is also used to control stray electric currents in piping at oil, gas, and water refineries, and chemical plants to increase the effectiveness of the cathodic protection systems. Our flange insulation kit includes a central flat or oval section gasket, an insulation sleeve per bolt, two insulating steel washers per bolt, and two plated steel washers per bolt. It contains four types of gaskets, which are: Type E, Type F, Type D, and Seal Type O. Our flange insulation kit ensures to prevent all kinds of leakages, and they act as an insulator between dissimilar metallic flanges that could be corroded without precautions. The flange insulation kits are generally available in 24 inches, however can be customized upon demand.
