GR 1701High Temperature Graphite Sheet with Multiple Foil Inserts

Description and Applications

Teadit® GR1701 is commonly used in pipe flanges, equipment and pressure vessels; non-typical geometry flanges tongue/groove and heat exchanger flanges. It is also suitable for use in the manufacture of gaskets for sight glass, pumps, fittings and valves, etc.

Properties
TEADIT® GR1701 is a multilayer, high-strength gasket sealing sheet designed for high-temperature flat gasket applica tions. The sheet is comprised of 0.020” thick layers of highly oxidation resistant flexible graphite and 0.002” thick inserts of 316L stainless steel foil. Teadit® GR1701 combines the outstanding weight loss characteristics of oxidation inhibited grade flexible graphite and reinforcing layers of metal.

Construction
The layers of graphite and stainless steel sheets are connected to each other with high strength using a special process. The impregnation of the sealing plate reduces leakage, improves handling and provides excellent “anti-stick” capabilities when removed from the flanges. Gaskets made from this type of sheet perform well in critical applications due to high mechanical strength and blow-out resistance. GR1701 has working pressure resistance up to 3600 psi (250 bar), excellent chemical resistance, very low cold or hot relaxation, and a maximum permissible gasket stress. Among its advantages, there is good conformation to sealing surfaces, excellent torque retention and high sealability. The thermal stability of GR1700 is superior to that of standard grades of graphite foil.
