Teadit GR 1700 Graphite HOCHDRUCK

APX2 HOCHDRUCK Graphite Sheet with Multiple Foil Inserts TEADIT GR1700 - SIGRAFLEX APX2 Hochdruck is a multilayer, high-strength gasket sealing sheet designed for high-temperature applica tions . The sheet is comprised of 0.020” thick layers of highly oxidation resistant SIGRAFLEX APX2  exible graphite and 0.002” thick inserts of 316L stainless steel foil, manufactured with SIGRAFLEX Hochdruck technology. Properties Teadit GR 1700 APX2 Hochdruck is speci cally designed for high temperature  at gasket applications. It combines the outstanding weight loss characteristics of SIGRAFLEX APX2  exible graphite and reinforcing layers of metal in SIGRAFLEX Hochdruck technology. Teadit North America. 10545 Red Blu Rd - Pasadena - TX - 77507 Phone: 281-476-3900 - Fax: 281-476-3999 - e-mail: sales@teadit.com - www.teadit-na.com Application Teadit GR1700 is commonly used in pipe  anges, equipment and pressure vessels; non-typical geometry  anges tongue/ groove and heat exchanger  anges. It is also suitable for use in the manufacture of gaskets for sight glass, pumps,  ttings and valves, etc. Gaskets made from this type of sheet perform well in critical applications due to high mechanical strength and blow-out resistance, 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 Typical Physical Properties: Bulk Density - ASTM C559 70Lb/ft 3 Compressibility - ASTM F36 35% Recovery - ASTM F36 15% Creep Relaxation - ASTM F38 - ( exible graphite only) <4% Carbon Content - ASTM D5373 ≥98% Ash Content - ASTM C562 ≤2% Total sulfur - ASTM D4239B <300ppm Total chloride - ASTM 4208/D4327 ≤25ppm Oxidation rate in air @ 670°C - 1238°F - LECO TGA ≤1.0% Number of Inserts Number of 316L SS foil Inserts 1/16 thk 2 Number of 316L SS foil Inserts 1/8 thk 5 Availability Size: 59.1 x 59.1 in Thickness: 1/16”, 1/8” Temperature Minimum: - 418 ° F (-250°C) Maximum: approximately 1202 °F (650°C) Pressure 3600 psi (250 bar) Thickness (in) “m” “y” (psi) 1/16 2.5 3000 1/8 3.2 3500 “m” and “y” Values of SIGRAFLEX APX2 is superior to that of standard grades of graphite foil. This is re ected by its mass loss curve, whose temperatures for any given mass loss are about 150°C higher. The graph opposite shows weight loss in air as a function of temperature.
