New Sigraflex APX2 Hochdruck technology sheet services high temperature applications
We are pleased to announce the availability of high temperature gaskets produced from Teadit GR1700 sheet. Teadit GR1700 - SIGRAFLEX APX2 Hochdruck is a multilayer, high-strength gasket sealing sheet designed for high-temperature applications. The sheet is comprised of 0.020” thick layers of highly oxidation resistant SIGRAFLEX APX2 flexible graphite and 0.002” thick inserts of 316L stainless steel foil, manufactured with SIGRAFLEX Hochdruck technology.
SIGRAFLEX APX2 Hochdruck was created for end users in the process industry to cover a broad range of demanding gasket requirements with a reliable and safe product. It is specifically designed for high temperature flat gasket applications. Teadit GR1700 combines the outstanding characteristics of both SIGRAFLEX APX2 flexible graphite and reinforced sheets manufactured with SIGRAFLEX Hochdruck technology.
Gaskets made from GR1700 sheet perform particularly well in critical applications due to their high mechanical strength and the blow-out resistance, working pressure resistance up to 3600 psi (250 bar), excellent chemical resistance, very low cold or hot relaxation, and the maximum permissible gasket stress. GR 1700 sheet services a temperature range from -418°F (-250°C) to approximately 1202°F (650°C). Among its advantages, there is good conformation to the surface sealing, excellent torque retention and high sealability.
Gaskets fabricated from GR1700 sheet are suited for applications in the chemical, petrochemical, refining, power generation, pulp and paper, steel industries, as well as other critical processes. These gaskets are commonly used in pipe flanges, equipment and pressure vessels; non-typical geometry flanges tongue/groove and heat exchanger flanges. They are also suitable for use in the manufacture of gaskets for sight glass, pumps, fittings and valves, etc. Typical physical properties of GR 1700 sheet are shown in the table below:
