Graphite gaskets - Import export

Graf-Flex-SP2 seals The Graf-Flex-SP-2 seal is a pointed sheet seal produced by a special process. The design of the seal is based on empirical values. Numerous tests have been carried out to verify the adhesion between the pointed sheet and the graphite coating as well as the surface quality, and thus the adhesion between the coating and the flange surface.The first phase of these tests led to special perforation of the carrier plate in terms of the geometric shape of the hole and hole distribution. The second phase took account of the adhesion of the seal to the surface of the flange and defined the surface quality of the graphite material. The values found in this way were transferred to the mass production process using a special procedure. . This consisted of a specially produced perforated roller for penetrating the sheet together with a special surface roller. Finally, the graphite coating is applied to the defined surface in the calendering process.
