Graphite seals - 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.

The range in the graphite seals segment is not limited to rings and tapes, but also includes sheets: The many advantages of billi graphite sheets include the low permeability of liquids and gases as well as high resistance to chemical substances. In addition, the plates made of natural graphite convince for their enormous stability and high resistance to temperature fluctuations. The graphite sheets can be ordered in different versions so that the perfect items are available for every application: For example, you can choose from models without steel reinforcement, with plain steel inserts and tanged stainless steel reinforcement. All graphite gaskets from our company are convenient for the targeted interaction between a high quality standard and improved health protection: you can order asbestos-free graphite sheets and many other types directly from us at a reasonable price.

Levelflex FMP54 for continuous level measurement in liquids under extreme conditions. The process connection with its ceramic-graphite seal safeguards high temperature and high pressure applications as they occur in steam boilers and toxic media like ammonia. The gas tight feedthrough guarantees additional safety. Only the gas phase compensation of the FMP54 gives reliable results in case of gas and steam phases. Reliable measurement in case of moving surface and foam or in changing medias.
