The SIGRAFLEX HOCHDRUCK sealing sheet is rated to 250 bar (3,625 psi). It thereby meets the highest demands for sealability, making gaskets extremely safe and reliable. This is possible due to our unique HOCHDRUCK technology, creating a high-strength, adhesive-free layer composite of graphite and stainless steel foils.
The sheet is also available in a TA Luft compliant PRO version or made with SIGRAFLEX APX2 foil for high-temperature processes.
Both gaskets sheets – SIGRAFLEX HOCHDRUCK and HOCHDRUCK PRO – are PFAs-free and equipped with an antistick impregnation for reduced leakage and improved handling.
SIGRAFLEX HOCHDRUCK, technical data sheet
SIGRAFLEX BTCSS allows end users in the chemical, petrochemical and refinery industries as well as of power generation plants to seal their pipework and vessels safely and reliably with PFAS-free gaskets.
BTCSS flat gaskets are available as one-piece gasket designs up to an outside diameter of 1509 mm (59.4"). For larger diameters, for example two-layer gasket structures with segmented sections and staggered joints are recommended.
Refinery operators benefit from the use of packings made of high quality and high-purity oxidation resistant yarns from SGL Carbon. They offer a unique combination of tightness and heat dissipation, excellent high-temperature and chemical resistance, as well as reduced contamination of processes due to the high purity of the yarns.
SIGRAFLEX flexible graphite products made from expanded natural graphite and SIGRAFLEX yarn products are characterized by their high standard of quality. The proven quality of our materials considerably enhances process reliability in the petrochemical industry.
