The chemical industry is expert in using diverse manufacturing processes to transform natural re-sources into products and materials that deliver better solutions for customers and consumers. Its cur-rent challenge is the development of sustainable energy resources and raw material supplies. Sealing solutions must reliably meet the varied and growing requirements of the chemical industry. Process efficiency and dependable plant availability are just as important as sustainability and safety. Gaskets from our Advanced Solutions portfolio have been developed precisely for this purpose. They combine proven standards and innovative technologies while allowing a high level of flexibility.
The high-performance LE-SAFE gaskets have a metallic carrier and a soft layer of expanded pure graphite. Both components are held together by an adhesive-free bond, which is unlike conventional semi-metallic gaskets. This new technology was developed to minimize the risks adhesives pose to plant safety. For use in oxygen-carrying equipment and components, we follow a defined O2-Clean process. In our production process we only use graphite materials from individual batches that have been tested by the German Federal Institute for Materials Research and Testing [BAM]. In our clean-room facility, we check for contamination under strictly controlled environmental conditions. The prod-ucts then undergo cleaning, final inspection, and packaging, with O2-usage clearly marked on very single package. This eliminates and reduces contamination while significantly reducing the risk of un-expected fires and ensuring the complete traceability of the products.
Operating Data Information
The pressure specifications are to be seen as orientation values. It is advisable to verify the functionality of the flange connection by means of mathematical proof, e.g.: according to DIN EN 1591-1.
Semi-metallic gasket combinations can generally be used up to 450 °C without any problems. At temperatures >450°C, however, the combustion of the graphite accelerates exponentially. They can usu-ally be used up to 550 °C, but we then recommend consulting your gasket manufacturer.
