Specification of Packing Gasket Donit Grafilit Em
GRAFILIT® EM is expanded graphite based material with expanded stainless steel insert, which enables applications with high operation pressures, including cycling operations. The surface pressure distribution on gaskets provides excellent thermomechanical properties and sealing characteristics, and increases blowout resistance. Therefore, materials are suitable for high temperature applications in petrochemical industry and steam supply.
COMPOSITION
Expanded natural graphite (> 99% graphite purity), expanded stainless steel sheet insert (AISI 316L; 0.15 mm).
PROPERTIES
Material with excellent media resistance and blowout safety, even in extreme loads, makes this material superior.
