Sigraflex® Graphite HD

Sigraflex® Graphite HD is a high-pressure graphite sheet with multiple inlays of 0,05 mm thick stainless steel foil. The material is often applied as flange seals for pipes and equipment. Ridderflex produces amongst others flange gaskets out of this graphite sheet. We always have an ample stock of this sheeting material. 

Properties of Sigraflex® Graphite HD

Sigraflex® graphite sheet is very good pressure resistant and has a high temperature resistance. The material is also non-sticking. These properties, along with the good chemical resistance, make the material perfectly suitable for application in steam systems in amongst others the process industry and the (petro)chemical industry.
