Calvo Sealing S.L. although having a wide range of plunger-stoppers, wants to go further and promotes a new gasket called ICP 9000MR. It is a perforated high quality expanded graphite sheet reinforced with several smooth stainless steel sheets of 0.05mm. The inclusion of this reinforced steel enables the gasket to have an excellent managing and mechanical resistance, so it is recommended for high temperatures and pressures sealing applications.
As well it is highly recommended for thermal and petrochemical plants since the gasket has an operating conditions of a minimum temperature of -210ºC and a maximum of 700ºC. Moreover it can takes pressures up to 650 bars.
