GRAPHITE SEALING RINGS

详情

Profile rings, that are almost maintenancefree, for severe temperature changes and/or extreme temperatures, which cannot be handled with elastomeric O-rings. Grafopak Profile rings provide good deformability, permanent resilience, long-term flexibility and good structural strength. APPLICATION Pressed rings of expanded pure graphite for static sealing of machine parts in high temperature applications and with temperature cycles, ***** in heating and cooling systems, heat exchangers, valves or in pumps as seal for casing. DESIGN: Permanently elastic, expanded graphite ( > *9, 8% graphite) without binders or fillers. Temperature ***0~***0℃ Pressure *0Mpa Density 1.0~2.0g/cm3 Velocity 0~*5m/s PH range 0~*4 Size Ø5~Ø***0mm
