It is cut or punched by pure graphite sheet or metal (truss plate, flat plate, net) reinforced graphite sheet, with mass of excellent sealing performance, e.g.: thermal stability, self-lubricating, no aging, non-fragility, etc. Under extreme conditions, it can be stably and long-term used, extremely needing no maintenance. The lining material can choose different metal thin sheet. The model can choose without tipping, inner tipping, outer tipping, and inner-outer tipping. Type Cross section Tanged composite Plain composite Service range: It can be cut into gaskets in kinds of shapes, which is widely used for the container, boiler, pipeline, and pump, valve and flange, in petrochemical and mining industry, suitable for steam, mineral oil, transformer oil, hydraulic oil, fuel, water, and sea water, etc. Type 430 Compressibility 15~35% Recovery ≥20% Pressure 300bar Graphite Density g/cm3 1.0 Operating Temperature 0C -200~850 PH Value 0~14 Graphite Grade: Item Density Tolerance C≥% Tensile Strength Sulfur Content Chlorine Content Stress Relaxation Loss on Ignition Industrial grade ±0.06 g/cm3 98 4 Mpa <1000ppm <50ppm 10% 2.0≤%
