Flexible Graphite Ring ZW#3800
The graphite tapes, gasket, molded ring, and laminated sheets are made from flake (exfoliated) graphite with high carbon content which is gone through chemical treatment, expanding under high temperature and then machine compressing. It has the characteristics of high temperature resistance, corrosion resistance and good elasticity, and is the basic material for making all kinds of reinforced graphite sheets, graphite ring tapes, packing ring and sealing gaskets. Working temperature –200 to 450℃ (in air), up to 650℃ (in reducing atmosphere), Service pressure is 150 bar maximum. The graphite ring is applicable to compressors, pumps, valves, chemical equipment and instruments…etc. The applicable fluid including water, high temperature, high pressure steam, heat exchange liquid, ammonia, hydrogen, organic solvents, hydrocarbons, cryogenic fluids. Certain categories are reinforced with flat or tang stainless steel / Nickel inserts which enhance mechanical properties of the gasket. It is extremely conformable to suit either worn or pitted flange.
