Graphite ring can be changed according to the need to use different physical and chemical indicators of graphite materials, carbon-graphite valve ring has the characteristics of other metal materials can not be replaced, so it is widely used in industry.Graphite ring all kinds of corrosive chemical liquids, strong alkali, hydrochloric acid, sulfuric acid and other strong corrosive liquids, organic solvents, liquid oxygen, etc., used in petroleum, chemical industry, chemical fiber, coal mining, power generation, metallurgy and other industrial fields of flange, valve, reactor, pump sealing.
Properties and characteristics of graphite ring: graphite ring self lubricity, high rebound coefficient of graphite ring, graphite ring good high temperature resistance.
