Flexible Graphite ---Graphite Braided Packing
Flexible graphite braided packing is formed by braiding and shaping graphite yarn. Its resilient, compressible, thermally conductive and self-lubricating properties make it ideal for use in pumps and valves in petrochemical refining, power generation and other industries. It is suitable for the sealing of valves, pumps, and reactors etc, which work in the high temperature, high pressure and strong corrosive media. Specifications are 3x3-50x50mm.
Working Media
Hot water, steam, oils, acids, alkalis, ammonia, hydrogen, organic solvents, hydrocarbons, low temperature liquids, etc. Maximum Working Pressure: 30MPa. Working Temperature: -200 -650.
