Graphite Tape For Spiral Wound Gasket
Description
Graphite tape is made by We use the high precision CNC lathe to cut the graphite coil into strip.Compared with the traditional graphite technology，it has higher precision, low damage and higher smoothness.
Application
Graphite tape as the filler for spiral wound gasket,In-situ pump and valve gland packing, manufacture of graphite packing rings. It is suitable for hot water, high temperature and high pressure condition, steam, heat transfer medium, ammonia, hydrogen, organic solvents, hydrocarbons, low temperature liquids, etc
