Expanded graphite packing lines from the low sulfur expanded graphite braided, lined cotton yarn increased. Has an extremely low coefficient of friction, will not wear the shaft and stem, and has good thermal conductivity, chemical resistance and high resilience. Also available on request the following reinforcements: glass fiber ------- high strength, low-cost; carbon fiber ------- fever loss. PK 2000K-inhibitor type expansion graphite packing as the sacrificial anode corrosion inhibitor added to protect the valve stem and packing. Application: Widely used in high temperature, high pressure hydrogenation unit harsh operating conditions, the paper industry, power plants, refineries and other needs effectively sealed valves, pumps, expansion joints, mixers, blenders and so on.
