1. Product Feature
This packing is braided from specially treated high-purity graphite yarns with sacrificial anode anti-corrosion additives(Zinc). It retains excellent sealing performance and temperature resistance of graphite, while effectively preventing electrochemical corrosion and pitting on valve stems and pump shafts through sacrificial anode protection, reducing shaft sleeve replacement cost and extending equipment service life.
2. Applicable Equipment
Specially designed for valves, pumps, pipeline flanges and sealing points in corrosive environments. Suitable for gate valves, globe valves, control valves, centrifugal pumps and systems where electrochemical corrosion protection is required.
