High carbon packing made of high carbon fiber and graphite filled into material, adding lubricant. High carbonized fiber packing is manufactured by heating polyacrylonitrile fiber into carbonized fiber, which is then braided into packing after impregnation in PTFE dispersion. This high carbon packing has good heat conduction and low corrosion rate,and the price is relatively lower, so it’s generally used in dynamic sealing in the presence of weak acid or alkaline media, or media that contains few solid particle grains.
|Shaft speed||35m/s lubrication|
|25m/s dry running|
3,High and low temperature resistance,
Applicable to acid, strong corrosive, hot oil, solvent, boiler water supply equipment. Centrifugal pump, mixer, ball valve, valve, gate valve, plunger valve, oil off drilling tools.
Used for pump seals or valve seals in high pressure and high temperature. Handle water, steam, acids and aldalis for power stations, refineries, boiler plants etc.
