Expandable graphite packing is made of flexible graphite yarn through different weaving process. |
|
Advantages:
The product has excellent high temperature resistance, anti-chemical corrosive, lubrication and thermal conductivity, low friction coefficient, high strength and outstanding sealing performance. It is suitable for use in static packing sealing at high temperature. It can be treated with corrosion inhibitor according to corrosive environment and clients’ requirements in order to have better anti-corrosion.
Usage:
The product is suitable for use for almost all the media including hot water, high temperature high pressure vapor, oil, heat exchange liquid, acid, alkali, ammonia gas, hydrogen gas, organic solvent, hydrocarbon, low temperature liquid (excluding sulphuric acid and strong oxidant) etc., , and in industrial equipment and devices in petroleum, electric power generation, steel and iron, chemical, light industry, pharmaceutical, etc.
Specifications of Expandable graphite packing:3*3mm~60*60mm;Special specifications can be ordered on the customers' demands.
