China products graphite ring Characters:

High-temperature, high-pressure graphite packing set is corrosion-inhibition type expanded graphite packing set. Add corrosion inhibitor to protect valve shaft and filling. If used in hydrogenation plant, paper-making industry, power plant and refining industry, it can get effective sealing effect. It holds the advantages of good self-lubricating performance, heat exchange, small friction factor, strong universality, good flexibility, high strength and protecting shafts.

Equipment: universal packing set Industry: Petroleum equipment, power plant, chemical industry and steel plant are recommended to use. Medium: hot water, high temperature, high pressure steam, heat exchange medium, ammonia, hydrogen, organic solvent, hydrocarbon, low-temperature liquid and so on
