Flexible Graphite Packing

1.Application:insulation sealing; 2.Packaging:sealed plastic bags and carton box.

Flexible Graphite Packing

1.Material:Braided by low-sulphur expanded graphite yarns,reinforced by cotton yarns,fiberglass,carbon fiber.

 

2.Application:Widely used in high temperature and high pressure environment. hydrogenation reactor, paper plant, power plant, oil refinery. And valve, pump, expansion joint, mixer, etc. which need to effective seal.

 

3.The advantages of materials:

MATERIALS	ADVANTAGES
low-sulphur expanded graphite yarns	with very low friction coefficient, not damage shaft and valve rod. With good heat conductivity and chemical resistance and high elasticity.
fiberglass	high strength,low cost.
carbon fiber	low ignition

 

 

 I. Definition:flexible graphite packing is waved by expanded graphite yarns, and it is weaved with different weaving technologies, usually, it is applied in many situations other than strong oxidant, it can be used to seal hot water, high temperature, high pressure steam, heat exchange agent, hydrogen, ammonia, organic solvent, hydrocarbon, low temperature liquid and other seal mediums. It is a unique new compressed seal packing.

 

II. Usage:it is used in the pump spindle, cylinder rod, valve rod, interface and other places easy for liquid leakage at the connections of centrifugal pump, reciprocating pump, valve, pipeline and other sections of petroleum, chemical industry, electric power, metallurgy, machinery, papermaking as well as other industries.
