Expanded graphite packing is braided by expanded graphite yarns, and it is braided with different 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.

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.
