| Both carbon fibre PTFE and the compound material
sealing packing ring developed are characterized
by their advanced construction, high quality of
hermetic property, high strength of anti-pressure,
high resilience, corrosion-resistance, good heat
conduction, radiation-resistance and durance.
Their sevice life of moving-sealing can be as
long as 6500 hour whild the life of static-sealing
is much longer. When load changes and sudden cold
or hot occurs, the function of sealing can be
retained and the leakage and dripping problems
of oil refining will be solved.
Because of no corrosive matters to metal, the
small frictional coefficient and the self-lubrication,
the materials will not ruby against mechinery
axises. They are widely used for circle and static
sealing packing charges in various pipes, valves,
pumps, reactive installment, hydraulic pressure
machines and transport instruments for oil industry,
chemical industry, electric mechinetry making,
light textile, metallurgical and militrary industry,
and become one of the advanced compressed sealing
materials in the world. |
