| 867\868High Strength Graphite Gaskets:
1. Summary
867/868 High Strength Graphite Gaskets is a sort of advanced
sealing material of used or flange sealing. It is combined
organically together with metallic and nonmetallic materials
by using physical and chemical methods. Therefore it causes
that this sort of composite material gave prominence to
the advantages of the two sorts of materials, and overcome
materials in brand-new physical and chemical performances.
their drawbacks, being excellent than traditional
2. Characteristics
high strength graphite gasket has the characteristics as
follow
2.1 Good high and low temp-resisting, anti-corrosion, anti-
irradiating, anti-high-pressure performances. And it has
wide applicability.
2.2 Fine filling performance and plasticity. It needs not
high the precision of sealing surface and the pre-tight
stress is lesser.
2.3 It is easy to dismantle and is convenient to clean while
overhauling so that the intensity of labor is lightened
greatly.
2.4 Higher mechanical strength and excellent resiliency.
2.5 It is not aged. Its service life and storing period
are longer and can be used repeatedly.
2.6 Good impermeability.
2.7 It is simple for gasket manufacturing. It also can be
processed in the overhauling site. This is adaptive especially
to the deformed gasket.
2.8 It can replace the iron gasket, asbestos gasket, metallic
gasket, pure copper gasket as well as those sealing gaskets
manufacture with vegetable fiber mineral fibers and chemical
fiber, and it yet can compensate the defects of the gaskets
mentioned above.ed
3. Main Technical Parameters of the Product
Service pressure: ≤6.4MPa Service temperature: -200~650℃(oxidizing
