Detailed product description
Graphite packing ring
-content of graphite: at least 99%
-can be reinforced by 304ss , nickle wire
-content of wire mesh:60%
Graphite packing ring, graphite gasket is formed by molding flexible graphite tape or flexible graphite braided packing, and metal materials can also be put in together. It is mainly used for sealing or valves, pumps and expansion joints, which are used in oil industry, thermoelectric station, nuclear power station and other general industries. The property solves the problemof corrosion to the valve stem completely.
Typical types
Available in 99% purity, corrosion inhibited and oxidation resistant grades.
Supplied endless, split or as matched halves.
Square or rectangular section rings supplied as standard
Non-standard shapes can be producedto suit specific requirements.
Metal tipped rings available for high pressure anti extrusion applications.
Graphite packing sleeves with or without stainless steel eyelets are available.
Typical applications
Packing for dynamic sealing of compressors and pumps.
Packing for valves.
Packing for the gland boxes of chemical instruments.
Available in almost every style of our braided packing.
For composite sealing to take the place of mechanical sealing.

Construction:
Zt-410(graphite sheet jacketet tanged metal) is made by materials of three cascades. A laminated graphite is inserted into a convexo-plane metal frame perforated. It is produced by specially pressing and sticking process. This kind of sheet is be seized of the characteristics such as good compressibility and resilience, small stress relaxation, fine compensation function for uneveness of sealing surfaces and long working life.

Description:zt-600 spiral-wound gasket is formed of v-shaped metallic stripe and soft non-metallic filler by means of piled, spiral wound and connected its end and beginning by dot welded. Depend on its excellent compression resilience it is suitable for sealing spots where the alteration of temperature and pressure are frequent. It can be used as the static sealing element of pipe, valve, pump, thermal exchange, condensing tower, plain hole and man hole of flange, etc. It has been widely applied in the fields of petrochemical, mechanical manufactory, power station, metallurgy, shipbuilding, medical and pharmaceutical nuclear power station and navigation, etc.
Application:
We can produce according to asme, bs, jis and en(din) standards or client request.
