Graphite gaskets that made by pure graphite plate or metal (teeth plate, plate, net) reinforced graphite plate cutting or stamping, has many excellent sealing performance, such as: thermal stability, self lubrication, corrosion resistance, aging, not brittle, etc., in the harsh conditions of the conditions can be used for a long time, very few need to maintain. Lining material can be different with different metal plate. Type optional without edge, inner edge, out sourcing side, inside and outside wrapping. Graphite cut gasket is from pure graphite plate punching or cutting into the, it has good corrosion resistance, resistant high / low temperature, good compression elasticity and high strength, a variety of circular complex geometric gasket is widely used in pipes, valves, pumps, pressure vessels, heat exchanger, condenser and generator, air compressor, exhaust pipe, a refrigerating machine.
Expandable graphite (flexible graphite) is made from pure natural graphite by chemical treatment and high temperature of 1000. This material provides excellent heat resistance and chemical resistance. It can be very good to make gasket with high elasticity and low ductility.
1, flexible graphite gasket in the extremely low temperature to 400 degrees within the high temperature range of sealing performance almost unchanged;
2, flexible graphite gasket almost all of the liquid has excellent chemical resistance (except for the strong oxidizing acid, etc.);
3, due to the cold deformation and ductility is very small, tight installation has no effect on the flexible graphite gasket.
Graphite gasket classification
Flexible graphite gaskets are made of flexible graphite sheets (or metal reinforcing), and are divided into four types according to the application requirements:
1, flexible graphite gasket: cutting from the flexible graphite sheet, used for pipe flange and valve cover, etc.. It is recommended that the gasket is a small diameter washer, which depends on its low mechanical strength.
2, flexible graphite gasket Mi: the hook of the steel sheet (0.2 mm thick) by a flexible graphite sheet is clamped in the middle, and then is cut into a certain size, mechanical strength is very high.
3, flexible graphite gasket PM: flexible graphite sheet is adhered to the 0.2 mm thick 304 stainless steel sheet with high mechanical strength and easy to transport, because it can also be cut into a complex shape, this gasket is widely used in various industries.
4, flexible graphite gasket PM-A: the T/#1215 stainless steel sheet for 316 steel (50 micron).
Pipe flanges for all kinds of industries, heat exchangers, valve covers, etc., as well as the special shape of the level gauge, the flange.
Graphite gasket to stone line materials, warp knitting and shaping. Graphite gasket used for high temperature, high pressure, strong corrosive medium under the work of all kinds of valves, pumps, reaction kettle and other equipment of the stuffing box sealing.
