Graphite Gaskets High Strength

The flexible graphite gasket is made of perforated or cut from a pure graphite plate. It has good corrosion resistance, high / low temperature resistance, good compression resilience and high strength, and various rounds of complex Geometric gaskets are widely used in pipes, valves, pumps, pressure vessels, heat exchangers, Graphite Gaskets condensers, generators, air compressors, exhaust pipes, refrigerators and so on.

Expandable graphite (flexible graphite) from pure natural graphite through chemical treatment and 1000 ℃ high temperature treatment, this material provides excellent heat resistance and chemical resistance, can make the gasket with high elasticity and low ductility feature.

1, flexible graphite gasket in the very low temperature to 400 ℃ high temperature range of sealing performance is almost unchanged

2, flexible graphite gasket almost all of the liquid has excellent chemical resistance (except for strong oxidizing acid

3, due to cold deformation and ductility is very small, too tight installation of flexible graphite gasket has no effect.

1, no radiation without pollution. Flexible graphite does not contain harmful ingredients to the human body, and asbestos products have radiation hazards, and also pollute the environment.

2, high temperature. Flexible graphite reinforced composite gasket can withstand 1650 ℃ high temperature, even if the chemical equipment melting, it is still safe and sound. Graphite Gaskets And asbestos products at 500 ℃ when the internal crystallization of water will break down, so that their own powder, loss of efficacy.

3, for a wide range of applications. Flexible graphite in addition to strong oxidizing acid, the ability and most of the chemical medium, including for radioactive chemical media, and asbestos products, poor adaptability, can not be used for radioactive media. Some chemical tower, heat exchanger, etc., require the connection parts are not insulated, flexible graphite can do, stone products can not.

4, easy to use. Flexible graphite gasket coefficient is only half of the asbestos products, that is, to achieve the same sealing effect, tighten the power of the screw can be much smaller. Graphite Gaskets In addition to the above-mentioned obvious characteristics, flexible graphite has the characteristics of excellent sealing performance, good compressibility, good elasticity and oxidation resistance, and has strong self-lubricating property and plasticity, and has good electrical conductivity, specific gravity and high density. Characteristics, can produce a variety of adjustment of diesel engines, compressors and other types of pipes, Graphite Gaskets flange gaskets and so on.

1, flexible graphite gasket: from the flexible graphite sheet cut from the pipe flange and valve cover and so on. It is recommended that this gasket be a small diameter gasket, depending on its low mechanical strength.

2, flexible graphite gasket MI: hooked carbon steel sheet (0.2 mm thick) is placed in the middle of the flexible graphite sheet, and then cut into a specific size, high mechanical strength.

3, flexible graphite gasket PM: flexible graphite sheet is attached to the 0.2 mm thick 304 stainless steel sheet on both sides, with high mechanical strength and easy to transport, Graphite Gaskets because it can also be cut into a complex shape, this gasket Is widely used in various industries.

4, flexible graphite gasket PM-A: T / # 1215 stainless steel sheet replaced with 316 steel (50 microns).
