Flexible graphite gasket

  Flexible graphite gasket is from pure graphite plate drilling or cutting and it has good corrosion resistance, high / low temperature, compression elasticity and high strength good, complex geometric gasket circular is widely used in all kinds of pipes, valves, pumps, pressure vessels, heat exchanger, and condenser generator, air compressor, exhaust pipe, refrigerator etc..

  Overview of flexible graphite gaskets

  Flexible graphite gasket is from pure graphite plate drilling or cutting and it has good corrosion resistance, high / low temperature, compression elasticity and high strength good, complex geometric gasket circular is widely used in all kinds of pipes, valves, pumps, pressure vessels, heat exchanger, and condenser generator, air compressor, exhaust pipe, refrigerator etc..

  Characteristics of flexible graphite gasket

  Flexible graphite, also known as expanded graphite, is used as raw material in the process of chemical treatment. Under the high temperature of 800-1000, the compound layer turns into gas, which causes the scale graphite to expand about two hundred times, and it becomes the heat conduction of cotton, and overcomes the disadvantages of brittleness. Loose and porous, elastic. In the high temperature, high pressure or radiation conditions, the work does not occur decomposition, deformation or aging, chemical stability. The birth of flexible graphite, the traditional chemical seal area declared the end of time. Compared with asbestos gasket, flexible graphite has the following obvious advantages:

  1- no radiation, no pollution. Flexible graphite does not contain harmful ingredients to the human body, and asbestos products with radiation hazards, and will pollute the environment.

  2, resistant to high temperature. Flexible graphite composite gasket can enhance high temperature of 1650 DEG C, even if the chemical equipment melted, it is still safe and sound. And asbestos products at 500 degrees inside the crystallization of the water will be broken down, so that their own powder, loss of efficacy.

  3, a wide range of application. Flexible graphite in addition to strong oxidizing acids, ability and most of the chemical medium, including for radioactive chemical medium, and asbestos product adaptability is poor, can not be used for radioactive medium. Some chemical tower, heat exchanger and so on, the requirements of the connection parts are not insulated, flexible graphite can do, the stone products can not be.

  4, the use of simple and quick. Half coefficient of flexible graphite gasket asbestos products only, that is, to achieve the same sealing effect, tighten the screws strength can be much smaller. Flexible graphite in addition to the above obvious characteristics, but also has excellent sealing performance, compression, and characteristics of good elasticity, oxidation resistance, self lubrication and strong plasticity, and has good electrical conductivity, density ratio, etc., can produce all kinds of adjustment of diesel engine and compressor etc. all kinds of pipeline the flange gasket, etc..
