Flexible graphite gaskets are perforated or cut from pure graphite sheets. They have excellent corrosion resistance, high/low temperature resistance, excellent shrinkage resilience and high strength, and a wide round of messy geometric mats. Sheets are widely used in pipes, valves, pumps, pressure vessels, heat exchangers, condensers, generators, air compressors, exhaust pipes, refrigerators, etc.

Overview and features

Flexible graphite, also known as swelled graphite, is made of squamous graphite and chemically treated to form interlaminar compounds. At a high temperature of 800-1000 ° C, the interlayer compound becomes a gas, which makes the scale graphite swell up to about 200 times, and becomes like heat conduction of cotton, and overcomes the brittle defect, thereby exhibiting excellent sealing property. Loose and porous, with elasticity. Work under high temperature, high pressure or radiation conditions, without differentiation, deformation or aging, and chemical stability. The birth of flexible graphite declares that the ancient era in the field of chemical sealing will be completed. Flexible graphite has the following distinct advantages over asbestos gaskets:

First, no radiation and no pollution. Flexible graphite does not contain harmful ingredients, while asbestos products are harmful to the human body and can also pollute the environment.

Second, high temperature resistance. The flexible graphite reinforced composite gasket has a high temperature of 1650 ° C, and even if the chemical equipment melts, it is still safe. When the asbestos product is at 500 ° C, the internal crystal water will be differentiated, so that it will be powdered and lose its effectiveness.

Third, a wide range of applications. In addition to strong oxidizing acids, flexible graphite contains most of the chemical media used in radioactive chemical media, while asbestos products have poor adaptability and cannot be used in radioactive media. Some chemical towers, heat exchangers, etc., require that the joints are not insulated, flexible graphite can be done, and slate products cannot.

High-strength graphite composite gaskets and flexible graphite gaskets Different graphite cutting gaskets are perforated or cut from pure graphite sheets. They have excellent corrosion resistance, high/low temperature resistance, excellent compaction resilience and high Strength, a wide range of chaotic geometric gaskets are widely used in pipes, valves, pumps, pressure vessels, heat exchangers, condensers, generators, air compressors, exhaust pipes, refrigerators, etc.
