Graphite Gaskets Elasticity And High Strength

Flexible graphite composite gasket, Graphite Gaskets also known as enhanced graphite gasket or high-strength graphite gasket is made from the enhanced graphite plate perforated or cut, it has good corrosion resistance, high / low temperature, good compression resilience and high strength Sex

Enhanced graphite gasket commonly used in the inner layer of reinforced materials are ss304, ss316 or tinplate, etc., the thickness of 0.1 ~ 0.127mm, the form of a sponge board enhancement, stencil enhancement, plate enhancement. Commonly used materials for the 304 reinforced graphite, Graphite Gaskets can be made into a variety of circular geometric gasket is widely used in pipes, valves, pumps, pressure vessels, heat exchangers, condensers, generators, Graphite Gaskets air compressors, exhaust pipe , Refrigerators and so on. Graphite-reinforced gaskets can also be cut into complex gaskets, such as water level gauges, punching flange gaskets and automotive diesel engine cylinders.

High-strength graphite gasket according to the needs of the use can be processed into the following forms: 1. Basic graphite composite gasket 2. Package inside the graphite composite gasket 3. Graphite Gaskets Outside the package graphite composite gasket 4. Inner and outer edge of the graphite composite gasket. Graphite composite gasket package to maintain the original form of the original gasket of the excellent performance, Graphite Gaskets but also easy to install, disassembly, easy to damage, but also to prevent the erosion of the media on the gasket to improve the pressure. Common wrapping material is 304 or 316 stainless steel.

Graphite composite gasket maximum processing size: 20 ~ 5000mm; special specifications or various non-standard products can be developed according to customer requirements.

Graphite gaskets, also known as flexible graphite gaskets, Graphite Gaskets are perforated or cut from expanded graphite sheets. Due to the high purity of graphite, the expanded graphite gaskets have good high strength, compression resilience, chemical resistance, High / low temperature, the use of long life and other excellent performance.

In the petrochemical business unscheduled maintenance workload of 60-80% is used to repair the sealing device. With the development of modern industrial production, the industrial sector, Graphite Gaskets especially large-scale petrochemical enterprises, thermal power plants, nuclear power plants and other industrial enterprises on the performance of gasket set higher and higher requirements. Gas system is no exception, due to gas flammable, explosive and toxic characteristics make the gas system in which the use of gasket sealing requirements also put forward higher requirements.

Application of the earliest traditional sealing materials, including the general and oil-resistant two categories. Which is divided into high pressure, medium pressure and low pressure of various grades. Asbestos rubber sheet by the asbestos fiber, rubber and other filler material by mixing and heating and rolling, which also need to heat the vulcanization treatment. As the high strength of asbestos fiber, but also resistant to higher temperatures (asbestos temperature performance is usually within 480 ℃, higher than the temperature of the asbestos fiber within the crystal water will break down and lose strength), a wide range of materials, manufacturing easy to industrial Production, Graphite Gaskets according to the needs of the scene made in a variety of shapes and specifications of the gasket, the use of more convenient, cheap, therefore, has been widely used in traditional sealing material. However, this material sealing performance is not high (the sealing is usually about 1 × 10-2 ~ 1 x 10-3Cm3N / S or so), in particular, such components such as gasket rubber and other components susceptible to temperature and media (such as solvent ), Graphite Gaskets And in the use of stress relaxation is likely to occur, affecting its sealing performance and life, in addition to asbestos is recognized as carcinogens, from the seventies onwards, many countries in the world have gradually enacted the law Will be included in the scope of the ban, with the requirements of the equipment to improve the sealing and sealing technology development, asbestos rubber material has been gradually replaced by other new materials, the use is gradually reduced. Generally only used in the temperature, Graphite Gaskets the pressure is not high non-critical equipment occasions.

Polytetrafluoroethylene material has a very good chemical corrosion resistance and wide temperature characteristics, it can include acid, alkali, solvents and other chemical media corrosion, Graphite Gaskets the temperature can be from -250 ℃ ~ 10 250 ℃, and With the characteristics of clean and not pollution, so commonly used in chemical, food, medicine and other enterprises as a gasket, Graphite Gaskets but the biggest drawback of this material is its cold performance, even at room temperature, will be over time contact stress Reduced, that is prone to stress relaxation, thus affecting the gasket sealing life.
