Stainless steel spiral wound graphite gasket is made of stainless steel wire and flexible graphite, the inner and outer ring are steel rings, reasonable design structure, standard manufacture, it has good sealing performance and compression resilience, it adapts to the corrosive medium in high temperature, high pressure, cryogenic, vacuum and operation parameter change sharply, it can be used in the LPG storage and distribution station, oil, chemical industry, oil refining, tank top into the hole.

　　There are four forms for stainless steel spiral wound graphite gasket : basic type, with the inner ring type, outer ring type, with the inner and outer ring type.

　　The internal reinforcement materials commonly used in the stainless steel spiral wound graphite gasket are SS304, SS316 or tinplate, thickness of 0.1~0.127mm, the forms are sprint plate, halftone plate, plain plate reinforced. The common material is the 304 reinforced graphite it can be made into the circular or geometry gasket and widely used in all kinds of pipes, valves, pumps, pressure vessels, heat exchanger, condenser, generator, air compressor, exhaust pipe, refrigerator etc.. The graphite gasket can also be cut into complex shapes such as water level gauge gasket, punching flange gasket and automotive diesel engine cylinder gasket.

　　The stainless steel spiral wound graphite gasket can be processed into the following forms according to the applications: basic type graphite composite gasket, wrapping inner edge graphite composite gasket, graphite composite gasket with wrapping outside edge and wrapping inside and outside edge graphite composite gasket. Graphite composite gasket in the form of the original gasket to maintain the excellent performance, but also easy to install and disassemble, not easy to damage, but also can prevent the erosion of the media on the gasket, improve the pressure. The commonly used wrapping material is 304 or 316 stainless steel.

　　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..

　　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.

　　raw material

　　. expandable graphite (flexible graphite) produced by chemical treatment and 1000 DEG C high temperature treatment of pure natural graphite, this material provides excellent heat resistance and chemical resistance, good pad with high elasticity and low ductility characteristics.

　　Second, characteristics: 1, in the extremely low temperature to 400 DEG C temperature range of sealing performance remained almost unchanged 2, almost of all of the liquid has excellent chemical resistance, strong oxidizing acids except) 3, as a result of the cold deformation and ductility is very small, install tight gasket has no effect.

　　type

　　Flexible graphite gaskets are made of flexible graphite sheets (or with metal reinforcement), and are divided into four types according to the application needs:

　　1, flexible graphite gasket: cut from the flexible graphite sheet, for the pipe flange and valve cover, etc.. It is recommended that the gasket is a small diameter gasket, 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, a flexible graphite gasket PM: flexible graphite sheet is adhered on both sides of the 0.2 mm thick 304 stainless steel sheet, with high mechanical strength and easy to transport, because it can be cut into complex shapes, the gasket is a wide range of applications in various industries.

　　。

　　4, flexible graphite gasket PM-A: the T/#1215 stainless steel sheet for 316 steel (50 microns). Four, application: used for all kinds of industrial pipe flange, heat exchanger, valve cover, etc., as well as the liquid level gauge, the level of the special shape of the flange.

　　Graphite gasket to stone line as the material, by weaving and shaping. Graphite gasket is suitable for high temperature, high pressure, strong corrosive medium under the work of all kinds of valves, pumps, reaction vessels and other equipment packing seal.

　　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.

　　Graphite gaskets are sealed gasket series.
