Does the graphite metal pad have any requirements on the sealing surface?
The graphite composite gasket can be processed into the following forms according to the needs of use: 1. basic graphite composite gasket, 2. package inner graphite composite gasket, 3. outer graphite composite gasket 4., inner and outer edge graphite composite gasket. The graphite composite gasket has the advantages of keeping the excellent performance of the original gasket, easy installation and disassembly, uneasy damage, and preventing the medium from eroding the gasket and improving the pressure resistance. Commonly used wrapping material is 304 or 316 stainless steel.
Graphite gasket:Graphite composite gasket commonly used internal reinforcement materials are SS304, SS316 or tinplate, etc., the thickness of 0.1~0.127mm, in the form of dash plate enhancement, mesh enhancement, plate enhancement. The commonly used material for the 304 reinforced graphite can be made into a circular geometry gasket is widely used in all kinds of pipes, valves, pumps, pressure vessels, heat exchanger, condenser, generator, air compressor, exhaust pipe, refrigerator etc.. Graphite reinforced gaskets can also be cut into complex gaskets such as water level gauges, gaskets, punching flanges, gaskets, and cylinder gaskets for automotive diesel engines.
Metal wound gasket:Metal wound gasket is a sealing gasket is used widely at present, in order to return to the best elastic gasket semi metallic gasket, by V or W shaped steel strips with various fillers alternately wound together, high temperature, high pressure and adapt to the use of ultra low temperature or under vacuum conditions, by changing the gasket combination of materials, can solve the problem of all kinds of chemical corrosion medium on the gasket, the structure density can according to different requirements to lock force production, in order to strengthen the body and accurate positioning, the gasket ring and the outer ring is provided with positioning reinforced metal, using internal and external steel ring to control the maximum compaction degree, the sealing surface precision requirement is not high the surface of the flange gasket contact.
