Reinforced graphite sheet
Graphite composite panels
YY-SM1004 graphite composite panels, also known as high-strength graphite reinforced graphite sheet or plate is made of metal teeth sprint plate or metal plate or sheet metal flat and pure graphite composite roll made of a sealing material. Graphite composite plate inner reinforcing materials commonly used in ss304, ss316L or tinplate thickness 0.05 ~ 0.2mm, generally in the form of composite reinforced sprint plate, stencil composite reinforced, flat composite reinforced several. It has a thermal stability, high strength and no cold flow characteristics, can be made into a variety of complex geometric shapes round and gaskets such as water gauge gasket, head gasket, exhaust pipe gaskets with ribs exchanger gasket is widely used.
Features: It has good corrosion resistance, high / low temperature, radiation-resistant, good compression resilient and high strength required preload than metal gaskets and spiral wound gasket is smaller flange less demanding side, is a more cost-effective sealing material.
Use the media: acids, bases, steam, solvents and oil and so on.
Application: sealing parts of pipes, valves, pumps, pressure vessels, heat exchangers, condensers, generators, air compressors, exhaust pipes, refrigerator and other flange can replace asbestos and non-asbestos rubber seal materials.
Common specifications: 1500mm * 1500mm, 1000mm * 1000mm thickness 0.8mm-5.0mm, may require special specifications.
Technical standards:
Can provide any standard and non-standard sizes, including ASME, DIN, JIS, GB and other standards. Available round, square and other profiled shapes, sizes and provide customized products according to need.
