Graphite composite gaskets are corrosion resistant

- 2022-09-17-

Graphite composite gasket, also known as reinforced graphite gasket or high-strength graphite gasket, is a kind of gasket made of sprinted metal tooth plate or metal mesh plate and expanded graphite particles. It is usually stamped or cut from reinforced graphite sheet by gasket cutting equipment. The commonly used inner layer reinforcement materials for reinforced graphite gaskets are S304, S316 or tinplate and other materials.

The thickness is generally above 0.5mm~3mm, and there are sprint plate reinforced composite gaskets, mesh plate reinforced composite gaskets, and flat plate reinforced composite gaskets. Graphite composite gaskets can be made into various round and non-standard gaskets, such as flange gaskets, cylinder gaskets, exhaust pipe gaskets, ribbed heat exchanger gaskets, etc. .

According to the needs, high-strength graphite composite gaskets can be made into graphite composite gaskets with stainless steel edging. The commonly used edging materials for graphite composite gaskets are S304 or S316L stainless steel. Features: It has good corrosion resistance, high/low temperature resistance, radiation resistance, good compression resilience and high strength.

The required preload is smaller than that of metal gaskets and metal spiral wound gaskets, and the requirements for flange surfaces are not high. It is a relatively economical and practical gasket. If the edge wrapping method is adopted, the excellent functions of the original graphite composite gasket can be maintained, and it is easy to install and disassemble, and it is not easy to be damaged. pressure function.

Application equipment: sealing parts of flange connections such as pipes, valves, pumps, pressure vessels, heat exchangers, condensers, generators, air compressors, exhaust pipes, refrigerators, etc. can replace asbestos rubber gaskets and iron-clad gaskets piece. The maximum processing size of graphite composite gaskets is unlimited, and special standard or various non-standard products can be formulated according to customer requirements.
