This type of gasket uses asbestos as a filler and has a wide range of uses, such as pipeline flanges, pressure vessels, heat exchangers and various valve covers.
The maximum working pressure can reach 42.0MPa.
The maximum operating temperature can reach 600°C.

Due to the use of non-asbestos as the filler, in addition to heat resistance, other properties are the same as asbestos gaskets, and the design and use conditions are the same as asbestos. It is a static sealing element for flange connections such as pipes, heat exchangers, and towers. Used in petroleum, chemical, electric power, shipbuilding, steel and other sectors.

PTFE has strong corrosion resistance. For example, it can be used in corrosive vacuum piping if it is combined with strong corrosion resistance metals such as Monel, titanium, and nickel. It is a static sealing element at the flange joints of pipelines, heat exchangers, towers, etc., and is widely used in petroleum, chemical, electric power, shipbuilding, steel and other sectors. It is especially suitable for corrosion resistance and sealing of vacuum parts.

Expanded graphite has the advantages of high temperature resistance, corrosion resistance, flexibility and good resilience. In the spiral wound gasket series, its service temperature is relatively high. It is most suitable for use in occasions where the temperature changes. It is a static sealing element at the flange connection of pipelines, heat exchangers, tower tanks, etc., and is widely used in petroleum, chemical, electric power, shipbuilding, steel and other sectors. It is especially suitable for high temperature and high pressure steam, LPG, and alternating hot and cold temperature differences.
Maximum operating temperature: oxidizing gas: 450°C; non-oxidizing gas: 800°C.
