What Types of Pipe Flange Gaskets Are There

There are many types of pipe flange gaskets, which play an important role in various industrial applications, especially in the fields of petroleum, chemical, electric power, metallurgy, shipbuilding, papermaking and medicine. The following are several common types of pipe flange gaskets and their characteristics:

Rubber flange gasket

Rubber flange gasket is a commonly used pipeline connection sealing material with good sealing and corrosion resistance. Common rubber flange gasket materials include butyl rubber, chloroprene rubber, EPDM rubber, etc. Different materials are suitable for different media and working environments.

Metal flange gasket

Metal flange gasket is a pipeline connection sealing material made of metal material with good pressure resistance and temperature resistance. Common metal flange gasket materials include stainless steel, copper, aluminum, etc. Its sealing performance can be achieved by adjusting the pressure and surface flatness.

PTFE flange gasket

PTFE flange gasket is a pipeline connection sealing material made of polytetrafluoroethylene material with good corrosion resistance and temperature resistance. It also has excellent non-stickiness and insulation properties, suitable for various media and working environments.

Cellulose flange gasket

Cellulose flange gasket is a pipe connection sealing material made of materials such as cellulose and resin, which has good pressure resistance and temperature resistance. Common cellulose flange gasket materials include asbestos, asbestos-free, graphite, etc. Different materials are suitable for different media and working environments.

Summary

In short, there are many types of pipe flange gaskets, and suitable flange, sealing materials and flange supplier should be selected according to actual conditions. The selection of these gaskets depends on the corrosiveness, temperature, pressure of the medium transported by the pipeline, and the form of the flange sealing surface. The correct selection of gaskets is the key to ensuring that the flange connection does not leak. During use, attention should be paid to factors such as the material's pressure resistance, temperature resistance, corrosion resistance, and surface flatness to ensure the sealing and safety of the pipeline connection.
