Type, logo and selection of flange gaskets!
Jun 09, 2018
The plain gaskets used in industry are generally made up of sealing elements and internal and external strong rings. Sealing elements or gasket bodies are the key parts to prevent leakage. Its commonly used materials are non-metallic materials, such as flexible graphite, polytetrafluoroethylene, fiber reinforced rubber based composite panels, etc. In addition, the sealing element material can also be rigid or flexible metal, usually used for high pressure and high temperature occasions.
Sealing elements for non-metallic materials are usually reinforced by inserting metal materials, and also facilitate the manufacturing of sealing elements such as graphite and other fragile materials. The reinforced material may be a metal sheet or a wire mesh. A sheet metal plate is often used in a sprint hole to increase the effect and increase the elasticity, and it is fitted together by a binder and a roller. The sealing element can also be provided with a surface layer or an anti adhesive treatment layer to increase the sealing effect and prevent the sealing surface of the flange from sticking.
