They are a kind of circular ring made of a material that can produce plastic deformation and has a certain strength. Most gaskets are cut from non-metallic plates or made by professional factories according to specified sizes. Their materials are asbestos rubber sheets, asbestos sheets, polyethylene sheets, etc. There are also metal-clad gaskets made by wrapping asbestos and other non-metallic materials with thin metal plates (tinplate, stainless steel); there are also spiral-wound gaskets made by winding thin steel strips and asbestos strips together. However, the current plate heat exchanger sealing gaskets have low corrosion resistance during use. At the same time, since the plate heat exchanger sealing gaskets are all large sheets, if there is a leak in special locations, such as the gasket at the water outlet, the entire plate heat exchanger sealing gasket needs to be replaced, resulting in a waste of resources.
