Plate HEAT EXCHANGER GASKET is one of the important parts of plate heat exchanger, a kind of ring which can produce plastic deformation and has a certain strength material. Most gaskets are cut from non-metallic plates, or by specialized factories in accordance with the required size, the materials are asbestos-rubber sheets, asbestos plates, polyethylene plates, etc., but also the use of thin metal plates (white iron, stainless steel) to the asbestos and other non-metallic materials made of metal clad gaskets; There is also a winding gasket made of thin steel straps and asbestos belts.
Common rubber gaskets are suitable for applications with temperatures below 120 ℃; asbestos-rubber gaskets are suitable for applications where water vapor temperature is less than 450 ℃, oil temperature is less than 350 ℃, pressure is less than 5MPa, for general corrosive media, the most commonly used acid-resistant asbestos plate. In high-pressure equipment and piping, the use of copper, Aluminum, no. 10th steel, stainless steel made of lens type or other shape of metal gasket. The contact width between the high pressure gasket and the sealing surface is very narrow (line contact), and the sealing surface and gasket are processed with high finish.
