211 plate heat exchanger rubber pads play a relatively large role in plate heat exchangers. If there is no plate heat exchanger rubber pads, the equipment will not work. Today, I will give you an analysis of the importance of plate heat exchanger gaskets in plate heat exchangers? Plate heat exchanger gaskets are one of the important components of plate heat exchangers, which can produce plastic deformation and have a certain strength. Ring made of different materials. Most of the gaskets are cut from non-metallic plates or made by professional factories according to the specified size. The materials are asbestos rubber plates, asbestos plates, polyethylene plates, etc.; thin metal plates (white iron, stainless steel) are also used to remove asbestos A metal-wrapped gasket made of non-metallic materials; there is also a spiral wound gasket made of thin steel tape and asbestos tape. Ordinary rubber gaskets are suitable for occasions where the temperature is lower than 120°C; asbestos rubber gaskets are suitable for occasions where the temperature of water vapor is lower than 450°C, the temperature of oil is lower than 350°C, and the pressure is lower than 5MPa. It is generally corrosive The most commonly used medium is acid-resistant asbestos board. In high-pressure equipment and pipelines, metal gaskets of lens type or other shapes made of copper, aluminum, No. 10 steel, and stainless steel are used. The contact width between the high-pressure gasket and the sealing surface is very narrow (line contact), and the processing finish of the sealing surface and the gasket is relatively high. The rubber gasket is a very inconspicuous 'part' in the plate heat exchanger. Although it is small, its function is quite large. The important role of the plate heat exchanger rubber gasket in the operation of the equipment is recognized by everyone. If there is no plate type Heat exchanger rubber pad, then the equipment will not work. Heat exchanger rubber strips are divided into various materials according to different liquid media. The most commonly used lifting materials are EPDM and nitrile rubber pads. The rubber pads of these two materials have good water and oil resistance and high temperature resistance. It can reach 120°-150°. For the rubber pads of heat exchange equipment in the food industry, food-grade plate heat exchanger rubber strips can be used, such as silicone rubber and fluorine rubber with good acid resistance. However, the use of both rubber pads It is not a wide range, but it is a “part” with a strong application. Nowadays, heat exchanger gaskets with better water and temperature resistance are basically used in the industry to ensure the high quality of heat exchange equipment.
