Various materials and applications of plate heat exchanger gaskets_
Various materials and applications of 710 plate heat exchanger gaskets, plate heat exchanger gaskets are extremely critical components of plate heat exchangers, and the application range of plate heat exchangers is largely sealed The limitation of the gasket, in the strong corrosive medium, the requirements for the gasket are extremely high. The gasket of the plate heat exchanger is a circular ring made of a material that can produce plastic deformation and has a certain strength. It is a plate type. One of the important parts of the heat exchanger. Diguang independently develops and produces special sealing gaskets, and chooses different sealing gaskets according to different applicable media. The main types are nitrile rubber gasket (NBR), hydrogenated nitrile rubber gasket (HNBR), EPDM gasket (EPDM), solvent-based ethylene propylene rubber gasket (CE), general fluoro rubber gasket (GF) and special fluoro rubber gasket (AF), etc. The sealing gaskets of the plate heat exchanger have different types of rubber, and the adaptable temperature and medium parameters are all different. Nitrile rubber is generally suitable for non-polar media such as alkanes and olefins, light and heavy fuel oils, lubricating oil, animal and vegetable oils, hot water, salt water and other media with a temperature higher than -25 and lower than 120 degrees Celsius. EPDM rubber is mainly suitable for superheated water, water vapor, atmospheric ozone, non-petroleum-based lubricating oil, weak acids, weak bases, ketones, alcohols and other media with a temperature higher than -50 and lower than 150 degrees Celsius. Fluorine rubber is mainly suitable for non-polar mineral oils whose temperature is higher than 0 and lower than 180 degrees Celsius, such as pump oil, lubricating oil, etc., and can also be used for food oil.
