The service life of different types of Plate Heat Exchanger Gaskets varies greatly due to the influence of materials, use environment, working conditions, etc.
Rubber gaskets are common types. For example, nitrile rubber gaskets have good oil resistance. In an ordinary oil or water medium environment with a temperature not exceeding 120°C and no strong corrosive media, they can be maintained for 2-3 years under normal use; but if the medium is highly corrosive, the service life may be shortened to 1 year or even shorter.
EPDM rubber gaskets have good weather resistance and chemical corrosion resistance. They can be used for 3-5 years under conditions with temperatures below 150°C and corrosive media such as acids and alkalis. Polytetrafluoroethylene gaskets have extremely strong chemical stability and outstanding high and low temperature resistance. Even in harsh environments with a high temperature of 200°C and strong oxidizing media, they can be used stably for 5-8 years. However, if the Plate Heat Exchanger Gaskets are frequently affected by mechanical vibrations, drastic pressure fluctuations, etc., the actual service life of various gaskets will be shortened to varying degrees.
