1. Types of plate heat exchanger gaskets There are mainly the following types of plate heat exchanger gaskets:
Rubber gasket: Rubber gasket has good elasticity and sealing performance, and is suitable for low pressure and low temperature occasions.
Asbestos rubber gaskets: Asbestos rubber gaskets are made of asbestos and rubber and are suitable for medium pressure and low temperature applications.
Polyethylene gasket: Polyethylene gasket has good corrosion resistance and sealing performance, and is suitable for medium pressure and high temperature applications.
Metal-coated gaskets: Metal-coated gaskets are made of metal sheets, asbestos rubber and other materials, and are suitable for high-pressure and high-temperature applications.
2. Selection of plate heat exchanger gaskets
When selecting plate heat exchanger gaskets, you need to consider the following factors:
Operating temperature: The temperature that the gasket can withstand should match the operating temperature of the heat exchanger.
Working pressure: The gasket should have sufficient strength and sealing performance to withstand the working pressure of the heat exchanger.
Material: The material of the gasket should be compatible with the fluid inside the heat exchanger to avoid corrosion and leakage.
Cost: On the premise of meeting performance requirements, lower cost gaskets should be selected.
3. Use of plate heat exchanger gaskets
When using plate heat exchanger gaskets, you need to pay attention to the following points:
When installing the gasket, ensure that its contact with the heat exchanger plate is flat to avoid gaps and leaks.
Regularly check the use of gaskets and replace them in time if damage or aging is found.
When disassembling the heat exchanger, avoid damaging the gasket to avoid affecting its reuse.
In short, the selection and use of plate heat exchanger gaskets are of great significance to ensure the normal operation of the heat exchanger and extend its service life. In actual applications, it is necessary to select appropriate gaskets according to specific working conditions and requirements, and use and maintain them rationally.
