What are the replacement and precautions for plate heat exchanger gaskets?
Improper use of plate heat exchanger gaskets or long service life is easy to damage or aging. Once a problem occurs, it will affect the normal operation of heat exchange equipment. Therefore, when we find that the gasket is damaged, it should be replaced immediately. However, the replacement should pay attention to specific methods, in order to give full play to its practical application effect. Below, we will give you a detailed introduction to the replacement of plate heat exchanger gaskets and what to pay attention to.
The proper way to replace the plate heat exchanger gasket is as follows:
1. Take out the aged gasket and observe it carefully. Choose a cleaning method based on the stains above. Washed gaskets of plate heat exchangers are not easily corroded by chemicals.
2. After cleaning the plate heat exchanger, use high-pressure purging equipment to completely eliminate the residual organic chemicals on the plate heat exchanger.
3. If signs of corrosion of the plate heat exchanger are found, the inner wall of the plate heat exchanger and the pipes of the heat exchanger should be inspected and derusted.
4. For the bonding gasket, be sure to remove the stains on the plate heat exchanger before bonding, otherwise it will endanger the sealing characteristics of the plate heat exchanger.
5. Another point for the replacement of plate heat exchanger gaskets and precautions is that after the plate heat exchanger gasket is replaced, the airtightness of the plate heat exchanger should be tested for airtightness to check whether there is any abnormality in the whole process of testing. , and record the relevant data information of the test.
