The storage of plate heat exchanger is special because it contains rubber gasket. Generally, it should be carried out in accordance with the requirements of rubber, such as avoiding light, ventilation, ozone, etc., with certain temperature and humidity requirements. When it is not used for a long time, the gasket should be kept loose to avoid permanent deformation and keep elastic state. The following are some requirements of some foreign companies for plate replacement storage for reference.

When the equipment needs to be stored for a long time (more than one month) before use, appropriate protective measures should be taken to prevent unnecessary loss of the equipment
1: It is better to store the equipment indoors, the indoor temperature is 15 ℃
~ 20
℃
(60 f ~ 70 f), and the humidity is about 70%;
2: There should be no ozone generating equipment in the room, such as electrode, welding equipment, etc. ozone can destroy many rubbers (crack);
3: Organic volume and acid solution should not be stored indoors, and thermal radiation and ultraviolet radiation should be avoided;
4: It is better to put the equipment in the packing box before installation;
5: The metal plate should be covered with opaque plastic film;
6: The surface of bolt should be coated with better antirust liquid;
7: The heat exchanger should be emptied, and it is recommended to clean and dry the equipment before storage according to the different media.
8: Seal flange or nozzle openings and all other openings;
9: Anti rust and anti-corrosion measures shall be taken on the surface of carbon steel;
