As we all know, plate heat exchangers use plates to conduct heat. After a long period of use, plate heat exchangers must be maintained and cleaned. In order to ensure that the plate heat exchanger can be used normally in the later stage. Preservative work is essential. The following describes the anti-corrosion skills of plate heat exchangers:
The plate heat exchanger has high thermal efficiency and a relatively compact structure, which saves time for users when cleaning and disassembling. Simply change the heat area of the plate heat exchanger. It is now used by most manufacturers such as biological fermentation and heating used widely. In view of this, we will communicate and discuss the selection, evaluation, installation, protection and maintenance of plate heat exchangers.
We need to consider the ability of plate heat exchanger materials to engage in media corrosion. Anticorrosion work must be started from the source and carefully selected from the raw materials of plate heat exchangers. The stainless steel plate is subjected to external passivation treatment to form a solid and very thin film on the surface of the oxide film, and then achieve excellent corrosion resistance.
When planning the forming die of the plate heat exchanger plate, a structure with a small residual stress should be selected. In order to reduce scratches on the outer surface of the plate heat exchanger plate, it is necessary to polish the outer surface of the mold.
Adhesives for sheets and gaskets. Do not use expired and chloride-rich adhesives. Add the touch rate of the plate heat exchanger plate contacts to reduce damage to the contacts.
Doing a good job of anti-corrosion of plate heat exchangers is our guarantee when we use plate heat exchanger equipment. Therefore, when you use plate heat exchangers, you must do maintenance work regularly. Anticorrosion can actually be prevented.
