Causes and treatment methods of plate heat exchanger string liquid

1. Due to improper selection of plate heat exchanger plates, cracks or perforations are caused by plate corrosion.

2. The operating conditions do not meet the design requirements.

3. The residual stress after cold stamping of the plate and the clamping size during assembly are too small to cause stress corrosion.

4. There is a slight leakage at the plate leakage groove, which causes the harmful substances in the medium (such as C1) to concentrate and corrode the plates, forming a stream of liquid.

1. Replace the cracked or pierced plate, and use the light transmission method to find the crack on the plate.

2. Adjust the operating parameters to meet the design conditions.

3. The clamping size of the plate heat exchanger during maintenance and assembly should meet the requirements, not as small as possible.
