Anticorrosion coating issues for heat exchange tubes in the petrochemical industry
Thread Content
The heat exchange tubes of the water cooler require anti-corrosion coating; please have the coating manufacturers or construction teams provide their opinions
Use pressure, medium, flow rate, temperature? You can add QQ 2508736771 for further discussion
With years of experience, the anti-corrosion measures for water coolers are nothing but a form of deception.

Based on practical experience, anti-corrosion treatment is not recommended; the poor quality of the coating makes it not worth the effort, and it’s better to replace the core when its lifespan is up
It is very necessary to ensure good corrosion protection; the main concern is defects in the quality of construction

Our company handles many projects related to corrosion protection for heat exchangers; we have already completed numerous large-scale installations for Tianjin Zhongsha Petrochemical, with excellent results in terms of corrosion prevention.

Generally, heat exchangers are protected against corrosion; corrosion protection is usually applied only to the end caps and the end plates of the tube bundle. Applying such protection inside or outside the tube bundle will essentially reduce the heat transfer efficiency... It’s better to replace the tube bundle regularly or use higher-grade materials for it
Corrosion and scale prevention are very necessary and important. I have seen physical scale removal devices installed at the water supply side, and the pictures show that they are effective to some extent.
