Heat exchanger cleaning problem
Thread Content
Our company needs to purge the heat exchanger during every maintenance. Since we use superheated steam, we found that some anti-corrosion layers fell off after the shutdown. We plan to clean the lines after adding temperature and pressure reduction to each set of equipment. Please discuss whether it is feasible.
That is necessary. I wonder how many kilograms of superheated steam you are talking about and what is its temperature?
The steam we use is 1.0MPa, 200℃.
The anti-corrosion layer refers to applying a layer of paint to the cooler, condenser, and heat exchanger tube bundles so that the heat exchanger tube bundles can achieve the effects of scale inhibition, water resistance, high temperature resistance, and corrosion resistance after being anti-corrosion, and extend the service life of the equipment. Anti-corrosion is divided into external anti-corrosion and internal anti-corrosion.
