How to choose an anti-corrosion coating for the heat pipes in flue gas heat exchangers? In the low-temperature flue gas systems of heating furnaces in power plants, steel mills, oil, and petrochemical industries, the fins and heat pipes of the heat exchangers suffer severe corrosion; those made of ND steel often become unusable after just one year of use, while stainless steels resistant to flue gas are expensive. What type of anti-corrosion material can be used to prevent corrosion in heat pipes?
Isn’t it time to invent plastic? ? ?
