What coating system is suitable for the anti-corrosion coating of heat pipes in low-temperature wet flue gas heat exchangers?
Thread Content
In the flue gas systems of heating furnaces in power plants, steel mills, oil, and petrochemical industries, the fins and heat tubes of the heat exchangers suffer severe corrosion; heat tubes made of ND steel become unusable after just one year of use, while stainless steel resistant to flue gas is expensive. What type of anti-corrosion material can be used to prevent corrosion in heat pipes?
At present, stainless steel is still the most commonly used material. As for coatings, there are yet no well-documented examples showing their effectiveness; let’s see if Haichuan has any better solutions
Is the temperature high? What is the medium? Good heat exchange performance is required; the model can be selected based on this
A high-temperature resistant anti-corrosion alloy can be bonded to ordinary substrates; the manufacturing process requires high precision, with no pores or micro-cracks allowed. . . :)
