How to prevent corrosion in the tube side and shell side of a heat exchanger? Can heat exchange tubes be coated with anti-corrosion materials on both the inside and outside? Please, experts, help! Thank you so much!
Painting, timely rust removal, upgraded materials
Should welding be done first and then anti-corrosion treatment, or should anti-corrosion treatment be done first and then welding?
The heat exchange tubes can be coated internally for corrosion protection.
Anti-corrosion work should be carried out after the pressure testing is complete, as equipment that has undergone anti-corrosion treatment must not be welded again to prevent damage to the coating. The inner and outer walls of the heat exchange tube can both be treated for corrosion protection. The specific construction standards shall refer to the 70B110-2005 Technical Requirements for the Application of Anti-corrosion Coatings on Shell-and-Tube Heat Exchangers.
The heat exchange tubes can be made of corrosion-resistant materials, and the shell is also corrosion-resistant
For anti-corrosion treatment of heat exchangers, it mainly involves protecting the tube bundle; anti-corrosion measures can be applied both inside and outside the tubes. Different anti-corrosion materials should be selected based on the temperature of the medium; for specific questions, please contact me privately
