This standard specifies the basic requirements for the construction mass assessment of anti-corrosion engineering of wet desulfurization chimneys (flue), covering anti-corrosion engineering such as base treatment, coatings, fiber reinforced plastics, foam bricks, metal materials, acid-resistant castables and corrosion-resistant rubber. This standard is applicable to the construction mass acceptance and evaluation of anti-corrosion engineering of chimneys and flue after wet desulfurization. Through the implementation of this standard, the mass of anti-corrosion engineering of desulfurization chimneys can be ensured to meet the design requirements, and the service life and safety of chimneys can be improved.
