Combined with previous passivation treatment scenarios for industrial static equipment such as stainless steel towers and heat exchangers, incomplete passivation films will directly lead to operational risks for many types of equipment. The core consequences are as follows: The corrosion rate is greatly accelerated. The incomplete passivation film cannot isolate the corrosive medium. The exposed metal matrix is in direct contact with the medium to form a micro-corrosion battery. The local corrosion rate will be significantly increased. This is the most direct core consequence. Various types of localized corrosion are most likely to occur in working environments containing chloride ions, acid and alkali, and defective locations can easily induce pitting corrosion and crevice corrosion. Intergranular corrosion may also occur in the welding heat-affected zone, which further causes stress corrosion cracking under the action of tensile stress, directly damaging the structural integrity of the equipment. Dramatically shorten the service life of equipment. Originally, a complete passivation film can maintain a protection period of several years. Defects in the film layer will cause rust to appear on the equipment within a few months. The frequency of unplanned downtime and maintenance will increase significantly, and the overall service life of the equipment will be directly shortened by 30% to 50%. It may also cause safety hazards such as media leakage. Contaminated process media In scenarios with high cleanliness requirements such as food, medicine, and fine chemicals, metal ions generated by corrosion will be mixed into materials, directly affecting product purity and failing to meet industry compliance requirements.
