Analysis of Corrosion Causes of Circular Cooling Tower

Circular cooling equipment materials are usually carbon steel, stainless steel and copper. When carbon steel tube sheets are used as cooling towers, the welds between the tube sheets and the tubes often show corrosion and leakage. Cause environmental pollution and material waste. In the manufacture of cooling towers, the welding of tube sheets and tubes is generally performed by manual arc welding, and the shape of the weld has different degrees of deficiencies, such as depressions, pores, slag inclusions, etc., as well as welding stress. uneven distribution. When in use, the tube sheet is partially in contact with industrial cooling water, and impurities, salts, gases and microorganisms in the industrial cooling water will corrode the tube sheet and welds. Studies have shown that industrial water, whether fresh or sea water, has various ions and dissolved oxygen, where the concentration of ions and oxygen changes, which plays an important role in the corrosion shape of the metal. In addition, the complexity of the metal structure also affects the corrosion pattern.
