Cooling towers will be affected by corrosion. The primary reason is that the welding skills of the tube plate and tube are generally able to adopt the traditional craft arc welding. There are some disadvantages to the shape of the weld and different levels of education. During use, the tubesheet components come into contact with industrial cooling water. Analyzing industrial wastewater for impurities or other components can lead to corrosion of tube plates and welds. The closed cooling tower puts the tubular heat exchanger into the tower, and ensures the cooling effect through the heat exchange of circulating air, spray water and circulating water. If you do not need to use Beijing cooling tower in winter, it is necessary to discharge spray water and internal circulating water when closing. The principle of the open cooling tower is to spray the circulating water on the filler of the glass fiber, and to complete the heat exchange through the contact of water and air.

The traditional teaching method is repair welding, but repair welding is easy to cause internal stress in the internal management of tube plate, difficult to eliminate. Otherwise, the welding of cooling tower tube plate may leak again. Therefore, in order to effectively control the corrosion protection of cooling tower, the group company initiated the internal and external corrosion prevention treatment of pipeline enterprises from the root of raw materials. Well done.

We can know that, according to the material selection of the shell, the closed cooling tower can be divided into galvanized steel plate closed cooling tower, galvanized steel plate closed cooling tower, stainless steel closed cooling tower, glass steel closed cooling tower, etc.

Galvanized steel plate: can be useful to avoid steel corrosion, extend the service life. Galvanized steel plate (thickness is 0.4 ~ 1.2mm) is also known as galvanized iron sheet, commonly known as sheet iron. Galvanized steel plate is widely used in construction, vehicles, household appliances, daily necessities and other occupations.

Aluminum zinc alloy steel plate: has outstanding heat resistance, can accept the high temperature above 300 degrees Celsius. The corrosion resistance of galvanized sheet is mainly attributed to aluminum. After wearing down the zinc, the aluminum will form a fine layer of alumina to avoid further internal corrosion.

Stainless steel: Abbreviation for corrosion resistance of stainless steel, air, steam, water, and other weakly corrosive media or stainless steel; The corrosion and chemical resistance of the medium (acid, alkali, salt and other chemical corrosion) is called acid resistant steel.
