Galvanizing process and advantages of flange
The process of hot dip galvanizing of flange is pickling, assistant plating, drying, hot dip galvanizing, separation, cooling and passivation.
Customers who buy flange will decide whether to galvanize according to the application requirements of flange. Hot dip galvanizing is an effective metal anti-corrosion method, which is mainly used in metal structure facilities of various industries. It is to immerse the steel parts after rust removal into the molten zinc melted at about 500 ℃ to make the surface of the steel members adhere zinc layer, and then play the purpose of anti-corrosion.
The anticorrosion life of hot galvanizing is long, but the anticorrosion life is different in different environment.
Advantages of hot dip galvanized flange:
Low cost: the cost of hot dip galvanizing is lower than that of other coatings;
Durable use: in suburban environment, the standard thickness of hot-dip galvanized anti rust coating can be maintained for more than 50 years without repair; in urban or offshore areas, the standard thickness of hot-dip galvanized anti rust coating can be maintained for 20 years without repair.
Good fastness: the zinc coating is metallurgically bonded with the steel and becomes a part of the steel surface, so the durability of the coating is relatively reliable;
Strong toughness of the coating: the zinc coating forms a special metallurgical structure, which can accept mechanical damage during transportation and use;
Comprehensive maintenance: every part of the plating parts can be coated with zinc, even in the depression, sharp corner and hidden place can be fully maintained;
Time saving and labor saving: the galvanizing process is faster than other coating construction methods, and can prevent the time required for painting on site after installation.
