  Advantages of hot dip galvanized flange:

  1. Low cost: the cost of hot dip galvanizing is lower than that of other coatings;

  2. Durable: in suburban environment, the standard thickness of hot-dip galvanizing antirust coating can be maintained for more than 50 years without repair; in urban or offshore areas, the standard thickness of hot-dip galvanizing antirust coating can be maintained for 20 years without repair; 3. Good reliability: the galvanized coating and steel are metallurgically bonded to form a part of the steel surface, so the durability of the coating is relatively reliable;

  4. Strong toughness of the coating: the zinc coating forms a special metallurgical structure, which can withstand mechanical damage during transportation and use;

  5. Comprehensive protection: every part of the plating parts can be coated with zinc, even in the depression, sharp corner and hidden place can be fully protected;

  6. Time saving and labor saving: the galvanizing process is faster than other coating construction methods, and can avoid the time required for painting on site after installation.

  Galvanized flange is to strengthen the corrosion resistance of carbon steel flange, a layer of zinc is plated on the surface of flange, so as to achieve the purpose of corrosion resistance.

  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 at about 500 ℃ to make the surface of steel members adhere zinc layer, so as to achieve the purpose of anti-corrosion. The anticorrosion period of hot galvanizing is very long, but the anticorrosion period is different in different environments: 13 years in heavy industry zone, 50 years in ocean, 10 years in suburb.
