Galvanizing process and advantages of flange

　　The process of hot-dip galvanizing of flange is Pickling - assisted plating - drying - hot-dip galvanizing - Separation - cooling passivation. Customers who buy flanges will determine whether they are galvanized according to the use requirements of flanges. Hot dip galvanizing is an effective way of metal corrosion prevention, which is mainly used in metal structures and facilities in various industries.

　　Advantages of hot dip galvanized flange:

　　1. The cost of hot-dip galvanizing for rust prevention is lower than that of other paint coatings;

　　2. Durability: in the suburban environment, the standard thickness of hot-dip galvanized rust prevention can be maintained for more than 50 years without repair; In urban or offshore areas, the standard hot-dip galvanized antirust coating can be maintained for 20 years without repair; III. good reliability: the zinc coating and steel are metallurgically combined and become a part of the steel surface, so the durability of the coating is more reliable;

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

　　4. comprehensive protection: every part of the plated parts can be plated with zinc, and can be fully protected even in depressions, sharp corners and hidden places;

　　5. time saving and labor saving: the galvanizing process is faster than other coating methods, and the time required to brush on the site after installation can be avoided.

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