The importance of flange galvanizing

Galvanized flange is usually carbon steel flange, carbon steel flange cost is lower, but far less than stainless steel, alloy steel and other materials of corrosion resistance; in order to achieve corrosion resistance and prolong its service life, but also can save cost, usually using galvanized method.

The advantages of flange galvanizing are:

(1) Every part of the coating can be galvanized by flange galvanizing, which forms a special metallurgical structure. Even if it is mechanically damaged in the process of transportation and use, the structure will not have much impact. Even in the groove, the sharp corner and hidden position can be completely protected, so the durability of the coating is more reliable. Generally, in the suburban environment, the standard hot-dip coating is recommended Zinc antirust thickness can be maintained for more than 50 years without maintenance; in urban or offshore areas, the standard hot-dip galvanized coating can be maintained for 20 years without maintenance.

(2) The galvanizing process is faster than the construction of other coatings, and can avoid the time required for on-site painting after installation. The cost of hot-dip galvanizing is relatively low.
