China supplier 4 inch galvanized steel seamless round pipe Cold Drawn Seamless Weld Precision steel pipe tube price per meter

Products Description

The molten metal reacts with the iron matrix and produces an alloy layer, so as to combine the matrix and the coating. Hot dip galvanizing is the first steel pipe pickling, in order to remove iron oxide on the surface of the steel pipe, pickling, through ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank for cleaning, and then into the hot dip plating tank. Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.

1. Low processing cost: the cost of hot-dip galvanized rust prevention is lower than that of other paint coatings.

2, good reliability: the durability of the coating is more reliable.
3, durable: hot dip galvanized steel pipe with surface gloss, uniform zinc layer, no leakage plating, no dripping, adhesion strong break net corps, strong corrosion resistance characteristics, in the suburban environment rose significantly, the standard hot dip galvanized rust thickness can be maintained for more than 50 years without repair; In urban and offshore areas, standard hot-dip galvanized rust protection can be maintained for 20 years without repair.

4, the toughness of the coating is strong: the galvanized layer forms a special metallurgical structure, which can withstand
mechanical damage during transportation and use.
5, comprehensive protection: every part of the plated parts can be plated with zinc, even in the depression, sharp corners and hidden places can be fully protected.
6, save time and effort: galvanizing process is faster than other coating construction method
