Product Description

Hot-dip galvanized pipe is to pickle the steel pipe first to remove iron oxide on the surface of the steel pipe. Then, it is cleaned in the mixed aqueous solution tank of ammonium chloride and zinc chloride, and then sent to the hot dip plating tank. The steel tube substrate undergoes complex physical and chemical reactions with the molten plating solution to form a corrosion-resistant zinc-iron alloy layer with a compact structure. The alloy layer is integrated with the pure zinc layer and the steel tube substrate. Therefore, it has strong corrosion resistance.
Galvanized has stronger protective effect and strong corrosion resistance. The whole structure is made of zinc, forming a dense quaternary crystal, which forms a barrier on the steel plate, thus effectively preventing the penetration of corrosion factors.

Production workshop
Hot-dip galvanized square tube: It is a square tube made of steel plate or steel strip after crimping and welding. A square tube formed.

Galvanized pipe advantages:

1. Low processing cost of hot-dip galvanized square pipe: The cost of anti-rust of hot-dip galvanized is lower than that of other paint coatings. 2. The galvanized square pipe is durable: in the suburban environment, the standard hot-dip galvanized anti-rust thickness can be maintained for more than 50 years without repairing; in urban or offshore areas, the standard galvanized anti-rust layer can be maintained for 20 years years without having to repair.
3. Good reliability of the galvanized square tube: the combination between the galvanized layer and the steel is a metallurgical combination, so that the zinc becomes a part of the steel surface, so the durability of the coating is better.
4. The toughness of the coating of the galvanized square tube is strong: the galvanized layer forms a special metallurgical structure, which can withstand mechanical damage during transportation and use.

Product Quality Test

1.) Visual inspection Visually inspect all galvanized parts, and their main surfaces should be smooth, free of drips, roughness and zinc thorns, no peeling, no missing plating, and no residual solvent slag, in parts that may affect the use or corrosion resistance of galvanized workpieces There should be no zinc nodules and zinc dust.
2.) Thickness inspection When the size of the article allows, the thickness measurement of the coating shall not be carried out in the area less than 10mm from the edge, the flame cut surface or the corner. The coating thickness is defined by the minimum value of each local coating thickness measured.
3.) Thickness measurement position The local thickness of the coating shall be measured at the point where the coating thickness is at its thinnest possible.
4.) Leak plating and repair Leakage plating The total area of the leakage surface of galvanized parts should not exceed 0.5% of the total production area. The area of each leakage plating surface should not exceed 10cm2.

Product Application

Galvanized steel pipe application:
Galvanized square pipe is mainly used for curtain wall, construction, machinery manufacturing, steel construction projects,
shipbuilding, solar power brackets, steel structure engineering, power engineering, power plants, agricultural and chemical
machinery, glass curtain walls, automobile chassis, airports, etc.
