Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.
The dense zinc-iron alloy layer of the hot-dip galvanized steel pipe is integrated with the pure zinc layer and the steel tube base, which has strong corrosion resistance.
As long as the forming angle is changed, hot dip galvanized steel tubes of various calibers can be produced from strip steel of the same width.
Continuous bending and forming, the fixed length of the spiral tube is not limited, and the length can be customized.
The spiral welds are evenly distributed on the circumference of the spiral pipe, so the spiral pipe has high dimensional accuracy and strong strength.
It is suitable for the production of small batches and multiple varieties of spiral tubes. The welding seam of hot dip galvanized pipe is longer than the welding seam of straight seam pipe of the same specification. With the same wall thickness, the hot dip galvanized pipe bears the greatest pressure.

Hot dip galvanized pipe
The molten metal is reacted with an iron matrix to produce an alloy layer, thereby combining the substrate and the plating layer. Hot-dip galvanizing is to pickle the steel pipe first, in order to remove the iron oxide on the surface of the steel pipe, after pickling, it is washed by ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride, and then fed. Hot dip plating tank. Hot-dip galvanizing has the advantages of uniform plating, strong adhesion and long service life. Most of the northern processes use galvanized strips to directly coil the zinc.
