Galvanized seamless pipes sound high-end.
Galvanized seamless pipes are generally hot-dip galvanized with a thick galvanized layer, making them more corrosion-resistant and have a longer service life.
With the improvement of building quality, the requirements for the service life and strength of pipeline systems have also increased. The product often replaces galvanized steel pipes and is used for pipeline systems with higher requirements for fire protection, air conditioning, and other circulating water and gas medium transportation.
Galvanized steel pipes have a more plain appearance compared to galvanized seamless steel pipes.
The "galvanized" coating is uniform and has strong adhesion, but this is not a simple process similar to applying skincare products on the face. Hot dip galvanizing is the process of first pickling welded steel pipes. In order to remove the iron oxide on the surface of the steel pipe, after pickling, it is cleaned in an ammonium chloride or zinc chloride aqueous solution or a mixed ammonium chloride and zinc chloride aqueous solution tank, and then sent to a hot-dip galvanizing tank.
The hot-dip galvanized steel pipe substrate undergoes complex physical and chemical reactions with the molten plating solution, forming a corrosion-resistant and tightly structured zinc iron alloy layer. The alloy layer is integrated with the pure zinc layer and the steel pipe substrate.
