Galvanized hollow steel pipe is a square or rectangular-section steel pipe that has undergone hot-dip galvanizing treatment. It has a hollow structure inside. While maintaining sufficient strength, it improves the efficiency of transportation and installation. The hot-dip galvanizing process involves immersing the steel pipe into molten zinc liquid, forming a uniform and dense zinc layer on its surface, thus enhancing the corrosion resistance of the steel pipe.

Hot-dip seamless steel pipe manufacturing process. The manufacturing process of hot-dip seamless steel pipes includes acid pickling, washing with ammonium chloride or zinc chloride solutions, and finally hot-dip galvanizing. Here is a more detailed description of the process:1. Acid Pickling (Remova

Hot-dip galvanized seamless steel pipes are widely used in various industries, including construction, oil, and chemicals, due to their excellent corrosion resistance and strength. This article will provide a brief overview of their production process and practical applications to help readers bette

What is the difference between galvanized steel pipe and seamless steel pipe?Hot-Galvanized steel pipe and seamless steel pipe are two types of steel pipes. There are many differences between the two, as follows: The manufacturing process difference between galvanized steel pipe and seamless steel p

Hot dipped galv.seamless steel pipe is a steel pipe coated with a layer of zinc on the surface. The molten metal reacts with the substrate to form an alloy layer, so that the coating and the substrate are firmly bonded, and the thickness of the coating is uniform. It also has good corrosion resistance due to its galvanized coating.

The hot-dipped galvanizing refers to the metal surface treatment. The metal product will be immersed it in the bath of the molten zinc. The whole process of the hot-dipped galvanizing process can be divided into 3 parts, like the surface preparation, galvanizing, and inspection.
