| Galvanized pipe, also known as galvanized steel pipe, is divided into hot-dip galvanizing and electroplating zinc. Hot-dip galvanized zinc layer is thick, with uniform coating, strong adhesion, and long service life. Electroplating zinc has low cost, the surface is not very smooth, and its corrosion resistance is much worse than hot-dip galvanized pipe. Classification: Galvanized steel pipes are divided into cold-galvanized steel pipes and hot-dip galvanized steel pipes. The former has been banned, and the latter is still encouraged by the country for temporary use. Hot-dip galvanized steel pipe tube base and the molten coating liquid have complex physical and chemical reactions, forming a tightly structured zinc-iron alloy layer with strong corrosion resistance. The alloy layer, pure zinc layer, and tube base are integrated. Therefore, its corrosion resistance is strong. Cold-galvanized steel pipe zinc layer is an electroplating layer, and the zinc layer and the tube base are independent and layered. The zinc layer is thin, and the zinc layer is simple. |

Categorization Galvanized steel pipes are divided into cold-galvanized steel pipes and hot-dipped galvanized steel pipes. The former has been banned, while the latter is still encouraged by the country for temporary use. The hot-dip galvanized steel pipe base body undergoes complex physical and chemical reactions with the molten galvanizing liquid, forming a tightly structured zinc-iron alloy layer with strong corrosion resistance. The alloy layer integrates with the pure zinc layer and the steel pipe base body, thus ensuring strong corrosion resistance. The zinc coating of the cold-galvanized steel pipe is an electroplating layer, and the zinc layer is independently layered from the steel pipe substrate. The zinc layer is quite thin, simply adhering to the steel pipe substrate, and is easy to peel off. Therefore, its corrosion resistance is poor. In new residential buildings, it is prohibited to use cold-galvanized steel pipes as water supply pipes. Usage Fire engineering: Currently, the fire water supply pipes are mostly made of galvanized pipes. On the surface of the galvanized pipes, a layer of paint is applied, which is the red fire hose that everyone can see. In fact, it is just a processed galvanized pipe. Steel Structure and Welding Engineering: Nowadays, many temporary workshops are being built outside, and in the past, these workshops were constructed using welded steel pipes. However, welded steel pipes are prone to rust, and to prevent rust, they need to be coated with a layer of paint. To address this issue, many new steel structure projects now directly use galvanized pipes, which can save labor hours and provide longer service life.
