What are the advantages and disadvantages of galvanized steel pipe?
Hot-dip galvanized steel pipes are widely used in construction, machinery, coal mines, chemicals, electric power, railway vehicles, automobile industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery and other manufacturing industries. Next, the editor will introduce the advantages and disadvantages of galvanized steel pipes, let's take a look.
Advantages: The hot-dip galvanizing layer is thick bai, which has the advantages of uniform coating, strong adhesion, and long service life. The cost of electro-galvanizing is low, the surface is not very smooth, and its corrosion resistance is much worse than that of hot-dip galvanized pipes.
Disadvantages: The zinc layer of cold galvanized steel pipe is an electroplated layer, and the zinc layer is separated from the steel pipe matrix. The zinc layer is thin, and the zinc layer simply adheres to the steel pipe substrate and is easy to fall off. Therefore, its corrosion resistance is poor. In newly-built houses, it is forbidden to use cold galvanized steel pipes as water supply pipes.
Galvanized pipe use
1. Fire-fighting engineering: The current fire-fighting water supply pipes are basically galvanized pipes, and a layer of paint is applied to the outer layer of the galvanized pipes, so that everyone can see the red fire-fighting pipes, which are actually only plated. Zinc tube is formed by processing.
2. Steel structure and welding engineering: Now many scaffolding workshops outside, the old workshops were built with welded steel pipes, but the welded steel pipes are prone to rust. In order to prevent rust, a layer of paint must be applied. In order to solve this problem, Nowadays, many new steel structure projects directly use galvanized pipes, which can save man-hours and can last longer.
3. Agriculture: mainly used to build warm greenhouses, flower sheds, and pillars for flowers and melons.
