Galvanized steel pipes are divided into hot-dip galvanizing and cold-galvanizing. The hot-dip galvanizing is to soak the pipe in the high-temperature zinc liquid so that the zinc penetrates into the surface of the steel. The surface of the pipe has a thick zinc layer and corrosion resistance higher than that of cold-dip galvanizing. Of course, the price is also higher than that of cold-dip zinc. Cold-dip zinc is actually an electro-galvanized pipe. A layer of zinc adheres to the surface of the tube by electroplating chemical reaction, but the zinc layer is thin and easily falls off. The price is cheaper. The price of both is higher than that of ordinary steel pipes. After special spraying on the surface of galvanized pipes, the anti-corrosion performance is dozens of times higher than that of iron pipes.
The specific difference between galvanized steel pipe and ordinary steel pipe:
1. Differences in manufacturing process: Galvanized steel pipes and ordinary steel pipes are two categories of steel pipes. Zinc plating means that the surface of steel pipes is galvanized, and ordinary steel pipes are not.steel coils suppliers
2. the difference in durability: galvanized pipe is more resistant to corrosion, ordinary steel can withstand higher pressure. Galvanized steel pipes are not easy to rust due to the protection of zinc, and galvanized steel pipes are lighter than ordinary steel pipes.
3. the difference of use: galvanized steel pipe is generally used to do fences, fences, guardrails and so on. Widely used in municipal engineering, roads, factories, schools, development zones, gardens, plazas, residential areas and other places. Ordinary steel pipes are now basically replaced by galvanized steel pipes.
