Galvanized pipes are divided into hot galvanized pipes and cold galvanized pipes according to different galvanizing methods. What are the characteristics of hot galvanized pipes and cold galvanized pipes? Next we will analyze it according to Jinan galvanized pipe.
1. Because of the different galvanizing methods of the two galvanized pipes, the amount of galvanizing is different. The amount of galvanizing on cold galvanizing is less and the corrosion resistance is poor. Hot galvanizing is much better than hot galvanizing.
2. The surface gloss of hot-dip galvanizing is not as good as that of cold-dip galvanizing.
3. Hot-dip galvanized steel pipe has the advantages of good plasticity, high strength and good wear resistance. In addition, the two kinds of galvanized pipes can basically withstand low temperature, especially suitable for the northern freezing environment.
