Ji'nan galvanized pipe in the process of our decoration is more commonly used, also called galvanized steel pipe, hot galvanizing and galvanizing two kinds. Hot galvanized zinc coating is thick, with uniform coating, strong adhesion, long service life and so on. Galvanized pipe is very widely used. Today, the small editor of the Ji'nan galvanized pipe manufacturer will introduce the classification and specifications of the galvanized pipe for you.
First, the classification of galvanized pipes
1. Hot-dip galvanized pipe. It is to make the molten metal react with the iron matrix to produce the alloy layer, so that the matrix and the two layers of the coating are combined. Hot dip galvanizing is to pickle steel pipes first, then remove iron oxides on the surface of steel pipes, then pickle them, then clean them through ammonium chloride or zinc chloride water solution or ammonium chloride and zinc chloride mixed water solution tank, then send them into hot dip bath.
2. Cold galvanized pipe. Cold galvanizing is electrogalvanizing with little amount of zinc, only 10-50g/m2, and its corrosion resistance is much different from that of hot galvanized pipe. Regular galvanized pipe manufacturers, in order to ensure quality, most of the use of galvanizing (Leng Du). Only small businesses of small size and old equipment use galvanizing, of course their prices are relatively cheap.
3. Hot-dip galvanized steel pipe. The complex physical and chemical reactions occurred between the steel tube matrix and the molten plating bath to form a corrosion-resistant and tightly structured zinc - iron alloy layer. The alloy layer is integrated with the pure zinc layer and the steel tube matrix. Therefore, its corrosion resistance is strong.
4. Cold galvanized steel pipe. The zinc layer is electroplating layer, and the zinc layer and the steel tube matrix are stratified independently. The zinc layer is thinner and the zinc layer is simply attached to the steel tube matrix, which is easy to fall off. Therefore, its corrosion resistance is poor. In newly built houses, cold galvanized steel pipes are forbidden to be used as water pipes.
Ji'nan galvanized pipe specification:
In order to improve the corrosion resistance of the steel tube, the galvanized steel tube is galvanized. The galvanized steel tube is divided into two kinds of hot dip galvanizing and galvanizing, the hot galvanized zinc coating is thick, the electrogalvanizing cost is low, and the surface is not very smooth.
