Classification
|
1 |
Hot-dip galvanized pipe. The molten metal reacts with the iron matrix to create an alloy layer that allows the matrix and the coating to bond. Hot-dip galvanizing should first pickle the steel pipe to remove iron oxide on the surface of the steel pipe. After pickling, it should be cleaned with an aqueous solution of ammonium chloride or zinc chloride, and then sent to a hot-dip bath for hot-dip plating. The coating of hot-dip galvanizing is relatively uniform, the adsorption capacity is relatively strong, and the service life is long. |
|
2 |
Cold galvanized pipe. Cold galvanizing is electro-galvanizing. The amount of galvanizing is relatively small, and the corrosion resistance and service life are much worse than those of hot-dip galvanized pipes. |
|
3 |
Hot-dip galvanized steel pipe. The zinc-iron alloy layer formed by the reaction between the steel pipe and the plating solution, the alloy layer is integrated with the pure zinc layer and the steel pipe, and the corrosion resistance is relatively strong. |
|
4 |
Cold galvanized steel pipe. The zinc layer and the steel pipe are independent layers, the zinc layer is relatively thin, the zinc layer is simply attached to the surface of the steel pipe, and the zinc layer is easier to fall off, so it is not allowed to use cold galvanized steel pipe as a water pipe. |
