Process characteristics of galvanized pipe
Author：
The biggest advantage of sulfate galvanizing is that the current utilization rate reaches 100%, and the deposition rate is very fast. However, because the crystallization of the coating is not detailed enough, the deep plating ability is poor, and it is only suitable for pipes and wires with simple geometric shapes. After the improvement of the process, iron salt is also added to the original solution, which not only inherits the advantages of traditional sulfate zinc plating, but also strengthens the ability of deep plating. After continuous improvement, the coating grains for wires and pipes are more delicate and shiny than before.
