Electro-galvanized for Seamless Steel Pipe
Galvanizing can not only beauty the surface of the seamless steel pipe , but also protect pipe from rusting. The types of galvanizied for seamless steel pipes are hot-dip galvanized and electro-galvanized. Here we will introduce you electro-galvanized. Currently, electro-galvanizied can be classified into four types according to the classification of electroplating solution. 1. Cyanide Galvanized. But cyanide is highly toxic, it has severe damage to the environment. With the promotion of environmental protection concepts, there are many restrictions on the use of cyanide in electroplating zinc. Currently, people mainly use microcyanide electroplating solution instead. After electroplating with cyanide galvanized, the product especially for color plating, and the color remains good after passivation. 2. Zincate Galvanized, it is evolved from cyanide zinc plating. This process has strong corrosion resistance and is good for color galvanizing. With this process, the latt...
