Product Description

Our pipes undergo a Chromic Acid  passivation treatment for the surface of galvanized steel pipe. As a rule, hydrogen treatment and passivation treatment are the two major methods for the final effective painting treatment of galvanized pipe, in order to further improve the corrosion resistance of the zinc layer or maintain the original property of the coating. Furthermore, it also helps to prolong the durable years of the pipes. Generally speaking, our pipes can be used for at least 3 ~ 5 years, sometimes even up to 20 years. In that regard, there alsohas much to do with the specific environment in the actual applications.
