[The galvanized pipes sold by our factory all comply with national standards]
Galvanized steel pipes are galvanized The main functions of zinc are the following two points: Zinc is more chemically active than iron. When electrochemical corrosion occurs, zinc corrodes first instead of iron. The oxide of zinc is relatively dense, which can prevent further oxidation. Therefore, usually galvanized steel pipes have better corrosion resistance. The high corrosion resistance of galvanized steel is mainly related to the galvanic effect. When part of the zinc layer is damaged and the steel matrix is exposed, a bimetallic pair is formed on the same plane. Based on the corresponding theoretical model, the two parameters of protection distance and galvanic current can be used to quantitatively describe the degree of galvanic protection and the consumption rate of zinc coating.
