Analysis of the Mechanism of Black Spot Formation on the Sur-face of Hot-dip Galvanized Steel Pipes
During the manufacturing process of hot-dip galvanized steel pipes,black spot defects may sometimes appear on their surface,which has been a long-standing problem for both manufacturers and users.Black spots not only affect the appear-ance quality of products,but also have adverse effects on their corrosion resistance and processing performance.In order to solve this problem,this article analyzes the formation mechanism of black spots on the surface of hot-dip galvanized steel pipes and determines the main reasons for the formation of black spots.On this basis,this article proposes corresponding pre-vention and control measures,aiming to provide reference for the quality control of hot-dip galvanized pipes.
