2.The manufacturing process of ERW steel pipe
To create ERW pipe, a flat steel strip is first shaped into a rounded tube through cold forming. This tube is then passed through a series of forming rollers, which create a longitudinal seam. Rather than using filler metal, the two edges of the seam are heated with a high frequency current and compressed to form a bond.
Throughout the welding process, any contaminants in the heat-affected zone are forced out of the seam. This results in a clean, strong bond that doesn't require additional material to hold it together. Overall, the ERW process is efficient and effective, producing high-quality pipe that is used in a wide range of applications.
