Submerged arc steel pipes high-frequency welding process
1. The control of the weld gap: the strip steel is sent to the welded pipe unit after rolling by multiple rollers. The strip steel is gradually rolled up to form a circular tube blank with an opening gap. Adjust the reduction of the extrusion roller to control the gap between ...Read more -
Tips to identify fake and inferior steel pipes
Shoddy steel pipes are prone to folding. Folding is a variety of fold lines formed on the surface of the steel pipe, and this defect often runs through the longitudinal direction of the entire product. The reason for the folds is that the counterfeit and inferior manufacturers...Read more -
Treatment measures for common problems in pre-welding of straight seam steel pipes
1. Wrong side. This is a common problem in pre-welding, and the wrong side is out of tolerance, which directly leads to the degradation or scrapping of the straight seam steel pipe. Therefore, it is required to strictly control the misalignment amount during pre-welding. When ...Read more -
