| Abstract: | In order to improve the product quality and production efficiency of HFW welded pipe, during HFW welded pipe production the common problems of steel belt edge bulge, steel pipe surface scratch, weld misalignment and steel belt running-off were analyzed, found the reasons and given preventive measures. The practical production effect indicated that the raw material dimension control, rational roll pass and technological parameter design, accurate roll position installation, rational using of lubricants and some other measures could solve the problems of steel belt edge bulge, steel pipe surface scratch and steel belt running-off, and improve the product quality and production efficiency of HFW welded pipe. |
