    Application of Coil-preparation Stand to Manufacture of Spiral Welded Pipe

    • 摘要: 介紹了預(yù)開(kāi)卷設(shè)備在螺旋縫焊管機(jī)組中的應(yīng)用情況，包括預(yù)開(kāi)卷的工作原理、工作過(guò)程、常見(jiàn)問(wèn)題的分析及解決措施。預(yù)開(kāi)卷技術(shù)應(yīng)用在螺旋縫焊管的鋼卷準(zhǔn)備階段，可大大縮短鋼板對(duì)頭時(shí)間，同時(shí)提高螺旋縫焊管用鋼板的對(duì)頭焊質(zhì)量，適用于大壁厚、大直徑、高鋼級(jí)螺旋縫焊管的大批量生產(chǎn)。

       

      Abstract: Described in the paper is the application of the coil-preparation stand to the spiral welded pipe production line, involving the work principle, operation process, and analysis and fixing of common problems, etc.When the pre-uncoiling technique is used at the coil preparation stage of manufacturing process for the spiral welded pipe, the steel plate butting time is tremendously reduced, and meanwhile the butt welding quality is improved.This technique is suitable for massive production of heavy-wall, large-sized and hi-grade spiral welded pipes.
