在直缝焊管的生产工艺中,成型方法对焊管质量有重要影响。为了不断提高焊接速度及市场对焊管品种规格的需求,焊管生产厂对成型方法和孔型设计的要求越来越高了。中小直缝焊管的辊式成型分类,按成型过程中带钢边缘的横向运动轨迹分,有圆周弯曲法、边缘弯曲法、中心弯曲法、组合弯曲法等;按成型辊的排列方式分,有一般连
In the production process of the longitudinal welded pipe, the forming method has an important influence on the quality of the welded pipe. In order to continuously improve the welding speed and the market demand for pipe varieties, pipe manufacturing plant on the molding method and the hole design requirements are getting higher and higher. Small and medium-sized longitudinal welded pipe roll forming classification, according to the forming process of the strip edge of the lateral trajectory points, there are circumferential bending method, the edge of the bending method, the center bending method, the combination of bending method; according to the forming roller arrangement, there are General even
