1.概述螺旋焊管制造业是将钢带按一定的螺旋线的角度卷成管,然后将管缝焊接制成钢管,当钢管长度达一定长度时(8~12m),需要将钢管从连续的生产线上切断。由于钢管的生产速度较慢(约1.5m/min),所以一般采用氧乙炔火焰切割或等离子切割。2011年公司从德国引进一套螺旋焊管预精焊机组,该机组生产的螺旋焊管具有管径大、壁厚大、材质高、生产速度快 1. Overview Spiral welded pipe manufacturing is the strip at a certain angle of the spiral into a tube, and then the pipe seam welding made of steel, when the length of the pipe up to a certain length (8 ~ 12m), the need for steel from the continuous Cut off the production line. Due to the slow production of steel pipe (about 1.5m / min), so generally oxyacetylene flame cutting or plasma cutting. In 2011, the company introduced a set of pre-welded spiral welded pipe welding machines from Germany. The spiral welded pipe produced by this unit has the advantages of large diameter, large wall thickness, high material quality and fast production speed
