Q235B螺旋管
(1)原材料即带钢卷,焊丝,焊剂。在投入前都要经过严格的理化检验。
(2) 带钢头尾对接,采用单丝或双丝埋弧焊接,在卷成钢管后采用自动埋弧焊补焊。
(3) 成型前,带钢经过矫平、剪边、刨边,表面清理输送和予弯边处理。
(4) 采用电接点压力表控制输送机两边压下油缸的压力,确保了带钢的平稳输送。
(5) 采用外控或内控辊式成型。
(6) 采用焊缝间隙控制装置来保证焊缝间隙满足焊接要求,管径,错边量和焊缝间隙都得到严格的控制。
(7) 内焊和外焊均采用美国林肯电焊机进行单丝或双丝埋弧焊接,从而获得稳定的焊接规范。
(8) 焊缝经过在线连续超声波自动伤仪检查,保证了100%螺旋焊缝无损检测覆盖率。
(9) 采用空气等离子切割机将钢管切成单根。
(10) 切成单根钢管后,每批钢管头三根要进行严格首检制度,确保制管工艺合格后,正式投入生产。
(11) 焊缝上有连续声波探伤标记的部位,经过手动超声波和X射线复查。
(12) 带钢对焊焊缝及与螺旋焊缝相交的丁型接头的所在管,全部经过X射线电视或拍片检查。
(13) 每根钢管经过静水压试验,压力采用径向密封。试验压力和时间都由钢管水压微机检测装置严格控
制。试验参数自动打印记录。
(14) 管端机械加工,使端面垂直度,坡口角和钝边得到准确控制。
Q235B螺旋管的特点
直缝焊管生产工艺简单,生产效率高,成本低,发展较快。螺旋焊管的强度一般比直缝焊管高,能用较窄的坯料生产管径较大的焊管,还可以用同样宽度的坯料生产管径不同的焊管。但是与相同长度的直缝管相比,焊缝长度增加30~100%,而且生产速度较低。因此,较小口径的焊管大都采用直缝焊,大口径焊管则大多采用螺旋焊。
