焊接检测的文章，请大家帮忙翻译下大概意思~？ longitudinal seams in adjoining lengths of welded pipe shall be staggered and shall be located to clear openings and external attachments. clearance and stagger shall not be less than 1 inch (25 mm). longitudinal seam welds shall be located in the top quadrant of the pipe . 焊接钢管的纵缝安排应保证相邻两钢管焊缝交错并与开孔及外部附件保持一定距离。 交错和保持的距离不得小于1英寸（25mm）。 条件允许时，纵缝应位于管子顶部的1/4圆周内 for testing and venting, each segment of all reinforcing pads for pressure openings shall be provided with two holes drilled and tapped for nominal pipe size (nps) 1/8 inch (3 mm). these holes shall be located 180 degrees apart on one-piece pads. each pad should be proportioned so the diameter of the test hole is not greater than one-third of the pad width. all segments of reinforcing pads for structural attachments shall be provided with one untapped 1/4 inch (6 mm) hole for venting 为保证检测和排气，用于带压开孔的补强圈每块上均须设置两个公称尺寸为1/8英寸(3mm)螺纹孔。 每个补强圈的大小应与直径成比例以保证试验孔的直径不大于板宽的三分之一 每块补强圈上的这些孔应彼此相隔180度。 用于外部附件的加强垫板应每块上带有1/4英寸（6mm)的无螺纹通孔用于排气。 个人意见，仅供参考。 [ ]查看更多
