This article introduced application of digital laser vision technology in several key links during welded pipe manufacturing,including realizing weld tracking,adaptive adjusting welding parameters or angle of driving the strip, measuring coil plate width and edge contour,measuring steel pipe diameter,and automatic inspecting weld profile and defects,etc..

介绍了数字激光视觉技术在焊管制造过程中多个关键环节中的应用，包括实现焊缝跟踪，焊接参数或钢带送进角度的自适应调整，钢板宽度与边缘形状的检测，钢管外径的测量，焊缝成形及缺陷的自动检测等。

During the pipe pushing construction of the parallel steel water pipeline of Beidu-Yanger pipeline project in Ningbo, the pushing force in main pushing power station appeared unusual increasing and the construction had to be interrupted. Through the analytical comparison between theoretical and practical pushing curves as well as the analytical comparison between the tool pipe track and the form map of pipeline resting in soil, it was found that the excessive pushing force in main pushing power station was caused by excessive deviation adjustment angle which enabled the pipeline to over bend in a short distance.

在宁波市北渡－雅戈尔原水D1800mm钢管复线工程顶管施工中，出现主顶动力站顶力异常增大的现象，影响继续顶进施工，文章针对这一情况进行分析研究，通过理论顶力曲线与实际顶力曲线以及工具管所经轨迹与管道在土层中静止时的形态图的分析比较，得出主顶动力站顶力过大是因为在纠偏过程中纠偏角度过大，使管道在短距离内过度弯曲引起的。

The influences of curvature, torsion and inclined angle of cross section of the pipe on the flow characteristics are analysed and studied in the fully developed steady laminar flow of helical square pipe.

借以分析研究了螺旋状矩形管在定常、充分发展的层流流动中，管的曲率、挠率和横截面倾斜角对流动特性的种种影响。

After knowing the structure nature frequency, optimize the structure, such as disposal the point of support, reduce the number of elbow, change the thickness of pipe, setting the dilatant and so on, which offer a basic to avoid resonance.

当知道结构固有频率后，便可以通过优化结构，例如重新布置支点、减少弯头数、改变管的厚度、设置膨胀圈等方法，改变结构的固有频率，为避开共振频率打下基础。

It is important to study the strength of the pipe elbow.

管道弯头的强度研究是个很重要的问题。

In addition, the impact of the size of the calculated value of the resistance water pipe head loss, therefore, should adopt the arrangement of the shortest line, and as little as possible, such as elbow fittings installed, it may consider appropriate with larger diameter water pipes to reduce the flow tube.

另外，影响计算值的大小是吸水管道的阻力损失扬程，因此，宜采用最短的管路布置，并尽量少装弯头等配件，也可考虑适当配大一些口径的水管，以减管内流速。
