- 摘要:
- 油气长输管道在经过丘陵、冲沟、河流等地形起伏段时,常常会遇到弯管角度的测量和计算问题,而且弯管角度测量及计算的准确与否,直接影响到下一道工序的施工质量。文章分析了弯管角度测量在长输管道施工中的重要性,着重介绍了弯管角度的测量计算方法—同坡法和异坡法,并通过实例说明了该方法的具体应用,强调了实际测量需注意的问题。
Measurement and calculation of pipe bending angles are often needed as long-distance oil and gas pipelines crossing through hill, gully or river, and their accuracies affect the quality of following working procedure. This article analyzes the importance of measuring pipe bending angles in the construction of longdistance pipeline, with an emphasis on two measurement and calculation methods of pipe bending angles, i.e.the same slope method and the different slope method. The practical application of the methods is explained through one example, and some problems for attention in practical measurement are stressed.2012,3(3): 77-78 收稿日期：2011-3-12DOI：10.3969/j.issn.1001-2206.2012.03.024作者简介：闫潇瀚(1974- ),男,辽宁盘锦人,工程师,1999年毕业于大庆石油学院建筑工程专业,现从事石油天然气地面建设工作.参考文献：
