- 摘要:
- 在长输管道工程中,管道测径施工过程受到诸多因素影响,有时管道并没有发生异常变形,但测径板仍出现变形和皱褶,显示测径检验结果不合格。为此文章分析了影响测径检验结果准确性的因素,尝试在水压试验完成后第一遍扫水施工时,再对管道进行一次测径工作,这样可以最大限度地避免因清管器皮碗磨损及清管器运行速度过快造成非正常撞击对测径板的损伤,最终验证测径检验结果的准确性。文章就保证和提高管道测径检验准确性的问题提出了一些措施。
Caliper inspection for long-distance pipeline is influenced by many factors. Sometimes there is actually no abnormal deformation of pipeline, but the caliper plate has deformation and goffer and it indicates disqualified results. The factors affecting caliper inspection accuracy are analyzed. It was tried that after the hydraulic test finished and in first water scavenging, another caliper inspection was carried out. Thus the caliper plate damage caused by impact owing to pig leather cup abrasion and pig overquick moving could be avoided furthest. The accuracy of caliper inspection for long-distance could be increased and ensured.2011,5(5): 75-76 收稿日期：2010-10-5分类号：TE973.6作者简介：温涛(1980-),男,山东龙口人,工程师,2001年毕业于苏州城市建设环境保护学院,现从事油气田地面工程建设的施工管理工作.参考文献：
