摘要
海洋石油平台立管在陆地预制安装后,需要使用曲屈探测器清理管道内杂质同时通过测量板外观损坏情况判断管道内径是否满足相关规范要求或焊道处是否有焊瘤等不合格的凸起点。在陆地立管通球过程中,除去立管焊接质量问题,有其他各项因素导致通球失败,不仅严重影响施工进度而且给业主方留下负面印象。本文叙述各种常见通球问题及其原因进行归纳整理,并提出合理可行的解决方案。
After platform riser is installed, the inner dirt of riser needs to be cleaned up by buckle detector. Meanwhile, it will be determined if the pipe diameter meets the related criteria or if the welds are unqualified through visual inspection of the gauging plate. Usually, besides the reason of welding, some other factors also lead to fail during onshore gauging, which can seriously reduce the construction progress and increase the construction cost. In this paper, common construction problems of onshore riser pigging were summarized as well as their causes, and a reasonable and feasible solution was put forward.
