摘要
ILI(in-line inspection)管道在线检测对油气输送管道安全可靠运行至关重要。设计开发了一种全新的基于螺旋测量原理的主动螺旋管道测量装置,该装置能够自主生成管道测量螺旋线,整合了位移传感器和角度传感器,进行了管道测量对比实验以及管道缺陷检测实验;实验数据采用MATLAB处理,反演出管道内壁模型,通过对管道内壁模型的分析来判断管道内部的情况。实验证明了分度式主动螺旋测量方法的可行性,通过对比实验分析了分度式螺旋测量与普通螺旋测量的区别,实验结果表明:该方法描述管道内壁的三维模型更精确,能被管道机器人或管道猪牵引进行测量作业。特别对于微小管径管道、非管道猪管道有一定的应用前景。
The in-line inspection（ILI） technology plays an essential role in oil and gas pipelines＇ safe operation.This paper designs a novel active helical pipeline measurement device based on helical measurement principles,which can control its own helical motion actively. We integrate the measurement device with a distance sensor and an angle sensor and then conduct several comparative experiments and experiments on defect inspection. The inner wall models of a pipeline are retrieved by using the MATLAB software and the experiments＇ data. The experimental results show that the measurement device is feasible,and the comparative experiments show that the measurement device is different from conventional methods. The results also prove that the circumference division active helical pipeline measurement device is more accurate and can be trucked by PIGs or pipe robots,being able to be applied to micro-pipelines or unpiggable pipelines.
