针对目前新建油气管道可能存在的缺陷类型, 根据验收标准及可行的检测技术的分析, 提出了“22112”检测及评价方法。采用试压前后变径、弱磁、漏磁检测等多种技术, 建立了管道本体质量验收的系列标准。通过及时排查和发现管道的缺陷, 消除管道投产运行前潜在的危险, 做好管道建设与运行的质量交接, 为提高管道质量安全打下基础。

In this paper, the existing defects, acceptance criteria and feasible detection technology of the new oil gas pipeline are analyzed. The method of detection and evaluation named 22112 is proposed. A series of standards for checking the quality of the pipeline are established by the varying diameter before and after applying pressure to the pipe, the weak magnetism and magnetic flux leakage test. In order to improve safety of the pipeline, it is necessary to investigate and discover defects of pipeline timely and eliminate the potential and unacceptable risk or danger before running, meanwhile the handover of quality and construction of pipeline must be ensured.
