埋地钢质管道完整性检测与评价

Integrality Inspection and Assessment of Buried Steel Pipeline

管道完整性检测与评价是近年来出现的新事物。文章在简要论述了埋地钢质管道完整性检测方法及原理的基础上,通过对某埋地钢质管道实施完整性检测,包括外防腐层、阴极保护有效性、杂散电流干扰以及管道本体检测等,实现了对管道的完整性评价。实践表明,该检测评价工作可为管道的运行、维修维护及安全管理提供科学依据。

Based on brief introduction to the principle and method of integrality inspection and assessment for buried steel pipelines,this paper describes further the integrality inspection of a buried steel pipeline in aspects of anticorrosion efficiencies of external layer and cathodic protection,stray current interference and pipeline body.The implementation of pipeline integrality assessment is also presented.The practice shows that the inspection and assessment work can provide a scientific foundation for pipeline operation,maintenance and repair as well as safety management.
