摘要
根据Q/SY 1180.4-2015和SY/T 0087.5-2016标准给出的方法,以国外某条长输原油管道为研究对象,收集竣工资料、巡线资料、运维资料、漏磁检测、防腐蚀层检测、阴极保护测试、开挖验证、腐蚀评价和完整性评价等数据,对18类与管道完整性管理相关的数据进行数据对齐,并对主要的管道腐蚀数据进行综合分析。结合管道沿线高程、防腐蚀层补口范围、防腐蚀层绝缘电阻和完整性评价情况,判断并识别出需要积极响应的11处管道漏磁检测内部腐蚀缺陷点、15处管道漏磁检测外部腐蚀缺陷点和7处“双高”管段。针对不同类型的管道缺陷点和管段,提出相应的风险防控措施。
According to the methods given in Q/SY 1180.4-2015and SY/T 0087.5-2016criterion,taking a foreign long-distance crude oil pipeline as the research object,the completion data,in-line inspection data,operation and maintenance data,magnetic flux leakage detection,and corrosion protection layer detection,cathodic protection test,excavation verification,corrosion evaluation and integrity evaluation data were collected.18types of data related to pipeline integrity management were aligned and the main pipeline corrosion data were comprehensively analyzed.Combining with the elevation along the pipeline,the range of the anti-corrosion coating,the insulation resistance of the anti-corrosion coating and the integrity evaluation,totally 11internal corrosion defects in the pipeline magnetic flux leakage test and 15external corrosion defects in the pipeline magnetic flux leakage test that need a positive response and 7 double height pipe sections were identified.For different types of pipeline defects and pipe sections,corresponding risk prevention and control measures were proposed to provide references for the safe operation and integrity management of the pipeline.
