| 摘 要： | 为及时掌握长庆气田地面集输管道腐蚀状况,近年来对12条管道防腐层开展了电流衰减法(PCM)检测和开挖检测,检测发现防腐层外观完好为90.4%,少许破损为5.2%,破损严重为4.4%。在此基础上,分析了防腐层破损不合格的主要原因。建议在后续的气田防腐设计时,优先采用性能优异的防腐材料、严格执行防腐层施工技术要求、加强乙方施工管理,以确保管道防腐措施效果。 |

| Abstract: | To mastering the corrosion status of surface transport pipeline in Changqing gas field,anticorrosion coating of 12 pipelines were inspected by pipeline current map(PCM) and excavation in recent years.It was found that the proportion of coating appearance in good condition account for 90.4%,the proportions of coating appearance with little damage and seriously damaged account for 5.2% and 4.4% respectively.On this basis,the main reasons of unqualified anticorrosion layer were analyzed.The proposals of anticorrosion design were put forward in the future gas field,including optimal selection of anticorrosion materials,strict implementation of the technical requirements of anticorrosion coating construction,strengthen construction management of party B,to ensure the anticorrosion effectiveness of pipeline. |
