浅谈长输管道焊口防腐施工的质量控制

Discussion on Quality Control of Anticorrosion Construction of Long Distance Pipeline Welded Junction

随着我国长输原油管道线路施工建设越来越大规模化,相应的防腐工作将变得越来越重要。由于大部分的长输管道都是使用成品管进行施工建设,这些成品管在出厂前就已经进行过防腐处理,只需要运送到现场进行焊接安装即可,所以能够导致长输管管道出现腐败问题的往往来自管道接口处。为了有效地保障长处管道良好的防腐质量,本文将对长输管道焊口防腐施工的现场质量控制工作进行适当的讨论,通过施工前准备工作、施工过程质量保障工作以及后期的质量检测工作三个层次的分析,希望能够为业界人士提供一些经验参考。

with the large-scale construction of long-distance crude oil pipeline in China,the corresponding anti-corrosion work will become more and more important.As most of the long-distance pipelines are constructed with finished pipes,these finished pipes have been treated with anti-corrosion before leaving the factory,and they only need to be transported to the site for welding and installation.Therefore,the corrosion problems of long-distance pipeline often come from the pipeline interface.In order to effectively guarantee the good anti-corrosion quality of long-distance pipeline,this paper will discuss the field quality control work of long-distance pipeline welding joint anti-corrosion construction.Through the analysis of preparation work before construction,quality assurance work in construction process and quality inspection work in later stage,it is hoped to provide some experience reference for the industry.
