一条压力管道裂纹多发的检验案例分析

Analysis of inspection case of One pressure pipeline crack occurrence

对一个编号为AS-0841的压力管道进行定期检验,发现其泵出口处的管段存在开裂和私自补焊等现象。针对这一现象,结合该管道外部振动和内部湿硫化氢破坏等因素,分析了该管段裂纹多发的原因,并对以后的定期检验工作提出建议。

Periodic inspection of a pressure pipeline numbered as AS-0841 is introduced in this paper. Cracks and self-repairing welding in the pipe at the outlet of the pump are found. In view of this phenomenon, combined with the external vibration of the pipeline and internal wet hydrogen sulfide failure and other factors. The crack occurrence reasons of this pipe are analysed in this paper. Also, suggestions for future periodic inspection are proposed.
