长输天然气管道焊接裂纹成因及其控制分析

Causes and Control Analysis of Welding Cracks in Long-distance Natural Gas Pipelines

天然气借由长输天然气管道被输送到千家万户,从某种程度上来说,管道的整体质量关系着天然气运输的安全性和稳定性,但受不可控因素影响,天然气管道在运行过程中容易出现各种各样的问题,这就要求我们在管道焊接过程中,要做好每个施工环节的对接工作,提高管道焊接质量,保障管道运行的稳定性。基于此,本文就对长输天然气管道焊接裂纹成因及其控制策略进行了一个较为详细的概述。

Natural gas is transported to millions of households through long-distance natural gas pipelines.To some extent,the overall quality of the pipeline is related to the safety and stability of natural gas transportation,but due to uncontrollable factors,and ensure the stability of the pipeline operation.Based on this,this article gives a more detailed overview of the causes of welding cracks in long-distance natural gas pipelines and their control strategies.
