通过对φ325X8流体管道进行力学性能、化学成分及微观组织分析,确认管道为无缝管道,但管道材质的性能和成份不符合相关标准对20#钢的要求。
Through the mechanical properties, chemical composition and microstructure analysis of φ325X8 fluid pipeline, it is confirmed that the pipeline is a seamless pipeline, but the performance and composition of the pipeline material do not meet the requirements of the relevant standards for 20 # steel.
