摘要
分析了20号无缝钢管的室温和低温力学性能,结合显微组织观察、晶粒度统计和断口分析,发现低温低应力工况下服役后20号无缝钢管的力学性能完全符合冷库用液氨管道的使用要求。
the author analyzes the 20th at room temperature and low temperature mechanical properties of seamless steel pipe, combined with the microstructure observation, grain size statistics and fracture analysis, found 20 after he served under the working condition of low temperature and low stress, the mechanical properties of seamless steel tube completely conform to the requirements of the cold storage with the use of liquid ammonia pipeline.
