摘　　要：文章通过分析钢铁行业煤气压力管道设计最低使用温度,提出了在低温环境条件下管道材料如何选择和一些注意事项。钢铁行业煤气管道通常管径大、压力低,不属于压力管道。随着新工艺和新技术的发展,一些压力高于0.1 MPa的煤气管道就属于压力管道。在设计选材时,需要按照压力管道规范进行设计。在严寒地区,当管道设计最低使用温度低于-20℃时,要考虑低温条件下压力管道选用材料的适用性。In the paper,it is proposed how to select the pipeline material and some matters needing attention in low temperature environment condition by analyzing the lowest design operating temperature of gas pressure piping in the iron and steel industry.The gas pipe in the iron and steel industry is usually with large pipe diameter and low pressure,so it is not pressure piping.With the development of new technologies,some gas pipes with pressure higher than 0.1 MPa are pressure piping.The design of material should be based on the pressure piping code.In the severe cold area,when the lowest design operating temperature of pipe is lower than-20℃,the applicability of materials selected for pressure piping in low temperature conditions shall be considered.
