根据实际工程设计与施工经验,认为低压蒸汽管道设计的重点是合理布置管道走向、管道施工难度控制、管道应力计算、保温、防水。结合实际工程案例,对低压过热蒸汽管道的敷设重点进行了分析。 According to the actual engineering design and construction experience, it is considered that the key points of low-pressure steam pipe design are the reasonable layout of pipelines, difficulty in pipe construction control, pipe stress calculation, heat preservation and waterproofing. Combined with the actual project case, the emphasis of the laying of low pressure overheated steam pipe was analyzed.
