摘　　要：结合广东省天然气管网站场干燥整个流程进行探讨,并结合干燥数据进行讨论,指出干燥过程中干空气吹扫与抽真空结合使用时时间节点的优化。通过分析近年来国内外天然气管道干燥施工实例,阐述了真空干燥的优势、施工原理及施工流程,同时提出工艺复杂的天然气管道干燥时建议采用干空气吹扫与真空干燥相结合使用。Combining with the whole process of station drying for gas pipeline network in Guangdong province and the drying data,the optimization of timing point with the combination of the dry air purging and vacuum drying during the drying is point out. Through the analysis of drying construction examples for gas pipeline at home and abroad in recent years,the advantages of vacuum drying,construction principle and construction process are described. Meanwhile,it suggested to use the dry air purging and vacuum drying for the gas pipeline drying at the complicated process.
