摘　　要：文中从施工验收标准适用性分析开始,针对安装中的一些环节,如材料验收,焊接控制,管道补偿器、阀门、防潮管安装,疏水装置的设置,穿越工程的实施,管沟开挖以及暖管、吹扫等,分别阐述了相应的质量控制要求。此外,还提出了牺牲阳极在直埋蒸汽管道中应用的局限性,为此类管道的安装提供了参考。This paper begins with an analysis of construction acceptance standard applicability, and then expounds some quality control requirements according to some of the installations ,such as material inspection,welding control,piping compensa- tors and valves and moisture drainage pipe installation, crossing engineering construction, trench excavation, steam purge and warming pipe, etc. Besides, it raises the limit of use of sacrificial anode in directly buried steam pipeline and airs our corresponding views. It can be used as a reference for the installation of such pipes.
