    Abstract：In order to solve the problem that blind ends and corners of pipeline network cannot be dried completely by using conventional dry air and dew point repeatedly rebounds after drying, improved is the drying process and adopted is the vacuum drying technology for drying pipeline network. In Yulin Gas Compressor Station of Shaanxi-Beijing Gas Pipeline, the vacuum drying technology plays a very important role in instation pipeline network drying. Collected are some important process parameters of pipeline network drying, drawn are pressure-time curves of the drying system, analyzed is the drying effect in combination with the drying process and systematically expounded are the working principle, construction process, drying effect and construction control key points of the vacuum drying technology, which will provide theorial and technical supports for further popularization and application of the vacuum drying technology in compressor station pipeline network drying.
