Discussion on Procurement and Hydro-technological Protection of Gas Transmission Pipeline Project

The authors deeply study and probe into the procurement and hydro-technological protection technique during the construction of gas transmission pipeline project. Taking Lanzhou-Yinchuan Gas Transmission Pipeline Project as an example, an analysis on the process monitoring of control data of pipe material is made and "4-stage controlling method" about the quantity controlling of pipe material is presented. It is pointed out that hydro-technological protection project and environmental protection project are important appurtenant work in pipeline project, in which design and construction quality will directly influence the operation safety of pipeline, therefore, pipeline design and construction companies should lay stress upon it.
