The gas pipeline used in this project is a gas pipeline with the longest distance, largest pipe diameter and highest transmission pressure in the history of petroleum pipeline construction of China. For the construction of top rank gas pipeline in the world with high standard, high speed and high benefit, the key of specifying production of metallurgical and pipe making enterprises and ensuring quality performance of the steel and steel pipe is to research and formulate a feasible and satisfactory technical Specification for engineering steel and steel pipe with international level. In this paper the author introduces the establishment of the technical specification for West East gas pipeline project, and lays emphasis on the analysis and discussion of principle and method determining major technical indexes related to line pipes for West East gas pipeline. The author also introduces actual material selection of gas pipeline home and abroad, and presents examination and application of the technical specification for West-East gas pipeline.展开更多

The remote sensing technique has the unique superiority to obtain the geographic information. The remote sensing technique is used in WEGTP to interpret comprehensively the information of geology, landform and humane geography along the route of pipeline, and to update the topographic map along the route of Zhengzhou Shanghai section pipeline, and to interpret finely the crossing point of the Nanjing Changjiang river crossing section. Through the overlap of TM image and the DEM, the complicated landform information can be grasped by the three dimensional flight over the section of complicated geography. The application achievements are managed with RS-GIS service system.展开更多
