Abstract: According to the basic technology parameters stated in the feasibility study report of Sino-Russia Gas Transmission Pipeline Project, this paper presents the gas transmission technology plan possibly adopted for the future Sino-Russia Gas Transmission Pipeline Project through hydraulic calculation necessary to the transmission technology, calculation on wall thickness of X70 and X80 and capital comparison and analysis. To meet the needs of the pipeline construction, the suggestion about applied study on X80 grade pipe steel is put forward.
