Specification of X80 line pipe for 2nd West-East Gas Transmission Pipeline Project has referenced in context to the latest edition of international standards like ISO 3183 and API Spec 5L. Some complementarities have been made to achieve the balance between the safety and economy of the high-pressure gas transmission system, such as in the chemical content, tensile strength, arrest toughness, etc. The line pipe specification was analyzed combining with the properties of the practically manufactured pipe in this paper. It’s shown that the pipe manufactures have established the steel design process for X80 pipes and the pipeline designers have been developing the design method of high-pressure gas pipelines with X80 line pipe. As the collaboration between the pipe manufactures and pipeline designers, X80 line pipes are applicable in 2nd West-East Gas Transmission Pipeline Project commercially.
