DEVELOPMENT AND APPLICATIONS OF PIPELINE STEEL IN LONG-DISTANCE GAS PIPELINE OF CHINA

摘要：

　　In past decades,with widely utilizing of Microalloying and Thermal Mechanical Control Processing(TMCP)technology,the good matching of strength,toughness,plasticity and weldability on pipeline steel has been reached so that oil and gas pipeline has been greatly developed in China to meet the demand of strong domestic consumption of energy.In this paper,development history of pipeline steel and gas pipeline in china is briefly reviewed.The microstructure characteristic and mechanical performance of pipeline steel used in some representative gas pipelines of china built in different stage are summarized.Through the analysis on the evolution of pipeline service environment,some prospective development trend of application of pipeline steel in China is also presented.
