Pipeline steel refers to a kind of steel with special requirements used for transporting oil, TRQ and other pipelines. According to the thickness and subsequent formation, it can be produced by hot tandem mill, Steckel mill or medium and heavy plate mill, and formed into large-diameter steel pipes by spiral welding or UOE straight seam welding.
Introduction: pipeline transportation, railway transportation, highway transportation, waterway transportation and transportation are listed as the five major modern transportation modes. From the beginning of industrial pipelines to now, the construction of oil and gas pipelines has experienced nearly two centuries of development. The production and application of pipeline steel in China started late, and there was no real production of pipeline steel before 1985. However, in recent years, the research, development and application of pipeline steel in China have been developed. Driven by major pipeline projects such as the western pipeline, the west east gas pipeline and the second west east gas pipeline, the production and application of X60, X70 and X80 pipeline steel have been completed successively, and the research results of X100 and X120 have been obtained
