At present, the four major pipelines of supercritical unit adopt imported product, which brings a series of problems, such as high cost, long purchasing cycle, lack of supervision and control of the pipe manufacturing quality, causing increase of power plant construction costs, long construction period, quality defects before site installation inspection, etc. Through analysis of the chemical composition and performance index of the four major pipelines manufactured by domestic steel mills and survey of the condition of domestically manufactured four major pipelines, this paper provides advice for the localization of four major pipelines for a 350MW power plant unit.
