Abstract

Abstract: The shape features of the steel bifurcated pipe and the weldability of 15MnNbR vessel steel were introduced. The manufacturing process of special shape steel bifurcated pipe suitable to ultra high water head and its quality control strategy were analyzed. The technical difficult points and control countermeasures of manufacturing of steel bifurcated pipe in Duodihe Hydropower Station by using 15MnNbR vessel steel were expounded.
