大直径高压钢管瓦片整张卷制技术及应用OA

Because the high strength steel pipe of the high pressure pipe under the regulator well of a pumped storage power station needs to withstand the impact of high-speed water flow and the corresponding head pressure,in order to ensure the manufacturing quality,the process of reducing the welding joint is adopted in the process stage,and the pipe section is made of whole steel plate with only one longitudinal joint.This paper mainly introduces the key process technology based on the manufacturing technology of large diameter high pressure steel pipe in the power station.The practice of this project has accumulated rich experience for the production of large pressure steel pipe in the work area.
