Manufacturing process for offshore wind power foundation steel pipe pile

The invention discloses a manufacturing process for an offshore wind power foundation steel pipe pile. The manufacturing process comprises the following steps of pipe joint blanking, pipe joint grooveprocessing, pipe joint rolling formation, pile body top flange assembling, pipe joint splicing and anticorrosive coating painting. According to the manufacturing process, from material selection, blanking to manufacturing process of steel plates for the steel pipe pile, the roundness and straightness of a pile body are detected and adjusted at any time, and the welding materials and welding processes are strictly controlled. In addition, the coating process of an anticorrosive coating is strictly carried out, so the impact resistance of the steel pipe pile can be effectively improved, it is guaranteed that a pile foundation is driven into a soil layer smoothly, and the corrosion resistance requirement of the steel pipe pile can be met. 本发明公开了种海上风电基础钢管桩的制作工艺，包括以下步骤：管节下料、管节坡口加工、管节卷制成型、桩体顶部法兰装配、管节拼接及防腐涂层涂装。本发明的制作工艺，
