Abstract:  Large-diameter steel pipes for offshore wind power generation will have multiple deformation problems in construction. The deformation area must be strictly controlled， and targeted technical measures must be adopted to maximize the quality of steel pipes and avoid a series of problems caused by scrapping or failure to deliver materials. The deformation control of large-diameter steel pipes should consider a complete set of planning paths， and a very comprehensive technical control should be done in each link of manufacturing， transportation and storage， so as to avoid large deformation production problems in one of the links. It is an important prerequisite to form a process plan， reduce costs and control the construction quality by paying attention to the trend of controlling its deformation， fully considering the equipment capacity and production capacity， selecting the technological means that can maximize the quality and highest efficiency of steel pipe construction， improving the construction level and ensuring the effective control of its deformation. Based on this， this paper discusses and analyzes the application of construction technology for steel pipe deformation control for reference.
