一、绪言在核能管道及再处理设施的管道工程中,用弯曲加工的钢管替代焊接式管接头,因其减少了焊接部位,有效地降低了施工费用并缩短了施工周期。所以在普通钢种的中厚壁配管工程中得到广泛使用。虽然普遍希望能将感应加热弯曲技术应用于薄壁不锈钢钢管的弯曲加工 I. INTRODUCTION In the pipeline engineering of nuclear energy pipelines and reprocessing facilities, the use of curved steel pipe instead of welded pipe fittings has reduced the welding area and effectively reduced the construction cost and shorten the construction period. Therefore, the ordinary steel in the thick-walled piping project has been widely used. Although it is generally hoped that the induction heating bending technique can be applied to the bending of thin-wall stainless steel tubes
