摘要
Provided are a seamless bent pipe constituted by a bent section and straight pipe sections on both ends of the bent section, with the inside diameter at each pipe end portion being larger than the inside diameter of the bent section, and a welded component comprising a seamless bent pipe and a seamless straight pipe at one or each end of the seamless bent pipe, with the end of the seamless straight pipe to be welded to one or each end of the seamless bent pipe having the same inside diameter as the inside diameter of the seamless bent pipe, as well as methods of manufacturing them. As a result, elements suited for use in pipelines can be obtained, without unnecessarily increasing the wall thickness of the seamless bent pipe and without internal machining of the pipe end portions of the seamless bent pipe after the manufacturing thereof.
