Abstract
PURPOSE: To simplify the manufacturing process for a bent pipe at an excellent working efficiency so as to reduce the cost, by forming an annular pipe, then by manufacturing plural bent pipes by cutting the annular pipe crosswise.
CONSTITUTION: To manufacture a worked pipe 1, two semicircular-arc shaped annular bodies with bulging 11 are made of metallic plate by pressing etc., the needless peripheral part being cut to form tapered verge 12. These shaped bodies are arranged with their verges 12 placed face to face and are butt welded. Worked pipe 1 of dough-nut shape is cut crosswise into several pieces to form required bent pipes 2. The bent pipe 2 manufactured in this way is welded to the end of a pipe 3 to form one body. Hereby inside diameter D of the bent pipe 2 can be made sufficiently small compared with the diameter (r) of the joint pipe. Because plural bent pipes 2 are manufactured simultaneously, the manufactre is performed simply at excellent working efficiency and with excellent result.
