Abstract
A method for manufacturing a pipe with a rib, in which a rib portion formed inside a pipe portion includes bent portions in accordance with bending of the pipe portion or a twisted portion in accordance with twisting of the pipe portion, includes drawing out molten metal held in a furnace by using a starter, from a surface of the molten metal, and drawing up the molten metal through a shape defining member defining a sectional shape of the pipe with the rib to be cast, and cooling and solidifying the molten metal passed through the shape defining member and drawn up. The bent portions are formed by moving at least one of the starter and the shape defining member in a horizontal direction. The twisted portion is formed by rotating at least one of the starter and the shape defining member about an axis extending along a vertical direction.
