Abstract

PURPOSE:To obtain a thick pipe efficiently and at a low cost, by forming a cup-like bottomed material pipe, and after that, removing its bottom part, and subsequently, extruding the pipe by inserting a mandrel. CONSTITUTION:A cup-like bottomed material pipe 3 is formed by means of hot Erfurt piercing, etc., its bottom part 3a is cut and removed after cooling, and also a worked part 3' a is formed by reducing the extruding bottom side. Subsequently, a bottomless material pipe 3' is installed on the front of a die 4, and a mandrel 7 installed to a ram head 5' of a hydraulic press, formed in one body with a flange 5, and having the diameter being smaller than the inside diameter of the material pipe 3' is inserted into the inside of the material pipe 3'. Subsequently, hot extrusion of the material pipe 3' is performed in a state that the flange 6 has been pressed against a pipe end 3'b of the material pipe 3'. After that, prescribed finish working such as cutting of the inside and outside surfaces, etc. is performed.
