Abstract

PURPOSE: To form the shoulder part being effectively reinforced in the inner surface of the pipe blank, by inserting and fixing the reinforcing pipe in to the pipe blank, and by integrally forming the desired shoulder part at important point.
CONSTITUTION: The reinforcing pipe 2 of diameter slightly smaller than the inner diameter of the pipe blank 1 is inserted into the important point of the pipe blank 1, and the diameter of the pipe blank 1 is a little shrunk by the ironing work or the like, in order to fix the reinforcing pipe 2 to the required position. Next, the shoulder part 3 is formed at the required point of the pipe blank 1 by the swaging work, etc. Hereby, the reinforcing pipe 2 is also provided with the shoulder part 4 under the condition being tight contacting with the inner surface of the pipe blank 1, and the perfectly integrated double pipe is formed. According to this method, the requisitely reinforced pipe with irregular diameters is manufactured.
