Abstract

PURPOSE:Pipes with high strength and resistance to breakage caused by expansion and contraction, which consists of the hard bended part and the flexible part, is produced by blowing air into a continuous tube consisting of the thick-wall part for the hard bended part and thetthin-wall part for the flexible part which is set in a mold containing the parts for hard bended pipe and flexible pipe.
