<p><P>PROBLEM TO BE SOLVED: To provide a synthetic resin pipe provided with, at both ends of a pipe body having flexibility, joint parts attachable to another pipe body although the pipe body is formed out of an olefinic resin without causing an adverse effect due to a plasticizer but difficult to be attached to another pipe body. <P>SOLUTION: This synthetic resin pipe has a structure wherein, on an outer peripheral surface of the thin pipe body 1 formed of the olefinic resin and having flexibility, a reinforcing spiral projection 2 made of a rigid vinyl chloride resin and formed by embedding an inner layer material 2b formed of an olefinic resin and fused integrally with the pipe body 1 is arranged; and, on outer peripheral surfaces at both ends of the pipe body 1, cylindrical joint parts 3, 3 made of a rigid vinyl chloride resin, respectively provided with inner layer materials 2b formed of an olefinic resin and fused integrally with both the ends, and each having a certain thickness are arranged. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
