<p>PROBLEM TO BE SOLVED: To connect piping with excellent workability without using a flange even for piping in a state of being fixed such as an underground piping. SOLUTION: A stretched vinyl chloride resin pipe 2 stretched and molded along a peripheral direction in advance and having an inside diameter larger than an outside diameter of the piping 1 to be connected is used, and the stretched vinyl chloride resin pipe 2 is inserted and arranged in a connecting part of the piping 1. An adhesive agent 3 is coated on at least one of an outer peripheral surface of an end part of the piping 1 and an inner peripheral surface of the stretched vinyl chloride resin pipe 2. Then, only the stretched vinyl chloride resin pipe 2 is heated. Thus, the stretched vinyl chloride resin pipe 2 is shrunk and the piping 1 is connected.</p> |
