進工法用管。[Claims for Utility Model Registration] 1. A stepped portion at one end of the pipe, which has an outer diameter one step smaller than the pipe body and has the same outer diameter as the pipe body, and is capable of fitting into the other end of the pipe. The stepped surface formed at the far end of this stepped portion is formed so that it can come into contact with the end surface of the other end of the tube, and the outer periphery of the tube excluding the stepped portion is coated with a resin material having anti-corrosion properties. Characteristic pipes for the propulsion method. 2. The outer periphery of the pipe near the stepped portion, including the step surface, is formed into an annular protective wall portion that has a larger outer diameter than the other end of the pipe covered with a resin material, and the protective wall portion continues to the pipe body. A pipe for use in a propulsion method according to claim 1, wherein the peripheral portion is formed into a tapered surface.
