PROBLEM TO BE SOLVED: To efficiently perform the interior finish work of a resin pipe by eliminating various defects of a method for inserting the resin pipe using a coil pipe. SOLUTION: A pipe closing tool 5 is constituted so as to perform a pipe closing process arranging the pipe closing tool 5, which closes the internal space of a constant length PE pipe having set length to freely divide the PE pipe, on one end side in the PE pipe, a softening process for supplying heated steam to the internal space S1 on the side of a traction tool among the internal spaces of the PE pipe 1 divided by the pipe closing tool 5 to soften the PE pipe, an insertion process for inserting the softened PE pipe 1 in existing piping and a pipe connection process for taking the pipe closing tool 5 out of the PE pipe 1 inserted in the piping and connecting one end 1b of the PE pipe 1 and one end of the PE pipe 1 separate from the PE pipe 1 inserted in the piping by butt fusing. |
