<p><P>PROBLEM TO BE SOLVED: To stop gas leakage from a pipe wall in a short time period, and continuously keep the state. <P>SOLUTION: An uncured resin layer attached part is formed by coating the photo-curable resin composition 2 to one side surface of a transparent resin film 1 in advance. The uncured resin layer attached part is attached to the gas leakage point 4 of a pipe outside wall in the gas piping 3 to form the coated part. While the transparent resin film 1 is pressed to the pipe outside wall side from the outside to keep the airtightness, light is applied to the coated part through the transparent resin film 1 to cure the photo-curable resin composition 2. Thus, the seal part is formed to the gas leakage point 4 in the pipe outside wall. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
