PIG FOR LINING PIPE INSIDE AND METHOD FOR LINING PIPE INSIDE

摘要

PROBLEM TO BE SOLVED: To provide a pig for lining the inside of a pipe with which an un-cured resin layer in a desired thickness can be formed with scarce defects such as pin holes and with which a fluid for pig movement is prevented from leaking forward in the pig movement direction through the un-cured resin between the pig and the inner face of the pipe.

SOLUTION: The pipe inside lining pig is for applying an un-cured lining resin C packed in the front side in the movement direction to the inner face of a lining object pipe 1 for forming a lining layer E in the inner face of the pipe by moving along the longitudinal direction of the pipe in the inside of the pipe and a pig body B is made to be cylindrical shape closed at the front end part in the movement direction and having an opening 5 in the rear end part.
