PIPE LINING METHOD FOR NUCLEAR FACILITY PIPE

摘要

PROBLEM TO BE SOLVED: To provide a pipe lining method for a nuclear facility pipe using a cold-setting pig lining material, capable of shortening hardening time and forming a lining layer having a high glass-transition temperature after hardening.SOLUTION: A pipe lining method of the present invention is a method of forming a lining layer on an inner surface of a nuclear facility pipe, comprising: a coating step of forming the lining layer on the inner surface using a cold-setting pig lining material and a pig; and a hardening step of feeding a fluid containing a radioactive material into the pipe and hardening the lining layer.SELECTED DRAWING: None
