Abstract
PURPOSE: To detect simply and rapidly leak throughout a long range by moving a detection unit.
CONSTITUTION: A part of provided pipe 1 for city gas carrying is cut in both sides of check object part 1a, and temporary pipe 1b for bypass is provided as required to continue fluid carrying, and meanwhile, detection unit 7 is inserted to check object part 1a and is made movable by wire 6, and nitrogen gas supply unit 8 and pressure reduction unit 9 are connected. Then, after city gas exhaustion and nitrogen gas charge for check object part 1a, nitrogen gas supply is stopped to reduce the pipe pressure of check object part 1a, and under this state, take-up unit 5 is used to move detection unit 7. As a result, leak can be detected rapidly with a small labor for check object part 1a extending throughout a long range.
