NAIL-PENETRATION INSPECTION METHOD FOR PIPING

PROBLEM TO BE SOLVED: To provide a nail-penetration inspection method for a piping with which whether a nail is penetrated through the piping or not and nailing point are detected in a simple manner. SOLUTION: A piping space 3 is formed between a floor slab 1 and a particle board 2, and a flexible piping 3 for gas is assigned in the piping space 3. A veneer 6 is fixed to the top of the particle board 2 with a nail 7. A tip part 7b of the nail 7 is protruded to the piping space 3. In this constitution, an end part 9a of one lead wire 9 of a tester 8 is connected to an end part 4a of the piping 4 with a clamp, etc. Then, an end part 10a of the other lead wire 10 of the tester 8 is brought into contact with a bead part 7a of the nail 7, in order. And, relating to the nail 7 whose continuity is detected, it is decided that the nail is brought into contact with the piping 4 or penetrated through the piping 4.
