摘要： PROBLEM TO BE SOLVED: To easily and quickly detect an inner volume of a pipe line and a leakage amount by a compact inspection device, and to accurately judge quality of an inspection result.
SOLUTION: A fixed flow rate of inspecting gas is supplied from one end side opening of the inspected pipe line brought into a sealed condition, the flow rate and pressure are detected, and a temperature of the inspecting gas supplied into the pipe line is also detected therein, a pressure detection value. A flow rate detection value, and a temperature detection value are inputted into an arithmetic processing unit, a content volume V
L of the pipe line is computed as V
L =supply flow rate Q×pressurized time Δt/pressure increase value ΔP
2 , based on the pressurized time Δt until the pressure increase value ΔP
2 in the pipe line comes to a set value, and the supply flow rate Q in the period, and then the leakage amount Q
L from the pipe line is computed as Q
L =pressure decrease value ΔP
2' ×pipe line content volume V
L /pressure decrease time Δt', based on the pressure decrease value ΔP
2' after the prescribed pressure decrease time Δt' lapses after an inside of the pipe line is pressurized to the set pressure, and the pipe line content volume V
L computed hereinbefore.
