<P>PROBLEM TO BE SOLVED: To provide technique capable of reliably inspecting air-tightness of piping. <P>SOLUTION: A piping inspection device 1 for inspecting air-tightness of piping 6 includes: a tube 2 to be put through the piping 6; an air-tight bag 3 connected to one end of the tube 2 to communicate with the tube 2 and expanded by compression air to obtain air-tightness in the piping 6; a bag pressurization device 4 connected to the other end of the tube 2 to communicate with the tube 2 and pressurizing the inside of the air-tight bag 3 with compression air; and a pipe pressurization device 5 in which the tube 2 is put through and connected to the insertion end of the piping 6, and pressurizes the inside of the piping 6 with the compression air. <P>COPYRIGHT: (C)2013,JPO&INPIT |
