PROBLEM TO BE SOLVED: To provide air piping in which workability thereof is superior and an air tool can be connected without reducing rigidity of the piping.SOLUTION: A laminated pipe having plasticity in which metal and resin are laminated is arranged in an endless loop manner to construct loop piping, one location at the piping is connected to a main air pipe under a state in which the loop piping is hung horizontally along a ceiling. An air output cheese having a branched part to which an air tool can be connected at an arbitrary location in a piping passage is fixed with the branched part facing down, and the air output cheese is provided with a hanging part for the ceiling at an opposite side outer surface from the branched part. |
