PROBLEM TO BE SOLVED: To provide a method for giving robust property to leak detection, a piping structure capable of materializing the method and an aircraft with the piping structure.SOLUTION: A piping structure 10 comprises: a pipe 20 that includes a plurality of ducts 21 where gas having temperature higher than temperature in a surrounding atmosphere flows continuously and includes a plurality of couplings 22 for connecting the ducts 21 with each other and that is arranged along an approximately-horizontal direction; and a cover 23 that covers an outer periphery of the pipe 20. The cover 23 defines a plurality of air holes 31 and 32 which allow gas leaked from the pipe 20 to discharge to the outside of the cover 23, at intervals in a length direction of the pipe 20. Each position of at least first air holes 31 respectively corresponding to a plurality of locations 201 where the ducts 21 are connected to each other, out of the air holes 31 and 32, is substantially defined within a range from a two-o'clock position to a ten-o'clock position through a six-o'clock position in a cross-section of the cover 23.SELECTED DRAWING: Figure 2 |
