<p>PROBLEM TO BE SOLVED: To provide a piping groove mating structure and a piping groove mating method capable of easily adjusting centering and spacing of a piping groove part by few field work manhours.SOLUTION: The piping groove mating structure adjusts the centering and the spacing of the groove parts 101c and 101d before butt welding of mutual pipes 101a and 101b suspended so as to be movable in the axial direction, and comprises a plurality of wire hooking parts 102a and 102b mutually arranged at an equal interval in the same number along the circumferential direction in the vicinity of the groove parts 101c and 101d of the two pipes 101a and 101b, and a wire 103 is alternately hooked on the wire hooking part 102a of the pipe 101a and the wire hooking part 102b of the pipe 101b, and both ends of the wire 103 are pulled, and thereby, a distance between the mutual groove parts 101c and 101d is set in a predetermined value required for welding.</p> |
