PROBLEM TO BE SOLVED: To improve welding workability of a slide spacer and stabilize the welded quality in a device for line up of pipes regulating positional deviation of parallelly adjacent pipes. SOLUTION: Parallelly adjacent pipes 3 are connected to each other through a slide spacer 11, and connection parts 12 and bent plate parts 13 are integrally formed by the slide spacer 11. The slide spacer 11 is welded to the adjacent pipes 3 to be point-symmetrical respectively. A welding bevel end is formed between the connection part 12 and the pipe 3 in a state that the bent plate part 13 having a curved face engaged with the external face of the pipe 3 is positioned on the pipe 3 and further, a fitting groove 9 to which the connection part 12 of the slide spacer 11 adjacently positioned between the connection part 12 and the pipe 3 can be fitted, is formed. |
