The curved pipe section (1) of the above-mentioned R-shaped pipe is laid by joining three pipes, and the corresponding curved pipe (gb) is symmetrical with respect to a virtual plane perpendicular to the pipe axis. It is constructed by joining a plurality of nine short pipes (4) cut by a pair of virtual planes inclined at 111 g.

Even when the pipe is bent in a letter shape, the bent pipe (2b) corresponding to the O-bent pipe part (lb) can be constructed by suitably adjusting the position of the short pipe (4) around the pipe axis and joining it. .

At this time, all of the short pipes (4) may be inserted from one of the vertical shafts, or an appropriate number may be inserted from the vertical shafts on both sides. When the tube axes reach the position, the positions of the pipe axes are mutually adjusted so that the pipe fittings butt up, and the orchid is aligned in accordance with the curved pipe section (lb) of the existing pipe as shown in Figures 1 and 2. The piping in the curved pipe section (1k) is completed by constructing a nine-curve pipe (2b) and then joining the pipe fittings together. The piping in the straight pipe W (IIL) is completed by joining the straight pipes (3) through suitable pipe joints.The joint structure of the short pipes (4) is as shown in Fig. 4. , 40 was conceived in which seven inner flange (5) were provided protruding from the inner periphery of both ends of the short pipe (4), and the inner seven flange (5) facing each other were fastened from inside the pipe with bolts and nuts (6). It will be done. Sealing performance is ensured by inserting a gasket between the inner 7 langes (5) or by forming an annular groove on one side and attaching a rubber ring to this to create a metal touch type 07 lange joint. can do. In addition to the short tube (4) having both end faces sloped, it is also possible to use a short pipe (4) having only one end face sloped as shown in FIG.
