It is preferable that bushings 72 and 74 and the like are provided on the support plate 24 and the flange support 40 that are movably coupled to the support 70.

The reason why the support plate 24 is movable is that the support position is set and stably supported depending on the length and type of the pipe, such as when the length of the pipe 100 is short.

Next, the flange pressurizing device 80 is configured such that the operator can rotate the pressing handle 82 to move the flange 200 in the pipe direction so as to fit the flange 200 around the pipe 100 .

In this manner, when the pipe 100 is provided with an adhesive member or the like, the handle 85 of the flange pressurizing device 80 is rotated to gradually move the flange supporting body 40 in the direction of the pipe 100. At this time, the flange support body 40 moves toward the pipe 100 along the support stand 70.

When the flange support 40 continues to move, the flange 200 mounted on the flange clamp 50 begins to fit around the pipe 100 and moves further. When the flange support 40 moves by a predetermined length, Stop.

In this state, when a predetermined time has elapsed, the adhesive member is hardened and the flange 200 is coupled to the end of the pipe 100 and fixed.

Of course, when the flange 200 is coupled to the end of the pipe 100, the pipe 100 and the flange 200 coupled to each other are directly separated from each other by the pipe clamp 30 and the flange clamp 50, It is also possible to make it hard.

When the pipe 100 and the flange 200 are made of a metal material, the flange 200 and the pipe 100 may be attached to the pipe 100 and the pipe clamp 30, It is also possible to weld the flange 200 in a state where the flange 200 is directly coupled.

As described above, it is preferable that the pipe and the flange are combined using the apparatus of the present invention, and then the pipe and the flange are attached or welded to each other by a known method according to the material and the operating conditions.

The same constituent parts as those of the above-described embodiment are denoted by the same reference numerals.

The second embodiment is configured to commonly use the pipe 100 and the flange 200 of various sizes through the flange clamp 50A. That is, referring to FIG. 8, the pipe 101 and the flange 201, the relatively large diameter pipe 102, and the flange 202 are connected to each other.
