BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a fusion machine for manufacturing a header.

[0002]

2. Description of the Related Art Conventionally, a header is manufactured by alternately connecting a plurality of branch pipe joints A and short pipes B as shown in FIG. In general, in the manufacturing work of this header, it is necessary to accurately set the position and angle of the branch pipe according to the situation of the construction site. Therefore, from the step of dimensioning the allocation of the short pipe B, It is done in the field.

However, the conventional header has the following problems.

A step is formed on the inner peripheral surface of the connecting portion of the branch pipe joint A and the short pipe B, and the step causes a turbulent flow in the transport fluid or a large flow loss of the transport fluid due to friction. Since the fluid is apt to stay near the step on the inner peripheral surface and various bacteria are easily generated, it cannot be used as a pipe for transporting ultrapure water. It is difficult to stably supply the header with high accuracy because a very high technique is required to match the axial centers of the branch pipe joint A and the short pipe B. In order to sufficiently secure the bending rigidity and the pressure resistance, it is necessary to reinforce the connection portion of the branch pipe joint A and the short pipe B tough, so that labor and material cost are required.

Therefore, the applicant of the present invention has invented that a header is manufactured by fusion-bonding a plurality of saddles (short pipes with flanges) to one header pipe (Japanese Patent Application No. 7-9084).

[0006]

However, in such a conventional fusion bonding machine, when a plurality of saddles are fusion-bonded to the header pipe, the pipe clamp is loosened every time the saddle is fused. Since it is necessary to move the header pipe by hand, moving the header pipe in the axial direction also moves in the circumferential direction, and conversely, moving the header pipe in the axial direction in the axial direction. However, there was a problem that the saddle was easily moved and an error was likely to occur in the saddle fusion position.

In view of the above problems, it is an object of the present invention to provide a fusion splicer capable of supplying a highly accurate and stable header.
