At the same time, a branch pipe with a smaller diameter than the main pipe is installed at the branch connection port at the upper end of the joint body, and in this state, the branch pipe cannot be installed. When assembling the branch pipe, a part of the facing peripheral wall of the branch connection port located on the side is reduced in diameter by pressing and drawing into a flat shape, leaving the part intact, so that the diameter of the part of the wall facing the branch connection port located on the side is reduced, and the diameter of the part is reduced by pressing and drawing into a flat part. The mutual tight surfaces in the combined state, the hole periphery of the through-hole into which the main pipe is inserted, and the abutment surface between the inner circumferential surface of the joint body perpendicular to the through-hole and the outer circumferential surface of the main pipe. Either the main pipe without a branch hole is penetrated through the through hole, and after the above-mentioned process is performed, the branch pipe is welded together with solder. Then, a cutting tool is inserted into the inside of the branch pipe to cut the peripheral wall of the main pipe. The gist of this invention is a method for manufacturing a branch pipe joint, which is formed by drilling and molding a branch hole in the part.

The diameter of the flat shape is reduced by pressure drawing in the flat state, and the joint surfaces of the through-hole, the hole periphery of the through hole, and the abutment surface are collectively soldered, thereby forming the flat shape by pressure drawing. The flat part acts as a rib to increase the rigidity of the joint body, and the branch pipe to be assembled to the branch connection port can be connected with a desired outer diameter smaller than that of the main pipe. This makes it possible to relax restrictions on the tube diameter and expand its range of applications.

Insertion of the main pipe (P) into the through hole (4) by the joint body (1) consisting of a short pipe, and insertion of the branch pipe (Po) into the branch connection port (2).
), the diameter is reduced by pressing and drawing the part of the peripheral wall in the opposite direction of the branch connection port (2), and the contact surface formed between them and the main pipe are reduced. (
Since the hole periphery of the through-hole (4) into which P) is inserted and the abutting surface are individually soldered and formed, the flat part (6) exerts a reinforcing effect as a rib to strengthen the entire joint. In addition to increasing the rigidity of the pipe and increasing its resistance to vibration, it is also possible to connect the branch pipe (po) assembled to the branch connection port (2) with a smaller outer diameter than the main pipe (P) if desired. This is an extremely useful method for manufacturing a branch pipe joint, which can ease restrictions on the pipe diameter and expand the range of applications.
