製法を要旨とするものである。[Means for Solving the Problems] In order to achieve the above object, the present invention provides a branch pipe joint for connecting a main pipe and a branch pipe, in which a main pipe having a branch hole in a peripheral wall portion is connected to a diameter of the circumferential side. It is made of a short pipe bored in the direction of the main pipe and is inserted into the through-hole of the joint body having a larger diameter than the main pipe and the branch pipe, and is inserted into the hole periphery of the through-hole and the through-hole on the side of the joint body. The contact surface of the nearby oval or elliptical peripheral wall with the outer peripheral surface of the main pipe is brazed and welded, and a part of the peripheral wall at the upper end of the joint body has a rib wall to reduce the diameter of the branch connection port. The branch pipe assembled to the main pipe may be welded to the peripheral wall of the joint by soldering, or the main pipe may be inserted into the joint body, and the peripheral part of the through-hole and the lower end on the side of the joint body. At the same time, solder weld the sealing surface of the peripheral wall at the upper end of the joint body, and solder weld the branch pipe assembled to the branch connection port, which has a ribbed wall on a part of the peripheral wall at the upper end of the joint body and has a reduced diameter, to the peripheral wall of the joint body. and a main pipe with a branch hole in the peripheral wall, and a main pipe inside the through-hole of the joint body, which is a short pipe bored diametrically around the branch hole. The inner circumferential surface of the joint body and the inner circumferential surface of the joint body are inserted while maintaining a gap, and the branch pipe is assembled to the branch connection opening at the upper end of the joint body.In this state, the branch pipe is assembled. A part of the circumferential wall of the branch connection port forming the joint body is press-drawn to have a flat rib wall to reduce the diameter and fit closely to the outer circumferential surface of the branch pipe. The peripheral wall portion where is located is slightly pressed in the opposite direction so that the peripheral wall having an oval or elliptical cross section comes into contact with the outer peripheral surface of the main pipe,
Next, the fitting surface of the peripheral wall of the branch pipe, the hole peripheral part of the through-hole of the main pipe, and the abutting surface of the oval or elliptical peripheral wall of the joint body with the outer peripheral surface of the main pipe are each soldered at once. Welding and forming, or inserting the main pipe into the through hole with a distance maintained between the outer peripheral surface of the main pipe and the inner peripheral surface of the joint body,
The branch pipe is assembled to the branch connection port, and in this state, the branch pipe is assembled by pressing and drawing a part of the peripheral wall of the branch connection port, which forms the part, and shrinking the branch pipe with the rib wall. The diameter is tightened to tightly fit the outer circumferential surface of the branch pipe, and the lower end circumferential wall on the side of the joint body is completely pressed in opposite directions to seal it, and then the fitting surface at the mouth circumferential wall of the branch pipe and the main pipe are After the hole periphery of the through hole and the sealing surface of the lower end peripheral wall of the joint body are collectively soldered and formed, or a main pipe without a diversion hole is inserted into the through hole and the above-mentioned steps are carried out. The gist of this method is to make a branch pipe joint by welding a bracket, then inserting a cutting tool into the interior of the branch pipe to drill and form a branch hole in the peripheral wall of the main pipe.

こととなる。[Function] Because the present invention has such a structure and its manufacturing method, the main pipe is installed in the through-hole of the joint body bored in the peripheral wall, and the branch pipe is installed in the branch connection port at the upper end. Due to the formation and diameter reduction of the flat rib walls associated with the press drawing process, the mutual contact surfaces, the hole periphery of the through hole, the abutment surface by the oval or elliptical peripheral wall, or the sealing surface. By bulk soldering welding, the rib walls produced by pressure drawing provide a reinforcing effect and increase the rigidity of the joint as a whole. Also, the branch pipe assembled at the branch connection port has the same diameter as the main pipe. This makes it possible to connect not only pipes with different diameters, but also pipes of any desired diameter, whether smaller or larger than the main pipe, which alleviates these pipe diameter restrictions and greatly expands the range of applications. This means that it can be expanded to.
