要旨とするものである。[Detailed Description of the Invention] Kiichimei relates to a new method for joining metal pipes such as stainless steel pipes for piping, and includes a diameter expansion tool exclusively for the female side that enlarges the diameter of one end to be joined together. Inflate the female side with an abutting edge on the inner end and a rolled-up edge on the outer end, and similarly expand the other end with a male-specific expansion tool to expand the diameter. The female enlarged part is provided with a stepped engagement edge, and after applying adhesive to the inner surface of the male enlarged part or the outer surface of the male enlarged part, the female enlarged part is inserted into the female enlarged part. The tip of the male side swelling part is brought into contact with two sets of abutting edges (two sets), and the rolling edge is contracted using a diameter reducing tool exclusively for rolling in, which reduces the diameter of the rolling edge, thereby making the rolling edge into a step. The object is to engage the shaped engagement edge and at the same time bring the inner surface of the female enlarged portion into close contact with the outer surface of the male enlarged portion.

合もある。In addition, instead of the core α9 and the truncated cone-shaped protrusion (5), an expansion worker using internal pressure such as hydraulic pressure may be used to perform the expansion. It is commercially available with a large part and a male enlarged part on both ends of joints such as elbow cheeses, sockets, reducers, U-shaped vents, etc., and the user can install it on-site using a dedicated diameter reduction tool (/9 only). There is also.

である等の実用的効果を奏するものである。Since the present invention is as described above, the pressure of the fluid flowing through the piping acts to expand the male side expansion part outward, thereby increasing the adhesion. It has the favorable advantage of being a groove structure that does not cause strain on the pipes during joint construction, and is also economically superior as it does not require joint parts such as seals.In addition, as mentioned above, it reduces internal pressure. The higher the value, the better the adhesion (of course, there is a limit), so it has practical effects, such as being effective when used for piping for several buildings in high-rise buildings.
