Further, the auxiliary flange has a lower surface formed with a coupling groove to which the rubber ring is coupled.

Further, the coupling flange is formed with a plurality of connection holes into which the bolts are inserted.

The coupling flange is formed at its rear surface with an engagement groove at a depth corresponding to the height of the vane outside the center hole.

Further, the rear surface of the coupling flange and the rear surface of the stub are arranged so as to form a smooth surface in which neither of them protrudes.

In addition, the material of the stub and the coupling flange may be made of plastic or metal.

According to the pipe connecting apparatus according to the embodiment of the present invention,

First, since the rear face of the coupling flange and the rear face of the stub are combined so as to form a single face, they can be tightly coupled with each other at the time of coupling of the pair of coupling flanges, .

Second, since a pair of coupling flanges are tightly coupled, it is possible to improve the bolt torque reference in bolt and nut coupling.

Third, the rubber ring is provided on the rear surface of the stub, so that leakage of water can be prevented in the coupling between the pair of pipe connecting devices.

Fourthly, a locking groove is formed on the rear surface of the coupling flange, thereby preventing the auxiliary flange of the stub from protruding outward from the rear surface when the coupling flange and the stub are engaged, so that the rear surface of the coupling flange and the rear surface of the stud can be coupled have.

Fifth, since the material of the stub and the coupling flange can be made of plastic or metal, it can be suitably applied to a material suitable for the application.

Referring to Figs. 6 to 10, the pipe connecting apparatuses 100 are constituted as a pair, and are joined by a bolt B and a nut (N) coupling.

The pipe connection device 100 includes a stub 110 and a coupling flange 120.

The stub 110 is provided in a cylindrical shape having a communication hole 111 communicating with the pipe and includes a tubular body 112, an auxiliary flange 113 and a rubber ring 114.

The stub 110 may be welded to the end of the pipe to communicate with the pipe, or may serve as a pipe by itself.

The auxiliary flange 113 protrudes outward along one side edge of the body 112 and the rubber ring 114 is joined to the back side of the auxiliary flange 113 to prevent leakage.

Therefore, it is possible to prevent the leakage of the joint portion between the pair of pipe connecting devices 100 by the rubber ring 114.
