According to the present invention, a pipe connecting device to combine a synthetic resin pipe and a metal pipe composition includes a synthetic resin connector, a metal connector, a gasket, a compression flange, and a fixing device. The synthetic resin connector has a first connecting pipe, a first flange part which is placed in the end of the first connecting pipe and has a diameter bigger than that of the first connecting pipe, and a first connecting flow path which is prepared to pass through the middle of the first connecting pipe and the first flange part. The metal connector has a second connecting pipe, a second flange part which is placed in the end of the second connecting pipe and has a diameter bigger than that of the second connecting pipe, and a second connecting flow path which is prepared to pass through the middle of the second connecting pipe and the second flange part. The gasket is placed between the first flange part of the synthetic resin connector and the second flange part of the metal connector, and the compression flange is coupled to the synthetic resin connector to be adhered to an opposite side of surface facing the gasket of the first flange part. The fixing device has multiple fixing bolts and nuts which are to apply welding force to the second flange of the metal connector and the compression flange for the two to approach each other. |
