Abstract
In a flange fastening section that includes a flange of a pipe for forming a connection of the pipe to another pipe by connection of the flange to a flange of the another pipe, the flange has a groove in the face to be connected to the flange of the another pipe for forming the connection. A gasket including expanded graphite is at least partly accommodated in the groove, and at least one O-ring is at least partly accommodated in the groove and at the peripheral surface of the gasket. The O-ring has a cavity through which working fluid may flow, an inlet piping into which the working fluid may flow and an outlet piping out of which the working fluid may flow.
