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.
Claims11
A flange fastening section for cooling the flange, comprising:
- 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, wherein the flange of the pipe has a groove in a face of the flange, which face is the face of the flange to be connected to a face of the flange of the another pipe for forming the connection;
- a gasket including expanded graphite at least partly accommodated in the groove;
- and
- a hollow O-ring at least partly accommodated in the groove and arranged on an outer radial peripheral surface of the gasket, wherein
- the hollow of the O-ring is a cavity through which working fluid may flow, the O-ring having an inlet piping into which the working fluid may flow and an outlet piping out of which the working fluid may flow.
