Abstract
Methods and apparatus are provided for reducing heat transfer to or from a fluid contained within double-walled conduit. A method for reducing the heat transfer from a fluid contained within double-walled conduit includes providing an inner conduit, the inner conduit substantially containing the fluid; providing an outer conduit, the outer conduit substantially surrounding the inner conduit; and connecting the inner conduit to the outer conduit via at least one elongated conduction pathway so as to reduce the heat transfer from the fluid.
Claims22
A method of reducing heat transfer from a fluid in a hydrocarbon production conduit system comprising:
- providing an inner conduit, the inner conduit substantially containing the fluid;
- providing an outer conduit, the outer conduit substantially surrounding the inner conduit;
- and
- connecting the inner conduit to the outer conduit via at least one elongated conduction pathway so as to reduce the heat transfer from the fluid in the hydrocarbon production conduit system, the elongated conduction pathway not including a conduction path traversing a shortest distance between the inner conduit and the outer conduit.
(canceled)
A deepwater hydrocarbon production piping system for reducing heat loss from a contained fluid comprising:
- a pipe segment, the pipe segment comprising an inner pipe;
- an outer pipe, the outer pipe substantially surrounding the inner pipe;
- and at least one elongated conduction pathway connecting the inner pipe to the outer pipe, the elongated conduction pathway not including a conduction path traversing a shortest distance between the inner pipe and the outer pipe;
- and
- a plurality of pipe segments joined longitudinally to form a deepwater hydrocarbon production piping system.
A pipe apparatus comprising:
- an inner pipe;
- an outer pipe, the outer pipe substantially surrounding the inner pipe;
- and
- at least one elongated conduction pathway connecting the inner pipe to the outer pipe, the elongated conduction pathway not including a conduction path traversing a shortest distance between the inner pipe and the outer pipe so as to reduce the heat transfer from a fluid to an external environment.
