Pipe apparatus, coupling devices, and methods

Abstract

Pipe apparatus can include a coupling device with a seal circumscribing a central axis. The seal further includes a first circumferential pocket at least partially defined by a first and second circumferential flange. A fluid guide device positioned at least partially within the first circumferential pocket includes a plurality of segments that are radially arranged to circumscribe the central axis. The fluid guide device at least partially defines a fluid path.Methods can include using the coupling device to couple a first end portion of a first pipe segment to a second end portion of a second pipe segment. Methods of using the pipe apparatus can include passing fluid through the fluid path to cool the seal.
