Pipe apparatus, coupling devices, and methods

A pipe apparatus comprising:

• a first pipe segment comprising a first end portion comprising a first outer circumferential edge;
• a second pipe segment comprising a second end portion comprising a second outer circumferential edge facing the first outer circumferential edge, and the first outer circumferential edge is spaced from the second outer circumferential edge to define a circumferential gap between the first outer circumferential edge and the second outer circumferential edge;
• a seal circumscribing the circumferential gap, the seal comprising a first circumferential flange engaging the first end portion of the first pipe segment and a second circumferential flange engaging the second end portion of the second pipe segment;
• a first circumferential pocket defined between an interior surface of the seal, the first end portion, and the second end portion;
• and
• a fluid guide device positioned at least partially within the first circumferential pocket, the fluid guide device comprising a circumferential guide flange extending at least partially into the circumferential gap between the first outer circumferential edge and the second outer circumferential edge, wherein an axial width of the circumferential guide flange is less than an axial width of the circumferential gap, the circumferential guide flange is spaced from the first outer circumferential edge to define a fluid inlet port, and the circumferential guide flange is spaced from the second outer circumferential edge to define a fluid outlet port, wherein the fluid guide device at least partially defines a fluid path extending from the fluid inlet port through a channel defined between the fluid guide device and the interior surface of the seal, and from the channel to the fluid outlet port,
• wherein the pipe apparatus is configured to pass a quantity of fluid from an interior of the first pipe segment through the fluid inlet port into the channel, through the channel to the fluid outlet port, and through the fluid outlet port to an interior of the second pipe segment.

A coupling device comprising:

• a seal circumscribing a central axis of the coupling device, the seal comprising a first circumferential flange extending toward the central axis and a second circumferential flange extending toward the central axis;
• a first circumferential pocket at least partially defined by an interior surface of the seal, the first circumferential flange, and the second circumferential flange;
• and
• a fluid guide device positioned at least partially within the first circumferential pocket, the fluid guide device comprises a plurality of segments that are radially arranged to circumscribe the central axis, each segment of the plurality of segments comprising an arcuate wall comprising an inner concave surface and an outer convex surface, and each segment at least partially defining a fluid path extending through a channel defined between the outer convex surface and the interior surface of the seal.
