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.

Pipe apparatus, coupling devices, and methods

The disclosed technology relates to a plastic compound suitable for preparing articles, such as pipe fittings and valves, with good physical properties, such as impact strength, and resistance to environmental stress cracking (ESC). In particular, the technology relates to a vinyl chloride resin, which includes chlorinated polyvinyl chloride ('CPVC') homopolymer. Furthermore, the invention relates to vinyl chloride homopolymer compounds containing the vinyl chloride homopolymer resin, and articles made from such compounds, which compounds meet 23447 cell classifications under ASTM D1784.
