Abstract
The present invention provides a pipe structure including a pipe that is disposed along an approximately horizontal direction, and has a plurality of ducts through which a gaseous body having a higher temperature than a temperature of a surrounding atmosphere continuously flows, and a plurality of couplings each connecting the ducts together; and a cover covering an outer periphery of the pipe. The cover defines a plurality of vents from which the gaseous body leaking from the pipe flows out of the cover at an interval in a length direction of the pipe. As the plurality of vents, the cover includes at least first vents located corresponding to the couplings. Respective positions of the first vents are substantially set within a range from a two o'clock position to a ten o'clock position through a six o'clock position in a cross sectional surface of the cover.
