Abstract
A joint for connecting pipe sections is provided in which a portion of the joint includes a first pipe section, a first reducer fitting section, a first flange attached to the first pipe section and having holes for receiving fasteners, and a fluid conduit (such as a pipe sleeve) positioned inside at least a portion of the first pipe section and the first reducer fitting, wherein the fluid conduit forms an annular space defined by the outside surface of the fluid conduit wall and the inner walls of the first pipe section and the first reducer fitting. The annular space separates the heat-sensitive flange, a flange gasket, and the flange fasteners from high-temperature fluids flowing in the fluid conduit, thereby allowing for the use of lower rated and less expensive components than would otherwise be required in a direct heat contacting arrangement.
