Abstract

An improved tubular system for transporting a fluid at high temperature and high pressure is described wherein the improved tubular system includes a first rigid tubular segment having an axial bore including a male connector end fitting portion terminating at a proximal end thereof, the male connector end fitting portion comprising a radial shoulder surface having an outer circumferential rim, the radial shoulder surface being perpendicular to the longitudinal axis of the first rigid tubular segment, the male connector end fitting portion further comprises an end fitting body section exhibiting a frusto conical configuration slpingly extending a specified length from the circumferential rim toward the proximal end of the tubular segment; a seal member fixed on a tubular surface of the first tubular member at the terminus of the end fitting body section, with the proviso that the seal member is fixed on the tubular surface in the absence of a groove in the first tubular surface; and a second rigid tubular segment having an axial bore for transporting fluid at high temperature and high pressure, the second rigid tubular segment including a female connector end fitting portion terminating at a proximal end thereof, the female connector end fitting portion comprising an opening defining an inner cavity, the inner cavity exhibiting a tapered.
