Abstract

A subsea well apparatus having an improved means of axially connecting the plurality of tubing string sections disposed about each riser conduit section. The subsea well apparatus has a riser conduit section with a mating flange at each end, tubing string receiving orifices disposed about the mating flanges, and a tubing string section with its ends disposed within an orifice in each mating flange. Further, the end portions of the tubing string section are shaped for free axial movement within each orifice and there is provided a means for axially adjusting the position of each tubing string end portion in order to selectively adjust the position of each tubing string end surface relative to the end surface of the adjacent mating flange. The end portions of the tubing string sections may be provided with an outwardly-extending radial flange, and the axial adjusting means may be an annular ring circumventing the tubing string section and movably-attached to the riser mating flange by threaded engagement.
