ABSTRACT:
The present invention is directed to slip joint means for use in connecting pairs of axially spaced risers in an off-shore multi-line riser system that conveys petroleum from a collection point on the ocean floor to a floating buoy for delivery to tankers. The slip joint permits considerable latitude in the movement of the riser system yet assuring leak proof joints at the points of movement by providing elastic seals that facilitate motion between conveying conduits.
