Abstract
A monolithic isolation stress joint is disclosed having a first conduit element, a first insulating joint assembly, and a stress joint connected to the first conduit element through the first insulating joint assembly. The stress joint is formed of a material which has advantageous elastic flexure characteristics but which is electrochemically active with respect to the first conduit element from which it is electrically isolated by the first insulating joint assembly. A second conduit element is connected to the stress joint through a second insulating joint assembly, the second conduit element being formed of a material which is electrochemically active with respect to the stress joint and which is electrically isolated therefrom with the second insulating joint.
