摘要：
A pliable metallic joint for underwater pipelines laid at great depths, having a bellows-like section of a pliable metal or alloy, which is externally reinforced by a sturdy metal wire coiling positioned in the grooves of said bellows and which is internally reinforced by interlockingly arranged U-shaped rings and an axial undulated circular spring that allow a high degree of deformation and facilitate joining two pipes.
