Abstract
A high pressure flow-through swivel joint is particularly adapted for connecting high pressure water lines to a jet sled in an underwater pipe burying apparatus. The joint includes mating spherical joint surfaces which allow pivotal adjustment during assembly, in order to compensate for construction tolerances. In addition, the mating spherical surfaces allow rotational freedom for the joint inlet passage when the pipe burying system is in operation.
