Abstract: A multi-passage ball joint assembly for connecting a riser or similar pipe to a well pipe therebelow and adapted primarily for use in underwater installations. The ball member of the joint assembly has a main longitudinal bore or passage through which well operations may be conducted and additionally is formed with at least one other passage for conducting fluid therethrough. The housing of the joint assembly includes passageways which are in communication with the bore and passages extending through the ball member in all positions of said ball member relative to the housing whereby fluid may be conducted downwardly through the ball joint for actuating devices therebelow or for other purposes. This abstract is neither intended to define the invention of the application which, of course, is measured by the claims, nor is it intended to be limiting as to the scope of the invention in any way.
