ABSTRACT:
A pipe swivel joint for simultaneous transfer of a plurality of separated fluids between a plurality of inlet conduits and a plurality of corresponding outlet conduits. The swivel joint includes an annular inner element, an annular outer element surrounding at least a part of the inner element, and a plurality of annular fluid flow passages formed between the outer surface of the inner element and the inner surface of the outer element. Each of the inlet conduits is connected to the portion of a corresponding one of the flow passages that is defined by the outer surface of the inner element, and each of the outlet conduits is connected to the portion of a corresponding one of the flow passages that is defined by the inner surface of the outer element. The cross-sectional configuration of each of the fluid flow passages is preferably circular in order to allow passage of spherical or round cleaning elements through them, and an annular bearing race chamber, defined by the outer surface of the inner element and the inner surface of the outer element, contains a plurality of ball bearings to facilitate rotational movement of the outer element relative to the inner element.
