Abstract
An improved high-pressure swivel joint, which can be used to connect two conduits rotatably. The swivel joint includes an inner conduit and an outer conduit, which are secured together by means of linear roller bearings. Elastomeric packing is provided to prevent the fluid from entering the bearings. The unique design of the swivel joint allows it to be safely used in high pressure and high velocity fluid transfers and also for sour gas services.
