Abstract
An oilfield assembly including a pump in fluid communication with a string of coiled tubing on a tubing reel through a coiled tubing swivel assembly, includes a fluid inlet segment coupled to a swivel body having a central axis, and a rotatable hollow shaft having a portion that extends axially within the swivel body, wherein the fluid inlet segment, swivel body and hollow rotatable shaft form a conduit for passage of a pumped substance to the tubing reel from the pump. The rotatable shaft includes a first end attachable to the tubing reel, and a distal second end, at least part of which is configured to engage a corresponding indentation in the body, thereby preventing direct contact between the distal end of the shaft and the pumped substance.
