A cylindrical-shaped core drum typically fabricated from steel and bounded by parallel flanges mounted transverse to the core for use in storing and transporting coiled tubing. The service reel is generally equipped with a self-contained hydraulic drive system to control rotation of the reel, an onboard hydraulic levelwind apparatus, and onboard high-pressure piping which connects to the coiled tubing through a high-pressure rotating swivel. The diameters of the cylindrical core and boundary flanges will vary relative to the tube diameter and length to be spooled onto the reel.
