The TIW® IB-DD Hydro Hanger is an “Integral Barrel Drill Down” design, providing the operator the ability to rotate and/or reciprocate the liner to bottom without fear of premature setting of the hanger slips. Available in both single and tandem cone versions, the single cone design allows for maximum bypass for circulating while maintaining the ability to hang short to medium length liners. The tandem cone design allows for even greater bypass areas and is capable of hanging medium to long liners.
