(n.) - Mechanism used to hang the tubing from within the tubing head by means of a thread.
These load-bearing devices are installed in the top bowl of the tubing head and are run through the BOP. Also doubling as a means to access and manipulate additional smaller tubing lines that are utilized downhole and extended to the surface on the outside of the tubing string(s). Available for any type of single/multiple completion, most FMC tubing hangers accept a BPV that seals the tubing bore. Some hangers are ported for hydraulic control lines, SSSV’s, or other types of completion equipment.
