Tubing Spool


KINGWELL Tubing Spool Features & Benefits

The tubing spool is the last spool installed before the well is completed. The tubing spool differs from the intermediate spool in one way: it has a profile for accepting a solid body-tubing hanger with a lockdown feature located around the top flange. The lockdown feature ensures that the tubing hanger cannot move because of pressure or temperature. The flange sizes vary in accordance with pressure requirements. When the well is completed, the tree is installed on top of the tubing head with a tubing head adapter.


Tubing Head &tubing spool are a straight bore bowl with 45° landing shoulder design which avoids damage to sealing areas by drilling tools, and provides wedging of the tubing hangers, bowl protectors and test plugs. the secondary seal for the last casing pipe can be an integrated "OO" seal type or the plastic injection type, but also accepts reducer bushings "4-O" and "PE" (Pressure Energized).The upper flange is supplied with lockdown screws for packoff  tubing hanger retention. The lower flange includes a grease fitting and orifice for testing of the secondary seal.
