摘要

2072103 9204526 PCTABS00011 The tubing hanger seal assembly of the present invention includes a metal to metal seal that is energized by a drive sleeve. The drive sleeve is threaded to the outside of the tubing hanger and as it is rotated downward, engages a load ring which in turn energizes the metal to metal seal by compressing it between a shoulder on the outside of the tubing hanger and the inside of the tubing head. In addition, the invention includes a split ring which is forced into a groove in the inside of the tubing head to prevent the seal from being blown-out by upward pressure.
