PRESSURE COMPENSATION DEVICE FOR THREAD CONNECTIONS

摘要

A threaded tubular section includes a first tubular member made of a first material, the first tubular member including a threaded pin section. The section also includes a second tubular member made of a second material, the second tubular member including a threaded box section to mate with the threaded pin section. A pressure equalization device made of a third material is disposed between the first tubular member and the second tubular member, the pressure equalization device including one or more openings to equalize pressure in an interior of a thread connection of the first and the second tubular members with pressure in a bore or an annulus of the first and the second tubular members.
