Abstract:
1. A threaded tubular section, comprising: a first tubular member made of a first material, the first tubular member including a threaded pin section; a second tubular member made of a second material, the second tubular member including a threaded box section configured to mate with the threaded pin section; a pressure equalization device made of a third material and disposed between the first tubular member and the second tubular member, the pressure equalization device including one or more openings configured 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; and components within the pressure equalization device, wherein when the components include a coupler on a first side of the pressure equalization device adjacent to the first tubular member but not on a second side of the pressure equalization device adjacent to the second tubular member, the components are secured to the pressure equalization device to prevent rotation and shearing when the first tubular member is mated to the second tubular member.
