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. |

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; and 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.
