Abstract
A method to manufacture a tubular connection includes calculating an engaged thread area of one of a pin member and a box member of a proposed wedge-thread connection, multiplying the calculated engaged thread area by a dope thickness factor to obtain a target free volume for the proposed wedge-threaded connection, and constructing the manufactured wedge-threaded connection having a total clearance gap volume substantially equal to the target free volume.
Claims21
A method to manufacture a tubular connection, the method comprising:
- calculating an engaged thread area of one of a pin member and a box member of a proposed wedge-threaded connection;
- multiplying the calculated engaged thread area by a dope thickness factor to obtain a target free volume for the proposed wedge-threaded connection;
- and
- constructing a manufactured wedge-threaded connection having a total clearance gap volume substantially equal to the target free volume.
1 more element
A wedge-threaded tubular connection, comprising:
- a pin member and a box member, wherein each of the pin and box members include an engaged thread area;
- a total clearance gap volume of the pin and box members, wherein the total clearance gap volume is calculated by multiplying the engaged thread area of one of the pin member and the box member by a dope thickness factor.
