Hang-off and/or torque 1 features are provided on the pipes and/or the connections of a high-pressure riser. The hang-off features may be useful to support the weight of the full length of the riser. Accordingly, the hang-off may be done directly in the middle of the connection, where the strength is the greatest. Also, by using the torque features, it is possible to accommodate large torque values. Accordingly, a large torque resistance may be provided while an upper pipe is being made up. A make-up tool taking advantage of the hang-off and/or torque features permits assembling the high-pressure riser more automatically and with less manual intensive labor.
A high-pressure riser, comprising:
A method of assembling a high-pressure riser, comprising:
A make-up tool for assembling a high-pressure riser, the high-pressure riser including at least one coupling having a first end, a second end that is opposite of the first end, and an outer surface, the at least one coupling including a first threaded box located at the first end, a second threaded box located at the second end, and a torque contour located on the outer surface, the high-pressure riser further including at least one collar having an outer surface, the at least one collar including a torque contour located on the outer surface, the make-up tool comprising:
