具有螺旋延伸的扭矩肩部的管状连接件
摘要：
一种管状连接件，包括阳接头构件和阴接头构件。所述阳接头构件具有第一螺纹结构和沿着所述阳接头构件与所述第一螺纹结构轴向间隔开的螺旋扭矩肩部。所述阴接头构件具有第二螺纹结构和沿着所述阴接头构件与所述第二螺纹结构轴向间隔开的第二螺旋扭矩肩部。所述第一螺纹结构和所述第二螺纹结构的大小和位置设置成用于控制管状连接件的入扣位置，在该入扣位置中，所述第一螺旋扭矩肩部不与所述第二螺旋扭矩肩部接合或轴向重叠。还提供了一种利用螺旋扭矩肩部连接管状构件的方法。
摘要（英）：

A tubular connection includes a pin member and a box member. The pin member has a first thread structure and a helical torque shoulder spaced axially along the pin member from the first thread structure. The box member has a second thread structure and a second helical torque shoulder spaced axially along the box member from the second thread structure. The first thread structure and the second thread structure are sized and located to control a stab position of the tubular connection, and in the stab position the first helical torque shoulder does not engage or axially overlap with the second helical torque shoulder. A method of joining tubular members utilizing a helical torque shoulder is also provided.
