摘要： A tubing hanger assembly includes a body having an annular outer surface, a lockdown feature which is located on the body, a load nut which is threadedly connected to the body and has a downward facing load shoulder, and a piston assembly for adjusting a vertical distance between the load shoulder and the lockdown feature. The piston assembly includes an elongated cylinder which is positioned circumferentially around the body axially adjacent the load nut. The cylinder has a first cylinder end which is connected to the body and an open second cylinder end. An elongated piston is slidably received in the cylinder. The piston has a first piston end which is oriented toward the first cylinder end and a second piston end which is configured to extend through the second cylinder end and engage the load nut such that extension of the piston causes the load nut to rotate relative to the body. A seal is positioned between the piston and the cylinder to thereby define a piston chamber between the first cylinder end and the first piston end which is connectable to a source of fluid pressure. In operation of the piston assembly, the piston rotates the load nut to thereby move the load nut axially relative to the body so that the axial distance between the load shoulder and the lockdown feature can be adjusted.
