摘要： Aspects of the disclosure relate to elevator locking system apparatus and methods, and associated components thereof. In one implementation, a slip-type elevator assembly includes an elevator body including one or more slips configured to grip a tubular, and a first door pivotably coupled to the elevator body. The slip-type elevator assembly includes a second door pivotably coupled to the elevator body, the first door and the second door movable between an open position and a closed position. The slip-type elevator assembly also includes a locking system including a bolt movable between an unlocked position and a locked position. In the unlocked position the bolt is disposed in a first cavity formed in the first door. In the locked position a first portion of the bolt is disposed in the first cavity and a second portion of the bolt is disposed outside of the first cavity.

摘要： Aspects of the present disclosure relate to retainer nut locking apparatus and methods for fluid ends, and associated components thereof. In one implementation, a method of operating a fluid end includes installing a retainer nut assembly on a fluid end body by turning a retainer nut in an installation direction and into a bore formed in the fluid end body. The retainer nut has a first surface that faces away from the fluid end body and a second surface that faces that fluid end body. The method also includes rotating a locking tab in a locking direction and into contact with an inner surface of the fluid end body. The locking direction is opposite of the installation direction. The locking tab is disposed inside the bore and adjacent to the second surface of the retainer nut.

摘要： A method of manufacturing a coiled tubing string including uncoiling a flat metal sheet from an accumulator; bending the flat metal sheet that is uncoiled from the accumulator into a tubular form such that the edges of the flat metal sheet form a seam along a longitudinal length of the tubular form; welding the seam formed along the longitudinal length to form a tubing string; and coiling the tubing string onto a spool, wherein the tubing string is heat treated to meet specified material properties in a continuous operation from the accumulator to the spool.
