n: a tool with three consistently larger spools that are used to enlarge tubing diameter gradually. The tubing broach may be used either to enlarge the diameter of obstructed tubing or to cut paraffin or other substances that may be inside the tubing.

n: It prevent damaging the oil tube when detaching it through bracketing in the casing.

n: a special connector used to connect lengths of tubing.

n pi: a clamping apparatus used to pull tubing. The elevators latch onto the pipe just below the top collar. The elevators are attached to the hook by steel links or bails.

n: a tool containing a spring-loaded finger, or dog, that pops out when the tool reaches the bottom end of the tubing string. The extended dog prevents the tool from being raised back into the tubing, thus indicating to an operator on the surface that the bottom of the tubing has been reached. The tool is removed from the tubing by jarring upward with enough force to shear a brass pin and allow the dog to rotate downward and into a slot in the body of the tubing end locator.

a wireline device that indicates when the end of tubing is reached.

n: a tool designed to cut away scale, calcium, small deposits of paraffin, and other debris in an obstructed length of tubing. The tool is also used to measure, or gauge, the internal diameter of tubing.

n: an arrangement of slips and packing rings used to suspend tubing from a tubing head.

n: A device attached to the topmost tubing joint in the wellhead to support the tubing string. The tubing hanger typically is located in the tubing head, with both components incorporating a sealing system to ensure that the tubing conduit and annulus are hy

a slip set or donut that suspends and holds the top of the tubing in the wellhead.

n: a flanged fitting that supports the tubing string, seals off pressure between the casing and the outside of the tubing, and provides a connection that supports the Christmas tree.

n: A wellhead component that supports the tubing hanger and provides a means of attaching the Christmas tree to the wellhead.

a flanged spool containing the tubing bowl where the tubing hanger will set and seal.
