An apparatus for applying torque about an operational axis of rotation includes a first torque device member. In addition, the apparatus includes an actuator support configured to move radially relative the operational axis and configured to be restricted from rotating in a plane oriented perpendicular to the operational axis. Further, the apparatus includes a first torque actuator pivotally coupled to the first torque device member and the actuator support. Still further, the apparatus includes a rod or a second torque actuator pivotally coupled to the first torque device member and the actuator support. Moreover, the apparatus includes a second torque device member coupled to the first torque device member and disposed about the operational axis of rotation. The actuator support is pivotally coupled to the second torque device member and is configured to pivot about a first pivot axis towards and away from the operational axis of rotation.

A floor wrench for a drilling rig floor is provided. The wrench can include a tong assembly having upper and lower tongs made up of articulated tong blocks that can move and lock together to enclose and make or break a joint between sections of drilling pipe. Each tong block can include a pair of die ram assemblies wherein each tong can have dies to grip the drilling pipe around its circumference. The tong assembly can be mounted in a frame configured for horizontal and vertical movement to and from the pipe joint. In some embodiments, the wrench can further include a pipe spinner having motorized spinners that can spin the upper pipe to form the joint prior to torqueing the joint together, or for uncoupling the upper pipe after the joint is broken.

Systems, apparatus and methods are described where a heater is arranged adjacent to a pipe make/break vise assembly to heat a female tool joint of two pipe sections connected by threads to facilitate breaking or disconnection of the joint. The heater can have any configuration or can be used in any manner to result in even heating around the circumference of the female tool joint. In addition, the heater can be incorporated into the same apparatus as the make/break vise assembly, or the heater can be an apparatus that is separate from the apparatus containing the make/break vise assembly. In one embodiment, the heater can be used as a stand-alone heater to heat the female tool joint.

A downhole pump is used for a reciprocating pump system having a rod string disposed in a tubing string. A barrel of the pump is disposed, and a plunger of the pump coupled to the rod string is movably disposed in the barrel. The plunger has an external surface disposed at an annular gap relative to the barrel's internal surface. The external surface has circumferential grooves defined thereabout that hold wipers. An inner ring of the wipers composed of a swellable material is engaged in the one or more circumferential grooves, while an outer ring composed of a second material is disposed about the inner ring. The swellable material of the inner ring energizes the outer ring in slideable engagement with the internal surface of the barrel.

A uniquely designed torque wrench having a torque body, the torque body attached to a frictional squeezing clamp, and a lug socket which is rotationally connected to the frictional squeezing clamp. The frictional squeezing clamp entering a contracted stated during extension of a rod of a hydraulic cylinder, and entering an expanded state during the retraction of the rod of a hydraulic cylinder, the lug socket turning the wing nut of a hammer union.

A quick release die block system for the gripper of a backup wrench is disclosed. The quick release die block system can include a die block releasably coupled to a die block support. A lock mechanism can include one or more lock pins moveably supported and can be operable with the die block and the die block support, The lock mechanism can also include a lock mechanism interface accessible via a passage in the die block, and can be adapted to releasably secure the die block to the die block support.

A locking mechanism for locking a mast includes a double acting cylinder having a piston coupled with a piston rod adapted to slide inside a cylinder barrel. The cylinder barrel is coupled with a first shaft through a first coupling pin. Mounting brackets coupled to a base plate of the mast guide a sliding motion of the first coupling pin, and the cylinder barrel. A first locking pin connected to the piston rod selectively engages a first side plate based on the sliding motion of the piston rod. A retraction stopper restricts a sliding motion of the first locking pin away from the first side plate, and subsequently causes a movement of the cylinder barrel towards the first end of the cylinder barrel. A second locking pin connected to the shaft selectively engages a second side plate based on the sliding motion of the cylinder barrel.

A tong includes a frame having jaws configured to engage a tubular and a tong control assembly disposed on the frame. The tong control assembly includes a housing connected to the frame, a shutoff switch, and a toggle lever located at a suitable position on the housing, whereby the toggle lever is configured to be operated while the shutoff switch is depressed, and wherein the toggle lever is configured to control at least one of: a rotational speed of the jaws and a rotational direction of the jaws. A method of operating a tong includes clamping a first tubular using first jaws of a tong, clamping a second tubular using second jaws of the tong, rotating the first tubular relative to the second tubular, and controlling a rotational speed of the first tubular using a toggle lever disposed on a frame of the tong.

A device and method for installing a pipe into a rotating control device (RCD) head and for removing a pipe out from a RCD head are described. The device includes a body section for receiving and securing a RCD head placed thereon; and a scoping section configured to secure a first end of the pipe, and to push the first end of the pipe into a bore of the RCD head or to pull the first end of the pipe out from bore of the RCD head. The body section is configured to be substantially stationary when the scoping section pushes the first end of the pipe into the bore of the RCD head, or when the scoping section pulls the first end of the pipe out from the bore of the RCD head.
