Abstract: Present embodiments of the disclosure are directed to an improved hub clamping system and method used to connect and seal a pair of API hubs. The hub clamping system generally includes a plurality of individually operated clamp units assembled within a single outer retaining ring. The clamp units disposed in the retaining ring may provide a multi-segment clamping arrangement to hold the API hubs together. The clamp units may each include a collet mechanism having a slanted surface shaped to engage one of the pair of hubs, a housing mounted to the outer retaining ring, and a screw device coupled to the collet mechanism via threads and disposed within the housing. The screw device may be rotatable relative to the housing to selectively move the collet mechanism between an activated position and a retracted position relative to the hubs.

Abstract: Modular pumps comprising universal gearboxes and crank units and associated methods.

Abstract: A fluid end manifold comprising a body having a front side and a back side, a first cylinder bore formed horizontally through the body, a second cylinder bore formed vertically through the body, a front mating face, and a back mating face, wherein the first and second cylinder bores intersect within the body to define an intersection region, wherein the front mating face is positioned on the front side of the body at a location corresponding to the intersection region, and wherein the back mating face is positioned on the back side of the body at a location corresponding to the intersection region.

Abstract: A blowout preventer comprising: a main body comprising a seal seating profile, one or more bonnet guideways, and one or more slide guideways; a bonnet attached to the main body, wherein the bonnet comprises one or more guide rods, a ram unit, and a seal seating profile; two retention units attached to the main body and the bonnet, wherein each retention unit comprise a clamp block, one or more guide rods, and a bonnet guideway; and a metal seal, wherein the metal seal is seated in the seal seating profile of the main body and the seal seating profile of the bonnet.

Abstract: A coil tube injector head comprising at least two gearbox units, wherein each gearbox unit drives a gripper assembly comprising a plurality of gripper assembly links. The gripper assembly links comprise a gripper surface that engages a length of coil tubing and one or more roller bearings that engage a bearing plate. The coil tube injector head further comprises a skid plate that is coupled to the bearing plate and receives pressure from one or more traction cylinders. The assembly of the claimed embodiments further allows for ease of maintenance and service of the coil tube injector by operators in the field of oil and gas production.

Abstract: An example drawworks may include an electrical drive motor and an output shaft driven by the electrical drive motor. A worm gear may be coupled to the output shaft and a bull gear may be engaged with the worm gear. A wireline drum may be coupled to the bull gear and receive rotation from the electrical drive motor through the bull gear. The electrical drive motor, worm gear, and bull gear may comprise a drive unit that is removably coupled to the wireline drum. The wireline drum may form a drum unit with at least one spigot coupled to the drum, which may be removable coupled to the drive unit.

Abstract: Couplers for attaching an accessory to an excavator arm of an excavator. Couplers having a first side for attaching the coupler to the excavator arm and a second side onto which the accessory will be coupled. The coupler includes a latch for selectively securing and releasing an attachment pin of the accessory in a jaw, groove, hook or slot in the second side of the coupler. The coupler is fully controllable from within the cab of the excavator and it allows improved security in the securement of the accessory to the coupler, i.e. preventing accidental decouplings, but while still allowing intentional decoupling operations to be carried out without undue burden.
