A stage tool assembly comprises a stage tool and a control line protector. The stage tool comprises a plurality of port holes disposed through an outer surface of a body, and a plurality of securing pin holes disposed on the outer surface of the body. The control line protector comprises a first collar, a second collar, and a rib coupled to the first collar and the second collar. The stage tool assembly also comprises a plurality of control lines that are configured to supply power to one or more sensors disposed on the outer surface of the body, and the control lines are disposed between the rib and the outer surface of the body. The stage tool assembly also comprises a plurality of securing pin members disposed in the plurality of securing pin holes to prevent the control line protector from moving relative to the body.

A segmented fluid end module comprises a first, second, and third body each comprising a bore formed therethrough. The first body is coupled to an upper end of the second body by a first plurality of fasteners that extend through the first body. The bore of the first body is in fluid communication with the bore of the second body. The third body is coupled to a side of the second body by a second plurality of fasteners that extend through the third body. The bore of the third body is in fluid communication with the bore of the second body. A pump system comprises the segmented fluid end module, a suction manifold coupled to the first body, a discharge manifold coupled to the third body, and a power end comprising a plunger that extends into the second body.

An insert for a slip in a hydraulic spider, including an engagement body. The engagement body including an engagement surface. The engagement surface including a first concave surface portion and a second concave surface portion. The first concave surface portion including teeth with a first radius of curvature. The second concave surface portion including teeth with a second radius of curvature that is different than the first radius of curvature.

Aspects of the disclosure relate to counterbalance systems for catwalk systems, and related methods. A counterbalance system pulls a trough of a catwalk system while actuating the catwalk system. A catwalk system includes a chassis, a main arm pivotably coupled to the chassis, a trough pivotably coupled to the chassis and having one or more rollers, a V-door ramp pivotably coupled to the chassis, and a counterbalance system coupled to the trough at a coupling point. The counterbalance system includes a first sheave suspended from the V-door ramp, a second sheave suspended from the first sheave, and a counterbalance rope wound at least partially about the first sheave and the second sheave. A first end of the counterbalance rope is coupled to the trough at the coupling point.

Aspects of the present disclosure relate to locking assembly apparatus for piston apparatus and pony rod apparatus of pump systems (such as mud or frac pump systems), and related methods. In one aspect, the locking assembly is a mechanical locking assembly used to quickly and simply lock and unlock (e.g., release) a piston apparatus to and from a pony rod apparatus.

A pump includes a power end and a fluid end coupled to the power end. The power end includes a plunger, and the fluid end includes a crossbore in selective fluid communication with inlet and outlet bores. A suction valve controls fluid communication between the inlet bore and the crossbore, and a discharge valve controls fluid communication between the outlet bore and the crossbore. An actuation device is used to move the discharge valve between an open position and a closed position. A position sensor measures a position of the plunger. A pressure sensor measures a pressure of the crossbore, the inlet bore, or the outlet bore. A controller operates the discharge valve based on data from at least one of the position sensor or the pressure sensor.

A stage tool assembly comprises a stage tool and a control line protector. The stage tool comprises a plurality of port holes disposed through an outer surface of a body, and a plurality of securing pin holes disposed on the outer surface of the body. The control line protector comprises a first collar, a second collar, and a rib coupled to the first collar and the second collar. The stage tool assembly also comprises a plurality of control lines that are configured to supply power to one or more sensors disposed on the outer surface of the body, and the control lines are disposed between the rib and the outer surface of the body. The stage tool assembly also comprises a plurality of securing pin members disposed in the plurality of securing pin holes to prevent the control line protector from moving relative to the body.

A tubular centralizer including a housing, a guide plate, and a pin. The housing has a plurality of adjustment pin holes. The guide plate is at least partially disposed within the housing and movable between a retracted position and an extended position. The guide plate includes a plurality of adjustment pin slots. The pin is positioned in a first adjustment pin hole of the plurality of adjustment pin holes, and in a first adjustment pin slot of the guide plate. A length of the first adjustment pin slot within which the pin is positioned sets a limit of the extended position and the retracted position of the guide plate.

A pump includes a power end and a fluid end coupled to the power end. The power end includes a plunger, and the fluid end includes a crossbore in selective fluid communication with inlet and outlet bores. A suction valve controls fluid communication between the inlet bore and the crossbore, and a discharge valve controls fluid communication between the outlet bore and the crossbore. An actuation device is used to move the discharge valve between an open position and a closed position. A position sensor measures a position of the plunger. A pressure sensor measures a pressure of the crossbore, the inlet bore, or the outlet bore. A controller operates the discharge valve based on data from at least one of the position sensor or the pressure sensor.

A check valve having a valve body, a valve cover, and a flapper valve assembly. The valve body comprises a valve housing and a central bore formed through the valve housing. The central bore has at least a first bore section, a second bore section, and a third bore section. A transition from the second bore section to the third bore section is radiused such that the inner surface of the central bore at the transition is a continuous surface. The flapper assembly is disposed in the central bore of the valve body and comprises a flapper, a valve seat, and a hinge.
