    Abstract: A fluid cylinder for a reciprocating pump includes a body having inlet, outlet, and plunger bores. The inlet and outlet bores extend coaxially along a fluid passage axis. The plunger bore extends along a plunger bore axis that extends at an angle relative to the fluid passage axis. The body includes a crossbore at the intersection of the fluid passage axis and the plunger bore axis. The crossbore intersects the inlet, outlet, and plunger bores at respective inlet, outlet, and plunger bore ends. The inlet bore end and outlet bore ends are connected to the plunger bore end at respective first and second corners of the crossbore. The first corner includes a first linear bridge segment connected to the inlet and plunger bore ends by corresponding curved segments. The second corner includes a second linear bridge segment connected to the outlet and plunger bore ends by corresponding curved segments.

    Abstract: According to one aspect, data identifying a component is received, wherein the component is part of a system associated with a wellhead. A location at which the component is positioned relative to one or more other components is identified. The useful remaining operational life of the component is predicted based on at least an operational parameter specific to the location, and the operational history of the component or one or more components equivalent thereto. According to another aspect, a model representing at least a portion of a proposed system associated with a wellhead is generated, the model comprising a plurality of objects, each of which has a proposed location and represents an existing component. The useful remaining operational life for each object is predicted based on an operational parameter at the corresponding proposed location, and data associated with the respective operational history of the existing component.

    Abstract: This disclosure provides a valve seat having cladded surfaces of high hardness in order to improve the service life of valve seats. The cladded surfaces may include various materials of favorable mechanical properties for mitigating failure mechanisms known for common valve seats (e.g., having a common base metal throughout). In one example, the cladded surfaces are created using an additive manufacturing process, such as laser metal deposition. The cladded surfaces offer advantages including metallurgical bonding, localized low heat input at the laser focus (thus enabling accurate control of temperature and mitigating undesirable heat treatment effects), ductility in middle layers for increasing impact resistance, variable cladding thickness (optionally exceeding 1 mm), increased hardness by material and fusing temperature selections, corrosion resistance, modification of mechanical properties of the same selected material, and allowing for sensor embedment.

    Abstract: A reciprocating pump assembly includes a fluid end section having a pressure chamber and a plunger bore that fluidly communicates with the pressure chamber. The reciprocating pump assembly includes a plunger configured to be held within the plunger bore of the fluid end section, and a linear actuator operatively connected to the plunger such that the linear actuator is configured to reciprocate the plunger within the plunger bore during operation of the reciprocating pump to thereby pump fluid through the fluid end section.

    Abstract: A fluid cylinder for a fluid end section of a reciprocating pump includes a body having a pressure chamber and a plunger bore that fluidly communicates with the pressure chamber. The plunger bore includes a packing segment configured to hold packing. The fluid cylinder includes a sleeve received within the packing segment of the plunger bore. The sleeve is configured to hold a plunger within an internal passage of the sleeve such that the plunger is configured to reciprocate within the plunger bore during operation of the reciprocating pump. The fluid cylinder includes a retention mechanism secured within the plunger bore such that the retention mechanism is configured to retain the sleeve within the packing segment of the plunger bore.

    Abstract: A bull gear is provided for a reciprocating pump. The bull gear includes a hub extending around an axis of rotation of the bull gear. The bull gear includes a rim having a plurality of helical gear teeth extending along a circumference of the rim. The rim extends a width along the axis of rotation from a first side portion to a second side portion that is opposite the first side portion. The bull gear includes a web connecting the hub to the rim. The web extends a radial length from the first side portion of the rim to the hub.

    Abstract: According to one aspect, a manifold defines an internal region and a first inside surface. A fluid liner is permanently bonded to the first inside surface, and dynamically responds to pressure fluctuations within the internal region during fluid flow therethrough while the permanent bond is maintained. According to another aspect, an end cap is connected to the elongated member and defines a second inside surface. The fluid liner is engaged with each of first and second inside surfaces, and defines a third inside surface. A first thickness of the fluid liner is defined between the first and third inside surfaces, a second thickness of the fluid liner is defined between the second and third inside surfaces, and the second thickness is greater than the first thickness. According to another aspect, a plug opening is formed through the fluid liner, and a liner plug extends within the plug opening.

    Abstract: A hammer union includes a female sub; a male sub; and a wing nut that is concentrically disposed about the female and male subs. The wing nut includes a body having first and second end surfaces, and an exterior surface extending therebetween; a passage extending through the body from the first to second end surface that defines an interior surface of the body; an internal shoulder formed by the interior surface; an internal threaded connection that extends from the first end surface and towards the internal shoulder; and lugs extending radially from the exterior surface. The body has a wall thickness defined between the interior and exterior surfaces, with a greater wall thickness at the internal shoulder than at the first end surface; the internal threaded connection has a full-root radius; and a lug that extends along the axial length of the body.
