Abstract: A sacrificial body mitigates cavitation damage to components within a pump. The sacrificial body is mounted in the pump so that flowing fluid passes over the sacrificial body, which causes the sacrificial body to shed electrons into the flowing fluid in the vicinity of the cavitation. The excess electrons tend to suppress hydrogen ions from releasing, which can mitigate cavitation. The sacrificial body is formed of a material having less resistance to corrosion due to the flowing fluid than the components of the pump. Needles are attached to the sacrificial body for immersion in the flowing fluid to facilitate the release of the electrons for the sacrificial body.

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.
