A system for transferring fluid from a pump to a manifold, the manifold having a plurality of fluid inlets. A first pump truck includes a first pump having a first fluid outlet. A first flexible pipe couples the first fluid outlet to a first fluid inlet. The first flexible pipe is self-supporting and forms an arch extending over the first pump truck. The first pump truck may include a second pump having a second fluid outlet and a second flexible pipe may couple the second fluid outlet to a second fluid inlet. A second pump truck may include third and fourth pumps having third and fourth fluid outlets, respectively, that may be coupled to third and fourth fluid inlets by third and fourth self-supporting flexible pipes.

A gate valve includes a valve body having a gate cavity, a bonnet mounted to the valve body over the cavity, a valve stem movably positioned in an axial stem bore in the bonnet, a gate positioned in the cavity and connected to the valve stem, a downwardly directed first stop surface fixed in position relative to the valve stem, and an upwardly directed second stop surface fixed in position relative to the bonnet. In operation, when the gate is moved downward from the open position to the closed position, the first stop surface will engage the second stop surface and thereby prevent the bottom of the gate from contacting the bottom of the gate cavity.

An illustrative modular manifold system includes, among other things, two or more modular pump manifolds, a low-pressure header, and a main high-pressure manifold. Modular pump manifolds may include a low-pressure manifold for supplying fracturing fluid or water to pumps, a high-pressure manifold for supplying fracturing fluid or water to one or more wells and a bleed-off/prime-up manifold. Each modular pump manifold of the modular manifold system is configured to be fluidly isolatable from the other modular pump manifolds. Each isolated modular pump manifold is configured to be flushed with water, bled off and primed up independently of the other modular pump manifolds. After the bleed off, maintenance procedures may be performed on pumps associated with the isolated modular pump manifold. The modular pump manifolds that are not isolated may continue in active fracing stage operations while a modular pump manifold is isolated.

Systems, methods, and devices relating to an additively manufactured multilayered structure. The additively manufactured multilayered structure may be provided by unspooling a material roll of laminate material using a roller system. A welding device may be used to apply welds between layers of the laminate material to distribute a loading between the layers during use.

Devices and methods for reducing vibrations. Methods include inserting a device for reducing vibrations within a pressure-control device, where the pressure-control device includes at least one movable element. The device for reducing vibrations includes a first body comprising a first material inserted adjacent to the at least one movable element and a second body comprising a second material, positioned radially opposite the first body. In one or more embodiments, the method also includes moving the at least one movable element of the pressure-control device and absorbing a portion of vibrations, introduced by moving the at least one movable element, using the device for reducing vibrations.

A system for use in performing fracking operations on a number of well bores includes a first valve assembly positioned at the top of a first well bore. The first valve assembly includes a lower master valve connected to the first well bore, an upper master valve connected to the first well bore above the lower master valve, a first flow cross connected to the first well bore above the upper master valve, a swab valve connected to the first well bore above the first flow cross, and a pumpdown valve connected to the first well bore above the swab valve. The system also includes a pumpdown fluid source and a pumpdown flowline connected between the pumpdown fluid source and the pumpdown valve. In operation of one aspect of the system, fluid from the pumpdown fluid source is conveyed through the pumpdown flowline and the pumpdown valve and into the first well bore.

Systems, methods, and devices for magnetically actuating a gate valve of a subsea system via external magnetic actuation from a magnetic actuator. The magnetic actuator is disposed externally around a valve cavity such that motion of a valve stem disposed within the valve cavity can be controlled externally through magnetic coupling with the magnetic actuator such that a physical link (and the dynamic pressure seals associated therewith) is not needed to actuate the valve stem.

A disclosed choke valve insert includes a cage, bonnet, valve stem, and seal assembly. The cage has an orifice configured to receive a flow of fluid. The bonnet is disposed superior to the cage and has a stem bore and cavity. The seal assembly is disposed within the cavity and around the stem bore. The seal assembly includes a seal housing, inner seal, and outer seal. The seal housing has an inner slot and outer slot. The inner seal is disposed within the inner slot and configured to prevent a portion of the flow of fluid from leaking superiorly past the inner seal. The outer seal is disposed within the outer slot and configured to allow the portion of the flow of fluid to return to the stem bore inferior to the inner seal when the inner seal fails.

Systems, methods, and devices for providing a joining technique for a metal part and a composite part. The joining technique in which either the metal or the composite part has at least one portion receive a laser etching treatment according at least in part to a laser configuration. Further, the joining technique in which the metal and composite parts are positioned to contact at least one etched surface. Even further, the joining technique in which a joining process is used to join the metal part and composite part to produce a unitary structure.
