A choke valve includes a choke body, a choke trim disposed in the choke body, where the choke trim is configured to adjust a cross-sectional area of a flow path in the choke body to adjust a fluid flow through the choke valve, a choke plug of the choke trim disposed in the flow path of the fluid flow, a stem of the choke plug that includes a first material, and a tip portion of the choke plug coupled to the stem, where the tip portion includes a superhard material.

Choke plug tip

An underwater assembly includes a flow control device and an actuator coupled to the flow control device, where the actuator is configured to actuate the flow control device. The underwater assembly further includes an insulated housing surrounding the flow control device and the actuator, where the insulated housing is configured to retain heat. The underwater assembly also includes a thermal control system comprising a heat exchanger configured to control a temperature of the actuator.

System for controlling temperature of subsea equipment

A system includes a subsea chemical injection system configured to inject a chemical into a well, wherein the choke trim comprises a first cylinder comprising a first plurality of spiral flow paths, a second cylinder comprising a second plurality of spiral flow paths, wherein the first cylinder is disposed within the second cylinder, and an outer portion comprising a plurality of axial passages, wherein the second cylinder is disposed within the outer portion.

Low shear trim

A system is provided with an ultrasonic flow meter. The ultrasonic flow meter includes a first ultrasonic transducer disposed about a fluid flow path, and a pressure balancing system configured to pressure balance the first ultrasonic transducer relative to a fluid flow along the fluid flow path.

Ultrasonic flowmeter having pressure balancing system for high pressure operation

A system, including an ultrasonic flow meter with a conduit including a conduit wall and configured to flow a fluid, an housing disposed about the conduit to define a fluid chamber about the conduit, wherein the conduit facilitates fluid flow into the fluid chamber and through the ultrasonic flow meter and a first ultrasonic transducer disposed in the fluid chamber.

Pressure balanced ultrasonic flowmeter

A system is provided with a pressure balancing system configured to protect a flow meter. The pressure balancing system includes a housing configured to surround a fluid conduit to define a fluid chamber around the fluid conduit. The fluid chamber is configured to house the flow meter. The pressure balancing system is configured to at least substantially balance fluid pressure internal and external to the fluid conduit via the fluid chamber.
