A valve comprises a housing including a first chamber, a second chamber, and a neutral chamber. In addition, the valve comprises a stem disposed within the housing. Further, the valve comprises a first valve member at least partially disposed in the first chamber and connected to the stem and a second valve member at least partially disposed in the second chamber and connected to the stem. The first valve member has a closed position seated in a first annular valve seat and an open position spaced apart from the first valve seat. The second valve member has a closed position seated in a second annular valve seat and an open position spaced apart from the second valve seat. Moreover, the valve comprises a biasing member configured to bias the second valve member to the closed position and the first valve member to the open position.

There is provided a system and method for using a thermal insulating paint in a subsea environment. In accordance with one embodiment of the present technique, the thermal insulating paint may be applied to a casing for use in a subsea mineral extraction system. In another embodiment, a surface-rated thermal insulating paint may be applied to any component for use in a subsea mineral extraction system. The insulated component may be protected from the subsea environment to prevent damage to the surface-rated thermal insulating paint. For example, protecting the component may include burying it in cement or concrete, encasing it in another subsea structure or enclosure, or applying a protective sealant over the surface-rated thermal insulating paint.

A fracturing system is provided. In one embodiment, the fracturing system includes a fracturing manifold for routing fracturing fluid to multiple wells. The fracturing manifold can be coupled via fluid conduits to fracturing trees installed at the wells. In some cases, each fracturing tree that is coupled to the fracturing manifold is coupled by at least one rigid fluid conduit. The fracturing manifold can include a trunk line that provides fracturing fluid to multiple outlet branches, which can include valves for controlling flow of fracturing fluid to wells downstream of the valves. Additional systems, devices, and methods are also disclosed.

An ultrasonic transducer apparatus is provided. In one embodiment, the apparatus includes an ultrasonic flow meter (38, 92, 132) having an ultrasonic transducer assembly (50) coupled to a meter body (94, 134). The ultrasonic transducer assembly can include an ultrasonic transducer (112) in a transducer housing (52, 72, 74), and the transducer housing can be positioned within the meter body such that, during flow of a fluid through the meter body, the transducer housing is exposed to, and is in pressure balance with, the fluid. The transducer housing can be positioned in a sheath that acoustically isolates the ultrasonic transducer and its housing from the meter body. Additional systems, devices, and methods are also disclosed.


Patent
