a three-way connection. In a wellhead, a flow cross connects the master valve and the swab valve with the wing valve.

n: a single unit that acts as an oil and gas separator, an oil heater, and an oil- and water-treating vessel. See heatertreater.

n: a restriction installed in a line of flowing fluid that produces relatively high differential pressures with relatively low permanent pressure losses as the fluid flows through the device. By measuring the differential, the volume of fluid flowing through the tube can be inferred.

n: a device that controls product flow and directs it to the proper location. Mainline valves and side taps are examples of flow-control connections.

n: a place in the flow line from a well, heater-treater, or other device where valves, meters, inlets, outlets, and various gauges may be installed.

n: a cylindrical vessel into which an emulsion is piped to be broken down into its components. See electrostatic treater;heater-treater.

n: the process of separating, or breaking down, an emulsion into oil and water in a vessel or tank on a continuous basis (i.e., without an interruption in the flow of emulsion into the tank or vessel). Compare batch treating.

n: the receding board installed on the bottom surface of upper sieve on the serial vibrosieve
