n: a device placed in a choke line that regulates the flow through the choke. Flow depends on the size of the opening in the bean;the larger the opening. the greater the flow.

a flow tube for a fixed bean-type choke.

n: a piping arrangement that permits heat from one fluid to be transferred to another fluid as they travel counter currently to one another. In the heat exchanger of an emulsion-treating unit, heat from the outgoing clean oil is transferred to the incoming well fluid, cooling the oil and heating the well fluid. In the heat exchanger of a glycol dehydration unit, heat from the hot lean glycol flows through the inner flow tube in the opposite direction of the cool rich glycol, which flows through a shell built around the tube.

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.

tubes with a diameter slightly larger than the braded wireline or slick line that are used in the “stuffing box” on a wireline intervention to isolate the well pressure and fluid from the atmosphere. They work in combination with oil or wireline grease in
