A choke for a flow line having an inner diameter has a body with an upstream end, a downstream end, and a sidewall that extends between the upstream end and the downstream end. The sidewall has a diameter that is sized to fit within the inner diameter of the flow line. A fluid impact face is provided at the upstream end of the body. The fluid impact face has a recessed central portion. One or more passages provide fluid communication between the downstream end and the sidewall of the body. |
