1. Product Overview
The Choke Manifold (or Fixed Choke Manifold) is connected to the wellhead flowline during oil and gas production well logging operations. By utilizing fixed-size chokes (or orifices), it controls and measures the pressure and temperature of the fluid in the pipeline. This data is then used to calculate the well's oil/gas production rate and capacity, thus completing the logging procedure. This makes the manifold an essential piece of equipment for well logging.
The manifold features flange connections and uses parallel gate valves, making it suitable for prolonged operation in various fluid environments. The manifold is characterized by a long service life and high safety and reliability.
