  • Interchangeable choke assembly
    Patent number: 6892818
    Abstract: A pressure reducing apparatus and a method of operating a pressure reducing apparatus are provided. The apparatus is operable to reduce the pressure and flow rate of oil being discharged from a well head to downstream processing equipment. The device has central flow channel configured to receive a flow of oil and reduce the pressure in the oil. The apparatus has internal components formed of a ceramic material that resists erosion and wear caused by sand and other debris in the oil. In one embodiment of the invention, a ceramic outer sleeve is disposed in the central flow channel and cooperates with a ceramic inner sleeve having an orifice. The ceramic inner sleeve is interchangeable with other ceramic sleeves having different orifices to modify the pressure and flow characteristics of oil as it is discharged to the downstream processing equipment.
    Type: Grant
