The tungsten carbide seats and balls is the components of gas lift valve for oil well in the oil field. Using gas lift technique is the most economical way in the oil extraction currently.
The gas life technique can’t restrict by the depth of the oil well; injecting the gas to the valve can abate the button’s weight of the oil tube, reduce the pressure, and guarantee the oil extraction continually.
The technique property of the gas lift valve:
a) working temperature: 30℃-120℃
b) The pressure of inlet side of corrugated tube: 8.0-10.0MPa
c) The pressure of outlet side of corrugated tube: 45-50MPa
