Very Tightness Cemented Carbide Ball Working In Extremely High
Speed
High-precision WC carbide balls are widely used in oil drilling,
deep-sea drilling pumping ball, ball seat, which is also the most
critical component of the pump. Due to the harsh working
environment and conditions in the oil drilling industry, it is
usually contained in sand wells, heavy oil wells and high-pressure
anti-sloping wells with some corrosive substances such as water,
various gases, waxes, sands, etc. The oil is extracted from several
hundred or even thousands of layers, which requires the valve ball
and the valve seat to have good sealing, wear resistance and
corrosion resistance
Our advantages :
1, We offer unground and good finish valve seats for the
application of wear in assembly of gas lift valves, wire line
Retrievable injection operated gas lift valves in oil and gas
industry.
2, Application: To control fluid handling and flow control devices.
3, Standard specifications for valve seats
.
