Stellite alloy valve balls and valve seats are critical components of oil well pumps used in oilfields, and their quality directly determines the service life of the pumps. Sucker rod pumps are suspended inside the tubing via support joints, suitable for oil extraction in high-temperature deep wells and deviated wells, with excellent corrosion and high-temperature resistance.
Product Details
Stellite alloy valve balls and valve seats are critical components of oil well pumps used in oilfields, and their quality directly determines the service life of the pumps. Sucker rod pumps are suspended inside the tubing via support joints, suitable for oil extraction in high-temperature deep wells and deviated wells, with excellent corrosion and high-temperature resistance. Stellite alloy valve balls and valve seats are applicable to complex well conditions such as corrosion, slight sand and gas content, and high temperatures, featuring reliable operation and stable performance.
