Sucker rod blowout preventers are necessary equipment to prevent blowout accidents and ensure safe, fast, and excellent workover operations, as well as to achieve negative pressure workover operations
Mainly used in artificial lifting oil production systems to effectively control the internal pressure of the wellbore and prevent blowout.
The sucker rod blowout preventer equipped with special rams can clamp the pipe string, seal the annular space between the pipe string and the wellhead, and also withstand the weight and rotational torque of the downhole pipe string.
