PCP hollow polished rod is used for oil production as component of PCP system.
Application
- Wellhead sealing;
- Transmission of torque from a surface drive to PCP rotor;
- Hollow sucker rod and tubing string washing in order to remove paraffin and salt deposits and to improve efficiency of system;
- Can be used for reciprocal motion from surface drive to plunger of sucker rod pump;
Advantages
- Hot-upset rod head ensures equal strength across polished rod;
- Tool-joint threads are used for transmission of high torques and ensure reliability and tightness of connections at bending stress and tensile loading;
Benefits
- Tubing string can be flushed with idle drive without affecting formation zone;
