PCP hollow sucker rod
PCP hollow sucker rod is used in oil production as component of PCP system.
Application
- Transmission of torque from surface drive to PCP rotor;
- Tubing string washing to remove paraffin and salt deposits and to improve equipment operation efficiency;
- PCP hollow sucker rod can be used as a component of sucker rod string to transmit reciprocal motion from surface drive to sucker rod pump;
Advantages
- PCP hollow sucker rods are made of strengthened heat-treated cold-rolled pipes;
- Hot-upset head ensures equal strength across the sucker rod;
- Tool-joint threads are used for transmission of high torques and ensure reliability and tightness of connections in flexural stress and tensile load;
- String is easy to assemble and disassemble;
- Moulded guides are available;
- Coupling-free connection;
Benefits
- Increased torque transmission;
- Longer runlife of sucker rod string;
- Tubing string can be flushed with drive stopped in order to neutralize effects on formation zone;
- Higher durability of threaded connections;
- Minimum volume of flush agents;
- Reduced time of RIH/POOH operations.;
