Hollow sucker rod

Hollow sucker rod

Hollow sucker rod is used as component of dual completion, heating and washing equipment.


  • Transmission of reciprocal motion from surface drive to sucker rod pump plunger;
  • Extraction of produced fluid from pump to wellhead through inner channel;
  • Hollow sucker rod and tubing string washing in order to remove paraffin and salt deposits and to improve equipment operation efficiency;
  • Injection of chemical agents or steam into tubing string or bottom-hole formation zone to reduce effects of complicating factors and to improve oil production;


  • Hollow sucker rods are made of strengthened heat-treated cold-rolled pipes;
  • Hot-upset head ensures equally efficient cross-section of sucker rod and equal inner diameter of channel along entire length;
  • Rolled connection threads ensure high fatigue strength;
  • Thrust cones reduces flexural stress at threads and ensures tight connection;
  • Moulded guides are available;


  • Separate lifting of produced fluid in dual completion & injection equipment sets;
  • Subsurface equipment smaller dimensions due to concentric arrangement of lifts;
  • Decrease metal consumption by using hollow sucker rods without tubing string;
  • Higher fluid velocity reduces deposits of paraffin and salt;
