Hollow sucker rods form an open passage from the well surface to the bottom of the well that provides several advantages in a variety of production scenarios:
Heavy crude production: Our special skin effect heating system heats up the tubing fluid over the full length of the hollow sucker rods, thus significantly enhancing production of heavy crude. Besides reducing fluid viscosity, paraffin buildup is also minimized.
Chemical injection: Build around an upper hollow rod string connected to an injection unit and a lower solid rod string, our chemical and water injection system reduces fluid viscosity, controls corrosion and scale buildup. Pumping does not need to be interrupted during well washing procedures.
PSP production: Hollow sucker rods resist higher torsion loads (need to verify) than solid rods which make them ideal for use with progressive cavity pumping systems.
The hollow rod connector and coupling are welded to the two ends of seamless steel pipe through friction welding.
Our hollow sucker rods are available in the following diameters:
1.25”, 1.34”, 1.42”, 1.50”, and 1.65” (32 mm , 34 mm, 36 mm, 38 mm, and 42 mm).
