Specifications
hollow sucker rod:
1.Standard: API 11B
2.Grade: C,D,K.
3.Type: stereo and hollow pump rod.
Hollow sucker rodhas hole in the middle.
The characters:
1.Chemicals and hot oil can be injected through the inner hole to decrease the viscosity of the oil and the paraffin deposit in the well thus the pump efficiency is increased.
2.The smaller passage and the faster flow velocity can avoid the sand deposit efficiently while use hollow sucker rod in the sand well.
3.Matched with the rodless pump hollow sucker rod can substitute the tubing.
4.Hollow sucker rod can be used to drive the PC pumps as it can bear larger torque.
