Ultra Hi-Strength Sucker Rod, HY TypeThe HY Type Ultra Hi-Strength Sucker Rod is made from low-carbon alloy steel. The HY Type Ultra Hi-Strength Sucker Rod has a high tensile strength, its bearing capacity is better than D-grade rod. The rod has hardened surface, so it is better than D-grade rod in terms of corrosion resistance and abrasion resistance.
Hollow Sucker RodHollow sucker rods can be used to added diluents, corrosion inhibitors, hot oil to the wells to reduce the viscosity of crude oil and control paraffin buildup in the well, which will help improve the physical property of the well bore and the efficiency of the pump. The hollow rod is also suitable for sandy oil wells. Due to the fact that the torsion strength of the hollow rod is bigger than that of ordinary rod, it can be used to drive downhole screw pumping unit.
