Product Description
The PCP application rod is developed by Nine-Ring and patent registered. I t is widely used and recognized in China oil fields. The PCP application rod is replaced for conventional sucker rod and hollow sucker rod suitable for rotary application in progressive cavity pumping.
Most of the progressive cavity pumping is still using conventional sucker rod and ultra high strength sucker rod. These rods are manufactured under API 11B Specifications but defined to work under axial loads for progressive cavity pump. The use of these rods for progressive cavity pumping increase of rod premature failure with higher operating cost.
Nine-Ring designed "Taper Thread" PC rod have higher transmission of torsion and axial load; hence improve the rod fatigue strength that overcomes the weaknesses of using conventional sucker rods. Such designed PC rod helps to improve the reliability of progressive cavity pumping.
Mostly, we provide PC rod and other accessories as one package to our customers, including PC polished rod modified for PC rod purpose, PC pony rod, PC rod itself, coupling, sub-coupling and pony rod with centralizer (Rod Guide). The package is tested, accepted and widely used well in China oilfields.
Nine-Ring PCP rods are available in 7/8 inch (22mm), 1 inch (25mm) and 1-1/8 inch (28mm) body diameter. For the lengths available are 25 feet (7.62m) and 30 feet (9.14m). The PCP rod is using AISI 4130 special alloy steel to manufacture. It is only used for non-corrosive and inhibited oil wells.
Characteristics:
The PC rod thread is designed with large screw pitch (6 threads per inch) and higher thread rigidity, such design allow the PC rod receiving higher make up torque and pre-tightening force;
The PCP rod surface has a thin compression layer at the rod surface that remains under compression even under normal operating tensile loads;
For quality assurance, the PCP rod is using fluorescent magnetic particle and magnetic leakage inspection to check for defect of the rod end and the rod body respectively.
