It is a new type sucker rod stem with anti-corrosionanti-friction. It reduces the lowering resistanceneutral pointimproves the force state of rod.
1. Application
It is a new type sucker rod stem with anti-corrosion and anti-friction. It reduces the lowering resistance and neutral point and improves the force state of rod.
2. Main Characteristics
1) High tensile strength
The rod is made of 35CrMo steel of integrated design with sold drawing and polished finish. Its inner has no thread connection. So it promotes the safety factor and improves the tensile strength.
2) Good corrosion resistance
After polish finish, spray-painted anti-corrosion treatment of rod and coupling surface increase the ability of corrosion and friction resistance.
3) Reduce neutral point of eccentric wear
The rod with big diameter of 30mm is applied. It increases 3kg/meter compared with the normal rod so that increase 0.45t each 150m in order to reduce the neutral point of eccentric wear over 100m.
3. Main Tech Parameters
Specification: φ19mm*6.0m
Diameter of the rod: φ30mm
Standard: SY/T5848-1993 SY/T5029-2006
Thread connection: 3/4″ sucker rod thread
Weight: 5.6kg/m
