Rare Earth - High Strength and ultra - long life with anticorrosion Sucker Rod

Product Description

 

1. Advantage: High strength ,Larger torque,high resistance to fatigue and corrosion,long service life.

2. Process:Sucker rod steel containing rare earth elements → Grade D sucker rod Supersonic freqency processing Strengthen shot blasting Electrostatic spraying

3. Key feature

1) Raw material containing rare earth elements

A mixture of rare earth elements lanthanum and certium is added to sucker rod steel , the content of which is 0.05%~0.13% .

The function is grain refinement and microstructure homogenization , so that the comprehensive mechanical properties and anti-corrosion properties are improved , and the overall performance is inform and consistent .

2) Supersonic frequency hardening treatment

After forming, the surface of the whole rod and the coupling are superaudio processed . The depth of the layer is 6%~8% of the diameter, and the structure of the hardened layer is the sub-structure of srrip martensite .

The structure is characterized by high hardeness and good comprehensive mechanical properties, which is an ideal structure that can impove the surface abrasion resistance and strength and toughness.

3) Anti-corrosion coating on the surface

After modification, the use temperature of epoxy resin can be increased to less than 160 degrees celsius.The epoxy resin layer can effectively prevent the contact between oil and the rod body , significantly improving the anti-corrosion performance of the rod.

4) Matters needing attention

If the slope is large, wear to sucker rod and tubing in the well with more serious wear, should use after molded centralizer, can prevent sucker rod eccentric wear ,can avoid tubing to grind again, increased the service life of sucker rod and tubing .

4. Cost performance

The rare earth high strength and long life sucker rod is 1.3 times the price of the D class sucker rod and 0.5 times the price of the AISI4330 material anti-corrosion sucker rod.The service life of the rod is twice as long as that of the D class sucker rod and the material type anticorrosive sucker rod .Due to its high strength , the rod of small size can be used instead of large size ,such a 7/8  rod instead of 1  rod ,which not only saves the purchase cost and pump weight, but also saves the space and increases the oil output.
