New product introduction of sucker rod

1.Extra-high strength and ultra-long life sucker rod

Our company has developed an ultra-high strength sucker rod, tensile strength reaches 1195Mpa ~ 1400MPa. Torque of 1 inch sucker rod is tested to reach 2800N.M, and fatigue strength reaches 2.05 million timesunder 540MPa load.

Advantages:

a. Saving materials

The smaller size can take the place of lager one.For example: 7/8 “sucker rod can replace 1” sucker rod, and so on.

b. Ultra-long life

The service life of this type is 1.5to 2 times longer than D-grade sucker rod.

c.Low cost

The price is just 1.1 to 1.2 times higher than D-grade. The cost of oil production is greatly reduced.

This new type of sucker rod is applying for a patent for now.

2.Rare Earth High Strength Sucker Rod

This Sucker Rod is the application of the “ultra-high strength steel rod” (Patent No. IL201010279571.5),adding an appropriate amount in the normal sucker rod material smelting of rare earth elements, like the cerium, lanthanum, greatly improves the performance of sucker rod, after heat treatment, metallographic structure has been refined to improve the mechanical performance, fatigue strength and service life. After years of using contrast, life can be increased more than 1.5 times, it has been widely recognized at home and abroad users.

3.Supersonic Frequency Heat Treatment of High Strength Sucker Rod

With 23 KHE Supersonic Frequency heating equipment of finished product surface quenching, quenching layer depth is 5% -13% of rod body diameter , the best layer depth is between 7%- 9% of rod body diameter, surface hardness is HRC50-56. The processed surface get banded structure can increase strength, at the same time, the surface of rod body may obtain 500 Mpa/C㎡ compressive stress. This compressive stressstate can effectively improve the fatigue strength, increase the service life, and improve the service life of 1.4 to 1.6 times.

4.Supersonic Frequency Torsional Plug Type Sucker Rod.

Application of supersonic frequency surface quenching technology for processing the Torsional Plug Type Sucker Rod, Because the surface of the reinforcement effect for screw pump, provides more torque, integrated surface compressive stress state effectively improved the fatigue strength, greatly improving the service life of the torsion sucker rod.

Due to the advantage of supersonic frequency heat treatment performance, increasingly customers recognized the product and ordered this sucker rodin recent years.

5.Anticorrosive Coating and Centralizer Sucker Rod

Application of our company’s invention patent “A kind of nylon modified anticorrosion coating ” (patent no. IL201310591953.5), was carried out on the surface of sucker rod coating processing. The surface has a strong adhesion, the material which can effectively prevent H ₂ S, CO ₂ and acid medium corrosion. At the same time molding centralizer, make the rod body does not touch the inner wall of the tubing, to prevent the corrosion layer wearphenomena and grinding. Which achieved the purpose of anticorrosion,and ensure that sucker rod is not wear, achieved the best anticorrosivewearing effect, at the lowest cost to solve the sucker rod used in corrosivemedium.
