API Sucker Rod, Pony Rod and Sucker Rod Centralizer Guide Supplier

1. Description:

Sucker rod is a kind of steel rod used to transfer the movement and power of pumping unit to the downhole pump.

Sucker Rod adopts ultra audio induction quenching technology to further process from Grade D sucker rod. The metallographic structure is acicular martensite; the crystalline grain is fine and even. After shot- blasting, the rod has higher tensile strength (980~1200 MPa), surface hardness (HRC≥42) and surface residual compress stress (≤-200MPa). The rods have higher fatigue strength.

The unique of the ultra high strength sucker rod is that the rod has a thin compression layer 10-15% at the rod surface that remains under compression even under normal operating tensile loads.

2. Characteristics:

1）  Grade C sucker rod is made from fine carbon steel. It is featured by mid-strength, good plasticity, toughness, corrosion resistance. It is suitable for sour medium environment where it is not susceptible to sulphuric stress cracking.

2）  Grade D sucker rod is made from fine alloy steel, featured by high strength, better plasticity and long service life after heat treatment. This product is suitable for no-corrosion or light-corrosion environment oil-well widely.

3） Grade HL and HY sucker rods are super-high strength sucker rod, having the same size and main parameter as grade D sucker rod, but their strength is capable to reach 966~1195Mpa. Grade HL, HY sucker rods are suitable for the deep oil-well or big-pump capacity oil-well.

4） And grade K, KD and KH sucker rod are made from fine Cr-Ni-Mo alloy steel containing different amount of Ni. They possess more powerful anti-corrosion function. The products are suitable for strong corrosion oil-well, with depth of shallow, middle and deep respectively.

3. Advantages:

1) Energy saving through pumping with a lighter string with no compromise in production;

2) Higher fluid production with existing pumping unit;

3) Reduction in the size of pumping  unit with no reduction in production;

4) Increase pumps speed for additional production;

5) Extended service life and cost saving.
