Product Description
API Sucker (Pony) Rod for Oil Well1. 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.4.
