Description of sucker rods:
We can supply sucker rods,polished rods and sinker bars.
Sucker rod is the common equipment in the oil extraction. It is manufactured through many process including the testing, straightening and forging. The sucker rod is placed between the polished rod and oil well pump. To deliver power. Sucker rod is manufactured from high quality carbon steel and alloy steel, which is conform to the API Spec 11B standard.
Features of sucker rods:
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.
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.
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.
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.
