Discription

a. 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.

b. 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.

 

c. 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.

 

d. 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.

 

Advantage

a. Energy saving through pumping with a lighter string with no compromise in production;
b. Higher fluid production with existing pumping unit;
c. Reduction in the size of pumping unit with no reduction in production;
d. Increase pumps speed for additional production;
e. Extended service life and cost saving.
