API Sucker Rod, Polished Rod, Pony Rod at China factory competitive price

6) Description

The sucker rod is a steel rod that used to transfer the movement and power of pumping unit to the downhole pump.

Polished rods are designed for connecting sucker rod strings to beam pumping units via polished rod packing. The rods are round cross-section bars.

Pony rods are sucker rods shorter than 25 ft, and they vary in length. They are most commonly placed adjacent to the polished rod at the top of the rod string, on top of the downhole pump for handling purposes, and on top of the polished rod with appropriate couplings to prevent the string from falling downhole if the polished-rod clamp slips.

7) Features

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.

8) 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.
