Product Description

                    API  11B  7/8'' Class D Sucker Rods for Oil Drilling

Sucker rod is among our leading products absorbing technical essence from home and abroad in accordance with API SPEC 11B,SY/T5029, applying the advanced technology in market  and special material developed and  anti-corrosion sucker rod, cooperating with international leading manufacturer to produce several sorts of sucker rod such as Grade HLHYKDD  with different properties consisting of high strength and toughness, anti-corrosion and surface spray, used in major oilfield home and abroad. The capacity of sucker rod is 5,000,000meters per year, making good returns through high added value. 

 

 

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 C: suitable for sour medium environment where they are not susceptible to sulphuric stress cracking.

 

grade D: suitable for the deeper oil well in the non-corrosion or light-corrosion medium.

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.
