Steel sucker rod is important equipment for oil field. Anson sucker rod is produced based on C, D, K grade according to API Spec 11B，which is also our leading products.
C-class high-quality carbon steel rod is made by SSYD-1 (equivalent to AISI1526), with moderate strength, good plasticity, phase against corrosion and other specifics for the environment of an acidic medium without causing sulfide stress cracking. Grade D sucker is made of high-Cr-Mo alloy structural steel 30CrMoA (equivalent to AISI 4130), with high strength, good plasticity, long life and other characteristics, applicable to non-corrosive or slightly corrosive environment of deep wells. Grade K sucker rods are made of high-grade Ni-Mo alloy structural steel 20Ni2MoA (equivalent to AISI 4620), with moderate strength, good ductility, corrosion resistance and other characteristics, suitable to be used in light loads and shallow wells in the presence of corrosive media.

According to API standard design, sinker bars are made of domestic high-quality carbon steel or alloy steel. Both ends have the same external threads. According to the standard level, it is divided into 1 and 2, which can be connected with the upper end of rod well, or the lower end of the oil well sucker rod as well.
