SUCKER ROD
A steel sucker rod is one of the important equipment of oil field. It includes six grades of sucker rod, including C, K, D, KD, HL and HY. C, K, D grade sucker rod are designed and manufactured according to standard of API Spec 11 B; KD, HL, HY grade rod are designed and manufactured according to standard SY/T5029-2006.
C grade sucker rod series - is mainly used for light, medium load, no corrosion or corrosion shallow Wells or in deep well pumping, material is carbon steel or manganese steel.
