Sucker Rod
Sucker rod is steel rod that manufactured according to API SPEC 11B with C, D, H and K Grades. It is used to connect the pumping unit on the ground and the oil well pump down in the well. Sucker rod is an important part in the oil production system. Different grades of sucker rod has features of high strength, non-corrosive medium, good tensile and long service life.
