API oilfield equipments, Sucker Rod

The rods are high in quality and reasonable in price. Basic material: AISI 4135&4142 Standard: API SPEC 11B  Technical Performances1,Adopting the advanced production line crack detecting, quenching, the continuous overall tempering and sand blasting processes to achieve higher mechanical strength ability with overall good performance.2,The thread is cut by the special-purpose numerical control lathe which keeps the rod body still when cutting the threads. The special process could ensure the high precision of the thread with better reliability and life-span.
