25.40(1) Sucker Rod

1. The sucker rod is an important component in the sucker rod pumping system that is used to connect the ground pumping unit to the underground oil well pump. The products comply with Specifications of Sucker Rods (API Spec 11E) and other related standards, and they have acquired the Certificate of Authority to use the Official API Monogram. 3. Technical performance & characteristics ① With the advanced online testing, quenching, continuous tempering, and shot blasting process, the rod is large in mechanical strength and good in overall performance. ② The thread is processed in a non-rotary way with a dedicated CNC lathe and and rolled into shape, featuring high precision, reliable performance, and long service life.
