Sucker Rods
Sucker Rods and Couplings are manufactured in accordance with API specifications. Sucker Rods with standard length being produced at present time, include 4 grades: Grade C.D.K and H and 4 sizes: 16mm (5/8"), 19mm(3/4"), 22mm(7/8")and 25mm(l"). Besides, there are various sizes of pony Sucker Rod and conventional/reducing couplings available. The Sucker Rod is an important equipment of the mechanical production system, they are API conventional Sucker Rod, solid Sucker Rod with special structure, corrosions resistant sucker rod, FRP (fibre glass reinforced plastics) Sucker Rod, polished Sucker Rod and couplings, special purpose sucker rod for progressing cavity pump, hollow Sucker Rod and electro heating system. All kinds and sizes of Sucker Rods are available to meet the requirements of different well conditions. Sucker Rods and couplings are made of high quality steel; they feature elaborate design and manufacturing technology, reliable performance and long service life.
