API 11B polished rod/sinker bars/Grade D Petroleum sucker rod
We can supply sucker rods,polished rods and sinker bars.
Sucker rod
Grade C sucker rods are made of high-quality alloy steel, with moderate strength, great plasticity and good corrosion resistance etc. Grade C sucker rods can be used in weakly acidic media without sulfurized stress fracture.
Grade D sucker rods are made of high-quality alloy steel, with moderate strength, great plasticity and lifespan after heat treatment. Grade D sucker rods can be used in rather deep oil wells with a corrosion-free or mildly corrosive environment
Polished rod
Polished rods with the same exterior threads at both ends (cone angle=9°), including three specifications: 1-1/8", 1-1/4" and1-1/2". End upset polished rods including three specifications: 1", 1-1/8" and 1-1/4". The upset ends are the same with those of sucker rods. In application, the upset ends are connected with the couplings of sucker rods.
