Sunrise Petro can supply polished rods which comply with API 11B standard. They are manufactured through many processes including the testing, straightening and forging. Polished rods are made of high quality carbon steel and alloy steel due to customer request. Our polished rods are exported to the United States, Canada, Europe, and Middle East, and we establish cooperative relationships with international customers all over the world.
The polished rod is a special sucker rod for connecting the sucker rod and the beam hanger. Because it is located at the upper part of the sucker rod and bears the largest force, the diameter of the polished rod is larger than that of the sucker rod, the steel grade is higher, and the surface is smoother. The polished rod has mainly two types: regular grade D polished rod and end upsetting polished rod.
The regular grade D polished rods are connected by polished rod coupling.
