Based on API Spec 11B, SY / T 5029 specifications, Sunrise Petro has developed a series of special sucker rods suitable for different well conditions, especially under high corrosion and high load conditions for oil well. We can also design and manufacture according to the parameters and requirements provided by client, if client needs different specifications and models.
High strength means high tensile strength in physical performance. Sunrise Petro can manufacture high strength and ultra-high strength sucker rod with high quality. We have rich experience in production and a strong ability in research and development. Our products include various series of high strength and ultra-high strength sucker rod based on client requests.
High torque sucker rod is one kind of special sucker rod, which has higher torsional strength and more stable connection, also known as drive rod, suitable for the Progressive Cavity Pump as well as screw pump. Sunrise Petro can manufacture high torque sucker rod with excellent comprehensive mechanical performance. These high torque sucker rods have novel structure, reliable performance, long service life and superior efficiency.
The hollow sucker rod, including hollow pony rod, is one kind special sucker rod designed for oil extraction of high pour point, high viscosity and high wax content. It is combined with threaded joints, sealing and rod body. Sunrise Petro can supply hollow sucker rods to meet the specific needs of clients.
With the increase of working time, conventional sucker rods are prone to corrosion and eccentric wear during operation, and are not suitable for high-strength or harsh working conditions. To solve the eccentric wear and corrosive problems in oilfields, Sunrise Petro developed various anti-corrosion and anti-abrasion products, including tungsten-plated sucker rod.
With the increase of working time, conventional sucker rods are prone to corrosion and eccentric wear during operation, and are not suitable for harsh working conditions. In 2012, Sunrise Petro developed a fully coated sucker rod. By using HDPE resin to fully coat the sucker rod body, the anti-corrosion and anti-abrasion of the sucker rod is realized. And this tech of SunrisePetro has gained patent in China, Canada and the United States.
Steel continuous sucker rod refers to the metal continuous sucker rod. Its cross section is approximately oval, which can be used in the conventional pumping unit and the oil pump. The continuous sucker rod has reliable performance, long service life and superior efficiency. With continuous development of manufacturing technology and material properties, the application of continuous sucker rods is more and more extensive. Sunrise Petro owns rich experience in manufacture steel continuous sucker rod.
Carbon fiber flexible sucker rod or carbon fiber reinforced plastic continuous sucker rod (CFRPC) is ribbon shaped and can be wound on the drum. Its cross section is rectangular. Sunrise Petro owns rich experience in CFRPC manufacture.
Compared with metal materials, FRP products have unique advantages such as light weight, corrosion resistance and good fatigue performance. After more than ten years of development and research, FRP sucker rods have been successfully trial manufactured with FRP materials. Field application shows that FRP sucker rods have great development potential. Sunrise Petro can supply FRP sucker rods to meet the specific needs of clients to all over the world.

The sucker rod with clamping protects bush
At present, the anti-wear and anti-corrosion sucker rod is made of common sucker rod by outer wall coating, injection molding or outer wall plating. It has high anti-corrosion performance for various corrosive media to extend service life and reduces the operation cost. However, one disadvantage is during sucker rod unloaded, the anti-corrosion layer at the wrench square will be bitten by the wrench, exposing the sucker rod body. This leads to local corrosion of the sucker rod when downhole operation and reduce the service life.
To solve this problem, Sunrise Petro invented one kind of anti-abrasion and anti-corrosion sucker rod with a clamping protecting bush. When connecting or removing the sucker rod, the wrench locks the clamp protective bush to avoid partial concentration of the sucker rod corrosion causing failure and prolongs the using life of external anti-corrosion sucker rods.
The anti-abrasion and anti-corrosion sucker rod with clamp protecting bush is mainly composed of the rod body, protective layer and end threads, as shown in the following figure:
The main working principle of the anti-abrasion and anti-corrosion sucker rod with clamp protective bush is as follows: the end thread is provided with a clamp protective bush matched with it, and the gap between the clamp protective bush and the rod body is filled with stuffing, the filler is a non-metallic anti-corrosion material, there is a overflow hole on the clamp protective bush, after the filler is completely filled, the overflow and flash are removed, and there is a thickened end between the thread on the end of the sucker rod and the rod body.
There is a relief groove between the thread and the thickened end, there is a transition arc between the thickened end and the rod body, the clamp protective bush is screwed on the thread end, and the exposed part of the end thread can be connected with the conventional sucker rod coupling connection, apply sealing material before screwing buckle the clamp protective bush with sucker rod end thread to prevent liquid from entering the thread gap and causing corrosion.
The gap between the transition arc of the protective bush and the sucker rod is filled with stuffing to ensure that there is no bare place on the sucker rod body at the transition arc.
When loading and unloading the coupling, the wrench is clipped on the clamp protective bush, which can prevent the anticorrosion layer at the sucker rod outer anticorrosion layer is bitten by the wrench.
The anti-abrasion and anti-corrosion sucker rod with clamp protective bush has simple structure and is convenient to manufacture.
It can avoid the bite of the anti-corrosion layer at the side of the sucker rod wrench during operation, which can greatly improve the anti-corrosion ability of the outer anti-corrosion layer and extend the sucker rod using life.
