The Hollow Rod is a specialized sucker rod designed for oil extraction applications, particularly in conditions involving high viscosity, high pour point, and high wax content crude oil. This product plays a crucial role in the petroleum industry by facilitating efficient extraction processes while ensuring durability and longevity. It is made from seamless steel tubes, ensuring excellent mechanical strength and resistance to wear. The rod is available in multiple diameters, thicknesses, and lengths to suit various operational requirements. The hollow structure allows for the injection of hot oil, steam, and chemicals, helping to reduce viscosity and wax deposition, thereby increasing pump efficiency.
The Hollow Sucker Rod is specifically engineered for oil extraction in environments where crude oil has a high solidification point, making conventional extraction challenging. This rod is made of high-strength seamless steel tubing and features threaded joints connected through friction welding and heat treatment. The pin threads are formed using roller processing, ensuring precision and strength.
Key benefits include high torque resistance, enhanced rigidity, and the ability to accommodate heating cables within the hollow structure. This unique design enables multiple applications, such as flushing sand and salt, injection of chemicals, and running electric heating cables for improved oil extraction. The rod's construction provides excellent mechanical performance and extended service life, making it an ideal solution for modern oilfield applications.
The Hollow Rod is available in the following diameters and thicknesses:
| Diameter | Thickness | Nominal Thread | O.D. Joint | Wrench Size | Length (Rod) | Length (Pony) |
|---|---|---|---|---|---|---|
