Conventional Hollow Sucker Rod
價格：元
The Conventional Hollow Sucker Rod is a specialized rod designed for the effective extraction of "high pour point, high viscosity, and high wax content" crude oil. It allows for the injection of heat transfer mediums (such as hot oil, hot water, or steam), chemicals, or heating cables through its central bore to reduce viscosity, dissolve wax, and improve crude oil flow. Additionally, it can be used for sand washing, desalting, small-diameter well oil extraction, and layered oil extraction. Its high rigidity and torque-bearing capacity also make it suitable for driving downhole screw pumps.
