Product News

Pass a cable through the hollow sucker rod, creating a circuit with the rod itself. When alternating current is applied, the inner skin effect generates heat directly within the walls of the hollow sucker rod, providing continuous heating to the crude oil inside the tubing. This process raises the temperature of the crude oil, reducing its viscosity and enhancing its flowability. Additionally, it prevents wax deposition inside the tubing, enabling efficient extraction of highly viscous, high-wax-content, and heavy-crude oils—especially those with challenging flow characteristics.
