Smart Electric Heating Device for Hollow Sucker Rods
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.
Sheathed Explosion-Proof Electric Heating Rod
The sheathed electric heating rod features a nickel-chromium wire heating element encased within a rod-shaped outer shell. The cable is routed through a junction box, allowing the unit to be inserted from the bottom of the container during installation. This design makes it ideal for heating or heat-tracing applications involving liquid media in various storage tanks.
This product is available in two models: oil-filled and radiant types. The oil-filled model has a thermal conductive medium injected inside the rod; once the electric heating tube warms up this medium, the resulting heat is efficiently transferred to the rod’s protective sheath, ultimately warming the surrounding medium. In contrast, the radiant type uses the high temperatures generated by the heating tube to directly "bake" the rod itself, raising its temperature significantly for effective heating.
Immersive electric heater
An immersion-type electric heater consists of multiple heating elements welded onto a flange, creating a high-power, fully assembled and disassemblable heating unit. A temperature-sensing probe is also welded directly onto the flange, resulting in an integrated heater with precise temperature control. This type of heater is primarily used in applications where direct contact heating of fluids is required, offering rapid heat transfer and exceptional thermal efficiency.
