Product Features
Continuous steel pipe heating system is an electric heating system that combines heat and thawing in oil and gas mining, liquid and gas pipeline transportation. Because the cable sheath is steel pipe, it is used with P46, polyethylene, polypropylene and other materials. Compared with the characteristics of high mechanical strength, high extrusion resistance, oil resistance, pressure resistance, corrosion resistance, high temperature resistance, long life and renewable, it is widely used in the petroleum industry: “Petroleum exploration, oil mining, refining Processing, storage, gathering and other production processes.

Working Principle:
 
   The cable is powered by single-phase power; the copper core is used as a conductor, and the steel pipe sheath is used as a heating element. At the lower end of the cable, the copper core and the steel pipe sheath form a loop through the circuit joint. After the power is applied, the two current-carrying conductors basically form the same current and opposite directions, and the skin effect is generated on the inner wall of the steel cable sheath. The combination of iron loss and proximity effect generates heat, realizes electrothermal conversion, and achieves heating purposes.

This product can effectively conduct heat and has the characteristics of strong tensile strength compared with conventional cables, especially when the oil pipe or hollow rod is oiled. Moreover, it completely overcomes the defect that the cable skin is easily damaged, and greatly reduces the occurrence of short-circuit accidents, and is safe and reliable. In the case of repeated operations, if fracture occurs, it can be welded and reused, and has strong repairability.
