Heating rectifier power supply

Product Introduction to Pipeline Resistance Heating Systems (Impedance Heating): Pipeline resistance heating systems utilize the pipeline itself as the heating element, directly energizing and heating the pipeline with low-voltage, high-current electricity. The system comprises a power transformer, a control panel, and a flange isolation assembly, designed to maintain pipeline temperature or raise fluid temperature to prevent high‑pour‑point media from solidifying and causing blockages. Application: Thermal insulation for crude oil pipelines; heat tracing for pipelines transporting heavy oil, fuel oil, and molten media such as asphalt and sulfur; temperature maintenance for chemical process pipelines. Product features: The pipeline itself serves as the heating element, eliminating the need for additional heating elements and achieving extremely high thermal efficiency.

Electric preheating power supply system (special for directly buried heating pipelines) product introduction electric preheating power supply system is the core equipment specially used for electric preheating installation of directly buried hot water pipelines in cities and towns. The power supply is connected with working steel pipes through cables to form a closed loop, and alternating current is converted into low voltage and high current electric energy to act on the preheating pipe section. The pipe is heated to the designed preheating temperature by using the resistance heating principle of the steel pipe itself. The system consists of high-power transformer, control cabinet, terminal board, flange isolation kit, etc. Application of Urban Central Heating Directly Buried Hot Water Pipeline Installation Large Diameter Long Distance Heating Pipe Network Construction Cogeneration Cleaning
