管道电阻加热系统(阻抗加热)
Pipeline resistance heating system (impedance heating)

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.

电预热电源系统(直埋供热管道专用)
Electric preheating power supply system (special for directly buried heating pipeline)

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.
