Shandong Huaning Electric Heating Technology Co., Ltd.
1. Application Brief
Depending on the different substances of the fluid in the pipeline, the temperature maintained in the pipeline is also different. The industrial frequency surface effect electric heating pipeline technology is mainly used for heating the pipeline and heating, melting or intermittent transportation of oil. Liquid or solidified medium in the pipeline. There are two ways to collect the skin inside the tube and collect the skin outside the tube.
① Oil fields, offshore platforms: production pipelines, crude oil, steam pipelines, water pipelines, pulse lines, instruments, storage towers at centralized stations, main pipelines, etc. D. The bottom of the river, the bottom of the lake, the underwater oil pipeline.
②, refining industry, distillation, hydrocracking, coking, paraffin, vulcanization, asphalt, residual oil and other production pipelines, water pipes, pulse lines or tools, storage towers, liquid hydrocarbon storage towers.
③Petrochemical plants, chemical plants, chemical fertilizer plants: benzene, styrene, polyethylene, chlorine, acrylic acid, oxalic acid, ethylene glycol, phthalic aldehyde, synthetic fiber, nylon, dye paints, resins and other production pipelines; Water pipes, pulse lines or meters, storage towers, Liquid hydrocarbon storage towers.
④ Nuclear power plants: heavy water pipelines, water pipes, pulse lines and appliances, water towers, heavy water towers.
⑤ Petroleum pumping station: oil storage towers, trunk pipelines, low-temperature oil product tower foundations, and pipelines and water lines connected to towers.
⑥ Power plants: high pressure water supply, wastewater ventilation, steam, degassing, high pressure condensation, acid-alkali, oil pipelines for fuel oil storage and other pipelines, fuel oil pipelines, fuel oil towers, pulse lines and appliances, water pipes, main pipelines, tubing for transportation of water-coal sludge, etc. D.
⑦ Metallurgical plant: production pipelines, fuel oil, coal tar, asphalt and sulfur, water pipes, main pipelines.
⑧ Cement Plant: Furnace or fuel oil line, water pipe, pulse line or tool, storage tower, fuel oil main line.
⑨, There are also plastics processing plants, edible oil processing plants, chocolate processing plants, water supply plants, hotels and high-rise buildings, and heavy engineering industries.
Heating skin: It can be divided into two types: external skin and internal skin. The above-mentioned different types of pipeline transport can use electric heating on the skin effect.
It is concluded from practice that this technical solution has achieved good transport effects and significant economic benefits.

FAQ
Why is the outlet temperature of the electric heater abnormal/the temperature cannot reach the required temperature?
Temperature controller failure, electric heating tube failure, control circuit failure, insufficient air volume or low air pressure inside the heater body, cooling fan damage, etc.
Why does the electric heater fail to heat?
The heating wire is burned out, the internal junction box or external line is broken or loose, the power supply phase is missing, the electric control board is damaged, etc.
Why does abnormal heating occur (overheating or no heating)
Improper design: Exceeding the maximum operating length of the heating cable results in excessive voltage drop and insufficient power. Overlapping heating: Overlapping parallel heating cables, if not self-limiting, can cause burnout due to the combined heat. Insulation issues: Lack of insulation, thin or uneven insulation, leading to heat loss and prolonged operation of the heating cable in low or humid conditions, affecting its efficiency and lifespan.
Causes of short circuits/open circuits
Installation damage: Repeated bending, dragging, or excessive flexing of the heating cable during installation can damage its insulation. Wiring issues: Improper installation of wiring accessories can damage waterproof seals, allowing moisture or corrosive substances to enter and cause short circuits or leakage. External physical damage: Activities such as pipeline maintenance, cross-operation, and equipment lifting can cause physical damage to the heating cable.
