Description

technical field [0001] The invention relates to the technical field of electric heat tracing, in particular to an electric heat tracing production process system. Background technique [0002] In the process of liquid pipeline transportation, there are often pipeline heat tracing production processes. This process adopts a large number of three modes: water circulation jacket heat tracing, heat transfer oil circulation jacket heat tracing, and steam jacket heat tracing. , steam, and heat-conducting oil are used as the medium, and the heat preservation and constant temperature transportation of the fluid in the pipeline are completed by means of heat exchange of the circulating fluid in the pipeline jacket. The heating media such as water, steam, and heat transfer oil must be equipped with boilers and heat exchangers. With these equipments, there are problems of environmental protection, efficiency, and maintenance. For example: 1. Running, popping, dripping, and leaking phe...

AI Technical Summary

Problems solved by technology

The heating media such as water, steam, and heat transfer oil must be equipped with boilers and heat exchangers. With these equipments, there are problems of environmental protection, efficiency, and maintenance.

For example: 1. Running, popping, dripping, and leaking phenomena; 2. Complex and huge heating, heat exchange, and circulation equipment are required; 3. Long-term use, deposition in the cyclic heat tracing cavity produces heat tracing blind spots

4. Corrosion, perforation, leakage and contamination of heated fluid materials, especially food and medicine

5. High maintenance costs, such as heat transfer oil aging and volatilization, need to be added and replaced regularly; boilers and heat exchange equipment are cleaned regularly, environmental protection costs; steam and water heating systems are shut down in winter to prevent freezing of pipelines; circulating equipment pumps, valves, pipe fittings, sealing wear and aging daily Maintenance and replacement; 6. Poor thermal efficiency. Due to the huge thermal cycle heat exchange system, this part of the equipment (such as boilers, heat exchangers) has loss of operating efficiency, cycle power loss, heat exchange loss, circulation pipeline, pump, valve insulation Unfavorable heat loss is unnecessary

In terms of pipeline electric heat tracing, due to the nature and characteristics of pipelines: such as long crossing distances, difficult temperature control and temperature measurement points, and many environmental changes (such as geographical sections, overhead sections, high temperature areas, humid areas, underwater explosion-proof areas, Indoor and outdoor sections, building mezzanines, etc.) have made many electric heating products such as heating cables, metal heating wires (MI wires), and high-frequency drivers in the field of pipeline heating efforts to promote, once used in engineering, there will be corresponding problems : Insulation problems, fire and explosion-proof problems, life problems, protection strength, waterproof and anti-corrosion, due to the above problems, in terms of pipeline electric heat tracing, various manufacturers are improving related products by themselves, and many problems are not the problems of the products themselves, but the on-site problems. The construction technology restricts the promotion of pipeline electric heat tracing, and the key to solving the above problems is to standardize the electric heating pipeline products and improve the construction technology.
