An electric heating pipe

Abstract

The invention discloses an electric heating pipe. The pipe comprises a pipe A and a pipe B. Pipe bodies are arranged in both the pipe A and pipe B. the left and right ends of each pipe body are welded with hanging hooks. The outer walls of the pipe bodies are coated with an insulation heat conducting layer. Electric heating wire components are laid on the outer side of the insulation heat conducting layer. Multiple electric heating components are parallelly connected in two stages with ceramic wiring terminals. The outer sides of the electric heating wire components are coated with insulation heat preservation protection layer. The outer side of the insulation heat preservation protection layer is coated with an outer shell. Lead wire locking mother holes are formed in the outer shell. Electric heating lead wires and temperature probe lead wires pass through the lead wire locking mother holes to be connected with a host machine. It is guaranteed that the electric heating pipe is not only capable of controlling the temperature accurately, and being produced in bulk, but also is convenient for construction and maintenance, thus providing a product which saves more energy, more environmental protection features and higher operation efficiency, and a better technological method for the aim that the electric heating pipe can replace other types of pipes.

Description

technical field [0001] The invention relates to the technical field of pipeline heat tracing, in particular to an electric heating pipeline. Background technique [0002] Problems that arise during the use of existing electric heating pipelines: 1. The temperature measured at a certain point in the long-distance pipeline does not represent the temperature at other locations one meter away. Using the temperature at this point to control a longer pipeline will cause the entire section Pipeline temperature control is not allowed. 2. Electric heating construction is difficult. During the construction of electric heating, problems such as waterproof, anti-collision, anti-high temperature, fire prevention, and insulation safety will be encountered. 3. Partial small-scale production cannot be standardized in batches. [0003] In addition, in the production of pipeline transportation, the current situation of pipeline heat tracing mainly uses water, steam and heat transfer oil as ...

AI Technical Summary

Problems solved by technology

[0002] Problems that arise during the use of existing electric heating pipelines: 1. The temperature measured at a certain point in the long-distance pipeline does not represent the temperature at other locations one meter away. Using the temperature at this point to control a longer pipeline will cause the entire section Inaccurate pipe temperature control

2. Electric heating construction is difficult

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; regular cleaning costs for boilers and heat exchange equipment; environmental protection costs for boiler emissions; steam and water heating systems are shut down in winter to prevent freezing of pipelines; circulating heating equipment pumps, valves and fittings Seal wear and aging, daily maintenance and replacement; 6. Poor thermal efficiency. Due to the huge heat 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, It is not necessary for pump and valve insulation to be unfavorable for heat loss

[0004] Therefore, the existing heat tracing pipes in the market have high environmental protection costs, large health and safety hazards, high management and operation costs, low energy consumption efficiency, difficult batch construction standardization, and difficult maintenance. These are the current status of heat tracing pipes or electric heating pipes.
