With heat as an effective pipeline (tank) insulation and anti freezing project has been widely used. Its working principle is through the heat with the media to distribute a certain quantity of heat, through direct or indirect heat exchanger to supplement the loss of heat pipe with heat, in order to achieve the normal operation of heating, thermal insulation or antifreeze. In 1970s, the US energy industry put forward the idea of using electricity tracing scheme to replace steam heat tracing. In the late 80's and early 70's, many industrial sectors, including the energy industry, have been widely used in the field of electric heat tracing technology. With the development of electric heat tracing technology, it has been developed from the traditional constant power heat tracing to the automatic temperature electric heating with the core of conductive plastics.

Traditional steam or hot water heating is used in the process of the process of the technology of the process pipeline and tank vessel in our country. Electric heat tracing is used electric energy to supplement is with heating element in the process of loss of heat, so as to maintain the flow medium in the most reasonable process temperature, it is a kind of new and high technology products. Electric heat tracing is along the pipeline length or volume of the tank body of a large area of uniform heat release, it is different to a point or small area in a high concentration of heat load of electric heat tracing; electric with temperature gradient, heat stable time longer, suitable for long-term use, the heat (electric power) considerably lower than electric heating. Electric heating has high thermal efficiency, energy saving, simple design, convenient construction and installation, no pollution, long service life, and can realize remote control and automatic control, etc. is replaced by steam, hot water with heat technology development direction is countries focus on the promotion of energy-saving projects.

Cable connected to power (note the line at the end of the core shall not be connected), current by a wire through conductive PTC material to another line core and form a loop. Electricity conductive material is heated, then increased its resistance, when core temperature rose to a certain value, resistance to almost blocking the current degree, the temperature will not rise, electric tropical to low temperature heating system heat transfer at the same time. The power of the electric heating system is mainly controlled by the heat transfer process, and the output power is automatically adjusted by the temperature of the heating system, while the traditional constant power heater has no such function.

Electricity with heat and steam (hot water) compared to a number of advantages are as follows:

(1) the electric heating device is simple, uniform heating, accurate temperature control, can realize remote control, remote control, automatic management.

(2) thermal explosion proof, all-weather working performance, high reliability, long service life.

(3) electricity with no leakage, is conducive to environmental protection.

(4) save steel: it does not need to steam tracing and one to two times with heat pipe.

(5) saving insulation materials.

(6) saving water resources, not like the boiler needs a lot of water every day.

(7) electric heat tracing can solve the problem of steam and hot water with difficult to solve.

(8) the electrical heat tracing design workload is small, the construction is convenient and simple, and the maintenance workload is small.

(9) the efficiency is high, can greatly reduce the energy consumption.

A one-time investment or operating costs, electric tracing ribbon than steam with tropical to save; some projects with tropical electric one-time investment may will be slightly higher than the steam and hot water with heat, but the annual operation cost theory, usually electric heat tracing running 1-2 years save fee can recover investment.
