Iron and steel are produced through blast furnace gas, which contains special substances and has a very high concentration in the gas scrubber water, and therefore needs to be cleaned frequently. In winter, when the blast furnace gas is cleaned with scrubber water after power generation, the medium in the pipeline freezes, causing residue to remain in the pipeline, which affects the quality of the steel.

 　　              In order to ensure the quality of steel and pipeline circulation, need to install insulation facilities, and nowadays the steel blast furnace gas pipeline choose electric accompanied by heat tape is a better way of insulation. Uses the electric heating cable system heat preservation because the electric heating cable to be new accompanies the heat preservation way, the installation is convenient, accompanies the heat efficiency high, may realize the automatic temperature control or carries on the temperature setting through the thermostat to control the temperature.

 　　              Iron and steel blast furnace gas pipeline using electric heating cable system with positive temperature coefficient “PTC” characteristics, can be heated with the temperature change of the object changes, without temperature controller, can control the temperature by itself. The electric heating trace cable can be cut arbitrarily, no high temperature hot spot and burning worry.

　              The electric heating cable system can solve the phenomenon which the medium freezes inside the iron and steel blast furnace gas pipe very well, it can adjust the temperature by itself according to the actual environment of the scene and the temperature of the medium itself, achieves the purpose of energy saving. At the same time the use of electricity as energy, has a clean, safe and reliable characteristics, so now all areas can see the use of electric heating trace cable system, the effect is also praised by the user.

　　         Electric heating trace cable product not only applies in the iron and steel blast furnace gas pipe antifreeze heat preservation, also applies in the chemical industry, the petroleum, the fire protection, the food and the household water pipe and so on, because of its wide application, the installation is simple, the maintenance is simple, the energy conservation and so on the characteristic, deeply each profession's trust.
