The use of concrete in the construction work and project process is relatively common, but in the winter time, the temperature is below 0 ℃, the concrete will be frozen or solidified because of the climate, thus affecting the progress of the project, so it is necessary to prevent the concrete from freezing heat preservation, especially the concrete inside the pipeline heat preservation is very important.
At present, the use of more widely to be electric accompanied by heat system, in the petroleum, chemical industry, tunneling, electric power, steel and engineering construction pipeline can be seen electric accompanied by the application of tropical. The concrete pipe uses the electricity to accompany the heat preservation to be able to guarantee the concrete temperature during the construction period very well, reduce the concrete in the conveying project heat dissipation, thus make the construction project can carry on normally.
Electric accompanies the tropical installation is also relatively simple, accompanies the heat temperature is relatively uniform, which since the temperature-limiting accompanies the tropical can also realize the automatic temperature control, arbitrary shear, cross overlap winding. The concrete pipeline applies the electricity accompanies the heat preservation, also can use the self-limiting temperature accompanies the heat tape, this not only installs the maintenance convenience, also can save the economy.
The concrete pipeline electric accompanies the heat tape economy conveniently, the energy conservation environmental protection, can reduce the circuit and the control point, also can save the related accessories use. The electric accompanies the tropical belt also may according to the need to apply flexibly in each kind of pipeline accompanies the heat to keep warm, is the national key promotion accompanies the heat to keep warm the technology.
