Our company often has to deal not only with the tasks of local heat treatment. There are such problems where the application of local heat treatment is not profitable or economically justified. An example of such a task is the heat treatment of welds of spiral-welded or longitudinal pipes of medium and large diameters.
In this case, the use of local heat treatment with ceramic heating mats is disadvantageous because the installation and dismantling of the heating system will take a long time.
Therefore, with a large amount of work, it is advantageous to build a temporary electric furnace in which heating panels can be used as heating elements, and the process can be controlled powerfully from the corresponding control unit.
The process of loading and unloading pipes from a temporary heat treatment furnace is carried out by a crane through a removable roof.
