All kinds of industrial equipments and large workpieces need to be preheated before welding and local heat treatment for stress relief after welding. In order to improve the quality of the workpiece and strengthen the regional toughness of the pipe heater. At present, in large workpiece or field, the traditional methods of equipment maintenance are traditional, inefficient and energy-consuming high-frequency heating, flame heating or special manufacturing of superheater for heat treatment.
In addition, the drying and high temperature heating of metal containers are old methods. For example, steam pipe heating and indirect conduction heating of water-oil separator can not meet some high-temperature heating requirements, and the container is bulky, labor-intensive and difficult to repair. (2) To destroy the container, the insertion heating method of electric heating rod is adopted (some materials are not allowed to contact with the heater or contaminated materials after the damage of electric heating rod, and materials should be released before they can be carried out during maintenance). (3) Connecting ordinary porcelain tubes in series with electric furnace wires and winding external heating method (the ceramic tubes are in line contact with containers, the contact surface is small, the thermal efficiency is low, and the ordinary porcelain pieces are fragile and unsafe).
Crawler heater replaces the traditional and backward methods mentioned above. It is an ideal product for local heating, field heating and external heating.
