JL Type Crawler Heater - Yangzhou Darui

Darui Electric recommends
JL type crawler heater is made of high-temperature resistant multi-strand superior nickel-chromium wire and superior ceramic insulators woven according to special technological requirements. It is a novel heater with arbitrary bending characteristics in its length direction. Due to its high strength and flexibility, this heater is widely used for preheating and stress relieving of various metal containers, pipes, steel frames, and castings. It can also adapt to workpieces with geometric shapes. If several pieces are used together, they can be laid flat to cover large-area workpieces. It can also be wrapped around pipes of "4-25" (feet) for preheating and post-weld heat treatment. If used properly, it has a long service life.
II. Remarks

1. The dimensions and matching power of the heater can refer to the table above. Special needs can be customized.

2. The width of the heater should be 7 to 10 times the wall thickness of the heated object.

3. According to user needs, we can supply complete sets of lead cables, thermocouples, insulation covering materials, special temperature control cabinets, and capacitor welding instruments.

4. Power tolerance is ±3%, and dimension tolerance is ±2%.
III. Usage Precautions
