Heating threads are wound around the inner jacket insulation layer. Every certain distance the heating thread is welded to the generatrix,which makes the continuous parallel connection resistance. When the generatrix is powered, the parallel connection resistance begin to heat. This makes a continuousheating belt.

The electric heating belt can be cut flexibly according to the actual needs. And it is flexible and can be laid closely on the pipe surface. The outer brade layer can execute the function of heat transmitting and radiating, to enhance the general intensity of the heating belt. It can also be earthed.
