How long can the electric heating tube be used? This question cannot be quantified to a specific time, because there are many factors affecting the service life of the electric heating tube. It can be divided according to the heating medium:
1. Heat the liquid
Consider water quality, corrosive liquid, oil, heating pipe installation, power design is reasonable, whether there is dry burning, etc.;
2. Heat the air
Consider the electric heating tube itself surface load design and electric heating element material match (material is mainly classified as: metal sheath, insulating magnesium oxide powder, resistance wire and other materials), the working environment whether there is a fan circulation blowing, whether there is temperature control.If it is embedded dry firing, but also consider the fitting degree between the diameter of the electric heating tube and the aperture, whether there is a gap is too large, under normal circumstances, the gap between the two is between 0.1-0.2mm.
