Disadvantages of the heating method of stainless steel electric heating tube:

1. Because the heating of the stainless steel electric heating tube needs to be conducted through magnesium powder and then through the metal shell to conduct the heat to the heated object, there is a certain amount of heat loss compared to direct heating, but as the heating tube manufacturing process becomes more and more mature , this heat dissipation has become smaller and smaller.

2. The stainless steel electric heating tube has a slightly higher cost than heating methods such as resistance heating and infrared heating because the shell is made of metal, but it is safer in use and transportation.
