What is a special-shaped electric heating tube

A special-shaped electric heating tube is a type of metal tube that is uniformly distributed within a stainless steel tube. The resistance wires are densely packed in the gaps, and the thermal conductivity and insulation properties are both crystalline magnesium oxide. This structure is not only advanced and has high thermal efficiency, but also has an electric current generated by the resistance wires when the heat is uniform. The heat generated by the current is diffused to the surface of the metal tube through crystalline magnesium oxide powder, and then heated or air is used to achieve the heating purpose. It has good mechanical strength, can be bent into various shapes and has safety functions.
We can produce various electric heating tubes according to customer drawings and technical requirements. The materials of the components can be manufactured according to customer requirements. There are stainless steel, nickel based alloys, copper, aluminum, carbon steel, and heating elements.
The electric heating tube has a simple structure, long service life, high thermal efficiency, good mechanical strength, and can be bent into various shapes, ensuring safety.

Power calculation method:
1. Calculate the power required to heat from the initial temperature to the set temperature within a specified time period.
2. Calculate the power required to maintain temperature without changing the temperature of the medium.
3. Based on the above two results, select the heater model and quantity. The total power is taken as the value of the above two types of power and the coefficient of 1.2 is considered.
Formula:
1. Power required for initial heating KW=(C1M1T+C2M2T) ÷ 864/P+P/2
In the formula, C1C2 represents the container and specific heat (Kcal/Kg ℃), M1M2 represents the mass of the container and medium (Kg), T is the difference between the required temperature and the initial temperature (C), H is the time required for the initial temperature to be heated to the set temperature (h), and (KW) the container at temperature
2. Power required to maintain medium temperature pumping KW=C2M3T/864+P
Among them: M3 increases medium kg/h per hour
3. Environmental performance curve of heating tube
