1. The design and calculation of heating tubes are generally carried out in the following three steps:
1. Calculate the power required to heat from the initial temperature to the set temperature in a specified time
2. Calculate the power required to maintain the temperature of the medium while maintaining the temperature of the medium unchanged.
3. According to the above two calculation results, choose the type and quantity of heater. The total power is the maximum of the above two kinds of power and 1.2 coefficient is considered.
Formula:
1. Power required for initial heating
KW= (C1M1 T + C2M2 T) 864/P + P/2
In formula C: C1C2 is the specific heat of container and medium (Kcal/Kg C).
M1M2 is the mass of the container and the medium respectively (Kg)
T is the difference between the required temperature and the initial temperature (C)
The time required for H to heat the initial temperature to the set temperature (h)
Heat Dispersion of Container at P Final Temperature (Kw)
2. Power required to maintain medium temperature pumping
KW=C2M3 Delta T/864+P
In formula: M3 adds medium kg/h per hour
3. Environmental Performance Curve of Heating Pipe
How to Choose
Common customers use stainless steel 304 material most. The working environment of double-ended heating pipe manufacturers is generally divided into dry burning and liquid heating. If it is dry burning, such as for oven and air duct heater, it can be made of carbon steel or stainless steel 304. If it is heated liquid, if it is water, use stainless steel electric heating pipe, this stainless steel is generally stainless steel 304 material, if it is oil, can use carbon steel or stainless steel 304 material. Stainless steel 316 can be used if it contains weak acid and alkaline liquids. If there is strong acid in the liquid, stainless steel 316, PTFE or even titanium tube should be used.
