Medium Temp: -40℃~+200℃; Physical propertiesGross Densityg/cKJ/KHeat ConductivityW/MSoft Temp.°C1400Maximum Application Temp.°C1350Corrosion Resistance Against Acid%99.5Chemical content of each material is as below:Power and surface load of heater tubeSurface load,that is,the electric power value taking on on unit superficial area of heating e higher surface use load strength of material is,the shorter life of material is,but the smaller the wastage of material heating load strength of element should be chosen reasonably,making the heating element have general effect of high thermal efficiency,long life,lculating step is as below:sic data for calculationThe highest use temperature t (C)Heating electric power P (W)Working voltage of element U (V)Length of heating zone L(m)e electrothermal alloy brand in use is confirmed according to basic databining with working condition of heating sed on the confirmed electrothermal alloy brand in use,referring to known data,check attached table and get coefficient of correction Ct of resistance temperature.4.Work out total resistance of material=U2 Ct/P5.Work out resistance of per meter material Rm=R/Lbine the property of electrothermal alloy material and estimately work out the diameter of material en work out total area FO of heating e surface load of material ω is gained by ω=P/FO.If the load of surface is too large,big diameter of wire should be rrently because of limitation of heating should not exceed 2.0W/ can be improved properly in the condition of low temperature.
