When communicating with customers about the technical parameters of single head tubes, we must determine the specific size, power, and working environment of the electric heating tube. Why do we attach so much importance to these parameters? On the one hand, we only need to know these parameters in order to customize non-standard production, and on the other hand, we must use them to calculate the surface load of the heating tube. The surface load of the heating tube is extremely important for the electric heating tube.
The surface load of the single head tube continuously affects how we choose the material of the electric heating tube, and also affects our judgment of whether the power setting of the electric heating tube is reasonable. At the same time, we can also determine the surface temperature of the electric heating tube (extension: how to know the surface temperature of my heating tube?).
The size of the surface load on a single head tube is also limited by the usage environment. Heating liquids, air dry burning, mold heating, etc. all have different surface loads. Simply put, this is related to thermal conductivity and heat balance. The parameters used here roughly include: 1. Normal air dry burning 6-8W/cm ^ 2; 2. Normal liquid heating 6-15W/cm ^ 2; High power usage of 12-20W/cm ^ 2. Sometimes other factors need to be considered here, such as dry burning, external fins, and corrosive liquids, which indirectly affect the selection of materials and thus affect power production.
In summary, the surface load of a single headed tube is a crucial technical parameter for our single headed tube manufacturers.
