In terms of lead-out rods, they are all metal conductive parts connected to the heating element for connecting components to the power supply and components to components. The unfolded length is the sum of the straight line and bending length of the metal tube on the component drawing. According to the testing conducted by the National Center for Quality Supervision and Inspection of Infrared and Industrial Electric Heating Products, 73% -78% of the far infrared wavelengths radiated by the electric heating film are mainly concentrated between 4-14UM. The electric heating wire generates heat in a linear shape, with a small heat dissipation area.

And the electric heating film generates heat in a surface shape with a large heat exchange area. After testing by the National Thermal Testing Center, the electric heating conversion efficiency reaches over 96%, while the radiation efficiency reaches 78%. Therefore, with the same power and temperature rise, it is more energy-saving and energy-saving than traditional electric heating components. For consumers, with the same heat sensation and heating effect, using electric heating film products can achieve the effect of spending 1600W to enjoy 2000W. It has an impact on the heating length and heating surface area of the electric heating tube. The unit of surface area of the metal tube on the heating length is cm square; The unit of power per unit area on the heating surface is W/cm square.

Safe use of electric heating tubes is very important for both equipment and machinery! The safe use of electric heating tubes not only ensures the normal operation of machinery but also effectively ensures production safety issues. There is one more point that needs special attention. The electric heating tube used should be fixed in position. The effective heating area must be completely immersed in liquid or metal solids, and empty burning is strictly prohibited. When scale or carbon deposits are found on the surface of the tube, they should be promptly removed and reused to avoid affecting heat dissipation and shortening its service life. During use, the maximum heat treatment temperature of the electric heating tube is 1300 degree . If this temperature is exceeded, the heating wire inside the electric heating tube will burn out.

The corrosion of the 304 material electric heating pipe occurs after heat treatment. The method to correct it during use is: the 304 material electric heating pipe undergoes a 1000 degree heat treatment in an ammonia separation gas mesh belt furnace, and the green substance on the surface is removed by chemical or physical methods before being immersed in water for heating. Otherwise, it may cause corrosion of the electric heating tube.
