1. Product introduction of double head tube
The double-ended electric heating pipe is an electric heating pipe with double-ended outlet. The metal pipe is used as the protective shell (including stainless steel, red copper pipe, and various types of steel), and the spiral electric heating alloy wire (nickel-chromium) is evenly distributed along the inner axis of the pipe. , iron-chromium alloy heating wire), and the gap is tightly filled with crystalline magnesium oxide powder with good heat resistance, thermal conductivity and insulation, and both ends of the nozzle are sealed with silica gel, which is processed by other processes. The heater has the characteristics of simple structure, easy installation and long service life. With its strong advantages, it is widely used in air heating, metal mold and various liquid heating.



2. Classification of double-headed tubes
Double-headed electric heating pipes are generally divided into: U-shaped electric heating pipes, threaded installation electric heating pipes, double-headed finned electric heating pipes, double-headed electric heating pipes, water heater heating pipes, etc.
3. The use environment of the double-headed tube
Double-head electric heating tube used in air: 1. Closed air heating 2. Air heating 3. Special gas heating
The use of double-head electric heating tubes in liquids: 1. Heating in water 2. Heating in oil 3. Heating acid and alkali liquids (the heating area of the electric heating tube should be immersed and not exposed to the air) The watt density and material used are different and should not be confused Use, a good use environment should not produce peeling, thinning, oily, watery and other phenomena.
