The concept of electric heating pipe
Tubular electric heating elements (electric heating pipes) are made of metal pipes (including stainless steel and copper pipes). Spiral electric heating alloy wires (nickel chromium, iron chromium alloy) are evenly distributed along the center axis of the tube. Performance magnesia, both ends of the nozzle are sealed with silica gel. This metal armored electric heating element can heat air, metal molds and various liquids.
The metal tubular electric heater element (electric heating tube) is an electric heating element placed in a metal tube, and the gap part is tightly filled with crystalline magnesium oxide powder with good heat resistance, thermal conductivity and insulation. After being processed by other processes, to make. It has the characteristics of simple structure, high mechanical strength, high thermal efficiency, safety and reliability, easy installation and long service life. It is widely used in various saltpeter tanks, water tanks, oil tanks, acid and alkali tanks, fusible metal melting furnaces, air heating furnaces, drying furnaces, drying boxes, hot stamping molds and other devices.
Electric heating tube is an electrical component that converts electrical energy into thermal energy. Due to its cheap price, convenient use, convenient installation, and no pollution, it is widely used in various heating occasions. At present, there are many manufacturers of electric heating components, and there are also brands of electric heating tubes. Many of them are famous, such as Shanglong and Changying. The service life of electric heating tubes is very long. Generally, the design life is more than 10,000 hours. It is more like the far infrared radiation heating element of Changying. It can have 5 heating elements. Seasonal life.

Calculation of heating value of electric heating pipe
You can use a voltage regulator to change the heat output by changing the input voltage and current.
The heat generation is proportional to the square of the voltage and proportional to the square of the current.
When the voltage becomes 1/2, the heat generation becomes 1/4
When the current becomes 1/2, the heat generation also becomes 1/4
How to verify quality electric heating pipes
The most intuitive way to verify the quality of electric heating pipes is: first wipe the surface of the electric heating pipe, then connect the AC 220V power supply, dry it in the air, and turn off the power after the surface turns red. After the electric heating pipe is completely cooled, wipe with a napkin There should be no black oxidized powder on the white paper (not reacting with oxygen in the air), indicating that it is a high-quality electric heating tube.
