Radiator electric heating pipe

1. It is fixed by threaded screws. The general specifications are: the bottom is equipped with a type tube and a thermocouple, and an external thermostat and leakage protection plug can be installed. The power can be:,,, or customized according to customer needs. Yancheng Ruigao Electric Heating Equipment Co., Ltd. specializes in the production of electric heating tubes for radiators, with high quality and low price. Customers are welcome to purchase, and large quantities will be favored.
2. The basic structure of the electric heating tube
It uses a metal tube as the outer shell, and spiral electric heating alloy wires (nickel-chromium, iron-chromium alloy) are evenly distributed along the central axis of the tube. The gaps are filled and compacted to have good insulation and thermal conductivity. High-performance magnesia sand, with both ends of the tube mouth sealed with silica gel or ceramics. This metal-armored electric heating element can heat air, metal molds and various liquids.
According to the different usage status, safety and installation needs of the electric heating pipe of the radiator, the electric heating pipe will also include other structures such as sealing structure, terminal part structure, flange, temperature control or fuse.
3. Performance:
Stainless steel electric heating tube is an electric heating element placed in a metal tube, and the gap is closely filled with crystalline magnesium oxide powder with good heat resistance, thermal conductivity and insulation. Processed by other processes. 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-base tanks, fusible metal melting furnaces, air heating furnaces, drying furnaces, drying boxes, hot pressing molds and other devices.
4. Precautions for the use of radiator electric heating tubes
The components should be stored in a dry place. If the insulation resistance drops below megohms due to long-term storage, it can be dried in an oven at about ℃ for several hours. (Or pass the component under low voltage for several hours), that is, the insulation resistance may be restored.
When it is found that there is carbon on the surface of the tube, it must be removed before use to avoid reducing efficiency or even burning out the components.
When melting solid oils such as asphalt and paraffin, the voltage should be reduced and then raised to the rated voltage after melting. To prevent the concentration of power from reducing the service life of components.
