1. The service life of the electric heating tube is very long.
2. Composition of electric heating pipe: The typical structure of metal tubular electric heating pipe is generally composed of 5 parts: insulator, sealing material, lead-out rod, filler, heating wire, metal sheath tube, and terminal. Features of electric heating tube: Electric heating tube has the characteristics of simple structure, high mechanical strength, high thermal efficiency, safety and reliability, simple and convenient installation, long service life, no pollution and so on.



3. Application of electric heating pipe: 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 stamping molds and other devices.
Fourth, the common classification of electric heating pipes: 1. According to the way of outlet, it can be divided into single-ended electric heating pipes and double-ended electric heating pipes. 2. According to the material classification, it can be divided into stainless steel electric heating tube, quartz electric heating tube, Teflon electric heating tube, titanium electric heating tube 3. According to the shape classification, it can be divided into straight electric heating tube, U-shaped electric heating tube, L-shaped electric heating tube, W-type electric heating pipe, fin electric heating pipe, special-shaped electric heating pipe 4. According to the classification, it can be divided into dry heating electric heating pipe and water heating electric heating pipe.
