How to distinguish between heating tubes and electric heating radiant tubes?

Heating tube:
Electric heating tube (electric heating tube) is made of metal tube, which is used as an external high resistance electric heating alloy wire as a heating material. It is filled and compacted around the electric heating wire, and has good insulation performance. High thermal conductivity and high purity magnesium oxide are used as fillers, as well as the inherent power of the product. Large, high thermal efficiency, fast heat dissipation, and other characteristics. It is commonly used in plastic packaging, small mold heating, analytical instruments, cigarette industry, shoemaking industry, semiconductor eutectic welding, die-casting input channel heating, no casting injection, and various gas expansion refrigeration effects.
Electric heating radiant tube:
Electric heating radiant tubes are tubes that extend in a straight line from the center in all directions. Refers to the transportation of supervisory materials to non central pipelines (or main pipelines) at designated or unspecified addresses. Heat pipes are usually made of gaseous fuel, which is made of heat-resistant steel by casting or welding. Radiant tubes come in various shapes, including U-shaped, W-shaped, and triangular shapes. The most commonly used radiant tube is a U-shaped radiant tube, with a fuel nozzle at one end and an injector at the other end. Burning products.
How to distinguish between heating tubes and electric heating radiant tubes?
Electric heating radiant tubes transfer heat through radiant light/electric heating tubes, and can transfer heat in various media. The heating medium is air: the efficiency of radiant tubes is higher than that of electric heating tubes. The service life of the radiant tube is lower than that of the electric heating tube.
Radiant tube heating elements, high, medium, and low temperature furnaces, as well as special atmosphere furnace specifications are optional. The shell is made of seamless high-temperature alloy pipes, coils, centrifugal cast pipes, and non-metallic special carburized sleeves. And depending on the heating element of the radiant tube under various atmospheres and harsh cycling conditions, the general resistance of the alloy cannot be used. The company's researchers have developed a special material for a new type of resistance alloy radiant tube. This material has stable performance, high resistivity, and low temperature coefficient, making it suitable for various radiant tube heating elements and replacing expensive imported materials.
The low-temperature radiant tube heating element is used for the heating element of the drying furnace device. Compared with ordinary electric heating elements, its advantages are as follows:
1. Easy to install, test, and maintain, all outside the furnace. There is no need to stop the furnace or cool down the furnace temperature to maintain and replace the electric heating unit. Under normal production conditions, replacement only takes about 10 minutes, greatly reducing labor intensity and improving production efficiency.
2. Compact structure, stable performance, single power supply, and service life several times that of ordinary electric heating tubes. Therefore, it is an ideal new product for tunnel kilns.
