How do you install an electric heating radiant tube?
1. Electricity Radiation tube The rigidity at both ends cannot be fixed, to prevent the radiation heating tube from being crushed due to adverse external forces from mechanical equipment.
2. The porcelain sockets at both ends of the electric radiation tube and the corresponding parts of the mechanical equipment should be matched as flexibly as possible, with radial and peripheral clearances no less than 1 to 3 mm. If a ductile clamp is used, it is also necessary to ensure that there is sufficient thermal deformation space between the tube body and the rigid component.
3. In ultra-low-temperature zones below standard, porcelain heads can be placed at both ends of the radiation heating tube to extend its service life.
4. When in use, heating radiation tubes should generally be kept essentially horizontal; if they are used individually, they need to be installed at an angle or vertically.
5. In general, radiation heating tubes should be kept essentially horizontal during use; if they are used individually, they need to be installed at an angle or vertically.
6. For radiation heating tubes coated with a golden reflective layer, during the entire installation and use process, please avoid scratching the reflective layer with hard objects.
7. When installing the power supply cable for the infrared radiation heating tube, please wear heat-resistant, insulating porcelain waterproof sleeves or fiberglass tubes to prevent potential hazards in case of power failure.
8. To minimize inconvenience to customers throughout the installation process, it is recommended to opt for indoor renovation.

9. Infrared radiation heating tubes and electric heaters can be combined with auxiliary equipment such as temperature controllers, thyristor power regulators, and AC voltage regulators to form a fully automatic temperature control system. Since infrared radiation heating tubes have a high inrush current (with a short delay time) when starting up under thermal conditions, this characteristic must be taken into account when selecting temperature control devices. It is recommended to use dedicated thyristor-based intelligent power regulators and AC voltage regulators as part of the supporting control system.
Electrothermal effect Radiation tube What are the factors of quality?
Among the factors affecting the quality of stainless steel electric heating tubes, material quality is the most critical factor. The rational selection of raw materials for electric heating tubes is a prerequisite for ensuring their quality. The following points can serve as references when choosing materials:
1. Pipe selection criteria: temperature resistance and corrosion resistance. Radiation pipe
2. Selection of resistance wire.
3. Selection of magnesium oxide powder.
4. Selection of sealing materials. Radiation tube
First, the stainless steel material 301, after undergoing hardening treatment when deformed during processing, is suitable for a variety of high-strength applications. In the manufacturing of stainless steel heating tubes, the stainless steel material 304 is widely used for heating liquids (excluding strong acids and strong bases) and air. It boasts excellent overall performance, is easy to form, and has a moderate price, making it widely employed in the production of heating tubes.
Stainless steel 302 is actually a grade with a higher carbon content than 304; after cold rolling, it exhibits greater strength. Stainless steel grade 303, due to its sulfur content, is easy to machine and is primarily used in applications where ease of machining and high surface finish are required.
That’s all for today’s explanation. Thank you for watching, and we’ll see you next time!
