Silicon Carbide Radiant Tube
- [Introduction]: The reaction sintered silicon carbide radiant tube has high-temperature resistance, corrosion resistance, oxidation resistance and long service life, which can replace imported products. A complete set of heat exchangers includes five parts: flame tube, inner tube, radiant tube, connector, and outer tube. At present, we can also formulate a more suitable size assembly plan according to the customer’s specific kiln shape, using temperature and other different use conditions to achieve the most ideal energy-saving effect.

- Advantages
- We can provide a variety of installation solutions for silicon carbide radiant tubes according to the customer's use environment.
- Under extremely cold and extremely hot conditions, the product performance is stable.
- The use of silicon carbide radiant tubes can save energy.
- Compared with metal materials, silicon carbide radiant tubes have higher thermal conductivity and better thermal stability.
- Product Application
Silicon carbide radiant tube is widely used in tunnel kilns, shuttle kilns, roller kilns and other gas and oil-fired industrial furnaces. It can also be used in the push-fire treatment production line of industrial kilns in iron and steel, metallurgy and other industries.
- Our Packing
The two packing methods we use are plywood box packing and solid wood packing, with the solid wood box requires a fumigation certificate. Depending on the various products, we will tailor the proper packaging box; Plastic foam measuring 2 cm to 3 cm thick is placed within the box and secured with row nails. To maintain the products safety during shipment, packing tape is typically used.
