详情描述

Tubes are primarily used for air circulation between two locations, serving the purpose of ventilation. Spiral ducts, made of stainless steel and galvanized iron sheet, are widely used in the market.

Helical ducts feature the following characteristics:

1. Smooth surface, free of zinc nodules and burrs, with a silvery white appearance.

2. Easy installation, with fewer connection points.

3. Low ventilation resistance and noise.

4. Good strength and rigidity.

5. Thickness is fully controllable, ranging from 5 to 107μm with any selection.

6. Free from hydrogen embrittlement and temperature damage, ensuring the material's mechanical properties remain unchanged.

7. Can replace some processes requiring hot-dipped galvanizing.

8. Excellent corrosion resistance, neutral salt spray test up to 240 hours.

9. Hot-dipped galvanized for use in environments with strong corrosive agents like various strong acids and alkaline fogs.

10. Custom-designed and made-to-order ductwork of various specifications available upon customer request.

Compared to traditionally hand-forged iron pipes, mechanically formed spiral ducts offer the following advantages:

Good sealing properties.

(2) Good strength and rigidity.

(3) Low ventilation resistance and noise, round pipes outperform square ones.

(4) Easy installation, with minimal connection points.

(5) High grade and aesthetically pleasing.
