详情描述

The pipe is mainly used for air circulation between two places, 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, appearing silvery white.

2. Easy installation, minimal connection points.

3. Low air resistance and low ventilation noise.

4. Good strength and rigidity.

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

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

7. Can replace part of the hot-dip galvanizing process.

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

9. Hot-dip galvanized for use in environments with strong corrosive agents such as various strong acids, alkali fumes, etc.

10. Custom-designed and made-to-order ductwork of various specifications available upon customer's 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 are superior to rectangular pipes.

(4) Easy installation, minimal connection points.

(5) High quality and aesthetically pleasing.
