Product Description
The most widely circulated spiral pipes in the market are galvanized sheets. The spiral duct of galvanized steel plate is basically a stainless steel spiral duct, but the price is only 2/3 or even lower than that of the stainless steel air duct. Composite spiral air duct is commonly used in places where the external environment is more common and the requirements for wind pipes are not too high.

Because iron sheets are prone to chemical reactions in various environments, they cause corrosion and rust. Zinc hardly changes in dry air. In moist air, a dense zinc carbonate film is formed on the surface of zinc. The spiral duct is mainly plated with zinc on the iron sheet of the wind pipe, which plays a protective role on the iron sheet. Zinc coating is passivated, dyed or coated with light retaining agent, which can significantly improve its protective and decorative properties.

Production workshop

The spiral duct has the following characteristics:
1, smooth appearance, no zinc tumor, burr, silver white;
2. The installation is convenient, and the connection points are few.
3. The ventilation resistance is small and the ventilation noise is small.
4, both strength and rigidity are good.
5. The thickness is controllable and can be selected within 5-107 m.
6, no hydrogen embrittlement, no temperature hazards, can ensure that the mechanical properties of materials remain unchanged.
7. It can replace the hot dip galvanizing process.
8, good corrosion resistance, neutral salt spray test for 240 hours.
9. The hot galvanizing method is applied to the strong corrosive environment such as strong acid and alkali fog.

10, according to customer requirements, specially designed and customized all kinds of duct.

Spiral duct

Compared with manual knocking of traditional white iron pipes, the mechanism of the spiral air duct has the following advantages:
(1) good seal.
(2) both strength and rigidity are good.
(3) ventilation resistance is small, ventilation noise is small, and round pipe is better than square tube.
(4) the installation is convenient and the connection points are few.
(5) high grade and beautiful appearance.
