Product Description

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.

Production workshop

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.
Main advantages

The installation of the spiral duct significantly reduces the connection point between the tube and the tube to minimize the leakage of the pipe joint, the typical length of the spiral duct is 3~6m, and the typical rectangular wind pipe is only 1~1.5m in length, and only one pipe connector is connected to the two spiral wind pipes, while the traditional rectangular wind pipe is often connected. A completely independent double flanged system is needed.

Spiral duct

1. Standardized products
The production of fittings (fittings and fittings) of spiral air ducts has been highly automated and systematic, and has industrialized quality control.
2. Low installation cost
The installation time of the circular duct system is only 1/3 similar to that of the rectangular pipe.
3. Usually only a small installation space is needed

Without increasing any pressure drop, a circular pipe with a diameter of 200mm can be replaced by a 250 * 150mm rectangular pipe in the same installation space. Without additional installation space, several parallel circular pipes can replace flat rectangular pipes. Considering all the factors, in most cases, the space occupied by a circular pipe is less than that of a rectangular pipe. For the same pressure characteristics, the installation space of several circular pipes is often the same or less than the installation space of a rectangular pipe. Many rectangular pipe systems need 4 bolt systems when installing, thus increasing 40~80mm in all directions of the pipeline.

90 degree elbow

4, pressure reduction: the wind resistance of the circular duct is much smaller than that of the rectangular duct.
5, the precise bite forming process: the mould used by the imported equipment is the special steel structure. Even if it is used for 35 years, the surface of the pressing die remains unchanged, which makes the surface of the galvanized steel plate not damaged, greatly prolongs the service life of the wind pipe, and the joint is uniform and smooth, the bite is tight, and the connecting force is strong. Good seal.
6. Safety sealing ring leakage prevention system
7, the exquisite spiral crenching rib technology makes the spiral pipe with the best strength to bear pressure. After increasing the spiral type, the thickness of the bite seam is four times that of the tube body. The rigidity of the pipe is very large, which shows the strong superiority, can withstand the maximum pressure load without damage, and the thickness of the material can be reduced by 15% and the cost is reduced. .
8. In the same section, the circumference of the rectangular wind pipe with the ratio of length and width to 1:3 is 40% longer than that of the spiral duct, and the material can be saved. For the same reason, the heat insulation material can be reduced accordingly as the circumference of the spiral pipe is short.
9, pipeline layout beautiful, strong sense of three-dimensional: when the pipeline as a building feature must be exposed, elegant and elegant flange pipe will be the best choice.
10. The installation form of the socket type spiral circular wind pipe.
