Spiral duct machine, is the production of spiral duct machine. Spiral ducts, also known as spiral biting thin-walled tube, first applied to the western countries of the military industry, such as warships, ship row (send) wind system, and later used for trains, subways, mines and other civilian facilities. By 2000, according to statistics, the United States office, shopping malls, subway and other applications of spiral duct has reached 95.6%, residential residential central air conditioning applications spiral duct also reached 72.5%.


Spiral duct is made of metal tape rolled into a spiral bite of the thin-walled tube, round, no welding, no leakage, no water, and more for air and bulk material delivery, instead of the traditional white iron pipe (ie manual Biting iron pipe). Is a kind of duct, the whole mechanism without straight hand beat. Its main uses are as follows:

Spiral tube

Spiral tube

1) Air supply, including ventilation, such as fresh air and exhaust, this range is very wide, such as the factory floor, the production site air, due to the need for harmful gases generated from the outdoor, but also the need for outdoor air to the room. At this time will use the flow of large and small pressure air pipeline, spiral duct is most suitable, under normal circumstances the use of galvanized iron pipe, corrosive and particularly wet places using stainless steel tube.

2) send cold air. The most common is the central air conditioning pipeline, this pipe needs to add insulation materials. Spiral duct can be posted inside the insulation material, looks beautiful appearance.

3) Exhaust smoke. Restaurants, restaurants, hotels, kitchen, a large number of fumes are produced, need to be discharged, the use of circular duct is the oil chimney. Here, the spiral duct is called the soot pipe.

4) dust removal. Some factories produce a lot of dust in the workshop, the need for special dust removal device, which the larger flow of the pipeline, you can use the spiral duct.

5) bulk material delivery. Some factories in the production process, the need to transport loose particles, especially the proportion of such as the expansion of plastic pellets like the use of spiral ducts low cost, the effect is good.

Advantages of editing

1) good product support, a high degree of standardization;

2) strong sealing;

3) ventilation loss is small; ventilation noise is small, round tube is better than square tube.

4) factory inspection convenience;

5) anti-equilibrium external pressure (negative pressure) program;

6) material province;

7) easy to install, less connection points, installation space is small, low installation costs.

8) to install the overall layout of the beautiful, high grade.

9) daily maintenance easy to clean.

10) section wet weeks small, along the resistance is small, less energy loss.

11) full mechanical processing, a molding without the need for secondary processing.

12) The use of high-speed flying cutting machine, high precision pipe diameter.

13) using shrinkage socket, casing interconnection, flange interconnection, straps connected to four ways, the installation more convenient.

14) tube insulation quality is better than rectangular air duct.
