Spiral duct use
Spiral duct is made of metal strip rolled into a spiral bite wall of the thin 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:
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.
