Usefulness of canning equipment HVAC equipment! Spiral duct is a thin-walled tube made of metal strip coils with a spiral seam. It is round, without welding, air-tight, and water-tight. It is mostly used for air supply and bulk material transportation. , Instead of the traditional white iron pipe (that is, manual sewn iron pipe). It is a kind of wind pipe, full mechanism, straight pipe without manual beating. Its important uses are as follows:

(1) Air supply includes ventilation, such as fresh air supply and exhaust air. This scale is very wide, such as factory workshops and production site air. Because harmful gases are generated, they need to be discharged outdoors and outdoor air needs to be delivered indoors. At this time, it is necessary to use air conveying pipes with large flow and low pressure. Spiral ducts are the most practical. Under normal conditions, galvanized iron pipes are used, and stainless steel pipes are used for corrosive and particularly humid occasions.

(2) Canning equipment Send cold wind. The most common is the ducts of central air conditioners, which require insulation. The spiral duct can be pasted with thermal insulation material, and the appearance looks elegant.

(3) Exhaust oil fume. A large amount of oil fume is generated in restaurants, restaurants, and hotel kitchens, which need to be discharged. The circular air duct is the oil chimney. Here, the spiral duct should be called the lampblack duct.

(4) Dust removal of canning equipment. In some factories, there is a lot of dust in the production workshops, and special dust removal devices are required. Among them, spiral ducts can be used for pipes with large air flow.

(5) Bulk material transportation of canning equipment. In the production process of some factories, it is necessary to transport loose particles, especially the application of spiral ducts such as foamed plastic particles with a small proportion, with low cost and good effect.
