The use of spiral duct

The spiral air duct is a thin-walled pipe made of a spiral bite made of metal strips. It is round, without welding, air leakage and water leakage. It is mostly used for air supply and bulk material transportation, instead of traditional white iron pipes (ie manual bite iron pipe). It is a kind of air duct, the whole mechanism, the straight pipe does not need to be beat by hand. Its main uses are as follows: (1) Air supply, including ventilation, such as supplying fresh air and exhausting, this range is very wide, such as factory workshop, production site air, due to the generation of harmful gases, it needs to be discharged outdoors, and it is necessary to transport outdoor air to indoors . At this time, it is necessary to use air conveying pipes with large flow and low pressure. Spiral air pipes are the most suitable. Generally, galvanized iron pipes are used, and fabric air pipes are used in corrosive and particularly humid places. (2) Send cold air. The most common is the pipeline of the central air conditioner, which requires insulation materials. The spiral air duct can be pasted with thermal insulation material, and the appearance looks beautiful. (3) Exhaust oil fume. The kitchens of restaurants, restaurants, and guesthouses produce a lot of oil fumes, which need to be discharged. The use of circular air ducts is the oil chimney. Here, the spiral duct should be called a fume duct. (4) Dust removal. In some factories, there is a lot of dust in the production workshop, and special dust removal devices are required. Among them, spiral air ducts can be used for pipes with large air flow. (5) Bulk material conveying. In the production process of some factories, it is necessary to transport loose particles, especially the use of spiral air ducts with low specific gravity such as foamed plastic particles, which has low cost and good effect.

Many of us have heard about resistance temperature detector and seen some of these units in operation in temperature sensor manufacturers, RTD supplier and temperature sensor manufacturers spaces.
