Spiral duct ventilation duct is a ventilation system used in buildings, industrial plants and public facilities.

Compared with the traditional rectangular pipe, the advantages of spiral pipe ventilation pipe are its compact structure, low fluid resistance, low noise, strong corrosion resistance and so on.

This paper will introduce the basic principle, characteristics and application of spiral pipe ventilation pipe.

First, basic principles

Spiral pipe ventilation pipe is made of a number of spiral metal sheet coil, its cross-section is circular or semi-circular, usually using hot dip zinc treatment to improve its corrosion resistance.

In the production process of spiral pipe ventilation pipe, it is necessary to cut the metal sheet into a certain size sheet, and then roll it into a certain diameter pipe by crimping machine.

After the winding is completed, the pipeline needs to be welded, bent and other processing to meet the needs of different occasions.

Ii. Characteristics

1. Compact structure:The wall thickness of the spiral pipe ventilation pipe is thinner, and the cross-sectional area is smaller than that of the traditional rectangular pipe, which can save building space and facilitate installation and maintenance.

2. Small fluid resistance:the inner wall of the spiral pipe ventilation pipe is smooth, and the friction resistance of the fluid in the pipe is small, which can improve the air volume and reduce the fan operation power, thereby saving energy consumption.

3. Low noise:The inner wall of the spiral pipe ventilation pipe is smooth, and the air flow through the pipe will not produce obvious noise, which can improve the comfort of the indoor environment.

4. Strong corrosion resistance:spiral pipe ventilation pipe adopts hot dip zinc treatment, which can increase its corrosion resistance and avoid pipe rust and corrosion.

5. High reliability:In the production process of spiral pipe ventilation pipe, automatic production line is used, which has stable production, high production precision and reliable pipeline quality.

3. Application fields

Spiral pipe ventilation pipe can be widely used in industrial plants, commercial buildings, hospitals, schools, gymnasiums, underground garages and other occasions, can be used for air conditioning, ventilation, exhaust smoke and so on.

In the industrial field, spiral pipe ventilation pipes are often used in the ventilation system of chemical plants, power plants, steel plants, paper mills and other enterprises, which can effectively improve the comfort and safety of the production environment.

In short, the spiral pipe ventilation pipe has many advantages in the ventilation system, which can improve the efficiency of the system, reduce energy consumption, improve the indoor environment and other problems.

In the future, with the continuous development of industrialization and urbanization, the application range of spiral pipe ventilation pipes will be more and more extensive.
