Spiral ducts are classified as air ducts because they have been used for ventilation and cooling. This is the name according to its use, but it can be used in other places, even for drainage, liquid drainage or as a container, which cannot be called a duct. Named according to the structure, it should be called spiral seam thin-walled pipe, and because it is mainly made of metal, it is called spiral seam metal pipe. If it is named according to the data, it can have these names: galvanized spiral pipe, fabric air duct spiral, aluminum spiral, or in order to distinguish it from the existing fabric air duct, it can be called ultra-thin fabric air duct duct, as it can be rolled from 0.3mm or even thinner fabric duct tape. Spiral duct material is a kind of pipe made of magnesium oxychloride cement as glue and alkali glass fiber as reinforcement material, adding modifier and filling material. The main features of this type of spiral air duct are corrosion resistance, high strength, and non-combustion. In many fields, it has completely replaced the plexiglass ventilation duct. Especially in underground projects with relatively high humidity and areas south of the Yangtze River, its advantages will be stronger. For the various deficiencies such as poor resistance and brittleness of the spiral air duct, the defects of the spiral air duct can be overcome by improving the appearance function, improving the water resistance function, improving the mechanical function and other methods, which is a new trend in the development of the spiral air duct in the future . The traditional air duct requires the construction of the thermal insulation layer on site, so it needs a certain construction height, which puts forward additional requirements for the height of the building. The spiral air duct does not require on-site insulation construction, so there is no need to reserve construction space, which can reduce the height of the building. Spiral ducts are available in a variety of colors, are beautiful, and are particularly suitable for surface installation. The appearance of the traditional air duct needs to be wrapped with aluminum foil on site, so the surface installation effect is not very good. Spiral ducts can be widely used in industrial and civil buildings, hotels, hospitals, office buildings and other places with special needs. Due to the small wind resistance, light weight, and simple and convenient installation of spiral air ducts, in foreign countries, a large number of circular air ducts, namely spiral air ducts, are used in ventilation ducts. 50%. In China, rectangular air ducts are still widely used. Experts predict that the domestic spiral air duct market is huge and has a lot of room for development. The domestic construction machinery industry has been affected to varying degrees. However, the Chinese government subsequently issued ten investment measures and a 4 trillion yuan investment plan, which once again showed the government's determination to promote economic growth by increasing investment, which is beneficial to the domestic construction machinery industry. need. At present, the flat oval air duct can also be used to reduce the height of the occupied space of the air duct. The flat oval air duct is a spiral air duct that is processed into a flat oval shape by stretching and shaping the spiral air duct. Since the two sides of the air duct are round, the airflow is stable, the rigidity of the air duct is good, and the exposed installation is beautiful. It is an ideal air duct series. In addition, the total cost of the spiral air duct is lower due to the less support and hanger required and less installation workload. Because the four corners of the rectangular air duct are prone to turbulence, which reduces the effective flow area, the spiral air duct has good air mobility and large effective flow area, so the secondary noise of the spiral air duct is small. Therefore, the low-frequency noise caused by the vibration of the air duct is smaller, the air flow performance is good, the system pressure drop is small, and the daily operation system consumes less power.
