In the field of ventilation ducts, products such as rectangular air ducts and galvanized air ducts are widely used due to their excellent performance. However, when faced with many materials, diverse specifications, and complicated processes, how to choose the right product often causes confusion among purchasers.

Product materials and customization

What determines the service life and application scenarios of the air duct is its material. The common galvanized steel plate has low cost and good anti-rust performance. It is suitable for most ventilation environments. Shaanxi Yan'an angle steel flange air duct manufacturer direct sales angle iron flange rectangular spiral duct central air conditioning tinplate ventilation duct galvanized air duct. In chemical plants, laboratories or coastal areas with high humidity, strong acid and alkali mist will cause The ordinary galvanized layer will corrode, so stainless steel must be used at this time. Although the initial investment of stainless steel air ducts is high, its excellent corrosion resistance can reduce replacement and maintenance costs in the long run. The market can provide plates with various thicknesses from 0.5 mm to 1.2 mm. Users should choose the appropriate thickness according to the pipe size and system pressure requirements.

Specification design and production

The design of ventilation systems in modern buildings and industrial projects is quite complex, and there are almost no completely uniform standard dimensions. Therefore, on-demand customization has become the norm in the industry. Professional manufacturers can accurately produce pipes of required length, diameter and connection form based on the drawings or technical requirements provided by customers. This flexibility ensures that the air duct can perfectly fit the building structure, reduces the trouble of on-site modifications, and eliminates material waste, which plays a positive role in controlling the total project cost.

Core performance features

A high-quality air duct must first have a smooth and flat appearance, with no burrs or burrs. This is not only a matter of appearance, but also a matter of airflow efficiency and ease of cleaning. The air duct with a smooth internal surface can significantly reduce the resistance generated by air flow . Central air conditioning ventilation ducts (white iron/galvanized sheet) are riveted and welded , thereby reducing fan energy consumption and operating noise. The pipes treated by the hot-dip galvanizing process have a very strong coating and a strong combination with the steel plate. The overall strength and rigidity are quite excellent and can withstand a certain amount of external pressure. They are not easily deformed during installation and long-term use, ensuring the airtightness and stability of the system.

Angle iron flange process advantages

Originally, angle iron flange ducts would be produced using mechanization, and then the steel strips would be spirally seamed into the desired shape. Under this process, the pipes do not need to be welded, which blocks the hidden dangers of air leakage and water leakage from the root. Compared with traditional hand-made tin pipes, full-machine production ensures uniform product quality. Straight pipe sections do not need to be hammered on site, and engineering efficiency is greatly improved. Its air tightness is very good due to riveting and welding of central air conditioning ventilation ducts (white iron/galvanized sheet) , and its advantages are very significant in systems such as central air conditioning that have strict requirements for air leakage rates.

Cost and efficiency analysis

From the overall project perspective, the use of formed angle iron flange ducts can save a lot of hidden costs. It reduces the investment in equipment required for on-site production, reduces the number of professional workers, and reduces the area of ​​the processing site. The bolt connection method simplifies the installation process and shortens the construction period. Because the product has good anti-rust properties and high strength, its service life is extended and subsequent maintenance costs are also reduced. In addition, factory prefabrication avoids noise and dust pollution caused by on-site cutting and welding, which is more in line with the environmental protection requirements of modern construction sites.

Wide range of application scenarios

This type of air duct is found in almost every field that requires air treatment. In the central air conditioning system of commercial buildings , the central air conditioning ventilation duct (white iron/galvanized sheet) is riveted and welded . It is responsible for transporting hot and cold air. In the factory workshop, it is used to discharge harmful gases and transport fresh air. Fresh air is used to ensure production safety. In hotel kitchens, it serves as an efficient oil fume emission pipe. In environmental protection and fire protection systems, it is a key component for dust removal and smoke exhaust. Its strong characteristics can also enable it to be used to transport certain lightweight bulk materials, achieving a multi-purpose effect in one pipe.
