Spiral duct is a commonly used duct material used for connecting and conveying airflow in air conditioning and ventilation systems. The manufacturing and production process of spiral air ducts involves multiple processes and processes. The following will provide a detailed introduction to the differences between the manufacturing and production processes of spiral air ducts.
Firstly, the manufacturing process of spiral air ducts mainly includes processes such as cutting, rolling, welding, and painting. Blanking refers to cutting the required size of the board according to design requirements, and performing preliminary leveling and deburring treatment. Roll tube is a specialized device that rolls the sheet metal obtained from cutting into a spiral shape according to a certain bending radius and angle. When rolling the duct, it is necessary to curl it according to the requirements of the duct, so that the appearance and internal structure of the spiral duct meet the design requirements.
The next step is the welding process, where spiral ducts are usually connected by welding. The joints of the spiral ducts are fixed by welding to enhance their structural strength and sealing. Welding can be done manually or mechanically to ensure welding quality and connection reliability. The seam welding of spiral air ducts is usually carried out using automatic welding equipment, which can improve production efficiency and quality. After welding is completed, it is necessary to conduct weld inspection and repair to ensure that the welding quality meets the requirements.
Then there is the painting process, and after the manufacturing of the spiral air duct is completed, it needs to undergo anti-corrosion and beautification treatment. Painting can improve the surface hardness and oxidation resistance of spiral air ducts, extending their service life. When painting, it is necessary to choose the appropriate coating according to the different environment of the air duct and carry out the painting operation.
In contrast, the production process of spiral air ducts mainly includes material procurement, design drawing, production planning, and quality control. Material procurement refers to the procurement of raw materials such as plates, welding materials, and coatings required for the manufacturing of spiral air ducts. When purchasing, it is necessary to consider the quality, specifications, and supplier credibility of the materials to ensure their quality and delivery cycle.
