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.

，螺旋風管的制造工藝主要包括下料、卷管、焊接和涂漆等工序。下料是指根據設計要求，將所需尺寸的板材進行切割，并進行初步的整平和去毛刺處理。卷管是將下料得到的板材按照一定的卷曲半徑和角度，通過專用設備將其卷制成螺旋狀。卷管時需要根據風管的要求進行卷曲，使得螺旋風管的外觀和內部結構達到設計要求。

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.

接下來是焊接工序，螺旋風管通常采用焊接連接，通過焊接將螺旋風管的接縫固定，增強其結構的強度和密封性。焊接可以采用手工焊接或者機械焊接，保證焊接質量和連接的可靠性。螺旋風管的接縫焊接通常采用自動焊接設備進行，可以提高生產效率和質量。焊接完成后，需要進行焊縫檢測和修補，確保焊接質量符合要求。

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.

然后是涂漆工藝，螺旋風管制造完成后需要進行防腐蝕和美化處理。涂漆可以提高螺旋風管的表面硬度和抗氧化性能，延長其使用壽命。涂漆時需要根據風管所處環境的不同選擇合適的涂料，并進行涂裝操作。

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.

相比之下，螺旋風管的生產工藝主要包括材料采購、設計制圖、生產計劃和質量控制等環節。材料采購是指采購螺旋風管制造所需的板材、焊接材料和涂料等原材料。采購時需要考慮材料的品質、規格和供應商的信譽度，確保材料的質量和交貨周期。

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.
