螺旋风管是用金属带卷制作螺旋状咬合的薄管，圆形无焊接，多用于送风和新风气流输送，取代过去的白铁管(即人工咬合铁管)是通风管之一。
Spiral air duct is a thin pipe made of metal strip coils with spiral bite, circular and non welded shape. It is mostly used for air supply and fresh air flow transportation, replacing the previous white iron pipe (i.e. manual bite iron pipe) as one of the ventilation pipes.
种类、全功能、圆形管道无需人工敲击，螺旋风管道的安装程序明显减少了管道与管道的连接点，将螺旋风管道连接部分的泄漏减少到小程度，是一般的螺旋风。
The type, full function, circular pipeline does not require manual tapping, and the installation program of the spiral air pipeline significantly reduces the connection points between the pipeline and the pipeline, reducing the leakage of the connection part of the spiral air pipeline to a small extent, which is a typical spiral air pipeline.
通风管道加工长度为3~6m，而普通方形通风管道长度仅为1~1.5m；连接两个螺旋风管道只需要一个管接头，而过去矩形通风管道的连接往往需要一个立式双法兰系统。
The processing length of ventilation ducts is 3-6m, while the length of ordinary square ventilation ducts is only 1-1.5m; Connecting two spiral air ducts only requires one pipe joint, while in the past, the connection of rectangular ventilation ducts often required a vertical double flange system.
不锈钢济南通风管道加工可分为圆形和矩形。可根据工程现场的不同要求生产各种形状、规格型号和板材的成品通风管道。成品不锈钢管道具有优异的耐腐蚀性、耐热性、高强度等物化性能，通风管道主要应用于各种气密性要求高的工艺排气系统、溶剂排气系统、有机排气系统、废气排气系统和普通排气系统的室外部分、湿热排气系统、排气除尘系统等。
The processing of stainless steel Jinan ventilation ducts can be divided into circular and rectangular shapes. We can produce finished ventilation ducts of various shapes, specifications, models, and plates according to the different requirements of the engineering site. Finished stainless steel pipes have excellent physical and chemical properties such as corrosion resistance, heat resistance, and high strength. Ventilation pipes are mainly used in various process exhaust systems with high airtightness requirements, solvent exhaust systems, organic exhaust systems, exhaust gas exhaust systems, and outdoor parts of ordinary exhaust systems, wet and hot exhaust systems, exhaust dust removal systems, etc.

Ventilation pipeline processing
精密咬合成型工艺：大型设备选用的模具均为特殊钢结构。即使使用五年，压制模具的表面仍保持不变，使镀锌铁皮的表面不受损坏。损伤大大延长了通风管的使用周期。此外，板缝光滑，咬合紧密，连接力强，密封性能好。
Precision bite forming process: The molds used for large equipment are all of special steel structures. Even after five years of safe use, the surface of the pressing mold remains unchanged, ensuring that the surface of the galvanized iron sheet is not damaged. The damage greatly prolongs the service life of the ventilation pipe. In addition, the board seam is smooth, tightly occluded, with strong connection force and good sealing performance.
精巧的螺旋压制钢筋加工技术使螺旋风管道具有承受压力的强度，增加螺旋型钢筋后，咬口潜缝板厚度是管体的4倍，管道钢度大，显示出坚固的特殊性能够承受较大的压力负荷不损坏变形，材料板的厚度可以降低15%，节约成本。
The exquisite spiral pressing steel bar processing technology endows the spiral air duct with excellent strength to withstand pressure. With the addition of spiral steel bars, the thickness of the bite seam plate is four times that of the pipe body, and the pipeline has a high degree of rigidity, demonstrating its sturdy and special ability to withstand large pressure loads without damage or deformation. The thickness of the material plate can be reduced by 15%, saving costs.
