In order to achieve good ventilation effect in large-scale buildings, ventilation measures are usually adopted. In addition to air-conditioning power equipment, some ventilation ducts are often added to achieve ventilation and ventilation function, and to achieve this goal, we are using spiral ducts and spiral ducts widely. Today we talk about Jinan Air Pipe Processing Plant:

　　尽管螺旋风管有很多,但它是在大多数情况下暴露在户外,所以风下雨,太阳,这些因素将螺旋风管侵蚀或腐蚀,因此要求它具有防腐性能的产品有镀锌螺旋风管、不锈钢螺旋风管、复合螺旋风管,三种管道耐腐蚀。

　　Although spiral duct has many advantages, it is exposed to the outdoors in most cases, so wind, rain, sun, these factors will corrode or corrode the spiral duct. Therefore, the products required for its anti-corrosion performance are galvanized spiral duct, stainless steel spiral duct, composite spiral duct, and three kinds of pipelines are corrosion-resistant.

　　螺旋风管气流良好，有效流动面积大，系统压降小，日常运行系统功耗低。同时，由于螺旋风管采用螺旋咬口，其强度高于相同规格的风管。

　　The helical duct has good air flow, large effective flow area, small pressure drop and low power consumption in daily operation. At the same time, the strength of the spiral duct is higher than that of the duct of the same specification because of the spiral bite.

　　在空气通过管道的过程中，圆周处设有螺旋咬口缝，增加了空气管道的强度，不易产生振动。因此，它在降低低频噪声的传播方面具有良好的隔声效果，可以有效地降低管壁的传声，提高建筑的质量。研究表明，由于螺旋管的刚度比螺旋管高，其下频段为3~10dB，下频段为12~ 20db。在风道截面相似、风道材料厚度相同的前提下，椭圆螺旋风道在低频段的隔声效果比矩形风道好约10dB。

　　In the process of air passing through the pipeline, there are spiral bite seams at the circumference, which increase the strength of the air pipeline and avoid vibration. Therefore, it has good sound insulation effect in reducing the transmission of low-frequency noise, can effectively reduce the sound transmission of the pipe wall, and improve the quality of the building. The results show that the stiffness of the helical tube is higher than that of the helical tube, and its lower frequency band is 3-10 dB and 12-20 db. On the premise of similar cross section and the same thickness of duct material, the sound insulation effect of elliptical helical duct in low frequency band is about 10 dB better than that of rectangular duct.

　　螺旋风管机械化程度高

　　High degree of mechanization of spiral duct

　　螺旋椭圆形风管与带钢卷螺旋风管,通过风管成型机咬骨头的形状,以及沿螺旋渐开线跟踪卷成圆管的形状,与此同时,咬缝的压力,后使用特殊设备将拉伸后的圆形风管成型加工成一个扁平的椭圆。用户可根据需要剪短。螺旋风管的制造自动化程度高，生产速度快。同时采用工厂化生产和标准化生产，大大提高了椭圆螺旋风管的生产效率，整体性强。

　　The spiral elliptical duct and the strip coiled spiral duct are formed into a flat ellipse by means of the shape of the bite bone of the duct forming machine and the shape of the coiled circular duct tracked along the spiral involute. At the same time, the pressure of the bite seam is used to shape the stretched circular duct. Users can cut it short as needed. The manufacturing automation of spiral air duct is high and the production speed is fast. At the same time, the production efficiency of elliptical helical duct has been greatly improved by adopting factory production and standardized production.
