螺旋风管的接缝是周向的，接缝的强度比径向的直缝强度要高许多，所以能保证在1.5倍工作压力下接缝处无裂开，由于其原材料镀锌带钢与整张镀锌钢板相比，较低，加上其工厂化生产和规格的标准化，使得造价要比矩形风管低；另外由于其支、吊架需量少，安装工作量少，所以总成本较低。

The joint of spiral air duct is circumferential, and the strength of the joint is much higher than that of radial straight joint, so it can ensure that there is no crack at the joint under 1.5 times the working pressure. Due to the low price of its raw material galvanized steel strip compared with the whole galvanized steel plate, and its industrialized production and standardization of specifications, the cost is lower than that of rectangular air duct; In addition, the total cost is low due to less demand for supports and hangers and less installation workload.

由于矩形风管的四角易产生湍流，减少了通流面积，空气流动性好，通流面积大，所以产品的二次噪声小，由于其强度大。因此风管振动引起的低频噪声小，空气流动性能好，系统压降小，日常运行系统耗电量少。

Because the four corners of the rectangular air duct are easy to produce turbulence, the flow area is reduced, the air fluidity is good, and the flow area is large, so the secondary noise of the product is small, and its intensity is large. Therefore, the low-frequency noise caused by air duct vibration is small, the air flow performance is good, the system pressure drop is small, and the power consumption of the daily operation system is small.

螺旋风管压制楞筋工艺精巧，让螺旋风管能够承受强压力，咬口潜缝厚度是管体的四倍，管道的刚性非常大，显示出坚固的优越性，能承受大的压力负荷而无损变形，用材厚度可减小百分之15。这样就大大降低了生产的成本。另外，我们需要告诉大家的是济南通风管道加工的制作工艺是非常精的，它一般都是采用特种钢制作而成的，因此它的质量自然有保证，一般可以使用上好几年的时间，同时他还能保证长期使用，这样大大延长了风管的使用寿命，对于我们的生产来说有着重要的现实意义。

The spiral air duct has exquisite process of pressing ribs, so that the spiral air duct can withstand strong pressure. The thickness of the undercut hidden seam is four times that of the pipe body. The rigidity of the pipe is very large, showing the advantages of firmness. It can withstand large pressure load without deformation, and the thickness of materials can be reduced by 15%. This greatly reduces the cost of production. In addition, we need to tell you that the manufacturing process of Jinan ventilation pipe is very precise. It is generally made of special steel, so its quality is naturally guaranteed. It can be used for several years. At the same time, it can also ensure long-term use, which greatly prolongs the service life of the air pipe, It has important practical significance for our production.

螺旋风管的制作是采用带钢带状卷料，通过风管成型机一次咬出咬口骨形，并沿螺旋渐开线轨迹卷成圆形管状，同时将咬口缝压紧，后按需要的长度切割而成。自投放市场以来，因其本身性能及低廉的动作成本，被广泛应用于造船、通风、空调、净化、桥梁除尘、机场、隧道等建筑行业。送冷风和热风常见的是空调的管道，这种管道需要加保温材料。也可内贴保温材料，使风道具有螺旋形的漂亮外观，可免吊顶，从而降低了工程造价。

The spiral air duct is made of strip steel coil, which bites out the bite bone shape at one time through the air duct forming machine, rolls it into a circular tube along the spiral involute track, compresses the bite seam at the same time, and then cuts it according to the required length. Since it was put on the market, it has been widely used in shipbuilding, ventilation, air conditioning, purification, bridge dust removal, airport, tunnel and other construction industries because of its own performance and low operation cost. Air conditioning pipes are commonly used to supply cold air and hot air, which need thermal insulation materials. Thermal insulation materials can also be pasted inside, so that the air duct has a beautiful spiral appearance, and the ceiling can be avoided, so as to reduce the project cost.

螺旋风管的制造高度自动化，生产速度很快，一般的风管每分钟能生产20～40米，由于其原材料镀锌带钢与整张镀锌钢板相比，较低，加上其工厂化生产和规格的标准化，使得造价要比矩形风管低。

The manufacturing of spiral air duct is highly automated and the production speed is very fast. The general air duct can produce 20 ~ 40m per minute. Due to the low price of its raw material galvanized steel strip compared with the whole galvanized steel plate, coupled with its industrialized production and standardization of specifications, the cost is lower than that of rectangular air duct.
