这大大降低了生产成本。另外，需要告诉我们的是，螺旋风管的制造工艺是非常精密的。它一般是用特种钢制成的，质量自然有保证，可以使用几年。共同作用还能保证长时间使用不变形，大大延长了风管的使用寿命，对我们的生产具有重要的现实意义。

This greatly reduces production costs. Additionally, it should be noted that the manufacturing process of spiral air ducts is very precise. It is usually made of special steel, with guaranteed quality and can be used for several years. The joint effect can also ensure long-term use without deformation, greatly extending the service life of the air duct, which has important practical significance for our production.

螺旋风管的制造是选用带钢带卷，用风管成型机一次性咬出咬骨形状，沿螺旋渐开线轨迹滚成圆管状，并将咬缝压在一起，后按要求长度切割而成。自投放市场以来，因其性能优异、运行成本低，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。

The manufacturing of spiral air ducts involves using a steel strip coil, using a duct forming machine to bite out the bite bone shape in one go, rolling it into a circular tube shape along the spiral involute trajectory, pressing the bite seams together, and then cutting it to the required length. Since its launch in the market, it has been widely used in shipbuilding, ventilation, air conditioning, purification, bridge dust removal, airports, tunnels and other construction industries due to its excellent performance and low operating costs.

送冷风和送热风常见的方式是空调的管道，需要保温。还可在内部粘贴保温材料，使风管具有美观的螺旋状外观，并可避免吊顶，降低工程造价。螺旋风管的制造自动化程度高，生产速度非常快。一般风管每分钟可产生20～40米，是由于其原材料镀锌带钢低于整体镀锌钢板，其工厂化生产和标准标准化使成本低于矩形风管。

The common way to supply cold air and hot air is through the pipes of central air conditioning, which require insulation. Insulation materials can also be pasted inside to give the air duct a beautiful spiral appearance and avoid suspended ceilings, reducing project costs. The manufacturing automation of spiral air ducts is high, and the production speed is very fast. Generally, air ducts can produce 20-40 meters per minute due to the lower price of galvanized strip steel as its raw material compared to overall galvanized steel plates. Its factory production and standardization result in lower costs than rectangular air ducts.

螺旋风管选用技术设备后，如果配备与其他工序相对应的加工设备，各工序空调风管的加工进度和质量都会有较大提升，但加工工艺仍为多工序分离加工，仍需大量人力在多台设备上旋转，空调风管的加工规划、加工力和质量仍停留在较低阶段。可喜的是，选用普通板式法兰连接技术后，空调风管的加工工序不仅少了，还省去了许多人工操作工序，仍需下料、切角、压筋、普通板式法兰成型、咬角缝、组装等工序。

After selecting advanced technology equipment for spiral air ducts, if equipped with processing equipment corresponding to other processes, the processing progress and quality of air conditioning ducts in each process will be greatly improved. However, the processing technology is still separated from multiple processes and requires a lot of manpower to rotate on multiple devices. The processing planning, processing force, and quality of air conditioning ducts are still at a relatively low stage. Fortunately, with the use of ordinary plate flange connection technology, the processing procedures for air conditioning ducts have not only been reduced, but also many manual operations have been eliminated. There are still processes such as cutting, cutting corners, pressing reinforcement, forming ordinary plate flanges, biting corner seams, and assembly.

接头为周向，接头强度远高于径向直接头，所以在1.5倍工作压力下能保证接头处无裂纹，因为其原材料镀锌带钢低于整片镀锌钢板，其工厂化生产和标准标准化使成本低于矩形风管;另外，由于其支吊架需求量小，安装工作量小，所以总成本低。由于矩形风管四角易发生湍流，有用流动面积减小，空气流动性好，有用流动面积大，产品的二次噪声因强度大而小。因此，风管振动引起的低频噪声更小，空气流动性能好，系统压降小，日常运行系统耗电少。

The joint is circumferential, and the strength of the joint is much higher than that of the radial joint. Therefore, it can ensure that there are no cracks at the joint under 1.5 times the working pressure, because the raw material of galvanized strip steel is lower than the entire galvanized steel plate. Its factory production and standardization make the cost lower than rectangular air ducts; In addition, due to the small demand for its supports and hangers and the small installation workload, the total cost is low. Due to the susceptibility of turbulence at the four corners of rectangular air ducts, the useful flow area is reduced, the air flow is good, the useful flow area is large, and the secondary noise of the product is reduced due to its high intensity. Therefore, the low-frequency noise caused by duct vibration is smaller, the air flow performance is good, the system pressure drop is small, and the daily operation of the system consumes less power.
