The spiral air duct has exquisite reinforcement limiting technology to make the spiral air duct accept strong pressure. The thickness of the submerged joint at the undercut is four times the thickness of the pipe body. The rigidity of the pipe is very large, showing the superiority of firmness. It can accept large pressure load without damage and deformation, and the thickness of the material can be reduced by 15%.

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。

Which greatly reduces the production cost. In addition, we need to know that the manufacturing process of spiral air duct is very precise. It is generally made of special steel, and the quality is naturally guaranteed. It can be used for several years. The joint action 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 spiral air duct is manufactured by selecting the steel strip roll, biting the bone shape with the air duct forming machine at one time, rolling it into a circular tube along the spiral involute track, pressing the biting seam together, and then cutting it according to the required length. Since it was put on the market, because of its excellent performance and low operating cost, it has been widely used in shipbuilding, ventilation, air conditioning, purification, bridge dust removal, airport, tunnel and other construction industries.

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 the pipe of central air conditioner, which needs insulation. Thermal insulation materials can also be pasted inside to make the air duct have a beautiful spiral appearance, avoid the ceiling, and reduce the project cost. The manufacturing automation of spiral air duct is high and the production speed is very fast. The general air duct can produce 20-40m per minute, because the price of its raw material galvanized steel strip is lower than that of the whole galvanized steel plate, and its factory production and standardization make the cost lower than that of the rectangular air duct.

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 the spiral air duct is equipped with advanced technology and equipment, if the processing equipment corresponding to other processes is provided, the processing progress and quality of the air-conditioning air duct in each process will be greatly improved. However, the processing process is still multi process separation processing, which still requires a large number of manpower to rotate on multiple equipment. The processing planning, processing force and quality of the air-conditioning air duct are still at a low stage. It is gratifying that after the common plate flange connection technology is selected, the processing procedures of the air duct of the air conditioner are not only reduced, but also many manual operation procedures are saved, such as blanking, corner cutting, rib pressing, common plate flange forming, corner biting seam 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 direct head. Therefore, it can be ensured that there is no crack at the joint under 1.5 times the working pressure. Because the raw material galvanized steel strip is lower than the whole galvanized steel sheet, its factory production and standardization make the cost lower than that of the rectangular air duct; In addition, the total cost is low due to the small demand for supports and hangers and the small installation workload. As the four corners of the rectangular air duct are prone to turbulence, the useful flow area is reduced, the air fluidity is good, the useful flow area is large, and the secondary noise of the product is small due to the high intensity. Therefore, the low-frequency noise caused by the air duct vibration is smaller, the air flow performance is good, the system pressure drop is small, and the daily operation system consumes less power.
