1.螺旋风管的安装大大减少了管道之间的连接点，减少了管件连接处的泄漏。典型的螺旋风管长度为3 ~ 6m，而典型的矩形风管长度仅为1 ~ 1.5m;连接两个螺旋风管只需要一个连接器，而传统的矩形风管往往需要一个完全独立的双法兰系统。
1. The installation of spiral air duct greatly reduces the connection points between pipes and reduces the leakage at the connection of pipe fittings. The length of typical spiral air duct is 3 ~ 6m, while the length of typical rectangular air duct is only 1 ~ 1.5m; Connecting two spiral air ducts requires only one connector, while traditional rectangular air ducts often require a completely independent double flange system.
2. 标准化的产品。
2. Standardized products.
螺旋圆管配件(管件、接头)的生产已高度自动化、系统化，质量控制已工业化。
The production of spiral pipe fittings (pipe fittings, joints) has been highly automated and systematic, and the quality control has been industrialized.
3.较低的安装成本。
3. Low installation cost.
圆形风管系统的安装时间仅为类似矩形风管系统的1 / 3。
The installation time of circular duct system is only 1 / 3 of that of similar rectangular duct system.
4. 通常只需要很小的安装空间。
4. Usually only a small installation space is required.
在相同的安装空间内，一个200mm直径的圆管可以代替250mm直径的管，而不增加任何压降× 150mm矩形管。在不增加安装空间的前提下，可以用几根平行的圆管代替扁的矩形管。考虑到所有因素，在大多数情况下，圆形管所占用的空间小于矩形管。对于相同的压力特性，几根圆形管道的安装空间往往等于或小于一个矩形管道的安装空间。很多矩形管道系统在安装时需要4个螺栓系统，所以在管道的各个方向都增加了40-80mm。
In the same installation space, a 200mm diameter round pipe can replace a 250mm diameter pipe without increasing any pressure drop × 150mm rectangular pipe. On the premise of not increasing the installation space, several parallel circular tubes can be used to replace the flat rectangular tubes. Considering all factors, in most cases, circular tubes occupy less space than rectangular tubes. For the same pressure characteristics, the installation space of several circular pipes is often equal to or less than that of a rectangular pipe. Many rectangular pipe systems require four bolt systems during installation, so 40-80mm is added in all directions of the pipe.
5. 减压:众所周知，圆形风管的风阻要比矩形风管的风阻小得多。
5. Decompression: as we all know, the wind resistance of circular air duct is much smaller than that of rectangular air duct.
6. 精密的咬口成型工艺:进口设备使用的模具为特殊钢结构。即使使用了三、五年，压模表面保持不变，使镀锌钢板表面不受损坏，风管的使用寿命大大延长。同时接头均匀，夹紧，连接力强，密封性好。
6. Precise biting forming process: the mold used by imported equipment is of special steel structure. Even if it has been used for three or five years, the die surface remains unchanged, so that the galvanized steel surface is not damaged, and the service life of the air duct is greatly extended. At the same time, the joint is uniform, clamped, with strong connection force and good sealing.
7. 安全密封圈防漏系统。
7. Safety sealing ring leak proof system.
8. 精美的螺旋压筋工艺，使螺旋风管具有优异的承受压力的强度。增加螺旋肋后，咬边缝厚度是管体的4倍，管道的刚性非常大，显示出坚固性的优点。可承受很大压力载荷而不变形，材料厚度可减少15%，降低成本。
8. The exquisite spiral reinforcement technology makes the spiral air duct have excellent strength to bear pressure. After adding spiral ribs, the thickness of undercut joint is 4 times that of the pipe body, and the rigidity of the pipe is very large, showing the advantage of firmness. It can bear great pressure load without deformation, and the material thickness can be reduced by 15% to reduce the cost.
9. 在相同截面积下，长宽比为1:3的矩形风管周长比螺旋风管长40%;同样，由于螺旋风管的周长较短，保温材料也可相应减少。
9. Under the same cross-sectional area, the perimeter of rectangular duct with length width ratio of 1:3 is 40% longer than that of spiral duct; Similarly, due to the short circumference of the spiral duct, the insulation material can be reduced accordingly.
10. 管道布局美观，立体感强:当管道须作为一种建筑特色暴露出来时，优雅成型的法兰风管将是合适的选择。
10. The pipeline layout is beautiful and has a strong three-dimensional sense: when the pipeline must be exposed as an architectural feature, the elegant flange air duct will be the appropriate choice.
