螺旋风管的安装显著地减少了管与管之间的连接点，使管件结合部的泄漏减少到最低程度，典型的螺旋风管长度是3~6m，而典型的矩形风管的长度只有1~1.5m；且连接两个螺旋风管只需一个管接件，而传统的矩形风管的连接则常常需要一个完全独立的双法兰系统。

The installation of the spiral duct significantly reduces the connection point between the tube and the tube to minimize the leakage of the pipe joint, the typical length of the spiral duct is 3~6m, and the typical rectangular wind pipe is only 1~1.5m in length, and only one pipe connector is connected to the two spiral wind pipes, while the traditional rectangular wind pipe is often connected. A completely independent double flanged system is needed.

1、标准化产品

1. Standardized products

螺旋圆风管的配件（管件和接头）的生产已高度自动化、系统化，并具有工业化的质量控制。

The production of fittings (fittings and fittings) of spiral air ducts has been highly automated and systematic, and has industrialized quality control.

2、安装费用低

2. Low installation cost

圆形风管系统的安装时间只有相类似的矩形管道的1/3。

The installation time of the circular duct system is only 1/3 similar to that of the rectangular pipe.

3、通常只需较小的安装空间

3. Usually only a small installation space is needed

在不增加任何压降的情况下，相同的安装空间内直径为200mm的圆形管道可取代250×150mm的矩形管道。在不增加额外安装空间的前提下，数条平行的圆形管道可取代扁平矩形管道。考虑了所有的因素，在绝大多数情况下，圆形管道所占用的空间都要少于矩形管道。对同样的压力特性，数条圆形管道的安装空间常常与一条矩形管道的的安装空间相同或更少。许多矩形管道系统安装时需要4螺栓系统，因而在管道的各个方向增加40~80mm。

Without increasing any pressure drop, a circular pipe with a diameter of 200mm can be replaced by a 250 * 150mm rectangular pipe in the same installation space. Without additional installation space, several parallel circular pipes can replace flat rectangular pipes. Considering all the factors, in most cases, the space occupied by a circular pipe is less than that of a rectangular pipe. For the same pressure characteristics, the installation space of several circular pipes is often the same or less than the installation space of a rectangular pipe. Many rectangular pipe systems need 4 bolt systems when installing, thus increasing 40~80mm in all directions of the pipeline.

4、压降低：圆形风管的风阻比矩形风管的风阻要小得多。

4, pressure reduction: the wind resistance of the circular duct is much smaller than that of the rectangular duct.

5、精密的咬口成型工艺：进口设备所采用的模具均为特种钢材结构，即使使用了三五年，其压制模具的表面仍保持不变，使得镀锌钢板的表面不受损伤，大大的延长了风管的使用寿命，同时接缝均匀平整、咬口紧密、连接力强、密封性好。

5, the precise bite forming process: the mould used by the imported equipment is the special steel structure. Even if it is used for 35 years, the surface of the pressing die remains unchanged, which makes the surface of the galvanized steel plate not damaged, greatly prolongs the service life of the wind pipe, and the joint is uniform and smooth, the bite is tight, and the connecting force is strong. Good seal.

6、安全密封圈防漏系统

6. Safety sealing ring leakage prevention system

7、精巧的螺旋压制楞筋工艺使螺旋风管具有承受压力的最佳强度，增加螺旋型楞筋后，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，能承受最大的压力负荷而无损变形，用材厚度可减小15%，降低成本。

7, the exquisite spiral crenching rib technology makes the spiral pipe with the best strength to bear pressure. After increasing the spiral type, the thickness of the bite seam is four times that of the tube body. The rigidity of the pipe is very large, which shows the strong superiority, can withstand the maximum pressure load without damage, and the thickness of the material can be reduced by 15% and the cost is reduced. .
