(1)连接简单

(1) the connection is simple

螺旋风管的安装减少了管与管之间的连接点，从而使得管件结合部的泄漏能降低到低程度。而且连接两个螺旋风管只需一个管接件，传统的矩形风管的连接则需要完全独立的双法兰系统。

The installation of the spiral air pipe reduces the connecting point between the pipe and the pipe, so that the leakage of the joint part of the pipe joint can be reduced to a low degree. Moreover, only one pipe connection is required to connect the two spiral pipes, and the traditional rectangular wind pipe connection requires a completely independent double flange system.

(2)标准化产品

(2) standardized products

螺旋风管的配件，包括管件和接头等，其生产已经实现高度自动化、系统化，并且有工业化的质量控制。

The fittings of spiral pipes, including fittings and joints, have been highly automated, systematic, and industrialized quality control.

(3)安装费用低

(3) the installation cost is low

螺旋风管的安装时间只有矩形风管的三分之一。

The installation time of the spiral air pipe is only 1/3 of the rectangular air duct.

(4)通常只需较小的安装空间

(4) usually only a small installation space

在不增加额外安装空间的前提下，数条平行的螺旋风管可替代矩形风管，所占用的空间也要比矩形风管少。

In the absence of additional installation space, several parallel spiral ducts can replace the rectangular duct and take less space than the rectangular duct.

(5)压降低

(5) reduce pressure;

螺旋风管的风阻要比矩形风管的小得多。

The wind resistance of the spiral pipe is much smaller than that of the rectangular duct.

(6)精密的咬口成型工艺

(6) precise bite forming process

所采用的模具均为特种钢材结构，即使使用几年，压制模具的表面仍能保持不变，镀锌钢板的表面不会受损，同时，接缝均匀平整、咬口紧密、连接力强、密封性好。

The mold is used in special steel structure, even if the use of a few years, the surface of the mold can still remain unchanged, the galvanized steel surface will not be damaged, at the same time, the joint smooth, bite tight, strong connection, good sealing performance.

(7)安全密封圈防漏系统，使用螺旋压制楞筋工艺

(7) the leakproof system of the safety sealing ring

该工艺能使螺旋风管具有佳的承受压力，咬口潜缝厚度是管体的四倍，增加了管道的刚性和优越性，并能承受大压力负荷而无损伤变形。并且，用材厚度可减小15%，降低了成本。

The process can make the spiral wind pipe have better pressure, and the thickness of the undercut is four times of that of the pipe, which increases the rigidity and superiority of the pipeline, and can bear large pressure load without damage deformation. In addition, the thickness of the material can be reduced by 15%, and the cost is reduced.

(8)保温用材少

(8) less heat preservation materials;

由于螺旋风管周长短，保温用材也可相应减少。

Due to the short circumference of the spiral wind pipe, the thermal insulation material can be correspondingly reduced.
