(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

螺旋风管的安装保定平面设计培训 收费岛模具 挡土墙模具 防撞墙模具 防撞墙模具 防撞护栏模具 大棚遮阳网 遮阴网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.
