Introduction to the performance of double-sided color steel plate composite air duct board: The board is mechanically processed, with a thickness of about 0.3mm. It cannot be adjusted according to the pipe diameter, and there are no additional reinforcement measures. In terms of strength, it is slightly insufficient when applied to large-diameter air ducts. In addition, due to the separation of the inner and outer surfaces of the double-layer color steel plate, the inner steel plate bears greater pressure, and the deformation is uneven with the outer surface, which will affect the overall performance of the air duct. The steel plate thickness and reinforcement method of galvanized air ducts can be flexibly adjusted according to regulatory requirements.

刚度、强度及承压能力镀锌风管铁皮厚度根据管径相应调整，采用法兰及法兰框加固，刚度、强度及承压能力好。双面彩板复合风管刚度、强度及承压能力均略低于镀锌风管。

The thickness of galvanized air duct iron sheet is adjusted according to the pipe diameter, and reinforced with flanges and flange frames, resulting in good stiffness, strength, and pressure bearing capacity. The stiffness, strength, and pressure bearing capacity of the double-sided color plate composite air duct are slightly lower than those of the galvanized air duct.

因为螺旋风管也属于风管的一类,在安装时候必须遵守管道施工原则,在安装期间一定要用的工具去操作,在风管的移动期间一定要注意保护好螺旋风管的产品完整,运到目的地之后,先组装,切割好接头,确保螺旋风管没有缺陷,而且螺旋风管在设计管道的时候一定要按照标准的一比三的比例去设计,一个的螺旋风管应尽量少突出部件,按照好这些程序去做,风管就能很顺利的安装起来,无论是风管安装还是其他行业安装,首先要保证安装人士的安全,而且还要保障使用期间不能出现重大事故

Because spiral air ducts also belong to the category of air ducts, they must comply with the principles of pipeline construction during installation. During installation, professional tools must be used to operate them. During the movement of the air duct, attention must be paid to protecting the integrity of the spiral air duct product. After arriving at the destination, they should be assembled and cut to ensure that there are no defects in the spiral air duct. Moreover, spiral air ducts must be designed according to the standard ratio of one to three when designing the pipeline, A spiral air duct should have as few protruding parts as possible. By following these procedures well, the duct can be installed smoothly. Whether it is installed in the duct or in other industries, the first step is to ensure the safety of the installation personnel, and also to ensure that no major accidents occur during use

飞式切割作用-螺旋风管可连续生产，不致因切割机器停止运作。

Flying cutting function - spiral air ducts can be continuously produced without stopping the cutting machine.

安全性高-切割后边缘平整，没有毛刺，省去清除毛刺程序。

High safety - after cutting, the edges are flat and free of burrs, eliminating the need for deburring procedures.

可切割任何材料之螺旋風管，飛式切割器解決了老式切割技術所不能解決的任何問題，沒有毛刺、沒有噪音、沒有鋸屑、沒有油漬、不會鋸齒狀及沒有火花，施工安全性高。

The spiral air duct can cut any material, and the flying cutter solves any problem that old-fashioned cutting technology cannot solve. It is free of burrs, noise, sawdust, oil stains, serrations, and sparks, and has high construction safety.
