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.

剛度、強度及承壓能力鍍鋅風管鐵皮厚度根據管徑相應調整，采用法蘭及法蘭框加固，剛度、強度及承壓能力好。雙面彩板復合風管剛度、強度及承壓能力均略低于鍍鋅風管。

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.

因為螺旋風管也屬于風管的一類,在安裝時候必須遵守管道施工原則,在安裝期間一定要用的工具去操作,在風管的移動期間一定要注意保護好螺旋風管的產品完整,運到目的地之后,先組裝,切割好接頭,確保螺旋風管沒有缺陷,而且螺旋風管在設計管道的時候一定要按照標準的一比三的比例去設計,一個的螺旋風管應盡量少突出部件,按照好這些程序去做,風管就能很順利的安裝起來,無論是風管安裝還是其他行業安裝,首先要保證安裝人士的安全,而且還要保障使用期間不能出現重大事故

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

飛式切割作用-螺旋風管可連續生產，不致因切割機器停止運作。

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

安全性高-切割后邊緣平整，沒有毛刺，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.
