1、镀锌铁皮风管

1. Galvanized iron pipe

这是一种使用较早且目前仍然使用的一种通风管道，使用镀锌铁皮加工而成，适用于含湿气量比较小的气体输送，但由于出现时间较早，存在很多不完善的地方，容易生锈，抗腐蚀能力较差，缺乏消声和保温功能，需要另设消声器，并需另加保温防护层，因而制作周期较长，且安装不方便，使用时仍会存在较大噪音，使用寿命较短。

It is a kind of ventilated pipe which is used earlier and still used at present. It is made of galvanized iron sheet. It is suitable for gas conveying with relatively small moisture content. However, because of the early time, there are many imperfect places, easy to rust, poor corrosion resistance, lack of sound and heat preservation, and need to be set aside. The sound device needs additional insulation protection layer, so the production cycle is longer and the installation is inconvenient. There will be much noise and short service life when used.

2、玻璃钢风管

2, FRP wind pipe

玻璃钢风管是一种使用比较新型的氯氧化镁材料制作成的通风管道，并使用玻璃纤维布强化材料性能，经过水化反应，进行固化后方制成。此种管道具有抗燃、抗腐蚀，以及硬度大但分量重的特点，也不具备消声和保温功能，需要加设消声器和保温防护层，才能保证暖通空调系统的较好运行，因此，在制作和安装时，也需要花费较多的时间和精力，且一旦设计完成，还不容易变更修改，给使用过程带来了一定麻烦。

The FRP wind pipe is a kind of ventilation pipe made of a new type of chlorine Magnesium Oxide material, and it is made by using glass fiber cloth to strengthen the material property and after the hydration reaction. This kind of pipe has the characteristics of anti burning, corrosion resistance, large hardness but heavy weight. It does not have the function of noise elimination and insulation. It is necessary to add the muffler and insulation protection layer to ensure the good operation of the HVAC system. Therefore, it also takes a lot of time and energy when it is made and installed, and once the design is finished. It is not easy to change and modify, which brings some trouble to the use process.

3、复合玻纤板风管

3. Composite glass fiberboard wind pipe

复合玻纤板风管又称新型超级风管，是近些年随着科技的不断进步，推出的一种新型的具有科技含量的一种通风管道。以离心玻纤板为主要材料，并在管道外部设防潮铝箔布，内部使用玻璃丝布，并进行喷胶处理。复合玻纤板风管材质轻，体积小，容易安装，节省空间，容易修改，且抗燃、抗潮湿，并能消声、保温，减少漏风量，使用方便，寿命较长，性价比高，在当前通风管道中具有很好的应用优势。

The composite glass fiberboard wind pipe, also known as a new type of super wind pipe, is a new type of ventilation pipe with scientific and technological content in recent years, with the continuous progress of science and technology. The centrifugal fiberglass board is used as the main material, and the aluminum foil cloth is laid on the outside of the pipe, and the glass cloth is used internally, and the glue is processed. The composite glass fiber plate wind pipe is light, small, easy to install, space saving, easy to modify, and anti burning, anti humid, and can reduce sound, heat insulation, reduce air leakage, easy to use, long life, cost-effective, in the current ventilation pipe has a good advantage in the application.
