现如今，通风管道的应用越来越普遍，所以市面上也出现了各种材质的通风管道，那么通风管道材质种类有哪些呢？下面
山东通风管道加工人员为您讲讲。
Nowadays, the application of ventilation pipes is more and more common, so there are various materials of ventilation pipes in the market. What are the types of ventilation pipes? Next, Shandong ventilation pipe processing personnel will tell you.
1、薄钢板风管。用薄钢板制作通风管道，以采用低碳钢板为宜，以冷轧钢板适用于通风与空调工程。厚度在1．2mm以内的薄钢板风管采用咬口连接，厚度2mm以内时采用焊接。根据有关规定，薄钢板风管与镀锌钢板风管，当矩形风管边长≥630mm和保温风管边长≥800mm，其管段长度在1．2mm以上的均应采取加固措施。一般使用角钢加固风管，边有采用起高接头（立咬口〕或在风管管壁上滚槽压出凸棱等加固方法。风管与风管连接一般采用角钢或扁钢法兰。
1. Sheet steel air duct. The ventilation pipe is made of thin steel plate, and the low-carbon steel plate is suitable, and the cold-rolled steel plate is suitable for ventilation and air conditioning engineering. The thin steel sheet air duct with a thickness of less than 1.2mm is connected by undercut, and the air duct with a thickness of less than 2mm is welded. According to relevant regulations, when the side length of rectangular air duct is ≥ 630mm and the side length of thermal insulation air duct is ≥ 800mm, the reinforcement measures shall be taken for the steel sheet air duct and galvanized steel sheet air duct with the length of pipe section above 1.2mm. Generally, angle steel is used to reinforce the air duct, and some reinforcement methods such as lifting joint (vertical bite) or rolling groove and pressing out convex edge on the air duct wall are used. Generally, angle steel or flat steel flange is used to connect the air duct and the air duct.
2、镀锌钢板风管。镀锌钢板施工时应注意使镀锌层不受破坏，应采用咬口和铆接。
2. Galvanized steel air duct. During the construction of galvanized steel plate, attention shall be paid to ensure that the galvanized layer is not damaged, and undercut and riveting shall be adopted.
3、不锈钢板风管。在加工时应防止板材表面产生划痕刮伤和凹陷等缺陷，且不得用铁锤敲打，避免破坏合金元素的晶体结构，否则被铁锤敲击处会出现腐蚀。不锈钢的强度较高、弹性好，当管壁厚度大于0．8mm时，一般采用焊接，厚度在0．8mm以下时，采用咬口连接。不锈钢风管连接使用的法兰，一般是把不锈钢板剪成条形，矩形法兰可按尺寸采用焊接，圆形法兰则采用冷弯法加工。
3. Stainless steel plate air duct. During processing, scratches, scratches, dents and other defects on the surface of the plate shall be prevented, and hammers shall not be used to avoid damaging the crystal structure of the alloy elements, otherwise the corrosion center will appear at the place struck by the hammer. Stainless steel has high strength and good elasticity. When the pipe wall thickness is greater than 0.8mm, welding is generally used. When the thickness is less than 0.8mm, bite connection is used. The flanges used for the connection of stainless steel air pipes are generally cut into strips. The rectangular flanges can be welded according to the size, and the circular flanges are processed by cold bending.
采用镀锌薄钢板制作，有不易生锈，保温和消声功能，制作安装周期长的特点。镀锌风管特别适合含湿量小的一般性气体的输送。对于镀锌风管来说，它凭借其良好的防火性能能很好的应用于净化系统送回风管、空调通风管、工业送排风通风管、系统吸排风管、矿用抽放瓦斯管、矿用涂胶布风筒等众多场合。
It is made of galvanized steel sheet, which is not easy to rust, has the functions of heat preservation and noise elimination, and has the characteristics of long production and installation cycle. Galvanized air duct is especially suitable for conveying general gas with low moisture content. For galvanized air duct, it can be well used in many occasions such as supply and return air duct of purification system, ventilation duct of central air conditioning, industrial supply and exhaust air duct, suction and exhaust air duct of environmental protection system, mine drainage gas duct, mine coated cloth air duct, etc. due to its good fire performance.
要知道镀锌风管的锌镀层经钝化处理、染色或涂覆护光剂后，能显着提高其防护性和装饰性。并且镀锌风管的防火性能主要体现在，它具有不燃性，但是有一点需要注意的是，它的保温层是否燃烧要依材质而定，我们建议镀锌风管的材质要选用离心玻璃棉等不燃保温材料。
We should know that the zinc coating of galvanized air duct can significantly improve its protection and decoration after passivation, dyeing or coating with light protecting agent. Moreover, the fire protection performance of galvanized air duct is mainly reflected in its incombustibility. However, it should be noted that whether its insulation layer is burnt depends on the material. We suggest that the material of galvanized air duct should be non combustible insulation materials such as centrifugal glass wool.
In short, the properties of air ducts made of different materials are different. As the selection of materials is related to the quality of the project and the convenience of equipment maintenance in the later stage, it must be carefully considered when selecting.
