現如今，通風管道的應用越來越普遍，所以市面上也出現了各種材質的通風管道，那么通風管道材質種類有哪些呢？下面山東通風管道加工人員為您講講。

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、薄鋼板風管。用薄鋼板制作通風管道，以采用低碳鋼板為宜，以冷軋鋼板適用于通風與空調工程。厚度在1．2mm以內的薄鋼板風管采用咬口連接，厚度2mm以內時采用焊接。根據有關規(guī)定，薄鋼板風管與鍍鋅鋼板風管，當矩形風管邊長≥630mm和保溫風管邊長≥800mm，其管段長度在1．2mm以上的均應采取加固措施。一般使用角鋼加固風管，邊有采用起高接頭（立咬口〕或在風管管壁上滾槽壓出凸棱等加固方法。風管與風管連接一般采用角鋼或扁鋼法蘭。

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、鍍鋅鋼板風管。鍍鋅鋼板施工時應注意使鍍鋅層不受破壞，應采用咬口和鉚接。

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、不銹鋼板風管。在加工時應防止板材表面產生劃痕刮傷和凹陷等缺陷，且不得用鐵錘敲打，避免破壞合金元素的晶體結構，否則被鐵錘敲擊處會出現腐蝕。不銹鋼的強度較高、彈性好，當管壁厚度大于0．8mm時，一般采用焊接，厚度在0．8mm以下時，采用咬口連接。不銹鋼風管連接使用的法蘭，一般是把不銹鋼板剪成條形，矩形法蘭可按尺寸采用焊接，圓形法蘭則采用冷彎法加工。

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.

采用鍍鋅薄鋼板制作，有不易生銹，保溫和消聲功能，制作安裝周期長的特點。鍍鋅風管特別適合含濕量小的一般性氣體的輸送。對于鍍鋅風管來說，它憑借其良好的防火性能能很好的應用于凈化系統(tǒng)送回風管、空調通風管、工業(yè)送排風通風管、系統(tǒng)吸排風管、礦用抽放瓦斯管、礦用涂膠布風筒等眾多場合。

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.

要知道鍍鋅風管的鋅鍍層經鈍化處理、染色或涂覆護光劑后，能顯著提高其防護性和裝飾性。并且鍍鋅風管的防火性能主要體現在，它具有不燃性，但是有一點需要注意的是，它的保溫層是否燃燒要依材質而定，我們建議鍍鋅風管的材質要選用離心玻璃棉等不燃保溫材料。

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.

總之，不同材質的風管性質方面有所不同，由于材質的選擇關系到工程質量以及后期的設備維護保養(yǎng)是否方便等問題，所以選擇時一定要仔細考慮。更多了解就來我們網站http://www.shyrzs.com看看吧。

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.
