In the workshop ventilation and cooling project, the processing and installation of environmental friendly air-conditioning ventilation pipes is a very important link. There are some specific requirements and specifications for the processing and installation methods of ventilation pipes, which should be learned by everyone or the company. What are the processing specifications for ventilation ducts? Then I will explain it to you.

通風管加工前的注意事項：

Precautions before processing of vent pipe:

一：規格。這里所說的規格是通風管道的基本規格，以及我們需要的通風管道的尺寸和尺寸。值得注意的是，我們在確定規格時與空調的使用相關聯。只有這樣，才能保證在設置好通風管道的規格后，才能與空調連接，發揮其作用，完成其使用效果。

1： Specifications. The specifications mentioned here are the basic specifications of ventilation ducts, as well as the sizes and dimensions of ventilation ducts we need. It is worth noting that our specifications are related to the use of air conditioners. Only in this way can we ensure that after the specification of the ventilation pipe is set, it can be connected with the air conditioner, play its role and complete its use effect.

二：類型。通風管的種類很多。不同類型的空調與管道配合使用，效果不同，尤其是通風管道的隔熱。因此，如果我們要加工通風管道以更好地與空調配合使用，我們還需要在加工前考慮其類型，這是確保它們工作并發揮有利作用的良好條件。

2： Type. There are many kinds of ventilation pipes. Different types of air conditioners are used together with pipes with different effects, especially the heat insulation of ventilation pipes. Therefore, if we want to process ventilation ducts to better work with air conditioners, we also need to consider their types before processing, which is a good condition to ensure that they work and play a beneficial role.

總之，在加工通風管之前，一定要結合空調的基本情況，注意通風管的規格和類型。不同的空調需要不同的通風管、不同的規格、不同的類型。因此，當涉及到通風管道時，考慮上述問題。

In a word, before processing the ventilation pipe, we must pay attention to the specification and type of the ventilation pipe in combination with the basic conditions of the air conditioner. Different air conditioners need different ventilation pipes, different specifications and different types. Therefore, when it comes to ventilation ducts, consider the above issues.

通風管道加工規范：

Processing specification of ventilation duct:

1、風管加工時，為保證風管生產后的強度，切割時應預留20mm鋁箔作為保護邊;

1. During air duct processing, 20mm aluminum foil shall be reserved as the protective edge during cutting to ensure the strength of air duct after production;

2、風管在拼接前預先組裝好，檢查接縫是否嚴密，尺寸是否符合要求。根據季節溫度、濕度和粘合劑特性確定佳粘合時間。加入后，用正方形檢查。鋼帶。垂直度和對角線偏差的調整符合規定。

2. The air duct shall be pre assembled before splicing to check whether the joint is tight and whether the size meets the requirements. Determine the best bonding time according to the seasonal temperature, humidity and adhesive properties. After adding, check with a square. Steel strip. The adjustment of perpendicularity and diagonal deviation shall meet the requirements.

3、通風管道加工時，請做好現場預制板、管道成品的保護工作。

3. During the processing of ventilation pipes, please protect the prefabricated boards and finished pipes on site.

4、連接安裝后，應檢查接頭接頭，接頭后應平整、彎曲。錯位局部裂紋、大于2mm的縫隙等缺陷。

4. After connection and installation, check the joint, which shall be flat and bent. Dislocation, local cracks, cracks larger than 2mm and other defects.

5、風管支架與吊架的距離符合標準。

5. The distance between the air duct support and the hanger conforms to the standard.
