通風管道加工過程中，應盡可能避免縱向接縫，但不應出現橫向接縫。此外，根據設計清潔度要求，通風管的底切和四角需要用密封膠密封。此外，通氣管接頭的密封面應設置在通氣管壁的正壓側。在風管加工過程中，通風管道不能設置加強框架或加強筋，因為這會對通風管道的質量產生一定的影響。

During the processing of ventilation ducts, longitudinal joints should be avoided as much as possible, but transverse joints should not occur. In addition, according to the cleanliness requirements of the design, the bottom cut and four corners of the ventilation pipe need to be sealed with sealant. In addition, the sealing surface of the ventilation pipe joint should be set on the positive pressure side of the ventilation pipe wall. During the processing of air ducts, reinforcing frames or ribs should not be installed in the ventilation ducts, as this will have a certain impact on the quality of the ventilation ducts.

風管加工不能采用“S”形切割和“C”形直角切割的連接方式。此外，一些特殊的通風管道不能堵塞。

The connection method of "S" shaped cutting and "C" shaped right angle cutting cannot be used for the processing of air ducts. In addition, some special ventilation ducts cannot be blocked.

對于風管的連接部分，要進行緊密連接，中間所采用的墊片的厚度應該不小于3mm，墊片不應凸入管內，亦不宜突出法蘭外。對于金屬性的風管在轉彎的時候要遵循嚴格的安裝要求。對于塑料軟管在彎道時要注意不應該有死彎或者塌陷。

For the connection part of the air duct, it should be tightly connected, and the thickness of the gasket used in the middle should not be less than 3mm. The gasket should not protrude into the pipe or outside the flange. For metallic air ducts, strict installation requirements should be followed when turning. For plastic hoses, it is important to be careful not to have dead bends or collapses during bends.

避免管道內空氣熱損失，還可以阻止熱量散發到房間內讓室溫升高，避免人接觸風道被燙傷。在夏季因輸送氣體溫度低于周圍環境空氣露點溫度，管道外壁會結露。這對集中空調系統的風道會加大冷量損失，同時凝結水滴會污染吊頂和墻地面，因此也應該進行保冷隔熱處理，其實對于通風管道安裝施工來說，對于我們生活中的重要性我們都知道，尤其是一些人在購房時也會考慮一下通風效果怎么樣，房子在構建初期就會設計好各管道的位置，叁金來通風設備為人們擁有良好的生活品質做保障。

Avoiding heat loss from the air inside the duct can also prevent heat from radiating into the room, causing room temperature to rise, and preventing people from getting burned in contact with the air duct. In summer, due to the temperature of the transported gas being lower than the dew point temperature of the surrounding air, the outer wall of the pipeline will condense. This will increase the cooling loss of the air ducts in the centralized air conditioning system, and condensate droplets will pollute the suspended ceiling and wall floor. Therefore, cold insulation treatment should also be carried out. In fact, for the installation and construction of ventilation ducts, we all know the importance in our daily lives, especially when purchasing a house, some people will also consider the ventilation effect. In the early stages of building construction, the position of each pipeline will be designed, Sanjinlai ventilation equipment ensures that people have a good quality of life.
