通风管道加工过程中，应尽可能避免纵向接缝，但不应出现横向接缝。此外，根据设计清洁度要求，通风管的底切和四角需要用密封胶密封。此外，通气管接头的密封面应设置在通气管壁的正压侧。在风管加工过程中，通风管道不能设置加强框架或加强筋，因为这会对通风管道的质量产生一定的影响。

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.

风管加工不能采用“S”形切割和“C”形直角切割的连接方式。此外，一些特殊的通风管道不能堵塞。

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.

对于风管的连接部分，要进行紧密连接，中间所采用的垫片的厚度应该不小于3mm，垫片不应凸入管内，亦不宜突出法兰外。对于金属性的风管在转弯的时候要遵循严格的安装要求。对于塑料软管在弯道时要注意不应该有死弯或者塌陷。

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.

避免管道内空气热损失，还可以阻止热量散发到房间内让室温升高，避免人接触风道被烫伤。在夏季因输送气体温度低于周围环境空气露点温度，管道外壁会结露。这对集中空调系统的风道会加大冷量损失，同时凝结水滴会污染吊顶和墙地面，因此也应该进行保冷隔热处理，其实对于通风管道安装施工来说，对于我们生活中的重要性我们都知道，尤其是一些人在购房时也会考虑一下通风效果怎么样，房子在构建初期就会设计好各管道的位置，叁金来通风设备为人们拥有良好的生活品质做保障。

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.
