In fact, an important part of the ventilation system is Jinan ventilation pipe, which is to ensure the rationality of air circulation. On the premise of ensuring the use effect, reasonably determine the structure, layout and size of the air pipe. What do you know about it? Next, Jinan smoke exhaust pipe installation manufacturer Gao Shi will introduce it to you below.

当风道输送一般气体时，对黑钢板风道应进行除锈、刷防锈漆处理，对含尘气体可喷涂防磨损保护层，当周围环境空气湿度较大时，风道外壁需做防腐蚀、防锈处理。对输送高温、高湿气体的镀锌钢板风道内壁宜喷刷磷化底漆或其他耐蚀涂料。

When the air duct conveys general gas, the black steel plate air duct shall be derusted and painted with antirust paint. The dust containing gas can be coated with anti-wear protective layer. When the ambient air humidity is large, the outer wall of the air duct shall be treated with anti-corrosion and antirust treatment. The inner wall of the air duct of the galvanized steel plate conveying high temperature and high humidity gas should be sprayed with phosphating primer or other corrosion-resistant coating.

在风道输送高温气体或低温空气时，风道外壁应做保温(保冷)处理。济南风管加工厂家表示输送高温气体风管的保温目的，一是防止管道内空气的热损失(出现在冬季集中空调系统);另外是防止在输送废热蒸汽或高温气体时阻止热量散发到房间内而使室温升高，又可防止人接触风道而被烫伤。

When conveying high temperature gas or low temperature air in the air duct, the outer wall of the air duct shall be insulated (insulated). Jinan air duct manufacturer said that the purpose of heat preservation of high-temperature air duct is to prevent the heat loss of the air in the duct (appearing in the centralized air conditioning system in winter); in addition, to prevent the heat from radiating into the room and raising the room temperature when transporting waste hot steam or high-temperature gas, and to prevent people from contacting the air duct and being scalded.

通风管道加工厂家根据风机的特性曲线可以看出，风机可以在各种不同的风量下工作，风机在特性曲线的某一工作点上，风机的风压与系统中的压力获得平衡，就确定了系统的风量。

According to the characteristic curve of the fan, the manufacturer of the ventilation pipe can see that the fan can work under various air volumes. When the fan works at a certain working point of the characteristic curve, the air pressure of the fan is balanced with the pressure in the system, and the air volume of the system is determined.

该管道由于长期的使用很容易积攒灰尘，在加上本身的安装环境就非常的潮湿可容易滋生细菌，这些污染物如果不进行清洗很容易使人们出现过敏现象或其他疾病。

Due to the long-term use of the pipeline, it is easy to accumulate dust. In addition, the installation environment itself is very humid, which can easily breed bacteria. If these pollutants are not cleaned, it is easy for people to have allergies or other diseases.

风管的纵缝接头，可根据实际情况挑选风管对应的方法。在中压和低压空气管道中，经常使用按钮式咬合衔接。

For the longitudinal joint of air duct, the corresponding method of air duct can be selected according to the actual situation. In the medium and low pressure air pipes, button type engagement is often used.

济南排烟管道对于矩形风管，接头接合使用无任何压力水平，因此按钮接合能够节约翻边过程，并且大多数当时的管道纵向接头用于接头处的卡扣。济南风管加工厂家表示对于笔直接头和带帽笔直接头，铆钉、自攻螺钉、点焊、压花压痕等，可用于紧固。

Jinan smoke exhaust pipe has no pressure level for the joint of rectangular air pipe, so the button joint can save the flanging process, and most of the pipe longitudinal joints at that time are used for the buckle at the joint. Jinan air duct manufacturer said for straight joints and cap pen direct head, rivets, self tapping screws, spot welding, embossing indentation, etc., can be used for fastening.

管道的材质，我们在实际选择通风管道的材质的时候要根据自身的需求选择，这样才能达到较好的性价比。

For the material of the pipe, we should choose the material according to our own needs when we actually choose the material of the ventilation pipe, so as to achieve better cost performance.

管道材料的挑选，风管资料的挑选也对管道的施工质量有很大影响。一般，为了保证管道的分量，需要具有小厚度的管道，但另外，需要归纳考虑管道的尺度和压力水平。从设计角度来看，值得注意的是，一个体系能够同时具有对应于不同静态压力水平的几个管道厚度。

The selection of pipeline materials and air duct data also have a great impact on the construction quality of the pipeline. Generally, in order to ensure the component of the pipeline, the pipeline with small thickness is needed, but in addition, the scale and pressure level of the pipeline need to be considered. From the design point of view, it is worth noting that a system can simultaneously have several pipe thicknesses corresponding to different static pressure levels.
