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.

當風道輸送一般氣體時，對黑鋼板風道應進行除銹、刷防銹漆處理，對含塵氣體可噴涂防磨損保護層，當周圍環境空氣濕度較大時，風道外壁需做防腐蝕、防銹處理。對輸送高溫、高濕氣體的鍍鋅鋼板風道內壁宜噴刷磷化底漆或其他耐蝕涂料。

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.

在風道輸送高溫氣體或低溫空氣時，風道外壁應做保溫(保冷)處理。濟南風管加工廠家表示輸送高溫氣體風管的保溫目的，一是防止管道內空氣的熱損失(出現在冬季集中空調系統);另外是防止在輸送廢熱蒸汽或高溫氣體時阻止熱量散發到房間內而使室溫升高，又可防止人接觸風道而被燙傷。

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.

通風管道加工廠家根據風機的特性曲線可以看出，風機可以在各種不同的風量下工作，風機在特性曲線的某一工作點上，風機的風壓與系統中的壓力獲得平衡，就確定了系統的風量。

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.

該管道由于長期的使用很容易積攢灰塵，在加上本身的安裝環境就非常的潮濕可容易滋生細菌，這些污染物如果不進行清洗很容易使人們出現過敏現象或其他疾病。

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.

風管的縱縫接頭，可根據實際情況挑選風管對應的方法。在中壓和低壓空氣管道中，經常使用按鈕式咬合銜接。

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.

濟南排煙管道對于矩形風管，接頭接合使用無任何壓力水平，因此按鈕接合能夠節約翻邊過程，并且大多數當時的管道縱向接頭用于接頭處的卡扣。濟南風管加工廠家表示對于筆直接頭和帶帽筆直接頭，鉚釘、自攻螺釘、點焊、壓花壓痕等，可用于緊固。

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.

管道的材質，我們在實際選擇通風管道的材質的時候要根據自身的需求選擇，這樣才能達到較好的性價比。

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.

管道材料的挑選，風管資料的挑選也對管道的施工質量有很大影響。一般，為了保證管道的分量，需要具有小厚度的管道，但另外，需要歸納考慮管道的尺度和壓力水平。從設計角度來看，值得注意的是，一個體系能夠同時具有對應于不同靜態壓力水平的幾個管道厚度。

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.
