通風管道在運輸過程應有防止損傷風管的保護措施。榫接風管的連接在榫口處涂膠粘劑，是為增強接頭處的強度。當風管采用地面預組裝后架空安裝時，限制預組裝的長度是為了遮免風管因自重產生的彎曲而破壞構件接口。玻璃纖維復合板風管端口為切割面時，在裝配法蘭連接件前應將管端切口面用膠帶或膠液進行封堵，才能防止玻璃纖維外露和飛散。

The ventilation duct shall be protected from damage during transportation. For the connection of tenon air duct, adhesive shall be applied at the tenon to enhance the strength of the joint. When the air duct is installed overhead after ground pre assembly, the length of pre assembly is limited to prevent the bending of the air duct due to its own weight from damaging the component interface. When the end of the fiberglass composite board air duct is the cutting surface, the cut surface of the duct end shall be sealed with tape or glue before assembling the flange connector to prevent the fiberglass from being exposed and flying away.

工作通道寬度應滿足施工要求，在通道內應有覆蓋物，鋪設腳手架。作業(yè)過程中，應隨時派專人檢查工作通道和腳手架。如發(fā)現(xiàn)變形和位移，應及時采取措施，并確認。

The width of the working passage shall meet the construction safety requirements, and the passage shall be covered with scaffolding. During the operation, special personnel shall be assigned to check the working channel and scaffold at any time. If deformation and displacement are found, safety measures shall be taken in time and safety shall be confirmed.

直線的實長或平面的實形，確定展開方法和畫展開圖這幾個部分。在進行展開下料前，要熟悉施工圖紙，這是一項準備工作，主要是對將要展開的關鍵和部件有所了解，濟南通風管道管道在圖紙上的尺寸大小、制作材料等。而對于比較復雜的管件，則需要對施工圖紙進行反復閱讀和分析，針對有關問題要及時提出和解決。由于通風管件及其部件在圖紙上都是幾何圖形，而對形體進行分析的主要目的就是將復雜的幾何圖形簡單化。通過分析，以便找到恰當的展開方法。

The real length of a straight line or the real shape of a plane, the determination of the expansion method and the drawing of the expansion diagram. Before launching blanking, first get familiar with the construction drawings, which is a preparatory work, mainly to understand the key and components to be launched, the size and fabrication materials of Jinan ventilation pipeline on the drawings. For more complex pipe fittings, the construction drawings need to be read and analyzed repeatedly, and relevant problems should be put forward and solved in time. As the ventilation pipe fittings and their components are geometric figures on the drawings, the main purpose of shape analysis is to simplify the complex geometric figures. Through analysis, in order to find the appropriate expansion method.

當測量斷面設在彎頭、三通等異形部件后面時，距這些部件的距離應大于4～5倍管道直徑。濟南通風管道測試現(xiàn)場難于滿足要求時，為減少誤差可適當增加測點。但是，測量斷面位置距異形部件的Z小距離少是管道直徑的1.5倍。通風管道風管主要應用在工業(yè)及建筑工程中， 應用領域有：適用于工業(yè)、各種建筑的空調通風工程安裝，廣泛應用在食品加工、機械制造、藥業(yè)制品、電子工業(yè)、購物、棉紡織、體育娛樂場所、酒店、賓館、、寫字樓、、小型別墅、航空航天制造等領域.

When the measuring section is set behind the elbow, tee and other special-shaped parts, the distance from these parts shall be more than 4-5 times the pipe diameter. When it is difficult to meet the requirements of Jinan ventilation pipeline testing site, the measuring points can be appropriately increased to reduce the error. However, the Z small distance between the measuring section location and the profiled part is at least 1.5 times of the pipe diameter. The air duct of ventilation duct is mainly used in industrial and architectural projects. The application fields are: applicable to the installation of air conditioning and ventilation projects in industrial and various buildings, widely used in food processing, machinery manufacturing, pharmaceutical products, electronic industry, shopping centers, cotton textiles, sports and entertainment venues, hotels, hotels, supermarkets, office buildings, government agencies, small villas, aerospace manufacturing and other fields
