鍍鋅板風管吊架的安裝要求有哪些：

What are the installation requirements for galvanized sheet air duct hangers

1，鍍鋅鋼管分支，吊架不應設置在風口，閥門，檢查門和自動控制機構中，風口或塞入管道的距離不應小于200mm。

1. Galvanized steel pipe branches and hangers should not be installed in air vents, valves, inspection doors, and automatic control mechanisms. The distance between air vents or pipes should not be less than 200mm.

2，箍支撐，折疊角度應平直，箍應緊密鍍鋅板風管。安裝在支架上的圓形鍍鋅板風管應配備支架和環箍，其弧度應均勻，不銹鋼風管與鍍鋅板風管的外徑一致。檢驗數量：按數量計10％，不少于一個系統。檢驗方法：計量，觀察和檢驗。

2. The hoop support should have a flat folding angle, and the hoop should be tightly galvanized sheet air duct. The circular galvanized sheet air duct installed on the bracket should be equipped with brackets and clamps, and its curvature should be uniform. The outer diameter of the stainless steel air duct should be consistent with that of the galvanized sheet air duct. Inspection quantity: 10% by quantity, not less than one system. Inspection methods: measurement, observation, and inspection.

3，吊架螺絲孔采用機械加工。動臂應筆直，螺紋完整，平滑。安裝后，每個輔助支架和吊架的力應均勻，不銹鋼風管不會有明顯的變形。鍍鋅風道或空調設備可根據設計要求調整可調振動隔離，吊架的拉伸或壓縮量。

3. The screw holes of the suspension bracket are machined. The boom should be straight, with complete and smooth threads. After installation, the force on each auxiliary bracket and hanger should be uniform, and the stainless steel air duct should not have significant deformation. Galvanized air ducts or air conditioning equipment can be adjusted for adjustable vibration isolation and the amount of tension or compression of hangers according to design requirements.

鍍鋅管道加工內壁潤滑，阻力小，通風損失小，降低能耗，經濟運行成本，氣密性和密封性好，抗壓強度高。同時，良好的防火性能也是鍍鋅管道在工程中應用的常見原因之一。鍍鋅管道簡單，易于現場制造，與土木工程緊密配合，適用于非常復雜的凈化和通風工程。該產品主要應用于大型商場，寫字樓，地鐵站，大型超市，現代工廠消防排煙，空調通風，除塵通風等。

Galvanized pipeline processing inner wall lubrication, low resistance, low ventilation loss, reduced energy consumption, economic operating costs, good airtightness and sealing, high compressive strength. Meanwhile, good fire resistance is also one of the common reasons for the application of galvanized pipes in engineering. Galvanized pipes are simple, easy to manufacture on site, closely compatible with civil engineering, and suitable for very complex purification and ventilation projects. This product is mainly used in large shopping malls, office buildings, subway stations, large supermarkets, modern factories for fire exhaust, air conditioning ventilation, dust removal ventilation, etc.
