1. Select 5 flange seals mm or 8501 fire-resistant sealing strips.

2.具有諸如中性玻璃膠等密封劑的鍍鋅風管咬合縫、鉚釘縫、法蘭反側四角等間隙。在涂上封口液之前，要先把表面的污垢和油污清理干凈。

2. Gaps such as seam, rivet seam, and four corners on the opposite side of flange of galvanized air duct with sealant such as neutral glass glue. Before applying sealing fluid, the dirt and oil stain on the surface shall be cleaned up.

3.法蘭絲孔和鉚釘孔距不得大于100毫米。矩形法蘭的四邊角要有螺紋。彎頭、三通等管子的排水管采用扁頭鉚接，風機通風管道禁止使用抽芯鉚接，把密封膠涂在鉚釘上。

3. The distance between flange screw hole and rivet hole shall not be greater than 100mm. The four corners of rectangular flange shall be threaded. The drain pipes of elbows, tees and other pipes shall be riveted with flat heads. The fan ventilation pipes shall not be riveted with loose core, and the sealant shall be applied to the rivets.

4.在法蘭上安裝鍍鋅風管時，其反面平整并緊靠法蘭，其寬度不得小于7毫米。

4. When installing galvanized air duct on the flange, its reverse side shall be flat and close to the flange, and its width shall not be less than 7 mm.

5.采用角鋼法蘭連接軟管。

5. Use angle steel flange to connect the hose.

6.采用帶角鋼的鍍鋅風管。

6. Galvanized air duct with angle steel shall be adopted.

7.鍍鋅風管的咬合形式是單一的咬合和配合的角咬合。

7. The occlusion form of galvanized air duct is single occlusion and matched angular occlusion.

8.在制作鍍鋅風管時，應盡可能地減少垂直直縫和不水平接縫。圓周小于或等于900 mm的底板不得有接縫，超過900 mm無橫向接縫。

8. When making galvanized air duct, vertical straight joints and non horizontal joints shall be reduced as much as possible. Baseplates with a circumference less than or equal to 900 mm shall not have joints, and those with a circumference greater than 900 mm shall not have transverse joints.

9.在板料大小符合切割要求且損失不大的情況下，可將彎頭、三通等附件與直線段進行聯接，以減小通風管道阻力。

9. When the size of the sheet meets the cutting requirements and the loss is small, the elbow, tee and other accessories can be connected with the straight section to reduce the resistance of the ventilation pipe.

本產品主要應用于工業及工程建筑，適用于工業、各種空調及通風系統的施工，適用于食品、機械、醫藥、電子、商場、體育娛樂、酒店、酒店、商場、辦公樓、、別墅、航天航空制造等行業。特別是消防通風管道工程及民用建筑的通風、通風工程及工業。

This product is mainly used in industrial and engineering buildings, applicable to the construction of industrial and various air conditioning and ventilation systems, and applicable to food, machinery, medicine, electronics, shopping malls, sports and entertainment, hotels, hotels, shopping malls, office buildings, government agencies, villas, aerospace manufacturing and other industries. In particular, fire ventilation pipeline engineering and civil building ventilation, ventilation engineering and industry.

在各種通風條件下，鍍鋅風管具有的韌性和不脆性，是其優點之一。由于長時間的風吹雨打，一些數據會變得老化、腐爛、侵蝕。鍍鋅板風管的鍍鋅保護管道鐵板不被氧化。

Under various ventilation conditions, galvanized air duct has excellent toughness and non brittleness, which is one of its advantages. Due to long-term wind and rain, some data will become aged, rotten and eroded. Galvanizing of galvanized sheet air duct protects the iron sheet of the pipe from oxidation.

鍍鋅管道內壁潤滑，阻力小，通風損失小，能耗低，經濟運行費用高，密封性好，抗壓強度高。另外，在實際工程中，使用鍍鋅管道的一個普遍原因是其耐火性能良好。鍍鋅管線結構簡單，施工方便，與土建工程密切結合，特別適合于各種復雜的凈化及通風工程。該產品廣泛應用于商場，辦公樓，地鐵入口，大型商場，現代工廠消防排煙，空調通風，除塵等。

The inner wall of galvanized pipe is lubricated, with small resistance, small ventilation loss, low energy consumption, high economic operation cost, good sealing and high compressive strength. In addition, in practical projects, a common reason for the use of galvanized pipes is their good fire resistance. Galvanized pipeline is simple in structure and convenient in construction. It is closely combined with civil engineering, especially suitable for various complex purification and ventilation projects. This product is widely used in shopping malls, office buildings, subway entrances, large shopping malls, modern factories, fire control smoke exhaust, air conditioning ventilation, dust removal, etc.
