Galvanized air duct is a very common kind of ventilation duct in our life. It is generally used in the air supply, exhaust and smoke exhaust duct works of hotels, shopping malls, textiles, chemical fibers, petrochemical, machinery manufacturing, instruments, electronics, medicine, tobacco, food, medical treatment, storage, office buildings, subway, civil air defense, basement and other projects. Galvanized air duct is also widely used in factory workshops, which is a special dust removal device in factories.

正是由于鍍鋅風管的優勢突出，被越來越多的行業應用起來，同時市場的需求量也是日趨升高。對于大多數客戶而言，鍍鋅風管一般需要按照實際情況設計定制，那么，為什么這么多的客戶會選擇定制鍍鋅風管呢？

It is precisely because of the outstanding advantages of galvanized air duct that it is applied in more and more industries, and the market demand is also increasing. For most customers, galvanized air duct generally needs to be designed and customized according to the actual situation, so why do so many customers choose to customize galvanized air duct?

優勢一：更吻合。一般是測量好尺寸大小，安裝位置，用途之后，就為客戶量身定制合適的解決方案，設計出實用又合理的方案。鍍鋅風管廠家一般會根據客戶的需求定制出適合的而方案。

Advantage 1: more consistent. Generally, after measuring the size, installation position and purpose, we will customize appropriate solutions for customers and design practical and reasonable solutions. Galvanized air duct manufacturers will generally customize appropriate solutions according to customer needs.

優勢二：材質上乘。鍍鋅風管廠家會在源頭上把控好相關材料。這樣在定制加工緩解才能事半功倍，只需要按照不太尺寸定制出經久耐用的產品，同時還能達到的要求。

Advantage 2: superior material. The manufacturer of galvanized air duct will control relevant materials at the source. In this way, we can get twice the result with half the effort in customized processing. We only need to customize durable products according to less size, and at the same time, we can meet the requirements of environmental protection.

優勢三：性能穩定。鍍鋅風管定制出廠以后潔凈效果非常好。同時凡是達到一定的強度等級后還有良好的防火特性。

Advantage 3: Stable performance. The customized galvanized air duct has a very good cleaning effect after leaving the factory. At the same time, after reaching a certain strength level, there are good fire resistance characteristics.

所以，正是由于鍍鋅風管有如此多的優勢，尤其是能滿足不同地區、不同用途的需要，所以，鍍鋅風管常常用作除塵、排煙、排風中，但是安裝時記得不要放在出風口哦。而且鍍鋅風管摩擦阻力小，輸送能力高，鍍鋅風管管內表面非常光滑，糙率系數小，水利系數可長期保持在145-150范圍內，經測試得到其水流摩阻損失系數為0.000915，能顯著減少沿程的流體壓力損失，提高輸送能力20%以上。同時，鍍鋅風管具有很強的耐腐蝕性，鍍鋅風管能夠抵抗酸、堿、鹽、海水、未經處理的污水、腐蝕性土壤或地下水及眾多化學流體的腐蝕。鍍鋅風管的耐熱抗凍性好，鍍鋅風管的溫度使用范圍一般在－40℃～80℃之間，若先用特殊樹脂其使用溫度可達到更高。

Therefore, it is precisely because the galvanized air duct has so many advantages, especially to meet the needs of different regions and different purposes, so the galvanized air duct is often used for dust removal, smoke exhaust and air exhaust, but remember not to put it at the air outlet when installing. In addition, the galvanized air duct has low friction resistance and high transmission capacity. The inner surface of the galvanized air duct is very smooth, and the roughness coefficient is small. The hydraulic coefficient can be kept in the range of 145-150 for a long time. The water flow friction loss coefficient is 0.000915 according to the test, which can significantly reduce the fluid pressure loss along the way and improve the transmission capacity by more than 20%. At the same time, galvanized air duct has strong corrosion resistance, which can resist the corrosion of acid, alkali, salt, seawater, untreated sewage, corrosive soil or groundwater and many chemical fluids. Galvanized air duct has good heat resistance and frost resistance. The temperature range of galvanized air duct is generally - 40 ℃~80 ℃. If special resin is used first, the temperature can reach higher.
