专注通风管道加工·排烟罩

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.

正是由于镀锌风管的优势突出，被越来越多的行业应用起来，同时市场的需求量也是日趋升高。对于大多数客户而言，镀锌风管一般需要按照实际情况设计定制，那么，为什么这么多的客户会选择定制镀锌风管呢？

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?

优势一：更吻合。一般是测量好尺寸大小，安装位置，用途之后，就为客户量身定制合适的解决方案，设计出实用又合理的方案。镀锌风管厂家一般会根据客户的需求定制出适合的而方案。

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.

优势二：材质上乘。镀锌风管厂家会在源头上把控好相关材料。这样在定制加工缓解才能事半功倍，只需要按照不太尺寸定制出经久耐用的产品，同时还能达到的要求。

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.

优势三：性能稳定。镀锌风管定制出厂以后洁净效果非常好。同时凡是达到一定的强度等级后还有良好的防火特性。

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，正是由于镀锌风管有如此多的优势，尤其是能满足不同地区、不同用途的需要，所以，镀锌风管常常用作除尘、排烟、排风中，但是安装时记得不要放在出风口哦。而且镀锌风管摩擦阻力小，输送能力高，镀锌风管管内表面非常光滑，糙率系数小，水利系数可长期保持在145-150范围内，经测试得到其水流摩阻损失系数为0.000915，能显着减少沿程的流体压力损失，提高输送能力20%以上。同时，镀锌风管具有很强的耐腐蚀性，镀锌风管能够抵抗酸、碱、盐、海水、未经处理的污水、腐蚀性土壤或地下水及众多化学流体的腐蚀。镀锌风管的耐热抗冻性好，镀锌风管的温度使用范围一般在－40℃～80℃之间，若先用特殊树脂其使用温度可达到更高。

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.
