要知道镀锌风管的锌镀层经钝化处理、染色或涂覆护光剂后，能提高其防护性和装饰性。并且镀锌风管的防火性能主要体现在，它具有不燃性，但是有一点需要注意的是，它的保温层是否燃烧要依材质而定，我们建议镀锌风管的材质要选用离心玻璃棉等不燃保温材料。

It should be noted that the zinc coating of galvanized air ducts can improve their protective and decorative properties after passivation treatment, dyeing, or coating with protective agents. And the fire resistance performance of galvanized air ducts is mainly reflected in their non flammability. However, it should be noted that whether the insulation layer burns depends on the material. We suggest using non combustible insulation materials such as centrifugal glass wool for galvanized air ducts.

镀锌风管是早使用的风管之一，采用镀锌薄钢板制作，有不易生锈，保温和消声功能，不锈钢风管制作安装周期长的特点。镀锌风管适合含湿量小的一般性气体的输送。

Galvanized air duct is one of the early used air ducts, made of galvanized thin steel plate, which is not easy to rust, has insulation and noise reduction functions, and has the characteristics of long installation cycle for stainless steel air ducts. Galvanized air ducts are suitable for conveying general gases with low moisture content.

对于镀锌风管来说，它凭借其良好的防火性能能很好的应用于净化系统送回风管、空调通风管、工业送排风通风管、系统吸排风管、矿用抽放瓦斯管、矿用涂胶布风筒等众多场合。

For galvanized air ducts, they can be well applied in many occasions such as purification system return air ducts, central air conditioning ventilation ducts, industrial supply and exhaust ventilation ducts, environmental protection system suction and exhaust ducts, mining gas drainage pipes, mining coated fabric air ducts, etc. due to their good fire resistance performance.

镀锌风管安装简单，现场制做方便，与土建工程配合紧密，能适合非常复杂的净化通风工程。

Galvanized air ducts are easy to install, easy to manufacture on site, and closely coordinated with civil engineering, making them suitable for very complex purification and ventilation projects.

产品多用于大型、写字楼、地铁站、大型、现代化工厂的消防排烟、空调通风、排尘通风等。济南不锈钢风管具有内外壁光滑，风道阻力小，送排风时不产生二次噪声，降低能耗，节约运行费用等优点，为此它得到了广大用户的认可，那么我们要给大家整理介绍一下有关于镀锌板风管在安装过程中应该注意的问题，下面跟我们来具体了解一下，如下：

The product is mainly used for fire smoke exhaust, air conditioning ventilation, dust exhaust ventilation, etc. in large shopping malls, office buildings, subway stations, large supermarkets, and modern chemical plants. Jinan stainless steel air duct has advantages such as smooth inner and outer walls, low air duct resistance, no secondary noise during air supply and exhaust, reduced energy consumption, and reduced operating costs. Therefore, it has been recognized by a large number of users. Therefore, we would like to summarize and introduce some issues that should be paid attention to during the installation process of galvanized sheet air ducts. Let's take a closer look, as follows:

注意一、镀锌板风管水平安装 ，直径或长边尺寸小于等于400mm，间距不应大于4m；大于400mm，济南不锈钢风管不应大于3m。镀锌板风管的支、吊架间距可分别延长5m和3.75m；对于薄钢板法兰的镀锌板风管，其支、吊架间距不应大于3m。

Note 1: Galvanized sheet air ducts should be installed horizontally, with a diameter or length of 400mm or less and a spacing of no more than 4m; If it is greater than 400mm, the stainless steel air duct in Jinan should not exceed 3m. The spacing between the supports and hangers of galvanized sheet air ducts can be extended to 5m and 3.75m respectively; For galvanized sheet air ducts with thin steel plate flanges, the spacing between supports and hangers should not exceed 3 meters.

注意二、镀锌板风管垂直安装，间距不应大于4m，单根直管少应有2个固定点。

Note 2: Galvanized sheet air ducts should be installed vertically with a spacing of no more than 4m, and a single straight pipe should have at least 2 fixing points.

注意三、镀锌板风管支、吊架宜按国标图集与规范选用强度和刚度相适应的形式和规格。对于直径或边长大于2500mm的超宽、超重等镀锌板风管的支、吊架应按设计规定。

Note 3: Galvanized sheet air duct supports and hangers should be selected in a form and specification that is suitable for strength and stiffness according to the national standard atlas and specifications. The support and hanger of galvanized sheet air ducts with a diameter or side length greater than 2500mm, such as ultra wide and overweight, should be in accordance with the design specifications.
