要知道鍍鋅風(fēng)管的鋅鍍層經(jīng)鈍化處理、染色或涂覆護(hù)光劑后，能提高其防護(hù)性和裝飾性。并且鍍鋅風(fēng)管的防火性能主要體現(xiàn)在，它具有不燃性，但是有一點(diǎn)需要注意的是，它的保溫層是否燃燒要依材質(zhì)而定，我們建議鍍鋅風(fēng)管的材質(zhì)要選用離心玻璃棉等不燃保溫材料。

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.

鍍鋅風(fēng)管是早使用的風(fēng)管之一，采用鍍鋅薄鋼板制作，有不易生銹，保溫和消聲功能，不銹鋼風(fēng)管制作安裝周期長(zhǎng)的特點(diǎn)。鍍鋅風(fēng)管適合含濕量小的一般性氣體的輸送。

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.

對(duì)于鍍鋅風(fēng)管來說，它憑借其良好的防火性能能很好的應(yīng)用于凈化系統(tǒng)送回風(fēng)管、中央空調(diào)通風(fēng)管、工業(yè)送排風(fēng)通風(fēng)管、環(huán)保系統(tǒng)吸排風(fēng)管、礦用抽放瓦斯管、礦用涂膠布風(fēng)筒等眾多場(chǎng)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.

鍍鋅風(fēng)管安裝簡(jiǎn)單，現(xiàn)場(chǎng)制做方便，與土建工程配合緊密，能適合非常復(fù)雜的凈化通風(fēng)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.

產(chǎn)品多用于大型商場(chǎng)、寫字樓、地鐵站、大型超市、現(xiàn)代化工廠的消防排煙、空調(diào)通風(fēng)、排塵通風(fēng)等。濟(jì)南不銹鋼風(fēng)管具有內(nèi)外壁光滑，風(fēng)道阻力小，送排風(fēng)時(shí)不產(chǎn)生二次噪聲，降低能耗，節(jié)約運(yùn)行費(fèi)用等優(yōu)點(diǎn)，為此它得到了廣大用戶的認(rèn)可，那么我們要給大家整理介紹一下有關(guān)于鍍鋅板風(fēng)管在安裝過程中應(yīng)該注意的問題，下面跟我們來具體了解一下，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、鍍鋅板風(fēng)管水平安裝 ，直徑或長(zhǎng)邊尺寸小于等于400mm，間距不應(yīng)大于4m；大于400mm，濟(jì)南不銹鋼風(fēng)管不應(yīng)大于3m。鍍鋅板風(fēng)管的支、吊架間距可分別延長(zhǎng)至5m和3.75m；對(duì)于薄鋼板法蘭的鍍鋅板風(fēng)管，其支、吊架間距不應(yīng)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、鍍鋅板風(fēng)管垂直安裝，間距不應(yīng)大于4m，單根直管至少應(yīng)有2個(gè)固定點(diǎn)。

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、鍍鋅板風(fēng)管支、吊架宜按國(guó)標(biāo)圖集與規(guī)范選用強(qiáng)度和剛度相適應(yīng)的形式和規(guī)格。對(duì)于直徑或邊長(zhǎng)大于2500mm的超寬、超重等鍍鋅板風(fēng)管的支、吊架應(yīng)按設(shè)計(jì)規(guī)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.
