1、先鐵皮風(fēng)管所用的材料應(yīng)具有導(dǎo)熱性小、保溫，耐腐蝕、耐火等性能。

1. The materials used for the iron sheet air duct should have low thermal conductivity, insulation, corrosion resistance, fire resistance, and other properties.

2、管道設(shè)不宜太長，在可能條件下管徑要粗，式樣以圓形為佳。

2. When designing pipelines, it is not advisable to be too long. When possible, the diameter of the pipeline should be thick, and the design should be circular.

3、支管的半徑不得小于主管半徑的1/2-1/3，便于通風(fēng)管道加工。

3. The radius of the branch pipe shall not be less than 1/2-1/3 of the radius of the main pipe to facilitate the processing of ventilation ducts.

4、鐵皮風(fēng)管設(shè)彎曲的角度要盡量呈弧形。

4. When designing iron sheet air ducts, the bending angle should be as curved as possible.

5、設(shè)管道的彎頭要盡量少，兩個彎頭的距離要大些。當(dāng)兩個彎頭的距離為管徑的3倍時，阻力大約增加80%；若為5倍時，則僅增加30%。

5. When designing pipelines, the number of bends should be minimized and the distance between the two bends should be larger. When the distance between two elbows is three times the pipe diameter, the resistance increases by approximately 80%; If it is 5 times, it will only increase by 30%.

6、盡量直立或傾斜放置，設(shè)置清掃口，連接部分應(yīng)嚴(yán)密不漏氣，并便于檢修。

6. Try to place it upright or tilted as much as possible, set up cleaning ports, and ensure that the connecting parts are tight, airtight, and easy to maintain.

此外鐵皮風(fēng)管加工的鋪設(shè)對于周圍環(huán)境也是有要求的，環(huán)境的把握對于管道的使用是其決定作用的，接下來濟(jì)南鐵皮風(fēng)管加工廠家的分享會在以后的使用中可以參考到。

In addition, the laying of iron sheet air duct processing also has requirements for the surrounding environment, and the grasp of the environment plays a decisive role in the use of the pipeline. The sharing of Jinan iron sheet air duct processing manufacturers can be referred to in future use.

1、制作地點(diǎn)要有相應(yīng)的加工工藝的必備工具、設(shè)施及電源和可靠的防護(hù)裝置，并有消防器材。這是我們鋪設(shè)管道必須的要求。

1. The production site should have the necessary tools, facilities, power supply, reliable safety protection devices, and fire-fighting equipment for the corresponding processing technology. This is a necessary requirement for us to lay pipelines.

2、地點(diǎn)處理明確，就是鐵皮風(fēng)管的制作應(yīng)有批準(zhǔn)的圖紙，經(jīng)審查的大樣圖，系統(tǒng)圖，并有施工員書面的技術(shù)質(zhì)量及交底。

2. The location handling is clear, which means that the production of iron sheet air ducts should have approved drawings, reviewed detailed drawings, system diagrams, and written technical quality and safety disclosures from the construction personnel.

3、對整體的環(huán)境進(jìn)行處理，集中加工應(yīng)具有寬敞、明亮、潔凈、地面平整、不潮濕的廠房。

3. To handle the overall environment, centralized processing should have a spacious, bright, clean, flat ground, and non humid factory building.
