　　Ventilation pipes are very common in our daily life. They can be seen not only in the construction industry and our office space, but also in Jinan. What are the key points to be clear when installing the air pipes for processing? Are you not clear? Next, follow the ventilation pipe processing plant to understand the following situation, hoping to help you.

　　下面就來介紹一下風管加工的一些規定，如下:

　　Here are some regulations on air duct processing, as follows:

　　1、螺桿風管加工及連接要求

　　1. Processing and connection requirements of screw air duct

　　雙壁螺旋管道直徑<650mm采用機械法蘭連接，直徑≥650mm采用角鋼法蘭連接。

　　Double wall spiral pipe with diameter less than 650mm shall be connected by mechanical flange, and angle steel flange shall be used for connection with diameter more than 650mm.

　　單壁螺旋風道直徑≤600mm采用芯管插入自攻螺釘連接方式，>600mm直徑采用角鋼法蘭連接方式。

　　The single wall spiral air duct with diameter ≤ 600mm is connected by inserting the core pipe into the self tapping screw, and the diameter > 600mm is connected by angle steel flange.

　　2、濟南雙壁螺旋風管加工總則

　　2. General rules for processing of Jinan double wall spiral air duct

　　中間保溫層為玻璃棉，厚度25mm，密度32kg/m3，用于隔音，外覆碳化無紡布。內板為0.55mm厚的打孔鍍鋅板，打孔率在30%以上。外螺旋槽鍍鋅板為熱鍍鋅，外螺旋槽鍍鋅板厚度與單壁螺旋槽相同。

　　The intermediate insulating layer is glass wool, with thickness of 25mm and density of 32kg / m3, which is used for sound insulation and covered with carbonized non-woven fabric. The inner plate is a 0.55mm-thick perforated galvanized plate with a perforation rate of more than 30%. The galvanized sheet of the outer spiral groove is hot-dip galvanized, and the thickness of the galvanized sheet of the outer spiral groove is the same as that of the single wall spiral groove.

　　3.單壁螺旋風道加工

　　3. Processing of single wall spiral air duct

　　鋼帶框架上設有軋制薄鋼帶，薄鋼帶通過切割和焊接機構進入沖壓成形工作部位，成形工作頭(專用模具)根據規定管徑鎖接使通風管道成形。

　　The steel strip frame is equipped with rolled thin steel strip, which enters the stamping working position through cutting and welding mechanism, and the forming working head (special mold) is locked according to the specified pipe diameter to form the ventilation pipe.

　　成形螺旋管沿成品機架連續加工，并向前延伸。動鋸按要求尺寸截留卷好的圓形螺旋通風管道。然后根據系統編號從成品架上卸下到成品區。

　　The forming spiral tube is continuously processed along the finished frame and extends forward. The circular spiral ventilation pipe is retained by the movable saw according to the required size. Then, according to the system number, it is unloaded from the finished product rack to the finished product area.

　　4. 風道在地面預裝好后安裝在高蹺上時，預裝長度的限制是為了保護風道不因自重引起的彎曲而損壞構件界面。

　　4. When the air duct is installed on stilts after preassembled on the ground, the limit of preassembled length is to protect the air duct from damaging the component interface due to bending caused by self weight.

　　5、垂直安裝的通風管軸,因為空間更少,而不是未來維護方便,所以風管道通常用于外套角鋼法蘭連接到連接的松緊度和強度增加,凸緣成“好”的形狀,掛條直接掛在角鋼法蘭吊耳沒有額外的支持。

　　5. Due to less space, rather than convenient maintenance in the future, the vertical installation of the ventilation pipe shaft is usually used to increase the tightness and strength of the outer angle steel flange connection, the flange is in a "good" shape, and the hanging bar is directly hung on the angle steel flange lug without additional support.

　　6. 玻璃鋼復合板風道端為切割面時，在裝配法蘭接頭前，應先用膠帶或膠水將管端切割面密封，以防止玻璃鋼暴露和分散。

　　6. When the air duct end of FRP composite plate is the cutting surface, the cutting surface of the pipe end shall be sealed with tape or glue before assembling the flange joint to prevent the exposure and dispersion of FRP.

　　上面安裝濟南管加工廠的介紹通風管道加工應該清楚六,我相信你有一個進一步的了解管道在閱讀上面的內容,我希望這些內容可以幫助你,想知道更多的細節,可以更加關注網站動態。

　　The above installation of Jinan pipe processing plant should be clear six, I believe you have a further understanding of the pipe in reading the above content, I hope these content can help you, want to know more details, can pay more attention to the website dynamic.
