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.

　　下面就来介绍一下风管加工的一些规定，如下:

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

　　1、螺杆风管加工及连接要求

　　1. Processing and connection requirements of screw air duct

　　双壁螺旋管道直径<650mm采用机械法兰连接，直径≥650mm采用角钢法兰连接。

　　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.

　　单壁螺旋风道直径≤600mm采用芯管插入自攻螺钉连接方式，>600mm直径采用角钢法兰连接方式。

　　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、济南双壁螺旋风管加工总则

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

　　中间保温层为玻璃棉，厚度25mm，密度32kg/m3，用于隔音，外覆碳化无纺布。内板为0.55mm厚的打孔镀锌板，打孔率在30%以上。外螺旋槽镀锌板为热镀锌，外螺旋槽镀锌板厚度与单壁螺旋槽相同。

　　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.单壁螺旋风道加工

　　3. Processing of single wall spiral air duct

　　钢带框架上设有轧制薄钢带，薄钢带通过切割和焊接机构进入冲压成形工作部位，成形工作头(专用模具)根据规定管径锁接使通风管道成形。

　　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.

　　成形螺旋管沿成品机架连续加工，并向前延伸。动锯按要求尺寸截留卷好的圆形螺旋通风管道。然后根据系统编号从成品架上卸下到成品区。

　　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. 风道在地面预装好后安装在高跷上时，预装长度的限制是为了保护风道不因自重引起的弯曲而损坏构件界面。

　　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、垂直安装的通风管轴,因为空间更少,而不是未来维护方便,所以风管道通常用于外套角钢法兰连接到连接的松紧度和强度增加,凸缘成“好”的形状,挂条直接挂在角钢法兰吊耳没有额外的支持。

　　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. 玻璃钢复合板风道端为切割面时，在装配法兰接头前，应先用胶带或胶水将管端切割面密封，以防止玻璃钢暴露和分散。

　　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.

　　上面安装济南管加工厂的介绍通风管道加工应该清楚六,我相信你有一个进一步的了解管道在阅读上面的内容,我希望这些内容可以帮助你,想知道更多的细节,可以更加关注网站动态。

　　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.
