Processing of ventilation pipe in Shandong Province

1、螺旋风管加工连接要求

1. Processing and connection requirements of spiral air duct

双壁螺旋风管直径<650mm采用机械法兰连接，直径≥650mm采用角钢法兰连接。

Double wall spiral air duct with diameter less than 650mm shall be connected by mechanical flange, and the diameter greater than or equal to 650mm shall be connected with angle steel flange.

单壁螺旋风管直径≤600mm采用芯管插接加自攻螺丝连接方式，直径>600mm采用角钢法兰连接。

Single wall spiral air duct with diameter less than or equal to 600mm shall be connected by core pipe plug-in and self tapping screw, and the diameter greater than 600mm shall be connected by angle steel flange.

2、济南双壁螺旋风管加工一般规定

2. Jinan double wall spiral duct processing General Provisions

中间保温层采用厚度为25mm、密度为32kg/m3的玻璃棉做保温吸声，外贴碳化无纺布。

Glass wool with a thickness of 25 mm and density of 32 kg / m3 is used as heat insulation and sound absorption layer in the middle, and carbonized non-woven fabric is pasted outside.

内层板为0.55mm厚的穿孔镀锌板，穿孔率应在百分之30以上。

The inner layer is 0.55mm thick perforated galvanized sheet, and the perforation rate shall be more than 30%.

外层螺旋风管镀锌板为热镀锌，其外层镀锌板厚度同单壁螺旋风管要求。

The galvanized sheet of outer spiral air duct is hot-dip galvanized, and its thickness is the same as that of single wall spiral cyclone tube.

3、单壁螺旋风管加工

3. Processing of single wall spiral air duct

钢带架上装好成卷的薄钢带，薄钢带通过切断与焊接机构进入压制成型工作部分，成型工作头(专用模具)使通风管道按规定的管径锁缝成形。成型螺旋管沿成品架不断加工，向前延长，移动锯根据所需尺寸截取卷好的圆形螺旋通风管。然后从成品架上卸下放成品区，按系统编好号。

The thin steel strip in coils is installed on the steel belt rack, and the thin steel strip enters the pressing forming part through the cutting and welding mechanism, and the forming working head (special mold) makes the ventilation pipe seam forming according to the specified pipe diameter. The forming spiral pipe is continuously processed along the finished product rack and extended forward. The circular spiral ventilation pipe is cut off by moving saw according to the required size. Then it is unloaded from the finished product rack to the finished product area and numbered according to the system.
