How much do you know about Shandong ventilation pipeline processing? With the continuous promotion of its application scope, more and more people choose to install the equipment. What matters do you need to know about the installation and connection of the air duct? Do you know? Next, Shandong ventilation pipeline processing equipment will be introduced below, hoping to help you.

山東通風管道加工

Processing of ventilation pipe in Shandong Province

1、螺旋風管加工連接要求

1. Processing and connection requirements of spiral air duct

雙壁螺旋風管直徑<650mm采用機械法蘭連接，直徑≥650mm采用角鋼法蘭連接。

Double wall spiral 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.

單壁螺旋風管直徑≤600mm采用芯管插接加自攻螺絲連接方式，直徑>600mm采用角鋼法蘭連接。

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、濟南雙壁螺旋風管加工一般規(guī)定

2. Jinan double wall spiral duct processing General Provisions

中間保溫層采用厚度為25mm、密度為32kg/m3的玻璃棉做保溫吸聲，外貼碳化無紡布。

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.

內層板為0.55mm厚的穿孔鍍鋅板，穿孔率應在百分之30以上。

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

外層螺旋風管鍍鋅板為熱鍍鋅，其外層鍍鋅板厚度同單壁螺旋風管要求。

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、單壁螺旋風管加工

3. Processing of single wall spiral air duct

鋼帶架上裝好成卷的薄鋼帶，薄鋼帶通過切斷與焊接機構進入壓制成型工作部分，成型工作頭(專用模具)使通風管道按規(guī)定的管徑鎖縫成形。成型螺旋管沿成品架不斷加工，向前延長，移動鋸根據(jù)所需尺寸截取卷好的圓形螺旋通風管。然后從成品架上卸下放成品區(qū)，按系統(tǒng)編好號。

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.
