濟南鐵皮風管加工廠家提醒，規(guī)范中規(guī)定，低壓系統(tǒng)風管10米接縫不大于2個漏光點且平均每100米接縫不大于16個漏光點為合格。通過檢查大樓已施工完成的11-14層風管接縫，發(fā)現漏光點超標，存在100米接縫大于 16個漏光點。

Jinan iron sheet air duct processing manufacturer reminds that according to the regulations, it is qualified if the 10 meter joint of the low-pressure system air duct is not more than 2 leakage points, and the average joint is not more than 16 leakage points per 100 meters. By inspecting the joints of the air ducts on floors 11-14 of the completed building, it was found that the leakage points exceeded the standard, with more than 16 leakage points at 100 meter joints.

控制好接縫漏光點是保證風管系統(tǒng)工程質量的前提條件。可以減少返修，降低施工成本。風管的漏光點多，漏風量增大，從而增加了能耗，浪費了資源,增加了工程使用期間的運行成本。

Controlling joint light leakage points is a prerequisite for ensuring the quality of air duct system engineering. It can reduce rework and construction costs. There are many light leakage points in the air duct, which increases the amount of air leakage, thereby increasing energy consumption, wasting resources, and increasing the operating costs during the use of the project.

風管大邊長≤300mm時，外邊長偏差≤2mm，兩對角線長度之差≤3mm；風管大邊長＞300mm時，外邊長偏差≤3mm，兩對角線長度之差≤3mm。

When the large side length of the air duct is ≤ 300mm, the deviation of the outer side length is ≤ 2mm, and the difference between the lengths of the two diagonals is ≤ 3mm; When the large side length of the air duct is greater than 300mm, the deviation of the outer side length is ≤ 3mm, and the difference between the lengths of the two diagonals is ≤ 3mm.

1、制定標準咬口形式

1. Develop standard bite forms

2、加強現場檢查

2. Strengthen on-site inspections

改進法蘭原有的下料方法：

Improve the original flange cutting method:

1、設計簡單工具進行法蘭下料。法蘭下料的簡單工具是利用一根已經調直的10#槽鋼，在端頭處焊接一根L50*50*5的角鋼。

1. Design simple tools for flange cutting. The simple tool for flange cutting is to use a straightened 10 # channel steel and weld an L50 * 50 * 5 angle steel at the end.

2、在10#槽鋼上量取需下料尺寸，與機械切割臺調平，與切割片調垂直，固定在切割機械上。然后進行批次下料，保證下料尺寸正確統(tǒng)一(見下圖1)。

2. Measure the required cutting size on the 10 # channel steel, level it with the mechanical cutting table, align it vertically with the cutting blade, and fix it on the cutting machine. Then proceed with batch cutting to ensure correct and uniform cutting dimensions (see Figure 1).

解決法蘭焊接方法不當的問題：

Solving the problem of improper flange welding methods:

1、制作法蘭焊接模具。利用鋼板制作焊接平臺，把4~6個長50㎜的L50*5的角鋼焊接在鋼板平臺上，尺寸為所加工法蘭的尺寸，校準模具尺寸。

1. Make flange welding molds. Using steel plates to make a welding platform, weld 4-6 L50 * 5 angle steels with a length of 50 mm onto the steel plate platform, with the dimensions of the processed flanges, and calibrate the mold dimensions.

2、焊接法蘭時，必須先行點焊法蘭對角線，檢查法蘭的對角線的偏差。焊接采用對角線焊接方法，保證法蘭的平整度，成品的焊接質量。

2. When welding flanges, it is necessary to first spot weld the diagonal of the flange and check the deviation of the diagonal of the flange. The welding adopts diagonal welding method to ensure the flatness of the flange and the welding quality of the finished product.
