與傳統角鋼法蘭連接技術相比，薄鋼法蘭制造安裝技術具有技術先進、產品質量穩定、成型質量好、減少環境污染、降低作業勞動強度、加快施工進度等優點。那么薄鋼法蘭管和角法蘭管有什么區別呢?
Compared with traditional angle steel flange connection technology, thin steel flange manufacturing and installation technology has the advantages of advanced technology, stable product quality, good forming quality, reducing environmental pollution, reducing labor intensity and accelerating construction progress. So what's the difference between thin steel flange tube and corner flange tube?
1. 較低的物質損失
1. Lower material losses
由于金屬矩形風管薄鋼法蘭風管一般采用計算機放樣、激光切割、水生產。與傳統的手工放樣切割相比，具有加工精度高、切削損耗小的優點。
Because the metal rectangular air duct thin steel flange air duct generally uses computer lofting, laser cutting, water production. Compared with traditional manual lofting cutting, it has the advantages of high processing accuracy and low cutting loss.
2、保存角法蘭
2. Preserving corner flange
在傳統角鋼法蘭風管,風管如600毫米* 300毫米,通常使用∟30角3.6米* 1.37公斤* 4 = $ 20元,管占地面積1.8平方米,節省約11元每平方米。
In the traditional angle steel flanged duct, such as 600 mm * 300 mm, the duct is usually used 30 angle 3.6 m * 1.37 kg * 4 = 20 yuan, covering an area of 1.8 square meters, saving about 11 yuan per square meter.
由于法蘭是由鍍鋅鋼板制成，鍍鋅鋼板的數量增加了約4%，其次是采用自動生產線，生產精度和質量更容易控制。
Because flanges are made of galvanized steel sheets, the number of galvanized steel sheets has increased by about 4%, followed by the use of automatic production lines, the production accuracy and quality are easier to control.
此外，由于型鋼和防腐工程的減少，也減少了油漆對環境的污染，具有較好的經濟效益和社會效益。
In addition, due to the reduction of section steel and anti-corrosion engineering, it also reduces the pollution of paint to the environment, and has better economic and social benefits.
3.手續費
3. Fees
生產金屬矩形風管和薄鋼板法蘭風管，工廠定制的加工成本為每平方米14元，而常規角鋼法蘭風管的加工成本為每平方米22元左右。
Production of metal rectangular air duct and thin steel plate flange air duct, factory customized processing cost of 14 yuan per square metre, while the processing cost of conventional angle steel flange air duct is about 22 yuan per square metre.
每平方米節省勞動力8元左右。
Every square metre saves about 8 yuan of labor.
4. 節省工程機械成本
4. Save the cost of construction machinery
由于工廠集中定制，薄鋼法蘭風管降低了加工機械的成本，節約了工程機械的成本。
Because of the centralized customization of the factory, thin steel flange air duct reduces the cost of processing machinery and saves the cost of construction machinery.
因此，從施工效率、工程質量和工程經濟效益三個方面可以看出，薄鋼法蘭風管比角鋼法蘭風管具有巨大的，我們可以根據山東風管生產建設的實際情況進行選擇。
Therefore, from the three aspects of construction efficiency, engineering quality and engineering economic benefits, it can be seen that thin steel flange air duct has great advantages over angle steel flange air duct. We can choose according to the actual situation of Shandong air duct production and construction.
