　　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(zhì)損失

　　1. Lower material losses

　　由于金屬矩形風(fēng)管薄鋼法蘭風(fēng)管一般采用計(jì)算機(jī)放樣、激光切割、水生產(chǎn)。與傳統(tǒng)的手工放樣切割相比，具有加工精度高、切削損耗小的優(yōu)點(diǎn)。

　　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(tǒng)角鋼法蘭風(fēng)管,風(fēng)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(jié)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(shù)量增加了約4%，其次是采用自動(dòng)生產(chǎn)線，生產(chǎn)精度和質(zhì)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(duì)環(huán)境的污染，具有較好的經(jīng)濟(jì)效益和社會(huì)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(xù)費(fèi)

　　3. Fees

　　生產(chǎn)金屬矩形風(fēng)管和薄鋼板法蘭風(fēng)管，工廠定制的加工成本為每平方米14元，而常規(guī)角鋼法蘭風(fēng)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(jié)省勞動(dòng)力8元左右。

　　Every square metre saves about 8 yuan of labor.

　　4. 節(jié)省工程機(jī)械成本

　　4. Save the cost of construction machinery

　　由于工廠集中定制，薄鋼法蘭風(fēng)管降低了加工機(jī)械的成本，節(jié)約了工程機(jī)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(zhì)量和工程經(jīng)濟(jì)效益三個(gè)方面可以看出，薄鋼法蘭風(fēng)管比角鋼法蘭風(fēng)管具有巨大的，我們可以根據(jù)山東風(fēng)管生產(chǎn)建設(shè)的實(shí)際情況進(jìn)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.
