Flange plate duct is characterized from a flange, reducing duct weight, good sealing performance, appearance, high intensity total budget duct board, quick and easy installation, low cost of production. The use of flange plate duct processing pipeline not only produced by a conventional duct inefficient human labor becomes efficient machinery production, greatly reduce the labor intensity and improve work efficiency and reduce the cost of the project. By comparison with the angle flange wind pipe, each 10 square meters for production and installation of the wind, in the same period the case of co-duct board specifications, can save about 60% of the labor force, all kinds of steel 30 kg, various bolted 10 More than sets, rust 0.2 kg; Duct flange made of galvanized steel production, the amount of galvanized steel increased by approximately 4%; with the production line, the production of precision and quality is easier to control. In addition, the steel and reduce the amount of corrosion engineering, reducing the paint pollution of the environment, with good economic and social benefits. Flange plate Method 1. Features Duct production line mechanization, high degree of automation, greatly improving production efficiency and manufacturing precision duct, reduce project cost; 2. air duct from a flange, to reduce the weight of the wind, with the traditional Comparison of angle iron flanges, saving a total of flange bolts and steel duct board offer, reduce material loss; 3. duct sealing, duct board altogether, significantly reducing the amount of air leakage, save energy and reduce the host operating costs; 4 . Duct automatic beading, high strength and appearance is clean and free zinc coating damage; 5. produce quick installation, reduce labor intensity and improve labor efficiency to meet modern engineering needs, improve competitive advantage to install the unit. Applications way flange plate duct work and living environment as a guarantee air quality, technical measures to prevent contamination of the indoor environment should be given priority. It works is that the total of flange plate duct using local stream, so that the local site is not contaminated hazardous materials, causing a good air environment. Flange plate duct into the local supply and local exhaust two categories. Local exhaust pollutants are trapped in place, after purifying exhaust to the outdoors. Local air is treated, in line with the requirements of air to the local work place, to ensure that air condition the local area. The main contribution of: flange plate duct in indoor air is approximately piston-like flow, so that the gas flow with the narrow room at the top of pollutants discharged from a total budget of duct board, spread flat glass steel flange plate duct (certification) total duct board by Wu Teng County 庄传平 glass steel working place.
