Total panel using flange say again without using flange, make the form of rectangular ducts than traditional processing speed faster and more convenient and more small leakage rate. Its advantage is to save material, reducing engineering investment, Leakage air volume is small, reduce the energy consumption and save the operation cost, construction enterprises. American and European and other developed countries since 1990s without using duct flange, the technology has been widely applied in all kinds of engineering. China's national standards GB50243-2002 about the ventilation and air conditioning project construction and acceptance standard specified rectangular ducts can use without flange connection process. Beijing wangfujing CTS buildings, hotels, guangzhou synthetic exploitation of machine manufacturing Co., LTD adopts project without the flange connection, the effect is good. This production line production of stainless steel, galvanized duct its connection form usable plug-and-socket or Angle can be pressed directly with flanges and a duct &joint forming. Advanced technology, produce duct baiting accurate, low consumption materials, stable product quality, variety, smooth lines, far below the national standard of air leakage of ventilation pipe, the production scale, standardization, present factory automation
