　　什么是通風管道?

　　What is a ventilation duct?

　　通風管道是工業(yè)與民用建筑的通風與空調工程用金屬或復合管道，是為了使空氣流通，降低有害氣體濃度的一種市政基礎設施。

　　Ventilation pipe is a kind of metal or composite pipe used in ventilation and air conditioning engineering of industrial and civil buildings. It is a kind of municipal infrastructure to make the air circulate and reduce the concentration of harmful gases.

　　通風管道中的風管制作與安裝所用板材、型材以及其他主要成品材料，應符合設計及相關產品現(xiàn)行標準的規(guī)定，并應用出廠檢驗合格證明，材料進場時應按現(xiàn)行有關標準進行驗收。

　　The plates, profiles and other main finished materials used for the production and installation of air ducts in the ventilation ducts shall comply with the provisions of the current national standards for design and related products, and the factory inspection certificate shall be applied. The materials shall be accepted according to the current relevant national standards when entering the site.

　　通風管道用途分類

　　Application classification of ventilation pipe

　　一般有：凈化系統(tǒng)送回風管、空調通風管、工業(yè)送排風通風管、系統(tǒng)吸排風管、礦用抽放瓦斯管、礦用涂膠布風筒等；

　　Generally, there are: purification system air supply and return pipe, central air conditioning ventilation pipe, industrial air supply and exhaust ventilation pipe, environmental protection system air suction and exhaust pipe, mine gas drainage pipe, mine rubber coated cloth air duct, etc;

　　通風管道形狀分類

　　Shape classification of ventilation duct

　　一般有：圓形、矩形、螺旋形等；

　　Generally: round, rectangular, spiral, etc;

　　通風管道加工工藝

　　Processing technology of ventilation pipe

　　可分為角鐵法蘭風管，共板法蘭風管。

　　It can be divided into angle iron flange air pipe and common plate flange air pipe.
