　　The body, structure, fixed data, sealing data and flexible joints of smoke exhaust pipes need to be manufactured with non-combustible data.

　　當吊頂內有可燃物時，吊頂內的排煙管道應選用不焚燒資料進行隔熱，并應與可燃物堅持不小于150mm的間隔。

　　When there are combustibles in the ceiling, the smoke exhaust pipe in the ceiling should be insulated by non-incineration data, and should be not less than 150 mm apart from the combustibles.

　　2)正壓送風管道

　　2) Positive Pressure Air Supply Pipeline

　　送風管道應選用不焚燒資料制造，當選用金屬風道時，管道風速不該大于20m/s;當選用內外表光滑的混凝土等非金屬資料風道時，不該大于15m/s.

　　The air supply pipeline should be manufactured with non-incineration data. When the metal duct is selected, the wind speed of the pipeline should not be greater than 20m/s, and when the non-metallic material duct such as smooth concrete with inner and outer surfaces is selected, it should not be greater than 15m/s.

　　當加壓送風管穿越有火災可能的區域時，風管的耐火極限應不小于1h.

　　When the pressurized air duct passes through the area where fire is possible, the fire resistance limit of the air duct should not be less than 1 h.

　　送風井道應選用耐火極限不小于lh的隔墻與相鄰部位分隔，當墻上有必要設置檢修門時應選用丙級防火門。

　　The partition wall with fire resistance limit not less than LH should be selected to separate the air supply shaft from the adjacent parts. When it is necessary to install overhaul doors on the wall, class C fire doors should be selected.

　　3)通風空調

　　3) Ventilation and air conditioning

　　通風空調體系的管道等應選用不燃資料制造。

　　Ventilation and air conditioning system pipes should be manufactured with non-combustible materials.

　　觸摸腐蝕性介質的風管和柔性接頭，可選用難燃資料制造。

　　Touch the air duct and flexible joint of corrosive medium, and choose non-flammable material to manufacture.

　　復合資料風管的覆面資料有必要為不燃資料，內部的絕熱資料應為不燃或難燃B1級，且對人體無害的資料。

　　It is necessary for the cover data of composite data duct to be non-flammable. The internal insulation data should be non-flammable or non-flammable grade B1, and harmless to human body.

　　4)保溫消聲資料

　　4) Data of heat preservation and noise attenuation

　　管道和設備的保溫資料，消聲資料和粘結劑應為不焚燒資料或難焚燒資料。

　　The insulation data, noise attenuation data and binders of pipelines and equipment shall be non-incineration data or refractory data.

　　甲乙類廠房、倉庫、高層工業建筑以及影劇院、體育館等公共建筑的采暖及空調管道和設備，其保溫資料應選用不燃資料。

　　Heating and air-conditioning pipes and equipment for class A and B factories, warehouses, high-rise industrial buildings, cinemas, gymnasiums and other public buildings shall be provided with non-combustible insulation materials.

　　關于排煙管道的制造和裝置有什么要求?

　　What are the requirements for the manufacture and installation of smoke exhaust pipes?

　　1)風管水平裝置，其直徑或長邊尺度小于400mm時，距離不該大于4m;大于或等于400mm時，距離不該小于3m;

　　1) The distance should not be greater than 4 m when the diameter or length of the horizontal device is less than 400 mm, or less than 3 m when the diameter or length of the horizontal device is greater than or equal to 400 mm.

　　2)風管筆直裝置，距離不該大于4m，但每根立管的固定件不該少于2個。

　　2) The air duct should be straight, and the distance should not be greater than 4m, but the fixed parts of each riser should not be less than 2.

　　2.機械防排煙體系的矩形風道的接縫應選用咬口方式，接縫處須堅持密封。

　　2. The joint of rectangular air duct of mechanical smoke control and exhaust system should be sealed by biting method.

　　3.送風、排煙管道的單位面積答應漏風量應契合《通風與空調工程施工質量檢驗標準》GB50243中的規則。送風管道答應漏風量應根據工作壓力斷定;排煙管道均按中壓體系的規則。

　　3. The allowable air leakage per unit area of air supply and smoke exhaust pipes should conform to the rules of "Quality Inspection Standard for Ventilation and Air Conditioning Engineering Construction" GB5024 3. The air leakage allowed by the air supply pipeline should be determined according to the working pressure, and the smoke exhaust pipeline should be determined according to the rules of medium pressure system.

　　4.管道與風機的銜接，宜選用法蘭銜接，或選用不焚燒資料的柔性銜接。

　　4. Flange connection or flexible connection of non-incineration data should be selected for the connection between pipeline and fan.

　　5.管道穿越隔墻時，管道與隔墻之間的空隙，應選用水泥砂漿等非焚燒資料緊密填塞。

　　5. When the pipeline passes through the partition wall, the gap between the pipeline and the partition wall should be filled tightly with non-incineration data such as cement mortar.

　　6.排煙管道的隔熱層應選用厚度不小于40mm的不燃絕熱資料進行隔熱(如礦棉、巖棉、硅酸鋁等)。
