        2、管道吊架距法蘭距離不小于20mm。柔性短管長度為150~300mm.金屬軟管及非金屬軟管長度不得大于2m,并不用有死彎或塌凹。
        2. The distance between pipe hanger and flange shall not be less than 20 mm. The length of flexible short pipe is 150-300 mm. The length of metal hose and non-metal hose shall not be more than 2 m, and there is no dead bend or collapse.
        3、主通風管道吊架距支管之間的距離應不小于200mm。
        3. The distance between the main ventilation pipe hanger and the branch pipe shall not be less than 200mm.
        4、法蘭螺栓孔距低壓送風不大于200mm,中壓送風距離不大于100mm。5 ) 通風管道彎頭處、三通處、閥門處、必須加吊架、管道長度超過15m,防晃支架不得少于一個。
        4. The distance between the flange bolt hole and the low-pressure air supply shall not be greater than 200mm, and the distance between the middle pressure air supply shall not be greater than 100mm. 5) hangers must be added at the elbows, tees and valves of the ventilation pipes. The length of the pipes is more than 15m, and there shall be no less than one anti sway support.
        6、通風管道吊架距不保溫通風管道邊緣為30mm,距保溫通風管道保溫層邊緣距離為30mm。
        6. The distance between the hanger of the ventilation pipe and the edge of the uninsulated ventilation pipe is 30mm, and the distance between the hanger and the edge of the insulation layer of the insulated ventilation pipe is 30mm.
        7、通風管道保溫應平整,法蘭處必須單獨保溫,法蘭保溫材料應與管道一致。通風管道水平度為3‰,垂直度2‰,總體偏差均不大于20mm。
        7. The thermal insulation of the ventilation pipe shall be flat, and the flange must be insulated separately, and the flange thermal insulation material shall be consistent with the pipe.
