1, 薄鋼板風管
1, thin steel plate wind pipe
（1）風管按不同規(guī)格以展開面積計算，管上檢查孔、測定孔、送風口、吸風口等所占面積不扣除。
(1) the wind pipe is calculated according to different specifications, and the area of the inspection hole, measuring hole, air outlet, suction outlet and so on is not deducted.
（2）計算風管長度時一律以圖注中心線長度為準，包括彎頭、三通、變徑管、天圓地方等管件的長度，但不得包括通風部件（如風閥、風口等）所在位置的長度。風管直徑和周長按圖注尺寸展開。但咬口風管的接口及翻邊量不得計算在展開面積內(nèi)。
(2) the calculation of wind pipe length will note to center line length, including three links, elbow, tube, square fitting length, but not including ventilation components (such as air valve, etc.) the location of the length. The diameter and circumference of the wind pipe are expanded according to the size of the drawing. But bite interface and flanging pipe was not calculated in the tone expansion area.
（3）風管導流葉片按葉片的面積計算。

(3) the guide vane of the wind pipe is calculated according to the area of the blade.
（4）風管附件（除軟性接頭按計算外），檢查孔、測定孔等按不同類型、規(guī)格分別以個為單位計算。
(4) the accessories of the wind pipe (except for the soft joint according to the square meter), the inspection holes and the measurement holes are calculated separately by different types and specifications.
2,不銹鋼風管及鋁板風管
2, stainless steel wind pipe and aluminium plate wind pipe
風管的計算規(guī)則同薄鋼板風管，部件按設計成品重量計算。
The calculation rules of the wind pipe are the same as the thin steel plate wind pipe, and the parts are calculated according to the weight of the finished product.
3. 塑料風管及部件
3. plastic wind pipe and parts
（1）風管按圖注不同規(guī)格以展開面積計算，檢查孔、測定孔、送風口、吸風口等所占面積不扣除。
(1) the wind pipe is calculated according to the different specifications of the drawing, and the area of the check hole, the measuring hole, the air outlet and the suction outlet are not deducted.
（2）計算風管長度時，一律以圖注中心線長度為準，包括彎頭、三通、變徑管、天圓地方等管件的長度，但不得包括通風部件（如風閥、風口等）所在位置的長度，風管直徑和周長以圖注尺寸展開。
(2) the calculation of wind pipe length, all to note center line length, including three links, elbow, tube, square fitting length, but not including ventilation components (such as air valve, etc.) the location of the length, size of wind tube diameter and circumference to note expansion.
（3）標準部件和非標準部件均按成品的重量計算。
(3) both standard and non - standard components are calculated according to the weight of the finished product.
