1, 薄钢板风管
1, thin steel plate wind pipe
(1)风管按不同规格以展开面积计算,管上检查孔、测定孔、送风口、吸风口等所占面积不扣除。
(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)计算风管长度时一律以图注中心线长度为准,包括弯头、三通、变径管、天圆地方等管件的长度,但不得包括通风部件(如风阀、风口等)所在位置的长度。风管直径和周长按图注尺寸展开。但咬口风管的接口及翻边量不得计算在展开面积内。
(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)风管导流叶片按叶片的面积计算。

(4)风管附件(除软性接头按平方米计算外),检查孔、测定孔等按不同类型、规格分别以个为单位计算。
(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,不锈钢风管及铝板风管
2, stainless steel wind pipe and aluminium plate wind pipe
风管的计算规则同薄钢板风管,部件按设计成品重量计算。
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. 塑料风管及部件
3. plastic wind pipe and parts
(1)风管按图注不同规格以展开面积计算,检查孔、测定孔、送风口、吸风口等所占面积不扣除。
(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)计算风管长度时,一律以图注中心线长度为准,包括弯头、三通、变径管、天圆地方等管件的长度,但不得包括通风部件(如风阀、风口等)所在位置的长度,风管直径和周长以图注尺寸展开。
(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)标准部件和非标准部件均按成品的重量计算。
(3) both standard and non - standard components are calculated according to the weight of the finished product.
