說到白鐵皮通風管道的制作要求，來講，對于設備上的支吊架以及其法蘭或者是加固框一定的是要注意除銹徹底，一直到除去表面氧化層為止。緊接著，就其在很大的程度上其實也就是要注意一下法蘭螺栓在間距上的要求，對于通風管道上的空調系統(tǒng)間距要注意必須是要小于或者是等于120MM。

As for the manufacturing requirements of galvanized ventilation pipes, first of all, for the supports and hangers on the equipment and their flanges or reinforcing frames, it is necessary to pay attention to the thorough rust removal until the surface oxide layer is removed. Then, to a large extent, it is necessary to pay attention to the requirements of flange bolt spacing. For the air conditioning system spacing on the ventilation duct, it must be less than or equal to 120MM.

接下來，就白鐵皮通風管道在進行制作和加工的時候，講到排煙系統(tǒng)上的白鐵皮風管間距應該是要小于100MM。對于四角距法蘭邊的地方，對于其法蘭螺栓不可以超過50MM。對于所有吊架應該是要注意除毛刺和采用鉆孔，不可以用氧氣吹孔。

Next, when making and processing the galvanized air duct, it was mentioned that the spacing of galvanized air duct on the smoke exhaust system should be less than 100MM. The flange bolts at the places with four corners away from the flange edge shall not exceed 50MM. For all hangers, attention shall be paid to deburring and drilling, instead of blowing holes with oxygen.

再者，就白鐵皮通風管道在進行加工的時候，對于其吊桿如搭接來講，我們其實也就是要注意應該是要注意對于它的搭接長度應該是要大于60MM才可以。再者，就白鐵皮風管咬口縫應該是要注意錯開，不可以有十字型拼接縫。

Moreover, when processing the galvanized air duct, we should pay attention to the overlapping length of its suspenders, such as more than 60MM. Moreover, the seaming of galvanized air duct shall be staggered, and no cross seam is allowed.

就下一個方面來講，對于白鐵皮通風管道應該是要注意先從接口和彎頭、變徑上開始做起，不可以隨意去改變彎頭與其變徑接頭尺寸，對于它的彎頭來講的話，就其本身也就是應該是應該保證內外側表面為同心圓，不然，就其邊長上也就是要注意大于500MM的時候也就是應該是要去進行設置導流葉片，一般情況之下不可以進行采用。

In terms of the next aspect, for the galvanized air duct, attention should be paid to starting from the interface, elbow and reducer. The size of the elbow and its reducer joint should not be changed at will. For its elbow, it should ensure that the inner and outer surfaces are concentric, otherwise, it should pay attention to the setting of guide vanes when the side length is greater than 500 mm, Generally, it cannot be adopted.
