說(shuō)到白鐵皮通風(fēng)管道的制作要求，來(lái)講，對(duì)于設(shè)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(shí)也就是要注意一下法蘭螺栓在間距上的要求，對(duì)于通風(fēng)管道上的空調(diào)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(lái)，就白鐵皮通風(fēng)管道在進(jìn)行制作和加工的時(shí)候，講到排煙系統(tǒng)上的白鐵皮風(fēng)管間距應(yīng)該是要小于100MM。對(duì)于四角距法蘭邊的地方，對(duì)于其法蘭螺栓不可以超過(guò)50MM。對(duì)于所有吊架應(yīng)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(fēng)管道在進(jìn)行加工的時(shí)候，對(duì)于其吊桿如搭接來(lái)講，我們其實(shí)也就是要注意應(yīng)該是要注意對(duì)于它的搭接長(zhǎng)度應(yīng)該是要大于60MM才可以。再者，就白鐵皮風(fēng)管咬口縫應(yīng)該是要注意錯(cuò)開(kāi)，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(gè)方面來(lái)講，對(duì)于白鐵皮通風(fēng)管道應(yīng)該是要注意先從接口和彎頭、變徑上開(kāi)始做起，不可以隨意去改變彎頭與其變徑接頭尺寸，對(duì)于它的彎頭來(lái)講的話，就其本身也就是應(yīng)該是應(yīng)該保證內(nèi)外側(cè)表面為同心圓，不然，就其邊長(zhǎng)上也就是要注意大于500MM的時(shí)候也就是應(yīng)該是要去進(jìn)行設(shè)置導(dǎo)流葉片，一般情況之下不可以進(jìn)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.
