four to flush pipe end flange in a tubular surface， can be a bending machine for bending and flanging in the extension line should be equal. This is the installation of wind to butt straight pipe interface.

(4)除鐵皮法蘭彈簧夾(包括鐵皮法蘭插條)在安裝對(duì)接面加密封墊外，其它多在連接完后在接縫外涂抹密封膠，涂膠前縫口清理干凈。密封膠不能用膩?zhàn)?、石灰膏等代替，?yīng)用風(fēng)管專用膠封袋。

(4) in addition to iron flange spring clip (including steel flange installed in the docking surface and cutting) seal， the other in connection after the joint outer fluid sealant，pvc通風(fēng)管道廠家， glue before seam clean. Sealant instead of putty， lime paste， application of wind pipe special glue sealing bag.

(5)風(fēng)管安裝用支吊架按規(guī)范要求設(shè)置。風(fēng)管連接完后，玻璃鋼通風(fēng)管道，應(yīng)按規(guī)范等級(jí)要求進(jìn)行風(fēng)管漏風(fēng)量測(cè)試。

(2) 嚴(yán)格按風(fēng)管尺寸公差要求。如對(duì)口錯(cuò)位明顯將使插條插偏：小口陷入大口內(nèi)造成無法扣緊或接頭歪斜、扭曲。插條不能明顯偏斜，開口縫應(yīng)在中間，不管插條還是管端咬口翻邊應(yīng)準(zhǔn)確、壓緊，以后連接接頭才會(huì)整齊、貼緊。

(2) strictly according to the requirement of air pipe size tolerance. As the counterpart of dislocation obviously will make the cuttings inserted: a small mouth inside into partial cause can not be fastened or distorted，河?xùn)|通風(fēng)管道， skewed joints. The not significant deviation，白鐵通風(fēng)管道， open seams should be in the middle， or whether cutting pipe end bite flange should be accurate， pressing， after the joint will be neat， close.

(3) 翻邊四面管端要平齊在一個(gè)面上，小管可以一次用折方機(jī)機(jī)折出，翻邊在整個(gè)延長(zhǎng)線上應(yīng)等寬。這也是安裝對(duì)接時(shí)風(fēng)管接口平直所必須的。
