為什么(me)對(dui)(dui)風管加(jia)工工藝進(jin)行驗(yan)證(zheng)(zheng)?工程選(xuan)用的(de)成品風管應提供產品合(he)(he)格(ge)證(zheng)(zheng)或現場復驗(yan)強度(du)和嚴(yan)密性(xing);產品合(he)(he)格(ge)證(zheng)(zheng)，包(bao)括合(he)(he)格(ge)證(zheng)(zheng)和強度(du)、嚴(yan)密性(xing)試(shi)驗(yan)報告;如(ru)果對(dui)(dui)合(he)(he)格(ge)證(zheng)(zheng)有任何異議(yi)，也(ye)可在現場測試(shi)進(jin)風管的(de)強度(du)和密封性(xing)。

非外(wai)購現(xian)(xian)場(chang)(chang)加(jia)工(gong)(gong)(gong)(gong)(包括(kuo)現(xian)(xian)場(chang)(chang)制(zhi)造(zao)、委托加(jia)工(gong)(gong)(gong)(gong)和其他(ta)現(xian)(xian)場(chang)(chang)加(jia)工(gong)(gong)(gong)(gong))風(feng)管的質量會因加(jia)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)藝(yi)、加(jia)工(gong)(gong)(gong)(gong)地點、加(jia)工(gong)(gong)(gong)(gong)方法、加(jia)工(gong)(gong)(gong)(gong)設(she)備和操作人員(yuan)的不同而有所不同。為了檢查加(jia)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)藝(yi)是否(fou)符合施工(gong)(gong)(gong)(gong)要求，風(feng)管的加(jia)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)藝(yi)在風(feng)管批(pi)量加(jia)工(gong)(gong)(gong)(gong)前應進行驗證，驗證合格后方可批(pi)量加(jia)工(gong)(gong)(gong)(gong)。

現場加(jia)工風管(guan)的(de)工藝驗證是風管(guan)批(pi)量加(jia)工前的(de)抽(chou)樣(yang)檢驗，而不(bu)是全部加(jia)工后的(de)抽(chou)樣(yang)檢驗。

加(jia)工工藝驗(yan)證(zheng)是對加(jia)工后的風管外(wai)形尺寸、連接方式(shi)(shi)、補強形式(shi)(shi)、密封(feng)面進行(xing)檢查;同時，應(ying)進行(xing)強度(du)和密封(feng)性試驗(yan)。

工藝驗證的強度(du)和(he)嚴(yan)密性試(shi)(shi)驗是(shi)在不同板厚(hou)和(he)風管壓(ya)力等級下的試(shi)(shi)驗，而(er)不是(shi)在不同風管壓(ya)力下的風管試(shi)(shi)驗。

對風管加(jia)工工藝進行(xing)驗(yan)證是為了(le)保證風管的密封性和(he)強度，減少后期使用(yong)中所(suo)出現的各類問(wen)題。希望本文章能夠對您有所(suo)幫助!
