對于非采購的現場鍍鋅風管加工廠制作風管，因受加工工藝及加工場地、加工方法、加工設備、操作人員的不同，其質量情況會有所不同，為檢驗其加工工藝是否滿足施工要求，在鍍鋅風管加工廠制作風管批量加工前，應對現場加工制作的風管進行嚴密性和強度試驗，也就是要對加工工藝進行驗證。</span> </p> <p> <span><span style="font-size:14px;"> 鍍鋅風管加工廠制作工藝性驗證，就是為了驗證加工工藝是否符合要求而進行的強度和嚴密性試驗;是在風管批量加工前，先加工出一部分樣品進行試驗，合格后方可大批量加工。檢驗應該是全數檢驗，檢驗合格后方可進行下一道工序，批量加工。</span><span style="font-size:14px;"></span></span> </p></div> </td> </tr> </table> </p>
