style="text-align:center;"> <img src="/images/gongyi.jpg" /> </p> <p> 1.板探：鋼板進入生產線后，首先進行全板超聲波檢驗。<br /> 2.銑邊：通過銑邊機對鋼板兩邊緣進行雙面銑削，使之達到要求的板寬、板邊平行度和坡口形狀。<br /> 3.預彎邊：利用預彎機進行板邊預彎，使板邊具有符合要求的曲率。<br /> 4.成型：在JCO成型機上首先將預彎后的鋼板的一半經過多次步進沖壓，壓成"J"形，再將鋼板的另一半同樣彎曲，壓成"C"形，最后形成開口的"O"形。<br /> 5.預焊：使成型后的鋼管合縫并采用氣體保護焊（MAG）進行連續焊接。<br /> 6.內焊：采用縱列多絲埋弧焊（最多可為三絲）在鋼管內側進行焊接。<br /> 7.外焊：采用縱列多絲埋弧焊（最多可為四絲）在鋼管外側進行焊接。<br /> 8.超聲波檢驗Ⅰ：對內外焊縫及焊縫兩側母材進行100%的檢查。<br /> 9.X射線檢查Ⅰ：對內外焊縫進行100%的X射線工業電視檢查，采用圖象處理系統以保證探傷的靈敏度。<br /> 10. 倒棱：將檢驗合格后的鋼管進行管端加工，達到要求的管端坡口尺寸。<br /> 11.包裝并入庫：合格后的鋼管根據用戶要求進行黑漆防腐，戴管端保護器，噴標并送入庫房存儲。 </p> </td> </tr>
