除使用鋼管為原料生產(chǎn)大小頭外，對部分規(guī)格的大小頭還可用鋼板采用沖壓成形工藝進行生產(chǎn)。拉伸所使用的沖模形狀參照大小頭內(nèi)表面尺寸設計，用沖模將下料后的鋼板沖壓拉伸成形。大小頭粘接前，應用干布將承口側(cè)和插口外側(cè)擦拭處理，當表面粘有油污時須用**擦拭干凈，有以下幾點要注意： 1、控制口徑：DIN標準（DN10-DN150）、3A/IDF標準（1/2"-6")、ISO標準（Ф12.7-Ф152.4)； 2、國際工業(yè)標準：DIN、ISO、SMS、3A、IDF等； 3、產(chǎn)品材料：不銹鋼304、316、316L； 4、質(zhì)量與用途：大小頭內(nèi)外用好拋光設備處理，達到表面精密度要求；此產(chǎn)品適用于乳品、食品、啤酒、飲料、制藥、化妝品等工業(yè)領域；</p><p style="text-indent:25px">大小頭標準國標美標英標以及各種非標產(chǎn)品。電力部標準GD0506~0507壓力容器配套的法蘭、管板相應標準：NB/T
