4、還有一點(diǎn)，帶頸對(duì)焊法蘭與接管連接的焊縫屬B類縫，帶頸平焊法蘭與接管連接的焊縫屬C類縫，焊后無(wú)損檢測(cè)不一樣。 5、帶頸平焊法蘭與帶頸對(duì)焊法蘭不能隨便替換，就制造角度而言，沈陽(yáng)冶金行業(yè)帶頸平焊法蘭，帶頸平焊法蘭（SO是SLIP ON縮寫）內(nèi)徑大，意味著重量小，成本就低，另外公稱直徑大于250mm的帶頸對(duì)焊法蘭（WN是WELD NECK的縮寫）要檢測(cè)，SO的法蘭不需要檢測(cè)，所以成本就低了。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"
