      為何C4鋼法蘭會出現開裂的原因?C4鋼閥門批發,C4鋼生產廠家來為您詳細講解:

  理化分析:首先,對開裂法蘭進行了化學成分分析,分析結果表明,該C4鋼法蘭及焊接材料的化學成分均符合相關標準要求。對該法蘭頸部外表面及密封面分別進行布氏硬度,其布氏硬度值符合JB4728-2000要求。在材料化學成分合格、管道安裝符合技術要求、硬度檢測合格、耐壓試驗操作規范的前提下,管道法蘭在耐壓試驗過程中開裂,說明產生的缺陷與法蘭的內部組織結構或其他未知因素有關。

  裂紋性質分析2.1 表面裂紋形貌將該泄漏法蘭從管道上切割下來,對其進行宏觀檢查,發現法蘭內表面存在裂紋,長為3mm,寬為0.5mm,裂紋及其附近已經產生銹漬;法蘭螺栓孔內表面也發現較多裂紋;法蘭密封面及其他位置發現多處非金屬夾雜物,個別非金屬夾雜物因脫落在法蘭密封面表面形成小凹坑,凹坑大為 2.0mm,小為 0.8mm,凹坑的邊緣有肉眼可見的微小裂紋。
  同批次的另外奧氏體C4鋼法蘭開展現場宏觀檢查,看見多件法蘭存在不同程度的缺陷,有的法蘭外表面存在肉眼可見的明顯裂紋。宏觀檢查結果進一步表明,對焊法蘭,法蘭泄漏與法蘭本身因素有關系。剖面裂紋形貌為進一步探求法蘭泄漏的原因,隨機選擇一件同廠家、同批次。

  且密封面上因非金屬夾雜物脫落而形成小凹坑的平焊法蘭,對其進行解剖,將其分成大小不均的三份,仔細觀察其剖面發現,法蘭的6個剖面中有4個剖面有肉眼可見的裂紋,裂紋幾乎貫穿整個剖面。選擇其中一個剖面,經粗磨、細磨、腐蝕后觀察,310s對焊C4鋼法蘭,裂紋更加明顯,幾乎貫穿了整個剖面。
