                    • 法蘭管件的運用及法蘭管件的維修

                      鑄造法蘭管件的連接是將兩根管子、管件或裝置分別固定在法蘭管件板上。通過將兩個法蘭管接頭板、法蘭墊和螺栓緊固在一起完成連接。有些管件和裝置過去都有自己的法蘭盤,這也是法蘭管件的連接方式。法蘭管連接是管道施工中重要的連接方式。法蘭管件在間斷了陰極維護輸配管網的樓幢閥處及需間斷電位分片(區)阻隔的埋地管閥井中運用。鍛造法蘭管件使用方便,能承受較大壓力。碳鋼法蘭連接件通常采用螺栓連接件,螺栓連接件在周圍兩

                    • 法蘭的連接

                      1、法蘭連接應保持同一軸線,其螺栓孔中心偏差一般不超過孔徑的5%,并應保證螺栓自由穿入。

                      無縫彎頭:彎頭用在彎管上的管件,在管道系統中用到的管件中,所占比例較大,約占80%。通常對不一樣的材料或者壁厚的彎頭采取不同的工藝。
