                    • 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。

                    • 法蘭的維修

                      管道長期使用后,墊片會發生泄漏。當更換墊片時,法蘭又難以張開,可采用自制簡易工具,把兩片法蘭撐開。

                    • 不銹鋼彎頭基本知識

                      我國經濟快速發展的推動下,各行各業都獲得了相當不錯的發展,不銹鋼管件市場的競爭也在不斷加劇,作為食品、藥品加工及包裝行業的下游產業。不銹鋼管件的影響也日益加劇。
