產(chǎn)品介紹

法蘭式波紋補償器由多層薄壁不銹鋼（如304、316L）或合金鋼制成的波形元件，通過彈性形變吸收管道軸向、橫向及角向位移。?采用帶頸對焊法蘭或平焊法蘭，通過焊接與波紋管兩端固定，便于螺栓連接管道系統(tǒng)。部分設計支持單端活套法蘭，以應對法蘭孔錯位問題。??導流筒引導介質(zhì)流動，減少波紋管沖刷；通過拉桿或限位螺栓控制補償量，防止過載損壞；是一種結(jié)合法蘭連接與波紋管結(jié)構(gòu)的管道位移補償裝置，廣泛應用于工業(yè)管道系統(tǒng)中。
工作原理是通過波紋管的伸縮、彎曲或偏轉(zhuǎn)吸收因溫度變化、機械振動引起的管道位移，降低應力集中風險。內(nèi)壓推力通過法蘭傳遞至管道支架，需合理設計支撐結(jié)構(gòu)以避免失穩(wěn)；法蘭間采用耐腐蝕墊片（如橡膠、金屬纏繞墊）密封，配合對角線交替擰緊螺栓確保均勻受力。?法蘭連接簡化了焊接工藝要求，適用于需要頻繁拆卸或檢修的管道系統(tǒng)，降低了安裝和維護成本。
? 適用供熱管網(wǎng)、燃氣管道等需補償熱位移的場合；化工、航天、船舶等高壓、腐蝕性介質(zhì)環(huán)境?
?安裝規(guī)范?
確保管道軸向?qū)R，避免扭曲或拉伸波紋管。
使用預變形技術(shù)（如預壓縮）提升補償效率。
安裝后需進行泄漏測試及熱負荷試驗。
維護要求?
定期檢查波紋管表面損傷及法蘭密封性。
及時清理導流筒內(nèi)雜質(zhì)，防止介質(zhì)腐蝕。
法蘭式波紋補償器通過靈活的波紋管設計與法蘭連接的可靠性，有效解決了管道熱膨脹、機械振動等問題，尤其適用于高壓、腐蝕性介質(zhì)的復雜工況。正確選型與規(guī)范安裝是其長期穩(wěn)定運行的關(guān)鍵。
