The traditional design criteria for bolted flanged connections was based on the strength failure, which cannot evaluate in quantity the tightness of flange joints.
傳統的法蘭設計依據強度失效判據,不能定量估計法蘭接頭的緊密性。
All expansion joints shall have bolted flange-to-flange type connections on both sides of expansion joint for removal of complete unit. Minimum flange thickness shall be 6 mm.
所有的伸縮接頭(膨脹節)都應當采用法蘭栓接。法蘭的最小厚度為6毫米。
The elbow shall be bolted to the floor of the wet-well and be so designed as to receive the pump connecting flange without the need for any bolts, nuts or clamps.
彎頭應該用螺栓固定在濕井地面,并且設計成具有不需要任何螺栓、螺母或皮帶即可連接泵設備的連接法蘭的能力。
"Bolted flange"是機械工程和管道系統中常用的連接結構,由法蘭(flange)和螺栓(bolt)兩部分組成。法蘭指帶有均勻孔洞的環形金屬盤片,通常焊接在管道、閥門或設備端口邊緣;螺栓則穿過兩個法蘭的對應孔洞,通過螺母緊固,形成可拆卸的密封連接系統。
該結構包含三個核心組件:
在工業應用中,這種連接方式常見于石油化工管道系統、核電站主蒸汽管線、城市給排水管網等場景。其優勢在于承壓能力可達2500Psi以上,且允許定期拆卸維護,顯著優于焊接式固定連接。美國石油學會(API)在SPEC 6FD-2018标準中詳細規定了高溫高壓工況下的法蘭連接測試方法。
"bolted flange"是機械工程領域的專業術語,其含義和用法可歸納如下:
"bolted flange"指通過螺栓連接的凸緣結構,主要用于管道、閥門或機械部件的密封性連接。其中:
螺栓需按對角線順序均勻緊固,避免因受力不均導緻洩漏。重要系統需進行強度和密封性分析(如ASME标準)。
