Khoom: Hubbed RF plam ntawm vuam steel yeeb nkab flanges
1, Khoom Taw qhia ntawm Hubbed RF plam ntawm vuam steel yeeb nkab flanges
Lus Txhais: Lub tiaj vuam flange nrog lub caj dab luv. Lub raj xa dej tau muab tso rau hauv txoj kab uas hla ntawm lub flange thiab tsau rau hauv cov raj xa dej los ntawm ob -sab fillet welds (nyob rau sab nraud ntawm flange caj dab thiab sab nraub qaum ntawm flange) kom ua tiav qhov kev sib txuas.
Khoom nta:
Lub caj dab luv luv: piv rau phaj vuam (PL), nws muaj zog rigidity thiab siab bearing peev xwm, txo deformation.
Vuam txoj kev: fillet welding (tsis groove vuam), kev tsim kho yooj yim thiab tus nqi qis.
Sealing nto: feem ntau siv RF (protruding nto), FF (flat deg), haum rau gasket sealing.
Qhov zoo thiab qhov tsis zoo ntawm Hubbed RF plam ntawm vuam steel yeeb nkab flanges
✅ Qhov Zoo: Kev teeb tsa yooj yim, tus nqi qis, kev nruj dua li PL flanges, muaj zog siv tau rau nruab nrab thiab qis.
❌ Disadvantages: Tsis haum rau qhov kub thiab txias / kub siab / hnyav kub cycling; Lub weld seam yog ib qho kev sib txuas, thiab nws lub zog qaug zog qis dua li ntawm welded (WN) flange.
Cov ntawv thov: dej thiab dej ntws, kev tiv thaiv hluav taws, HVAC, tshuaj lom neeg nruab nrab thiab qis qis, roj thiab roj tsheb thauj mus los, engineering engineering, thiab lwm yam.
