Okushiwo Isilinganiso Sekilasi lochungechunge lwe-B16 flange: Isilinganiso sekilasi siqanjwe ngokuya ngengcindezi evumelekile (8750PSI) ye-A105,WCB 1.1 impahla yeqembu ngaphansi kuka-454°C kanye nesilinganiso sokucindezela esisekelwe ku-60.3MP:

• P1=(10S/8750)*Pr≤Pc

I-P1 - isilinganiso sokucindezela kwe-flange ekushiseni okuhambisanayo, ibha.
S - inani elivumelekile lokucindezeleka lezinto ze-flange, i-MPa.
Pr – flange Class value.

I-Pc – Ibha yokulinganisa ukucindezela okukhulu.

Nge-flange yezinto ezibonakalayo 150# ngokucindezela okuvumelekile kwe-100MPa, iyatholakala (10*100/8750)*150=17Bar=1.7MPa.Ilingana nokucindezeleka okuvumelekile kwe-150 # flange, ukucindezela kwayo okuvunyelwe ukusebenza okungu-1.7%.

Imibandela yokunquma indawo ye-Bolt yochungechunge lwe-B16 flange:
Ngokuxhumeka kwe-flange noma i-valve yomzimba:

• AB *7000Psi≥Ag*Pc-> AB *120MPa≥Ag*Pg

U-Ab - indawo enqamulayo yebhawodi
Indawo yokuxhumana ye-Ag gasket ngaphakathi nangaphandle ububanzi (kufaka phakathi indawo ene-gasket diameter yangaphakathi).
I-Pc - Ibanga lekilasi le-flange
Umthamo wokuthwala webhawodi akufanele ube ngaphansi kokucatshangwa ukuthi ingcindezi yangaphakathi ingaphakathi kobubanzi obungaphandle bokuvalwa kwe-gasket lapho ingcindezi evunyelwe ilingana no-120MPa.Ngokuxhunywa kwe-flange, i-a193b7 bolt enamandla okwenza isivuno angu-105ksi (724mpa) ngokuvamile isetshenziswa, futhi isici sokuphepha somklamo webhawodi ngu-ns ≥ 6. Ngakho-ke, indawo yebhawodi ye-ASME B16.5 flange inkulu kunaleyo ye-ASME VIII I non -i-flange ejwayelekile.Ngenxa yenani elikhulu lemali enqwabelene yebhawudi, amandla e-flange ngokuvamile awafaneleki lapho ebalwa ngokuya ngefomula.Kodwa empeleni, i-flange iphephile, yingakho incazelo ibeka ukuthi i-flange ekhethiwe ngokwezinga le-flange le-B16.5 ayikwazi ukubalwa ngokuvumelana nefomula.

Incazelo ye-Sch: Sch: Isifinyezo seshejuli umpers yosayizi wamapayipi.Kusho ukuthi isilinganiso sengcindezi yokuklama isistimu yamapayipi kuya ekucindezelekeni okubonakalayo okuvumelekile ezingeni lokushisa lokuklama liphindaphindwa ngo-100 0 kanye nenani ngemva kokufinyezwa.Isibonelo, uma ingcindezi yomklamo ingu-1MPa futhi ingcindezi evumelekile yepayipi ingu-100Mpa, ipayipi eline-1/100 100 0=10 kanye> ne-Sch.10 kufanele lisetshenziswe.Kumapayipi ajwayelekile, ukucindezelwa okuvumelekile kwezinto ezijwayelekile kucishe kube ngu-100Mpa, i-Sch.80 ingathwala u-8MPa, iSch.160 ingathwala u-16MPa, njalo njalo, kukhona inkomba evamile yokukhetha i-Sch efanelekile.
