1. Dab tsi yog swb-ntawm flanges?
Lub qhov taub loj dua cov yeeb nkab loj dua cov yeeb nkab lub taub (OD), tso cai yooj yim .
Ib lub hub nyob rau sab hauv ntsej muag uas ua raws li kev qhia thiab muab vuam npoo .
Ntau yam nyob rau hauv cov nruab nrab-rau-nruab nrab nruab nrab (e .}}}}}}}
{{0 {}} Yuav ua li cas kom haum ib qho khau khiab-rau Flange?
Npaj cov yeeb nkab:
Txiav cov yeeb nkab kom ntev thiab debur kawg kom tshem tawm cov ntse .
Nco ntsoov tias cov yeeb nkab sab nrauv yog huv thiab tsis muaj xeb lossis khib nyiab .
Swb cov flange:
Txoj hauj lwm flange tshaj cov yeeb nkab kawg, cia lub hub kom txuas me ntsis dhau ntawm cov yeeb nkab (feem ntau 1/8 rau kev tsim kho vuam) {}
Dlhos cov flange ntsia qhov nrog cov mating flange (yog tias ua ntej sib sau) .
Tus kheej weld:
Ruaj ntseg lub flange nrog ib ntus tom ob lossis peb lub ntsiab lus nyob ib ncig ntawm lub hub kom tiv thaiv kev txav .
Txheeb xyuas cov txheej txheem siv cov dab neeg sab ntsuj plig lossis cov ntawv ncaj qha kom ntseeg tau tias lub ntsej muag flange yog txiav rau cov yeeb nkab .
Tas Nrho Vuam:
Ua ib qho kev txuas tas mus li weld ncig lub hub-yeeb sib tshuam, raws li cov chaw tsim khoom specifications (e. kub, tus naj npawb ntawm passes).
Rau cov ntawv thov siab dua, ob npaug fillet weld (sab hauv thiab sab nraud) yuav tsum tau .
Soj ntsuam thiab ua tiav:
Tshawb xyuas Welds rau tej yam tsis xws luag (e {.}}}}}
Siv cov txheej corrosion rau lub welded thaj chaw yog tias xav tau .
3. Dab tsi yog qhov zoo ntawm cov khau khiab-ntawm flanges?
Nqi-Zoo: Pheej yig dua los tsim cov caj dab dua li weld caj dab flanges vim yooj yim tsim thiab cov khoom siv tsawg {}}
Installation Yooj Yim Installation: Nrawm los kho thiab Weld, txo lub sijhawm ua haujlwm thiab cov nqi, tshwj xeeb rau cov kav dej loj.
Zam txim siab: Cov ris tsho loj heev tso cai rau cov menyuam tsis ncaj ncees thaum teeb tsa, ua rau lawv haum rau kev kho kom haum .
Lub teeb yuag: Sib dua tshaj weld caj dab flanges, zoo tagnrho rau cov ntawv thov uas qhov hnyav yog qhov kev txhawj xeeb (e {}} pa} {{2}
Ntau yam: Haum rau dej, roj av, thiab tsis muaj cov kua dej uas muaj kuab phom nrog kev kub siab / ntsuas kub.
4.Dab tsi yog qhov tsis zoo ntawm kev plam ntawm cov flanges?
Txo lub zog: Fillet Welds tsis muaj zog dua li pob tw welds (siv nyob rau hauv weld caj dab los yog siab rau ib puag ncig muaj siab los yog siab.
Muaj peev xwm tswg cov ntsiab lus: Weld tsis xws luag los yog tsis tsim nyog installation tuaj yeem ua rau muaj kev xau, tshwj xeeb tshaj yog hauv kev xeb lossis kev phom sij media {}}
Flunence Cua: Lub hub sab hauv yuav me ntsis kev cuam tshuam cov kua dej ntws piv rau seamless weld caj dab flanges {}}
Tsawg tus kub / siab: Not rated for extreme conditions (e.g., temperatures >400°F or pressures >Chav kawm 400) .
Txo kev qaug zog tsis kam: Tsis tshua muaj zog nyob rau hauv cov kab ke nrog kev caij sov thermal lossis kev sib tw, nce txoj kev pheej hmoo weld tsis ua hauj lwm {}}
{{0 {}} Thaum tsis txhob siv ib qho khau khiab-rau flange?
Kev Ntsuas Siab: Applications exceeding Class 400 or requiring pressures >400 psi (e {{{{{1} g}!
Kev kub-ib puag ncig: Kub tshaj 400℃f (204 degree), qhov twg thermal expansion tuaj yeem ntxhov siab Fillet Welds .
Kev phom sij lossis lom cov kua dej: Cov tshuab nqa cov nplaim, xeb, lossis cov tshuaj lom, qhov chaw weld zoo nkauj (siv Weld Neck Flanges rau kev ntseeg siab dua) .
Cyclic Chaw thau khoom lossis kev co: Kev lag luam zoo li nroj tsuag fais fab lossis sab nrauv platform, qhov twg tas mus li txav tau muaj zog fillet fillet fillet fills .
Daim Ntawv Thov Kev Nyab Xeeb Kev Nyab Xeeb: Cov tshuab yuav tsum tau code-ua raws li, e {{{} Cov qauv kev tiv thaiv), qhov twg yog cov qauv hluav taws xob tuaj yeem muab tso rau hauv Welded-Welded Felanges {}}
Cov kab zauv loj hauv kev ntxhov siab: For pipes >12 nti hauv txoj kab uas hla nrog kev pheej hmoo siab, kev pheej hmoo ntawm flange distorte nce, nyiam muaj zog weld caj dab tsim {}}
