Nco ntsoov {0-} ntawm cov ntawv thov flange thiab cov kev txiav txim siab txhim kho

Raws li ib qho cov yeeb nkab sib txuas, zawv zawg Flange ua lub luag haujlwm tseem ceeb hauv kev lag luam piping. Nws muaj cov qauv yooj yim, cov nqi tsim qauv tsis muaj, yooj yim installation thiab yog siv dav hauv ntau qhov chaw ua haujlwm. Kab lus no yuav qhia txog daim ntawv thov, cov kev txiav txim siab tsim qauv, kev txhawb nqa cov ntsiab lus ntawm Fliing Flange thiab zam dhau kev ua tsis tau zoo ntawm kev siv.
Cov qauv theem pib thiab cov yam ntxwv ntawm zawv zawg flange
Lub zawv zawg flange yog tsim ntawm lub ntsej muag flange thiab tiaj tus - caj dab. Lawv xaus yog tsim los ua qhov chaw tiaj tiaj ntawm cov ces kaum sab xis rau vuam kav dej, feem ntau los ntawm kev kub taub hau lossis taub hau viav vias. Nws lub ntsiab tseem ceeb yog cov qauv yooj yim, vuam loj vuam, muaj kev siab hnyav thiab cov txheej txheem tsim khoom siv hluav taws xob. Txij li thaum nws lub suab sib khi tau yaug nrog qhov kawg ntawm cov yeeb nkab, nws yooj yim kom sib sau ua ke, tshem tawm thiab tswj hwm. Txawm li cas los xij, lawv lub zog tshuab zog thiab tensile lub zog yog qhov tsawg thiab tsis haum rau kev nce siab.
Daim Ntawv Thov Kev Ntsuam Xyuas
Kev xaiv ntawm zawv zawg flamer yuav txiav txim siab raws li kev thov ib puag ncig thiab cov txheej txheem tseev kom muaj. Tsuas yog nrog kev tsim nyog ua ke tau nws txoj kev ua tau zoo tau pom meej. Qaum ...-} ntawm flanges yog qhov haum rau cov twj luam nrog cov siab thiab kub kub. Nws yog ib qho uas siv tau hauv cov piping, hvac, faib khoom thiab cov kua roj ntau.
Nyob rau hauv cov nqe lus ntawm cov ntaub ntawv thiab loj, npleem -}} ntawm flanges yog ua los ntawm cov roj carbon hlau, hlau stainless thiab lwm yam khoom siv. Yog hais tias txoj kab uas hla los yog lub siab loj, taub hau - Weld Flanges lossis lwm hom Flange raug pom zoo thiab deformation kev pheej hmoo ntawm kev sib koom tes.
Ruam -}} ntawm flanges tseem tuaj yeem siv los txuas cov qauv kev cia khoom xws li ASME thiab GB kom ntseeg tau tias muaj kev nyab xeeb.
Tus Qauv Tseem Ceeb thiab Kev Xaiv Xaiv
Thaum lub sij hawm tsim theem, cov hauv qab no yuav tsum tau hais meej:
1 Yog tias lub siab ntsuas tshaj qhov no, pob tw - weld flanges lossis lwm yam flas pab cuam uas yuav tsum muaj.
2. Cov Khoom Siv Hluav Taws Xob: Cov khoom siv Flange yuav tsum sib phim nrog cov khoom siv cov yeeb nkab kom tsis txhob muaj kev pheej hmoo zoo los ntawm kev ua kom muaj zog hluav taws xob. Piv txwv li, flanges nrog kev tsis zoo corrosion tsis kam siv rau cov kav hlau hlau.
3. Txheej Txheem Hloov Kho: Xav txog qhov yooj yim ntawm vuam thiab seb puas muaj chaw txaus thiab cov xwm txheej kom tiav tiaj tus tiaj tus.
4. Xaiv cov Flange Sealing Npog: Flange feem ntau adopts Ca {}} Weld Sealing RelieS, tsis haum rau siab- siab} Kev siab siv. Ceev faj yog pom zoo.
Kev ceev faj thiab cov ntsiab lus tsim
Cov teeb meem tshwm sim hauv cov txheej txheem teeb tsa feem ntau yog vim tsis saib xyuas kev nthuav dav, uas cuam tshuam rau kev nyab xeeb thiab kev ruaj ntseg ntawm tag nrho cov raj dej piping.
1. Kev ua siab zoo vuam ua tau zoo. Flat-weld flanges is directly connected by end-to-end welding. Lub zog thiab kev sib khi ua tau zoo ntawm kev sib koom ua ke tau txiav txim siab ncaj qha los ntawm qhov zoo ntawm vuam. Ua ntej vuam muag, thaj chaw Weld yuav tsum ua tib zoo ntxuav kom tiv thaiv cov pa phem rau roj, xeb thiab impurities uas yuav cuam tshuam rau qhov zoo ntawm kev vuam.
2. Tswj vuam deformation. Txij li thaum vuam tshav kub tawm tswv yim yuav ua rau muaj kev ntxhov siab thiab cov yeeb nkab, tiv thaiv flange kev ntxhov siab thiab tiv thaiv flanging los ntawm detaching thiab warping.
3. Tswj flange txoj kev ncaj ncees thiab sib ncag. Thaum lub sijhawm theem bolting, xyuas kom meej tias cov nplaim flange yog sib xws thiab coaxial los tiv thaiv qhov chaw ntawm cov chaw sib tsoo tshwm sim los ntawm kev tshem tawm.
4. Thov cov ntsia liaj qhov rooj kub heev. Symmetrically nruj siv cov cuab yeej tsim nyog torque thiab cov kev qhia tshwj xeeb kom tsis txhob muaj kev cuam tshuam hauv zos lossis txo qis.
5. Kom zoo gasket installation. Xaiv cov khoom siv gasket thiab txiav txim siab cov lus qhia tshwj xeeb thiab cov khoom siv raws li nruab nrab, siab thiab ntsuas kub. Gaskets yuav tsum yog tiaj tus, wrinkle - dawb thiab tsis puas.
6.post -} vuam soj ntsuam. Tsis - Kev sim tshuaj, xws li kev ntsuas hluav taws xob (NDT, kev sib tw yog qhov sib txawv, kom paub meej, kom ntseeg tau tias qhov zoo ntawm vuam.
7.Mon-flueform flange kev ntxhov siab thaum lub sijhawm ua haujlwm los tiv thaiv kev sib koom ua haujlwm vim kev quab yuam sab nraud lossis thermal nthuav dav.
Cov ntsiab lus uas yuav raug saib xyuas
1.Long - lub sij hawm}} Qhov chaw nres nkoj lossis kev tiv thaiv kab mob flange yog cuam tshuam nrog flange lub neej, thiab feem ntau tsis quav ntsej los ntawm cov neeg siv.
2.Dynamic thauj cov kev sib txuas ntawm Flange sib txuas: kev co thiab hluav taws xob nthuav yuav tshwm sim thaum lub sijhawm ua haujlwm. Yog tias tus qauv tsim thiab teeb tsa ntawm cov flanges tsis coj mus rau hauv tus account dynamic loads, qaug zog tsis muaj zog yuav tshwm sim.
3.Qhov cim cim thiab muaj pes tsawg leeg: flange yuav tsum tau txheeb xyuas thiab txheeb xyuas los ntawm cov khoom siv los pab txhawb kev kho yav tom ntej thiab ua kom muaj kev ncaj ncees ntawm cov piping system.
4.Protection thaum lub sijhawm cia thiab thauj: flange zawv zawg, tshwj xeeb tshaj yog cov khoom sib luag yooj yim rau kos, cuam tshuam rau cov nyhuv seading thaum installation. Cov chaw ua haujlwm yuav tsum tau tiv thaiv tawm tsam kev puas tsuaj thiab paug.
5. Txaus siab Flange Spare cov khoom lag luam: Raug kev puas tsuaj los yog xeb yuav ua rau flange tsis ua haujlwm. Tsim nyog cov khoom lag luam seem seem uas txaus yuav txo ntau ntau lawm downtime.
