Nyob rau hauv pipeline engineering, flange codes muaj ntau tshaj li cov ntawv luv luv; lawv ncaj qha txiav txim siab qhov ntsuas qhov system, kev teeb tsa tsis yooj yim, thiab tus nqi tag nrho. Yuav kom ua tiav qhov kev xaiv meej, ib qho yuav tsum ua ntej deconstruct "engineering logic" embedded nyob rau hauv cov core codes.
1. Qeb "Welded": Sib npaug zog thiab txheej txheem
WN (Weld Neck): "Tus Neeg Nyuaj Siab" ntawm Piping Ntiaj Teb
Yam ntxwv: Features ib tug txawv, ntev tapered caj dab tsim.
Tswv yim tswv yim: Qhov no sawv cev rau lub siab tshaj plaws specification ntawm flanges. Los ntawm kev ua pob tw-welded rau cov yeeb nkab los ua ib qho chaw seamless, nws ua tau zoo ntawm kev nqus siab hloov pauv thiab thermal stresses. Yog tias koj qhov project cuam tshuam nrog kev kub siab, huab cua kub, lossis cov xov xwm hluav taws xob / tawg, WN flange yog qhov kev xaiv kawg.
SO (Slip-On): Tus Nqi-Kev xaiv zoo
Yam ntxwv: Nta lub caj dab luv dua WN flange, tseem muaj zog ntau dua li PL flange.
Tswv yim tswv yim: Qhov no ua hauj lwm raws li ib tug upgraded version ntawm PL flange, muab ntau ruaj khov siab - bearing kev ua tau zoo. Yog tias koj pom tus qauv tiaj tus- phaj flange (PL) kom tsis muaj zog, tab sis lub pob tw -weld flange (WN) yuav tshaj koj cov peev nyiaj, SO flange feem ntau muab qhov zoo tshaj qhov sib npaug ntawm tus nqi thiab kev nyab xeeb.
PL (Plate Flange): Qhov Yooj Yim, Txhua Yam -Lub Hom Phiaj "Ua Haujlwm"
Yam ntxwv: Ib qho yooj yim tiaj tus disk tsis muaj caj dab.
Tswv yim tswv yim: Qhov no yog hom siv dav tshaj plaws hauv engineering tej yaam num. Thaum pheej yig thiab siv tau yooj yim, nws raug pom zoo tsuas yog rau cov cheeb tsam uas muaj qhov kub thiab txias, tsis tshua muaj siab, thiab cov xov xwm ruaj khov (xws li compressed cua lossis cov qauv dej).
SW (Socket Weld): Tus Cawm Seej rau me me -Ntev Piping
Cov yam ntxwv: nta ib qho bore nrog ib tug txawv "lub xub pwg nyom" los yog kauj ruam.
Tswv yim tswv yim: Tsim tshwj xeeb los daws cov teeb meem cuam tshuam nrog lub pob tw- vuam me me- tho qhov kav dej (hauv qab 2 ntiv tes lossis DN50). Cov yeeb nkab tsuas yog muab tso rau hauv lub qhov (socket) thiab welded nyob rau hauv qhov chaw, tso cai rau qhov chaw nrawm thiab ua haujlwm siab.
2. Pawg "Tsis yog-Welded & Special Function" Qeb
Th (Threaded Flange): Cov cuab yeej zoo tshaj plaws rau "Tsis muaj- Kub- Ua Haujlwm" Kev teeb tsa
Qhov zoo: Yuav tsum tsis muaj vuam, ua rau nws tsim nyog rau cov xwm txheej uas qhib hluav taws raug txwv nruj lossis qhov chaw vuam tsis zoo (xws li, ntawm cov kav dej galvanized).
Contraindications: Txij li thaum nws sealing kev ncaj ncees cia siab rau tag nrho cov threaded kev twb kev txuas, nws yuav tsum * tsis txhob * siv nyob rau hauv pipelines khiav hauj lwm saum toj no 260℃los yog raug mob heev vibration, xws li tej yam kev mob ua rau to heev tej zaum.
BL (qhov muag tsis pom Flange): "Terminus" ntawm cov kav dej
Muaj nuj nqi: Kuj feem ntau hu ua "qhov muag tsis pom flange," nws yog siv los kaw qhov kawg ntawm cov yeeb nkab lossis los ua qhov kaw ib ntus -tawm qhov taw tes.
3. Tshaj li Txoj Cai: Peb Cov Ntsiab Lus Ntxiv uas yuav tsum xav txog
Thaum koj tau txheeb xyuas cov cai tsim nyog, koj qhov kev xaiv tseem yuav tsum dhau los ntawm qhov ntxiv "kev tshuaj ntsuam" txheej txheem:
Raws li Kev Sib Txuas Logic: Xav txog seb puas yuav tsum tau muaj kev sib txuas tsis sib xws, lossis yog tias qhov xoob-ntiv nplhaib (lap joint) kev sib txuas yog qhov zoo dua rau kev yooj yim ntawm disassembly thiab ntxuav.
Raws li Daim Ntawv Thov: Qhia meej seb lub flange yog npaj rau kev sib tw nrog lub nkoj siab los yog siv rau hauv cov kav dej xa dej txheem.
Raws li Sealing Face Compatibility: Tsis txhob saib xyuas lub ntsej muag lub ntsej muag uas ua raws li lub ntsiab flange code (piv txwv li, RF rau Raised Face, FM rau txiv neej-thiab- Poj niam ntsej muag, thiab lwm yam); cov kev qhia tshwj xeeb no txiav txim siab xaiv cov gasket tsim nyog thiab cov chav kawm sealing yuav tsum tau ua.
Tswv yim Engineering: Thaum xaiv cov khoom, tsis muaj qhov "zoo" lossis "tsis zoo" - tsuas yog "zoo tshaj plaws." Kev qhia txog qib siab - tus qauv txheej txheem rau qhov tsawg- daim ntawv thov lub luag haujlwm muaj kev nyab xeeb tab sis nkim nyiaj txiag, thaum siv cov khoom siv qis - tus qauv rau kev ua haujlwm siab - daim ntawv thov ua rau muaj kev nyab xeeb tseem ceeb. Lub hom phiaj ntawm kev nkag siab cov lej no yog txhawm rau txheeb xyuas qhov tseeb qhov sib npaug ntawm kev nyab xeeb thiab tus nqi- ua haujlwm tau zoo.
