Cov Qauv Txheem Cov Flanges
1:Vuam caj dab flange
Ib lub vuam caj dab flange ("wn") nta lub hub ntev tapered hub uas tuaj yeem welded nrog ib tug yeeb nkab.
Qhov chaw flange yog siv, nquag, hauv cov ntawv thov siab siab thiab muaj kev txwv tsis pub dhau los ntawm cov kav dej uas yuav tsum muaj qhov tsis muaj kev cuam tshuam nrog lub raj nplaim flange nrog lub raj raj ntawm cov yeeb nkab).
Qhov tsis muaj lub siab poob txwv tsis pub tsis zoo li kev kub ntxhov thiab kev yaig / corrosion ntawm cov hlau hauv qhov sib thooj ntawm cov pob qij txha flanged.
Lub chaw faib khoom uas tau tso cai rau kev sib cais ntawm cov yeeb nkab kev ntxhov siab ntawm cov yeeb nkab thiab kev tshuaj xyuas weld ntawm cov xov xwm hluav taws xob los kuaj pom tau yooj yim thiab kev siv vuam tsis zoo.
Qhov ntev ntawm cov flange (Nps thiab cov raj nplaim) yuav tsum phim qhov ntev ntawm cov yeeb nkab txuas.
2:Ntev vuam caj dab
Ntev Weld Neck Flanges ("Lwn") zoo ib yam li weld caj dab flanges, nrog kev zam uas yog caj dab (tapered hub (tapered hub) yog txuas ntxiv thiab ua zoo li boring txuas ntxiv.
Ntev weld caj dab caj dab yog feem ntau siv rau cov hlab, kab lossis cov ntoo. Cov hom flange no tseem muaj nyob hauv cov thoob dej hnyav (HB) thiab sib luag (e) hom.
3:Npleem ntawm flange
Ib qho khau khiab-ntawm flange tau txuas nrog cov yeeb nkab lossis cov fittings los ntawm ob Fillet Welds, ib qho sab hauv thiab ib sab nraum qab kab noj hniav ntawm cov flange.
Nplaim-ntawm Flanges tseem tau txhais "Hubbed Flanges" thiab lawv yooj yim kom paub vim lawv cov slim thiab compact duab.
4:Xov flange
Threaded flanges muaj nyob rau hauv ntau thiab tsawg txog 4 nti, txawm li cas los xij, feem ntau, cov ntawv thov me me, zoo li dej thiab cov chaw pabcuam dej.
Threaded flanges kuj yog ib qho yuav tsum tau ua rau thaj chaw tawg, xws li tua hluav taws xob thiab cov ntoo sib txuas, raws li kev tua ntawm welded sib txuas nyob rau hauv xws li ib puag ncig yuav txaus ntshai.
5:Qhov (socket) weld flange
Qhov (qhov chaw weld
Raws li ASME B31.1, kom ua kev sib txuas Flanged siv rau hauv lub qhov (cov yeeb nkab tom qab ntawm cov flange, tom qab ntawd nws yuav tsum tau nqa los ntawm 1.6 hli thiab thaum kawg welded.
Qhov no sib kis yuav tsum tau tso cai rau kev tso cai ntawm cov yeeb nkab hauv Flange ntsaws Flange tom qab kev sib tw ntawm Weld.
Qhov (socket (weld
Qhov no vim yog qhov tseeb tias cov flange hom yog kev xeb hauv thaj chaw sib txawv ntawm qhov kawg ntawm cov yeeb nkab thiab lub xub pwg ntawm lub qhov cub.
Lawv lub zog zoo li lub ntsab ntawm lub qhov (weld flanges yog zoo li swb-ntawm flanges-ntawm flanges ', tab sis lawv cov roj flowb muaj siab dua yog ib qho, hloov ob npaug, tsuas yog siv ob zaug, fillet weld.
6:Muab cov hlua khi ua ke
Muab cov ceg tawv ua ke ua rau muaj lub ntsej muag tiaj tus thiab ib txwm siv ua ke nrog tus qij kawg.
Ib ceg tawv nqaij flange rau cov yeeb nkab thiab cov rooj zaum nyob sab nraum qab ntawm lub stub kawg thiab ob tus neeg tau khaws cia ua ke los ntawm lub siab ntawm cov bolts.
Kev siv ntawm ncej puab pob qij txha sib xyaw nrog cov khoom siv sib xyaw ua ke yog cov khoom siv ntawm ceg tawv nyias nyias (uas yuav tsum phim cov yeeb nkab qib, raws li tau chwv nrog cov kua dej sib txuas).
Qhov kev npaj no, yog li ntawd, muaj ob qho zoo no:
A: txo cov nqi ntawm cov raj xa hluav taws xob tag nrho cov kab ke, raws li kev siv cov khoom siab dua yog qhov tsawg
B: Bolting kev ua haujlwm yog qhov yooj yim, raws li txoj kab sib tw ncej puab yuav tig tau los pab nrog cov bolts sincment.
7:Qhov muag tsis pom Flange
Rov qab rau txhua tus flange hom pom saum toj no, dig muag tsis muaj qhov muag tsis pom kev, thiab siv lub nkoj dig muag thiab txhaws cov dej ntws.
Qhov muag tsis pom flanges yuav tsum tiv thaiv cov neeg kho tshuab zoo tshaj vim yog lub kaw lus siab thiab cov tub rog xav tau.
Qhov muag dig muag Flanges cia kev nkag tau yooj yim rau cov raj xa dej, raws li lawv tuaj yeem yog vim li cas lub laj thawj uas yog vim li cas qhov muag pom flessels, nyob rau lub sijhawm).
Nws yog tej zaum ntxim nyiam kom soj ntsuam uas, thaum cov flanges no yog qhov yooj yim rau kev tsim khoom, lawv tau muag ntawm tus nqi hwm ntawm nruab nrab ib phaus ib phaus ntawm ib hom flange.
