Butt-welding flange yog ib qho ntawm cov flanges, uas yog hais txog lub flange nrog lub caj dab thiab hloov yeeb nkab thiab txuas nrog cov yeeb nkab los ntawm lub taub qab vuam.Vim qhov ntev ntawm caj dab tuaj yeem muab faib uacaj dab taub qab vuam flangethiabcaj dab tiaj vuam flange.
Butt-welding flanges tau siv dav vim tias lawv tsis yooj yim rau deform, zoo kaw, dav siv, muaj cov kev cai nruj thiab elasticity thiab tsim nyog pob tw vuam thinning hloov.
Nrog rau txoj kev loj hlob ntawm kev tsim cov kav dej ntev ntev, pob tw-welded flange tau dhau los ua ib feem tseem ceeb ntawm kev ntsuas cov kav dej.Ua ntej thiab tom qab qhov kev sim siab, txhua ntu ntawm cov kav dej yuav tsum tau cheb los ntawm lub pob, nrog rau qhov zaus ntawm 4-5 zaug.Tshwj xeeb tshaj yog tom qab kev sim siab, nws nyuaj rau kev ntxuav cov dej hauv cov kav dej, thiab lub sijhawm ntxuav yuav nce ntxiv.
Flat vuam flange yog lwm homflange.Nws yog dav siv thiab nce qib hauv kev lag luam tshuab, thiab tau txais kev qhuas thiab kev pom zoo los ntawm ntau tus neeg siv.
Lub ntsiab daim ntawv thov ib puag ncig ntawm lub tiaj vuam flange yog tsim nyog, thiab qhov tshwj xeeb siv tus nqi thiab kev ua tau zoo ntawm cov vuam flange yuav tsum tau txiav txim siab raws li qhov xwm txheej tshwj xeeb.Flange manufacturing yog ib qho yooj yim thiab tsis tshua muaj nqi, tab sis cov vuam ua hauj lwm yog loj, cov electrode noj loj, thiab nws tsis tuaj yeem tiv taus kub, siab siab, rov khoov thiab kub hloov.Nws feem ntau yog siv rau cov kav dej nrog PN ≤ 2.5MPa, qhov kub thiab txias, thiab ua haujlwm kub t ≤ 0 ℃.
Lwm qhov yog txhawm rau vuam txheej weld nruab nrab ntawm flange thiab cov yeeb nkab, thiab tseem yuav txuas cov yeeb nkab ntxig rau hauv flange.Cov yeeb nkab thiab lub ntsej muag flange yuav tsum tau welded raws li qhov yuav tsum tau ua los ua ke.Nco ntsoov tias lub ntsej muag flange tsis tuaj yeem raug puas thaum lub sij hawm vuam, txwv tsis pub lub sealing tsis zoo.Txoj kev vuam yog phau ntawv arc vuam, thiab cov vuam xav tau los ntawm cov txheej txheem vuam siv tau.
Qhov zoo
Lub pob tw-welding flange muaj cov qauv tsim nyog, lub zog siab thiab rigidity, tuaj yeem tiv taus qhov kub thiab txias, rov kho dua thiab kub hloov pauv, kev ua haujlwm zoo sealing, thiab tsis yooj yim rau deform.Nws yog dav siv rau cov kav dej uas muaj kev kub ntxhov loj lossis kub hloov pauv lossis kub siab, siab siab thiab qis kub pipelines.Hauv cov tsev neeg, cov yeeb nkab txoj kab uas hla yog me me, thiab nws tsis tshua muaj siab, thiab kev sib txuas ntawm lub taub qab vuam flange tsis pom.Hauv chav boiler lossis qhov chaw tsim khoom, muaj cov kav dej thiab cov khoom siv txuas nrog lub taub qab vuam flanges txhua qhov chaw.
Dab tsi yog txoj kev ua ntawm taub qab vuam flange?
1. Forging cov dawb paug rau hauv square billet, ces txias bending rau hauv arc seem, annealing tom qab kev kho cua sov, thiab ces assembling mus rau hauv ib tug tag nrho lub voj voog nyob rau hauv ntsug tshuab dhos rau txheej txheem rau cov tsim thiab loj;
2. Thawj kauj ruam yog thauj mus rau qhov chaw tsim kho, thiab tom qab ntawd sib sau ua ke thiab txuas ob peb ntu arc rau hauv cov pob tw vuam flanges tiav;
3. Butt-welding flanges muaj cov qauv kev tsim khoom sib txawv hauv kev siv thiab kev tsim khoom, thiab tuaj yeem tsim thiab siv raws li cov qauv sib xws, kom paub txog kev siv tus nqi thiab kev ua haujlwm ntawm cov flanges tshwj xeeb hauv kev xyaum.
