Butt-welding flangeyog cov yeeb nkab txoj kab uas hla thiab phab ntsa thickness ntawm lub interface kawg yog tib yam li cov yeeb nkab yuav tsum tau welded, thiab ob lub kav dej yog welded ib yam.Butt-welding flangekev twb kev txuas yog ib qho yooj yim mus use, muaj peev xwm withstand kuj loj siab. Rautaub qab-welded flanges, cov ntaub ntawv tsis zoo ib yam raws li qhov sib txawv ntawm qhov siab. Los ntawm cov ntaub qhwv asbestos uas tsis tshua muaj siab, muaj cov ntaub ntawv siab asbestos rau cov ntaub qhwv hlau. Kev loj hlob ntawm pob tw weldingflangenyob rau hauv qhov tseeb ntau lawm thiab siv nyob rau hauv ntau txoj kev thiab cov txheej txheem ntawm ntau lawm thiab cov ntau lawm, raws li lub technologies txoj kev thiab lub hauv paus ntsiab lus, rau ntau yam muaj peev xwm muaj ib tug tseem ceeb tus nqi thiab lub luag hauj lwm ntawm tej yam khoom yog ntxiv nyob rau hauv qhov tseeb ntau lawm, yog li nce tus yam ntxwv thiab tus nqi. ntawm carbon steel flange, ua zoo siv cov yam ntxwv thiab tus nqi. Hauv kev lag luam pipeline, kev siv lub pob tw-welded flange txuas hauv Chengdu yog qhov dav heev. Nyob rau hauv lub tsev, cov yeeb nkab txoj kab uas hla yog me me, thiab tsis tshua muaj siab tsis pom pob tw vuam flange kev twb kev txuas. Yog tias koj nyob hauv chav boiler lossis chaw tsim khoom, muaj cov kav dej flanged thiab cov khoom txhua qhov chaw. Nyob rau hauv cov txheej txheem ntau lawm ntawmtaub qab-welded flanges, qee qhov kev tsis sib xws thiab cov kev xav tau raug coj los siv rau kev tsim khoom thiab daim ntawv thov kom ntseeg tau tias siv tau thiab nce qib raws li qee txoj hauv kev thiab cov qauv. Peb cov npoj yaig txais yuav qee cov txheej txheem thev naus laus zis thiab cov hauv paus ntsiab lus rau kev tsim khoom thiab vuam kom ntseeg tau tias muaj txiaj ntsig zoo ntawmtaub qab-welded flangeshauv kev siv.

Cov khoom qib thiab kev xav tau ntawmtaub qab-welded flangesyuav tsum ua raws li cov cai hauv JB4726-4728. CovforgingsCov pa roj carbon steel los yog austenitic stainless hlau nrog nominal siab ntawm 0.25MP-1.0MPa tau teev tseg, thiab raug tso cai los tsim nrog qib Ⅰforgings. Covforgingsnrog nominal siab ntawm 1.6Mpa thiab 6.3Mpa yuav tsum ua raws li tus qauv kev cai ntawm forgings qib Ⅱ lossis siab dua. Rau flange forgings nrog nominal siab tsis tsawg tshaj li 10.0MPa, chromium molybdenum steel forgings nrog nominal siab tshaj 4.0MPa, ferrite steel forgings nrog nominal siab tshaj 1.6MPa thiab ua hauj lwm kub tsis tshaj -20 ℃, xws li ca-welded flange forgings yuav tsum tau raws li cov cov kev cai ntawm qib Ⅲ forgings. Raws li ib txwm muaj, pob tw-welded flanges yog tsim los ntawm forging lossis forging dov tshuab. Thiab yog tias siv steel phaj lossis ntu steel cov ntaub ntawv rau kev tsim khoom, nws yuav tsum ua raws li cov cai no.
Butt-welding flangeHoobkas yuav tsum mus los ntawm kev soj ntsuam ultrasonic, tshuaj xyuas yuav tsum tsis muaj stratified defects. Raws li cov kev taw qhia dov ntawm cov hlau yuav raug txiav mus rau hauv ib daim hlab, los ntawm txoj kev khoov yuav welded mus rau hauv lub voj voog, tab sis kuj yuav ua rau cov hlau nto los ua ib lub nplhaib lub tog raj kheej, tsis tuaj yeem siv cov hlau phaj cov khoom siv tshuab ua rau hauv. lub caj dab taub qab vuam flange. Rau lub pob tw welds ntawm lub nplhaib, daim ntawv ntawm kev nkag mus rau tag nrho cov vuam yuav tsum tau saws. Lub pob tw welds ntawm lub nplhaib yuav tsum raug rau kev kho cua sov tom qab vuam, thiab tib lub sijhawm, 100% xov tooj cua-kev tshuaj xyuas lossis tshuaj xyuas ultrasonic yuav tsum tau ua, thiab cov xov tooj cua-kev tshuaj xyuas yuav tsum ua raws li cov kev cai ntawm Qib II hauv wb 4730. Cov txiaj ntsig ntawm kev tshuaj xyuas ultrasonic ntawm lub pob tw-welded flange yuav tsum tau txais. Yuav tsum ua kom tau raws li cov cai ntawm chav kawm I tus qauv hauv JB4730. Butt-welded flanges yog caj dab, thaum tiaj-welded flanges tsis yog. Yog tias vim li cas kev nyab xeeb, nws yog qhov zoo tshaj los siv lub pob tw vuam. Yog tias nws yog qhov nruab nrab ib txwm, lub siab tsis siab, thiab qhov xau yuav tsis ua rau muaj kev phom sij, koj tuaj yeem xav txog kev siv cov vuam tiaj tiaj.flange.
