Hauv Niaj hnub nimno Steel Yeeb Raug, Longitudinally Welded Kav (LSWWUDELLY Welded (LSW) yog dav siv rau lawv cov leeg weld zoo, thiab ruaj khov qauv. Cov kav dej no yog qhov tseem ceeb hauv cov nplais thiab cov tsheb thauj mus los, tsim qauv qauv, kev tsim kho, thiab cov pawg. Nyob ntawm daim ntawv thov thiab cov kev qhia tshwj xeeb, cov txheej txheem ntau lawm yog ua haujlwm- - zaus vuam (HFW). Hauv qab no yog cov ncauj lus kom ntxaws piav qhia txog ob qho txheej txheem.
1. Submerged arc vuam (Lsaw) - Qhov zoo tagnrho rau cov loj- txoj kab uas hla, siab- lub zog steel kav
1.1 Khoom npaj thiab ua ntej - kev kho
Kev tsim lsaw pipes pib nrog kev soj ntsuam kev ua tau zoo ntawm cov phiaj hlau. Txhua lub phaj inegegoes puv ultrasonic kuaj kom kuaj tau xws li cov kab nrib pleb lossis kev suav nrog. Tom qab tshuaj xyuas, lub phaj phaj yog milled siv ib qho ntug milling tshuab kom tau raws li qhov xav tau dav, thiab bevel duab, ua kom meej meej weld kev npaj.
1.2 precision sib sau thiab vuam
Lub milled daim hlau yog ua ntej - bent los ua kev curvature ntawm ob sab. Tom qab no cov phiaj no tau pub rau hauv JO POADE THAWJ XOVXWM, qhov chaw uas lawv muaj nyob rau hauv ib sab, tom qab ntawd sau ib qho, tom qab ntawd ua ib qho qhib "o" {{} Daim yeeb nkab lub cev. Cov yeeb nkab qhib yog ib lub raj welded siv roj (hlau nquag roj) vuam, taug kev los ntawm multi {}}}}} ob sab hauv thiab sab nraud. This technique, using up to four wires simultaneously, ensures strong, uniform welds suitable for large-diameter, load-bearing pipes.
1.3 Kev Soj Ntsuam Zoo thiab Xov Xwm
Tom qab vuam, cov kev ntsuas thiab kev kho yog nqa tawm:
- Thawj zaug ultrasonic kuaj ntawm Weld Seam thiab nyob ib sab ntawm cov khoom siv hauv paus
- X - Kev kuaj xyuas kev tshav ntuj los txheeb xyuas kev sib tw Weld sab hauv
- Txoj kab uas nthuav tawm txhim kho kev ncig thiab qhov chaw raug
- Hydrostatic kuaj kom ntsuas lub zog thiab nruj
- Sizing thiab txiav kom tau raws li cov neeg siv khoom specifications
- Thib ob puag ncig ultrasonic thiab x {{{{{{{{{{{} Ray sim kuaj, nrog rau kev sib nqus particetting ntsuas ntawm cov yeeb nkab xaus
- Sab nraud anti - corrosion kev kho, xws li epoxy hmoov lossis 3-txheej pe no alstating
LSAW cov kav dej uas ua dhau los ntawm cov txheej txheem no muaj lub zog siab thiab kev ntseeg tau, ua rau cov kua siab high {- lub luag haujlwm siv.
2. Siab - zaus vuam (Hlob) - Ua tau zoo thiab zoo tshaj plaws rau me me - txoj hauj lwm uas hla hla
2.1 txoj ntsiab cai ntawm high- zaus induction induction
High - zaus vuam yog hom kev sib tw vuam (lossis qhov cuam tshuam nrog cov tawv nqaij sib tw) uas siv cov nyhuv hluav taws xob, cov khoom cua sib thooj, thiab cua sov. Cov ntsiab cai no tau kub ua kom sov lub steel sawb sawv mus rau lub xeev molten. Ib txheej ntawm lub siab rollers ces nyem lub rhuab sawv ua ke, ua rau qoob loo qoob loo fusion thiab tsim ua ke muaj zog, huv taub hau wandd. Tus txheej txheem no tsis tas yuav tsum muaj cov khoom siv ua ke, muaj tsawg heev, thiab tsim lub tshav kub nqaim {}} be} cuam tshuam thaj chaw nrog cov khoom siv neeg kho tshuab zoo nkauj.
2.2 Cov txheej txheem streamled thiab kev tsim muaj zog ntau lawm
ERW yog tsuas yog siv rau kev tsim cov nruab nrab thiab me- txoj kab uas hla ntawm txoj kab uas hla hla hla. Tus txheej txheem suav nrog:
- Uncoiling thiab leveling ntawm steel sawb
- Nruam kev sib txuas ua ke rau hauv ib puag ncig cov yeeb nkab dawb paug ntawm cov yob txoj kev
- Induction Cua Sov ntawm Weld Erdges
- Nias lub npoo ua ke siv nyem yob
- Txias, sizing, txiav mus ntev
- Inline Weld Testing
Piv rauLsaw, HlobYog nrawm dua, ntau lub zog -} paated - zoo tagnrho cov phiaj xwm ntau lawm thiab kev tswj hwm tus nqi ntau lawm. Nws yog dav siv rau hauv cov qauv tubing, cov kua thauj, tsheb tsheb tubing, thiab kev siv tshuab.
