Ncaj seam welded steel yeeb nkab (LSAW steel yeeb nkab), Ob chav -sided submerged arc vuam steel yeeb nkab (DSAW steel yeeb nkab), Longitudinal submerged arc welded steel yeeb nkab, siab zaus ncaj seam welded yeeb nkab
LSAW steel pipeLSAW (Longitudinal submerge arc vuam) yog ib hom SAW yeeb nkab ua los ntawm cov hlau phaj uas tau kub dov los ntawm JCOE lossis UOE txoj kev siv tshuab. JCOE thev naus laus zis sawv cev rau kev tsim thiab tsim cov txheej txheem koom nrog hauv kev tsim khoom nrog rau cov vuam sab hauv thiab sab nrauv thiab kev nthuav dav txias tom qab vuam.
Cov kav hlau steel feem ntau yog tsim los ntawm ob txoj kev tsim khoom sib txawv, uas yog cov kav dej los yog cov kav dej seamless. LSAW - longitudinal submerged arc vuam yog ib qho tshwj xeeb vuam cov txheej txheem siv nyob rau hauv zus tau tej cov welded kav, LSAW feem ntau yog cov kev daws teeb meem zoo tshaj plaws thaum ua hauj lwm tej yam kev mob yuav tsum tau siab phab ntsa thickness vim siab sab hauv los yog sab nraud siab.
Qib ntawm LSAW Steel Pipe:
Rau cov kav dej: API 5L GR A, GR.B, X42, X45, X50, X60, X60, X65, X70, X80
Rau pawg: ASTM A252 GR 1, GR 2, GR 3
ASTM A53: GR A, GR B, GR C
BS 4360: Qib 43, Qib 50
EN: S275J2H, S275J0H, S355J0H, S355J2H, S355NH, S460NH
Daim ntawv thov ntawm LSAW Steel Pipe:
Siv rau roj / roj / dej
Kev sib kis
Engineering
Offshore tej yaam num.
Thaum tsim siab - zog, siab -toughness, siab - zoo ntev - roj thiab roj pipelines, cov kav hlau uas xav tau yog feem ntau loj - txoj kab uas hla tuab - phab ntsa ncaj seam submerged arc welded kav. Raws li API cov qauv, nyob rau hauv cov kav dej loj thiab roj, thaum dhau ntawm Chav Kawm 1 thiab Chav Kawm 2 thaj chaw xws li siab - thaj chaw txias, seabeds, thiab cov neeg nyob hauv nroog loj, ncaj seam submerged arc welded kav yog tib hom yeeb nkab uas siv tau.
Qhov zoo ntawm LSAW Steel Pipes:
1) Kev ua tau zoo ntau lawm: Piv nrog cov kav ntev welded, LSAW ncaj seam welded kav muaj ntau dua efficiency.
2) Kev ruaj ntseg vuam zoo: Kev siv cov tshuab nqus dej arc vuam tuaj yeem ua kom ruaj khov ntawm vuam zoo.
3) High weld zoo: Qhov zoo ntawm qhov vuam yog siab thiab tuaj yeem ua tau raws li qhov xav tau ntau dua.
4) Haum rau loj - txoj kab uas hla welded kav: LSAW ncaj seam welded kav yog tsim rau kev tsim cov kav loj - txoj kab uas hla.
5) Kev tswj cov txheej txheem yooj yim: Piv nrog rau lwm txoj kev vuam, cov txheej txheem tswj ntawm LSAW ncaj seam welded kav yog qhov yooj yim.
Qhov ntau thiab tsawg ntawm LSAW Steel Pipe:
Loj: 16 "-72"

LSAW steel yeeb nkabKev tsim khoom:
Longitudinally Submerged Arc Welded txheej txheem ntws
LSAW (Longitudinally Submerged Arc Welded Steel kav) nyob rau hauv nplooj ntawv phaj raws li raw khoom, steel phaj nyob rau hauv pwm los yog molding tshuab siab (ntim) rau hauv kev siv ob -sided submerged arc vuam thiab flaring los ntawm ntau lawm.
LSAW txheej txheem ntawm welded yeeb nkab suav nrog UOE thiab JCOE.
UOE LSAW yeeb nkab txoj kev:
Peb txoj hauv kev tseem ceeb ntawm UOE LSAW steel yeeb nkab txoj kev tsim muaj xws li: steel phaj ua ntej-bending, U forming thiab O forming. Txhua tus txheej txheem tau txais ib daim ntawv tshwj xeeb los ua kom tiav peb cov txheej txheem ua ntej - khoov ntug ntawm cov hlau phaj, U sib sau thiab O sib sau ua ke kom deform cov hlau phaj rau hauv lub voj voog.
JCOE LSAW yeeb nkab txoj kev:
Kev sib sau: Tom qab ob peb kauj ruam ntawm stamping ntawm JC0 txoj kev tshuab, thawj ib nrab ntawm cov hlau phaj yog nias rau hauv "J" zoo, ces lwm ib nrab ntawm cov hlau phaj yog nias rau hauv "J" los ua ib tug "C" zoo, thiab thaum kawg pressurized los ntawm nruab nrab mus rau ib tug qhib "0" - zoo li lub raj yog tsim.
Cov txheej txheem tshwj xeeb ntawm LSAW steel yeeb nkab yog raws li hauv qab no:
1. Plate Probe: Qhov no yog siv rau kev tsim cov kab loj loj LSAW pob qij txha tom qab nws nkag mus rau hauv cov kab ntau lawm uas yog thawj zaug puv -board ultrasonic kuaj.
2. Milling: Lub tshuab siv rau milling ua qhov haujlwm no los ntawm ob -edged milling phaj kom ua tau raws li qhov yuav tsum tau ua ntawm lub phaj dav thiab ob sab sib npaug rau cov duab thiab qib.
3. Pre- nkhaus sab: Sab no yog ua tiav los ntawm kev siv lub tshuab ua ntej - dabtsi yog khoov ntawm lub pre-bending phaj ntug. Lub phaj ntug yuav tsum tau raws li qhov yuav tsum tau curvature.
4. Kev tsim: Tom qab ua ntej -bending kauj ruam, nyob rau hauv thawj ib nrab ntawm lub JCO molding tshuab, tom qab stamped hlau, nws yog nias rau hauv ib tug "J" zoo li thaum nyob rau lwm yam ib nrab ntawm tib steel phaj nws yog khoov thiab nias rau hauv "C" duab, ces qhov kawg qhib daim ntawv "O" zoo li.
5. Ua ntej- vuam: Qhov no yog ua kom cov yeeb nkab steel hlau ncaj nraim tom qab nws tau tsim thiab tom qab ntawd siv roj vuam seam (MAG) rau kev txuas txuas ntxiv.
6. Nyob rau hauv weld: Qhov no yog ua tiav nrog ib tug tandem multi-wire submerged arc vuam (txog plaub hlau) nyob rau hauv ib feem ntawm lub ncaj seam welded steel yeeb nkab.
7. Sab nraud Weld: Sab nraud weld yog tandem multi-wire submerged arc vuam nyob rau sab nrauv ntawm LSAW steel yeeb nkab vuam.
8. Kev Ntsuas Ultrasonic: Sab nraud thiab sab hauv ntawm txoj hlua ncaj nraim welded steel yeeb nkab thiab ob sab ntawm cov khoom siv yog welded nrog 100% kev soj ntsuam.
9. X-ray tshuaj ntsuam: X-ray industrial TV tshuaj xyuas yog ua nyob rau sab hauv thiab sab nraud siv cov duab ua kom paub tseeb tias muaj kev tshawb pom rhiab heev.
10. Kev nthuav dav: Qhov no yog rau kev ua tiav submerged arc vuam thiab ncaj seam steel yeeb nkab ntev lub qhov taub thiaj li los txhim kho cov yeeb nkab steel qhov loj precision thiab txhim kho qhov kev faib tawm ntawm kev ntxhov siab hauv cov raj steel.
11. Hydraulic test: Qhov no yog ua los ntawm hydraulic test tshuab rau steel tom qab nthuav dav los ntawm -cov hauv paus kev ntsuam xyuas kom ntseeg tau tias cov yeeb nkab steel ua tau raws li tus qauv yuav tsum tau ua nrog lub tshuab muaj cov ntaub ntawv tsis siv neeg thiab khaws cia.
12. Chamfering: Qhov no suav nrog kev tshuaj xyuas ntawm cov yeeb nkab steel thaum kawg ntawm tag nrho cov txheej txheem.
Cov khoom siv ntawm LSAW steel yeeb nkab:
Phaj ntug milling tshuab
Lub tshuab milling mills ob sab ntawm lub phaj mus rau cov qauv nruj kom ua tau raws li qhov dav, edging thiab zawj duab specifications.
Ntug crimping tshuab
Lub tshuab crimping crimps cov npoo ntawm lub phaj los ua qhov xav tau curvature.
Tack welding tshuab
Ob lub npoo ntawm qhov qhib seam yeeb nkab yog coj los ua ke los ntawm lub tshuab tack welding. ces welded los ntawm tack welder siv ib tug hlau active - gas arc vuam ("MAG") txheej txheem.
Kev tsim tshuab
Siv cov txheej txheem "JCO" los khoov thiab tsim cov phaj crimped rau hauv cov yeeb nkab steel.
Sab hauv welding tshuab
Sab hauv longitudinal seam ntawm cov yeeb nkab yog welded los ntawm sab hauv los ntawm kev kho 4 vuam taub hau thaum txav yeeb nkab thiab siv submerged - arc vuam txheej txheem.
Xaus ntsej muag tshuab
Lub tshuab theem cov yeeb nkab kawg nrog rotating cutter hau kom paub meej tias yuav tsum tau zawj thiab ntug specifications tau ntsib.
Hydrostatic Tester
Siv lub ntsej muag sealing thev naus laus zis tshem tawm cov chaw dig muag thaum lub sijhawm kuaj hydrostatic. Lub tester kuj tau nruab nrog tsis siv neeg kaw thiab khaws cia ua haujlwm.
Expanding tshuab
Cov yeeb nkab yog raug rau tag nrho -ntev nthuav dav kom nce qhov tseeb ntawm cov yeeb nkab qhov ntev thiab txhim kho qhov kev ntxhov siab sab hauv.
