Ua kom tiav Technical Overview rau High -Quality Pipeline Production
Cov txheej txheem tsim khoom ntawm LSAW steel yeeb nkab, tseem hu ua Longitudinal Submerged Arc Welded yeeb nkab, yog tsim los tsim loj - txoj kab uas hla, tuab - phab ntsa, thiab siab - lub zog steel kav rau kev thov. Txoj kev tsim khoom no ua kom muaj qhov tshwj xeeb weld kev ncaj ncees, qhov tseeb qhov tseeb, thiab kev ua haujlwm txhua yam, ua rau LSAW cov yeeb nkab siv dav hauv cov roj thiab cov pa xa mus, cov txheej txheem sab nrauv, kev thauj mus los hauv dej, thiab cov phiaj xwm loj.
Raws li ib tug ua LSAW steel yeeb nkab chaw tsim tshuaj paus nyob rau hauv Suav teb, Huayang Steel Yeeb Nkab txais kev tsim cov cuab yeej siv siab, siab - vuam tshuab, thiab kev tswj xyuas nruj kom xa cov khoom raws li cov qauv thoob ntiaj teb xws li API 5L, ASTM, EN, GB, thiab DIN. Cov hauv qab no yog cov ncauj lus kom ntxaws txog tag nrho LSAW steel yeeb nkab txheej txheem.
1. Raw Material Inspection thiab phaj xaiv
LSAW manufacturing txheej txheem pib nrog steel daim hlau los ntawm kev ntseeg siab mills. Txhua lub phaj ua tiav kev tshuaj xyuas kom ntseeg tau tias ua tau raws li cov qauv siv tshuab thiab tshuaj lom neeg.
Cov khoom tseem ceeb ntawm kev soj ntsuam muaj xws li:
• Tshuaj muaj pes tsawg leeg
• Ntog teeb meem
• Phaj tuab thiab qhov tseeb qhov tseeb
• Ultrasonic kuaj xyuas kom paub qhov tsis zoo ntawm sab hauv
Tsuas yog daim phiaj tsim nyog tau txais kev tso cai nkag mus rau hauv txoj kab tsim.
2. Ntug Milling
Ua ntej tsim, lub phaj npoo yuav tsum tau npaj kom paub meej qhov vuam. High-cov cuab yeej milling precision yog siv los txiav thiab bevel ob lub npoo ntawm cov phaj steel rau hauv qhov xav tau vuam lub kaum ntse ntse. Qhov no tau lees tias haum zoo-up, raug kho kom raug, thiab muaj zog weld bonding.
3. Pre-Bending thiab J-C-O Forming
LSAW steel kav yog zoo li tus siv J-C-O txoj kev tsim. Cov txheej txheem no suav nrog peb theem loj:
3.1 Pre-Bending
Cov npoo ntawm lub phaj yog ua ntej- khoov kom zoo curvature thiab yog roundness.
3.2 J-Kev ua kom zoo
Lub phaj yog thawj zaug nias rau hauv J-puab siv hydraulic presses.
3.3 C-Suab txoj kev
Cov theem tom ntej ntxiv khoov lub phaj rau hauv C-puab.
3.4 Thaum kawg O-Shabed Forming
Thaum kawg, lub phaj raug nias rau hauv O-puab kaw tag, tsim cov yeeb nkab cylindrical steel.
J-C-O txoj kev tsim tso cai rau kev tswj qhov loj me thiab txawm tias muaj kev ntxhov siab, uas txhim kho kev ruaj ntseg thiab kev ua haujlwm ntawm cov khoom kawg.
4. Sab hauv thiab sab nraud Submerged Arc Vuam
Tom qab kev tsim, cov yeeb nkab tau undergoes longitudinal submerged arc vuam. Qhov no yog cov kauj ruam tseem ceeb uas txhais tau qhov zoo ntawm LSAW yeeb nkab.
4.1 Internal Weld
Submerged arc vuam yog siv rau hauv cov yeeb nkab ua ntej. Cov txheej txheem no siv granular flux los npog thaj tsam vuam, muab kev nkag mus tob thiab huv, ruaj khov weld hlaws.
4.2 Sab nraud Weld
Sab nraud weld ua raws li, kom ntseeg tau tias kev sib koom ua ke tag nrho thiab kev txhawb nqa. Nrog cov txheej txheem vuam siab, cov txheej txheem tsim:
• High weld toughness
• Tsawg porosity
• Ua kom tawg tau zoo heev
• Uniform metallurgical qauv
Txoj kev vuam no tshwj xeeb yog tsim rau siab - siab thiab ntev - kev siv cov raj xa dej.
5. Mechanical Expansion
Thaum welded, cov yeeb nkab yuav tsum tau siv tshuab nthuav dav los txhim kho nws qhov kev ruaj ntseg. Txoj kev nthuav dav muaj ntau yam txiaj ntsig:
• Txhim khu kev sib tw
• Txo cov kev ntxhov siab uas seem
• Ua kom lub cev tsis sib xws
• Txhim kho qhov sib raug zoo thaum lub sij hawm teeb tsa
6. Kev kho cua sov
Nyob ntawm qib thiab daim ntawv thov, cov kav dej LSAW tuaj yeem raug kho cov txheej txheem kub xws li normalizing lossis tempering. Cov kev kho mob no txhim kho lub toughness, ductility, thiab tag nrho cov khoom siv ntawm lub vuam seam thiab cov yeeb nkab lub cev.
7. Tsis yog-Kev kuaj kev puas tsuaj thiab kev tswj kom zoo
Kev tswj hwm nruj yog qhov tseem ceeb thoob plaws hauv tag nrho cov khoom ntws. LSAW cov kav dej raug sim siv ntau txoj hauv kev tshuaj xyuas kom ntseeg tau tias ua tau raws li qhov project specifications.
Cov txheej txheem kuaj pom
• Ultrasonic kuaj ntawm vuam thiab phaj
• X-Ray tshuaj ntsuam xyuas kev ncaj ncees
• Kev ntsuas hydrostatic siab
• Kev tshuaj xyuas qhov muag pom
Hauv qab no yog ib lub rooj me me uas qhia txog cov txheej txheem tshuaj xyuas tseem ceeb:
| Txoj kev tshuaj xyuas | Lub hom phiaj |
|---|---|
| Kev kuaj Ultrasonic | Txheeb xyuas qhov tsis xws luag hauv cov vuam thiab phaj |
| X-Ray Testing | Xyuas kom tag nrho weld nkag mus thiab zoo |
| Hydrostatic Test | Paub meej tias lub siab tsis kam thiab sealing |
| Dimensional Check | Xyuas kom txoj kab uas hla, thickness, thiab roundness raug |
Cov kev ntsuas zoo no ua kom cov khoom kawg xa tawm mus ntev - kev ntseeg siab txawm nyob rau hauv ib puag ncig hnyav.
8. Xaus Beveling thiab tiav
Tom qab dhau tag nrho cov kev tshuaj xyuas, cov yeeb nkab kawg yog beveled los npaj rau kev sib tsoo. Cov txheej txheem ntxiv muaj xws li:
• Kev tu lub ntsej muag
• Anti- txheej txheej
• Kev kuaj qhov ntev kawg
• Kev kos npe thiab ntim khoom
Txhua lub yeeb nkab tau sau nrog qhov loj me, qib, tus qauv, thiab tus naj npawb ntawm cov cua sov rau kev taug qab.
9. Daim ntawv thov ntawmLSAW steel yeeb nkab
Vim nws txoj kev ua haujlwm zoo tshaj plaws thiab tuab - phab ntsa muaj peev xwm, LSAW yeeb nkab yog siv rau ntau qhov tseem ceeb, suav nrog:
• Cov kav dej thauj roj thiab roj
• Offshore cua zog lub hauv paus pawg
• Cov kav dej thiab cov kav dej
• Cov qauv dej hiav txwv thiab ntug hiav txwv
• Kev tsim vaj tsev thiab choj
• Petrochemical pipeline networks
Nws lub zog siab, kev ntseeg siab ntawm vuam, thiab kev ua haujlwm siab zoo ua rau LSAW yeeb nkab yog kev lag luam -nyiam dua rau kev hnyav- cov ntawv thov engineering.
Xaus
Cov txheej txheem ntau lawm ntawmLSAW steel yeeb nkabsuav nrog kev tswj cov khoom siv raw, siab heev J-C-O txoj kev siv tshuab, siab- zoo submerged arc vuam, mechanical expansion, kub kho, thiab nruj soj ntsuam cov txheej txheem. Qhov kev ua haujlwm tiav no ua kom ntseeg tau tias LSAW cov kav dej tsim los ntawm Huayang Steel Pipe xa cov kev ua tau zoo tshwj xeeb hauv lub zog, kev tiv thaiv corrosion, thiab qhov raug.
Rau tej yaam num uas yuav tsum tau txhim khu kev qha, tuab -phab ntsa, loj- txoj kab uas hla pipeline kev daws teeb meem, LSAW steel yeeb nkab tseem yog ib qho kev xaiv saum toj kawg nkaus vim nws durability, structural kev ncaj ncees, thiab ua raws li thoob ntiaj teb cov qauv.
