Kev tsim khoom
- Txias txoj kev
Cov phaj hlau tau hloov zuj zus mus rau hauv cov duab tubular ntawm qhov kub thiab txias siv JCOE lossis UOE tuag (tsis muaj cua sov rau qhov kub ntawm recrystallization). Tom qab tsim, cov yeeb nkab tau dhau ob -sided submerged arc vuam thiab tej zaum yuav raug nthuav dav rau qhov kawg sizing.
- LSAW=Longitudinal Submerged Arc Welded
Longitudinal seam submerged arc vuam featuring tsis siv neeg sab nraud submerged arc vuam thiab ib qho longitudinal weld seam.
Kev nkag siab txog qhov txias txias- ua ntu zus pab pawg engineering thiab kev yuav khoom ntsuas cov khoom siv ncaj ncees thiab kev ntxhov siab ntawm LSAW steel kav:
- Progressive Cold-Molding (JCOE/UOE Txheej Txheem):Heavy structural steel daim hlau yog zoo li tus nyob rau hauv ambient kub siv high -tonnage hydraulic presses rau hauv "J", "C", "O", thiab "E" qhib- yeeb nkab geometry. Ua cov duab tsim yam tsis muaj thermal input siab khaws cov microstructural grain refinement tiav thaum lub sij hawm thermo-mechanically tswj ua (TMCP) ntawm steel phaj zeb.
- Ob chav -Sided Submerged Arc Vuam (DSAW):Lub seam ntev yog welded sab hauv thiab sab nraud siv ntau -wire submerged arc vuam. Submerged nyob rau hauv ib tug tiv thaiv granular flux txheej, qhov sib sib zog nqus - weld kab sib sib zog nqus tsim cov khoom molecular daim ntawv cog lus yam tsis muaj kev pheej hmoo ntawm oxidation los yog atmospheric paug.
- Mechanical Cold Expansion & Stress Equalization:Tom qab longitudinal welding, 100% ntawm cov yeeb nkab ntev ua tiav puv - lub cev mechanical expansion. Qhov no tseem ceeb heev - kauj ruam ua hauj lwm neutralizes residual dabtsi yog khoov stresses, kho me ntsis ovality, thiab tsim kom nruj txoj kab uas hla (OD) concentricity nyob rau hauv tag nrho cov yeeb nkab ntev.
JCOE Production Process
Main Standard (Brisk Steel)
- API 5L PSL1 / PSL2 (kab yeeb nkab rau roj thiab roj, X42–X70 / X80)
- ASTM A252, ASTM A252
- TS EN 10217 Cov kav dej rau lub hom phiaj siab)
- EN 10219 / EN 10210 (Rau cov qauv siv)
- ASTM A53 (rau cov kav dej)
Qhov zoo ntawm LSAW Pipe
- Txias tsim shaping kom zoo heev roundness & nruj qhov ntev kam rau ua
- Ob chav -sab submerged arc vuam, puv weld nkag, ruaj khov weld kev ua tau zoo
- Haum rau loj txoj kab uas hla & hnyav phab ntsa tej yaam num
- Kev xaiv txias nthuav dav kom tso tawm qhov kev ntxhov siab seem

FAQ
Q: Dab tsi yog Cold formed LSAW steel yeeb nkab?
A: Cold Formed LSAW (Longitudinal Submerged Arc Welded) yeeb nkab yog tsim los ntawm JCOE / UOE txheej txheem txheej txheem txias nrog steel phaj ntawm qhov kub thiab txias, ces muab ob npaug rau -sided submerged arc vuam. Nws tseem yog lub npe hu ua SAWL yeeb nkab, dav siv rau loj - txoj kab uas hla hnyav - phab ntsa pipeline thiab structural tej yaam num.
Q: Koj puas tuaj yeem muab cov tshuaj tiv thaiv -corrosion txheej?
A: Yog. Kev xaiv: dub vanish, kub dip galvanized, FBE, 3LPE, 3PP sab hauv & sab nrauv txheej.
Q: Puas muaj kev nthuav dav txias?
A: Xaiv qhov kev kho mob txias kom tshem tawm cov kev ntxhov siab uas seem thiab txhim kho kev sib tw rau cov kav dej nruj.
Q: Koj qhov kev txiav txim yam tsawg kawg nkaus yog dab tsi?
A: MOQ 25 tons rau Brisk Steel Hoobkas.
