Core Manufacturing Process (Cold forming Line)
JCOE (Feem ntau cov khaub thuas- txheej txheem tsim)
- Cov hlau phaj tuaj yeem kuaj pom → Ntug milling (beveling)
- Kauj ruam-los ntawm- kauj ruam kev ua kom txias: J- nias → C- nias → O- kev sib sau ( tshuab nias ntawm qhov kub thiab txias thoob plaws; tsis muaj cua sov)
- Ua ntej-tack welding rau qhov chaw → Ob -sided submerged arc vuam (DSAW) (sab hauv thiab sab nraud)
- Txias nthuav dav: Cov tub ntxhais txias txias- txheej txheem ua haujlwm kom tshem tawm cov kev ntxhov siab uas seem thiab ua kom muaj qhov sib npaug thiab qhov tseeb
- Weld seam UT/RT tshuaj xyuas, kuaj hydrostatic, beveling, thiab tiv thaiv- txheej txheej
UOE (Txias- txheej txheem tsim rau loj- txoj kab uas hla, siab- ntim ntau lawm)
- Hlau phaj undergoes U- nias ua raws li O-forming; Cov txheej txheem vuam txuas ntxiv thiab cov txheej txheem txias txias yog zoo ib yam rau JCOE
- Qhov tseem ceeb sib txawv:Sib txawv ntawm kub- dov coiled yeeb nkab thiab kub- dov seamless yeeb nkab; LSAW cia siab rau qhov txias txias ntawm ambient kub, li no lub npe "Cold formed"

Key Performance Advantages
- Tswj tau txias- ua kom muaj kev ntxhov siab:Cov txheej txheem kev nthuav dav txias txo cov kev ntxhov siab, ua rau tsawg kawg rau kev sib tw thiab kev ncaj.
- Qhov kev xaiv tseem ceeb tshaj plaws rau cov tuab-walled, loj- txoj kab uas hla: Tsim los ntawm ib qho nruab nrab - mus rau -hnyav phaj, muab superior haum rau siab-siab, tuab-walled kev pab cuam piv rau ERW (High-Frequency Welded) yeeb nkab.
- Ob npaug -sided submerged arc vuam (DSAW) kom ntseeg tau qhov sib sib zog nqus weld nkag thiab siab toughness; PSL2-qib ua raws li qhov yuav tsum tau ua rau huab cua txias thiab qaub roj / roj ib puag ncig.
- Siv tag nrho - cov khoom siv phaj puag yam tsis muaj steel sawb sib tshooj, ua kom cov khoom sib xws thiab zoo heev qaug zog thiab seismic tsis kam.
- Tau tshaj 3LPE, FBE, thiab thee tar epoxy anti-corrosion coatings; haum rau ntev -nruab nrab ntawm ntug dej hiav txwv thiab cov kav dej hiav txwv.
FAQ
Q: Dab tsi yog qhov txiaj ntsig tseem ceeb ntawm kev xaiv qhov txias - tsim LSAW yeeb nkab hla lub kub -extruded seamless yeeb nkab rau cov kab loj?
A: While seamless pipes excel in small-to-medium diameters, producing large-diameter (>16") hnyav-phab ntsa seamless kav yog kim heev thiab txwv los ntawm zeb loj txwv. Txias- tsim LSAW kav dej txuas qhov sib txawv no tau zoo. Los ntawm txias- ua cov hlau phaj hnyav, LSAW ua tiav ultra- txoj kab uas hla loj (txog 60" los yog ntau dua ntawm phab ntsa tuab thiab cov nqi qis dua) seamless extrusion.
Q: Qhov "Mechanical Expansion" piv li cas cuam tshuam rau lub cev lub cev ntawm cov khaub thuas - tsim LSAW yeeb nkab?
A: Mechanical expansion feem ntau nthuav cov yeeb nkab ncig los ntawm0.6% txog 1.5%. Qhov kev tswj xyuas txias ua haujlwm me ntsis nce qhov tsawg kawg nkaus lub zog ntawm cov hlau matrix los ntawm kev ua kom tawv tawv. Qhov tseem ceeb tshaj, nws normalizes residual stress gradients tsim thaum lub sij hawm phaj dabtsi yog khoov thiab longitudinal vuam, kom cov yeeb nkab nyob twj ywm zoo kawg nkaus puag ncig thiab dimensionally ruaj khov thaum lub sij hawm theem nrab txiav los yog teb welding.
Q: Dab tsi tsis yog -kev kuaj kev puas tsuaj (NDT) matrix yog tus qauv rau txias- tsim LSAW kav npaj rau cov txheej txheem tseem ceeb?
A: Txhawm rau lav 100% qhov tsis xws luag -dawb seam kev ncaj ncees, peb cov kab ntau lawm siv NDT matrix dav. Tom qab txias expansion thiab hydrostatic kuaj, 100% ntawm longitudinal seam undergoes nruam automatedKev kuaj ultrasonic (UT). Tsis tas li ntawd, cov yeeb nkab xaus thiab kho thaj chaw raug txheeb xyuas sivSiab -Kev Ntsuas Radiographic (RT/X-ray), thiab lub ntsej muag beveled raug tshuaj xyuas ntawm Magnetic Particle Inspection (MPI).
Q: Puas tuaj yeem txias -tsim LSAW kav siv tau rau qis- kub lossis dej hiav txwv daim ntawv thov yam tsis muaj kev pheej hmoo tawg?
A: Yog, kiag li. Los ntawm kev siv TMCP micro- alloyed steel daim hlau nrog nplua - cov qauv nplej, peb cov yeeb nkab txias - tsim LSAW tuaj yeem raug lees paub rau qis- qhov kub thiab txias cuam tshuam toughness. Lawv ib txwm dhau Charpy V-cov kev ntsuas cuam tshuam ntawm-20C rau -50C(absorbing 27 Joules rau 40 Joules), ua kom lawv ua raws li cov ntug dej hiav txwv cua, cov kav dej hauv qab dej hiav txwv, thiab cov qauv tsim qauv hauv Arctic.
