Q1: Cov xwm txheej tam sim no thiab kev loj hlob ntawm cov hluav taws xob roj carbon steel hlau yeeb nkab?
The current global carbon steel pipe market shows regional differentiation characteristics: the Asia-Pacific region accounts for more than 65% of global consumption, mainly driven by infrastructure investment in China and India; the North American market tends to be stable, mainly driven by oil and gas pipeline replacement demand; the European market is growing slowly due to environmental regulations. Products are developing in the direction of high steel grade (such as API 5L X70) and large diameter (>1420mm) {{. Cov Khoom Siv Hluav Taws Xob thiab E - {} Nws tau hloov pauv ib xyoos ib zaug cov kav hlau yuav dhau los ua kev tshawb fawb thiab kev txhim kho.
Q2: Dab tsi yog qhov cuam tshuam ntawm cov roj carbon neutrality txoj cai ntawm cov pa roj yeeb nkab kev lag luam?
Cov pa roj carbon Neutrality txoj cai txhawb nqa ntau seem Txhawb nqa kev siv cov ntaub ntawv hlau raw nrog cov qauv sib piv ntawm30-50%; txhim kho cov roj carbon muaj cov roj teeb roj teeb nrog qis dua qis-kub nruj (Cookie tsawg dua lossis sib npaug} 43%); txheej thev naus laus zis tsim tawm cov chromium-dawb, thiab cov dej txheej txheem txheej txheem hloov cov kuab cov kuab tshuaj; Cov kev txhim kho hluav taws xob ua rau cov khoom siv cua tshuab cua sov ntxiv, thiab cov tuam txhab uas ua rau cov kev npaj sov tau nce mus ntev yuav tau txais cov kev npaj ntxov yuav tau txais txiaj ntsig ntev.
Q3: Cov ntsiab lus kev loj hlob rau qhov kev thov cov pa roj steel hauv cov ntawv thov tawm tshiab?
Ntau cov teb hluav taws xob yog tsim kom muaj kev txhawb ntxiv: cov kab loj-ntsa tuab-walled (φ2000mm × 40mm) rau ntug dej fais fab hluav taws xob piles; Hydrogen Zog Hloov Pipelines txhawb kev tshawb fawb thiab kev txhim kho ntawm x {4 4}} qib steel qib tiv thaiv embrittlement embritt cleel kav; Modular Vaj tse ua haujlwm txhawb nqa daim ntawv thov ntawm cov qauv yeeb nkab hloov; Cov ntaub ntawv chaw txias tshuab yuav tsum muaj cov kav dej siab welded; kev ua liaj ua teb modernization tsav tsheb tsim kev tsim cov dej ua kom zoo dua qub, kev sib txuas ntawm cov kav hlau, kev ua haujlwm ntawm cov khoom siv hluav taws xob ntxiv rau.
Q4: Cov teeb meem tseem ceeb yog dab tsi rau cov pa roj carbon hlau?
Cov kev lag luam ntawm kev lag luam triple siab: Raw cov khoom siv cov nyiaj tau los ntsuas ua rau muaj txiaj ntsig, thiab tus nqi ntawm kub-rolled saib ntawm 40% hauv 2022; Kev ua raws ib puag ncig cov nqi txuas ntxiv, thiab ulission emission emission Ecission Hloov pauv peev nyiaj rau {%}% ntawm cov nyiaj tau los; Kev ua lag luam thoob ntiaj teb ua rau muaj cov neeg ua haujlwm tsis txaus siab, thiab sim cov neeg ua haujlwm siab thiab sim ua haujlwm me me thiab nruab nrab hauv qab ciaj sia..
Q5: Dab tsi yog cov lus qhia tshiab ntawm cov pa roj carbon hlau tshuab ua ke nyob rau yav tom ntej?
Thev naus laus zis ua rau tsib thaj chaw: Cov Yeeb Nkab Yeeb Nkab Ua Yeeb Yam, xws li Kev Tswj Xyuas Kev Tshawb Fawb raws li cov tshuab siv tshuab; Kev loj hlob ntawm cov kev ua tau zoo cov qib kawm steel, suav nrog-60} Cov kav dej qis qis thiab h resist₂ corr-resistant steel kav; Cov txheej txheem ntau lawm, xws li laser rust tshem tawm tsis yog pickling pickling, thiab kev siv ntawm hydrogen rhaub cov cua sov; kev ua haujlwm ua haujlwm, xws li kev kho tus kheej kho tus kheej thiab thermal ua kom zoo dua txheej txheem txheej txheem; Tag nrho lub voj voog kev tswj, thiab kav cov kev hloov pauv ntawm cov roj carbon steel los ntawm cov khoom siv steel hlau kom muaj txiaj ntsig zoo ntxiv cov kev daws teeb meem-{9}}
