Q1: Hauv cov kab ke engineering txhua Q390 cov yeeb nkab steel muaj cov txiaj ntsig zoo?
Q390 cov yeeb nkab steel tau dav hauv cov tshuab hnyav (xws li crane tawg paj, excavator qauv) vim tias nws lub zog siab tuaj yeem txo qhov hnyav ntawm cov khoom siv hnyav. Q390 cov yeeb nkab steel yog siv rau hauv cov hniav txuas ntxiv (xws li cable-nyob txuas hniav thiab txuas hniav kom raug txim. Cov raj tub ntxhais tseem ceeb thiab Truss qauv ntawm cov tuam tsev siab siv Q390 txhawm rau txo cov roj av siv. Q390 kuj tseem siv tau rau cov twj xa hluav taws xob siab thiab reactor txhawb kev txhawb nqa hauv petrochemical teb. Tsis tas li ntawd, cov cuab yeej siv hnyav xws li cua tshuab raj thiab cov platform ntug dej kuj tseem cia siab rau lub zog siab thiab tawv ntawm Q390.
Q2: Vim li cas Q390 cov yeeb nkab steel nyiam rau cua tshuab raj?
Cua Turbine yees yuav tsum tau tiv thaiv cov hluav taws xob loj loj ntawm Q390 (tawm los ntau dua lossis sib npaug ntawm 390MPA) tuaj yeem txo cov phab ntsa tuab thiab hnyav. Nws cov khoom siv qis qis-kub zoo (Q390d / e) kev hloov pauv mus rau cov huab cua txias heev nyob rau sab qaum teb thiab txwv tsis pub hla brittle. Cov Z-kev taw qhia kev ua tau zoo (Z15) yuav tsum muaj cov hlau phaj kom ntseeg tau tias muaj peev xwm tawm ntawm lamellar. Zoo heev Vuam kev ua tau zoo, haum rau on-sortigrrongential vuam kev tsim kho. Cov tshuaj tiv thaiv corrosion sib xyaw ua ke nrog Q390 substrate los txuas txoj kev pabcuam lub neej ntawm lub pej thuam.
Q3: Cov khoom thov ntawm Q390 kav dej hauv cov choj engineering?
Cov nqaj hlau thiab cov nqaj tseem ceeb ntawm cov choj txuas ntxiv Q390 cov kav dej ua kom txo qis ntawm cov qauv ntawm cov qauv thiab nce cov lus luv. Nws cov txiaj ntsig zoo zog (ntau dua lossis sib npaug zos rau 390MPA) ua kom cov khoom xa tawm ntawm tus choj. Qhov qis-kub nyuaj ntawm Q390D / e ua kom muaj kev nyab xeeb ntawm cov choj nyob rau sab qaum teb (xws li Northeast thiab Northern Europe). Hauv cov raj hlau qhob tshuab Txoj kev vuam yuav tsum tau nruj me ntsis thaum kev tsim kho thaum tsim kev ntxhov siab ntawm kev cuam tshuam lub zog ntawm tus choj.
Q4: Vim li cas yog Q390 qib qib yeeb nkab siv rau cov roj thiab roj pipelines?
Cov Roj Roj Siab Roj Pipelines (xws li X56 / x60 sib npaug) yuav tsum muaj lub zog siab ntawm Q390 kom tau txais kev sib zog sab hauv siab. Nws cov vuam zoo kev ua tau zoo yog haum rau on-sorte sib ceg vuam ntawm cov kav ntev ntev. Hauv cov dej num qis (xws li Arctic Projections), Qhov kev cuam tshuam nyuaj ntawm Q390D / e zoo dua li cov raj xa dej zoo nkauj. Kev ua yeeb yam ntawm hydrogen-inducts cracking (hic) kuj yuav tsum tau raws li qhov yuav tsum tau ntawm Nace TM0284 tus qauv. Hais txog kev lag luam, Q390 yog qhov pheej yig dua li cov hlau siab dua-qib hlau (xws li x70) thiab haum rau nruab nrab thiab siab-siab xa xov tooj hluav taws xob.
Q5: Dab tsi yog cov ntawv thov q390 ntawm cov kav hlau hauv tsev?
Q390 cov yeeb nkab steel trusses yog siv nyob rau hauv cov qauv loj (xws li tshav dav hlau qhuav) kom txo cov kab ntawv txhawb nqa. Hauv cov vaj tse modular, Q390 cov yeeb nkab steel ua tiav kev ua kom sai thiab muaj peev xwm muaj peev xwm loj. Hauv kev coj seismic, qhov siab ductility ntawm Q390 tuaj yeem nqus cov seismic thiab txhim kho kev nyab xeeb hauv tsev. Hauv qab cov qauv ntawm cov tsev ntsuab, lub zog siab ntawm Q390 txo cov hlau siv thiab txo cov roj carbon monissions. Composite qauv (xws li cov raj steel
