Q1: Leej twg yog tus loj ntiaj teb cov tuam txhab ntawm S460NH cov yeeb nkab?
Ua cov tuam ntxhab European suav nrog Lub Tebchaws Yelemees's Salzgitter, Spain Lub qe caj dab, thiab Ltalis tus neeg taug kev. Lawv cov khoom ua raws li EN 10219 tus qauv thiab cov txheej txheem paub tab. Suav cov tuam txhab xws li baosteel thiab ansteel Cov tuam txhab Jape thiab NSSMC tuav ib txoj hauj lwm hauv siab {{6} pre} precision cool {}} tsim kav dej. Thaum kev yuav khoom, txheeb xyuas tias cov chaw tsim khoom thauj cov ped 2014/68 / EU cov ntawv pov thawj (EU cov cuab yeej qhia siab). Kev lag luam tawm xws li Is Nrias teb Tata steel kuj tseem muaj peev xwm nce ntau lawm, tab sis kev sib xws zoo tseem yuav tau txheeb xyuas.
Q2: Cov ntsiab lus tseem ceeb muaj feem xyuam S460NK cov yeeb nkab nqi?
Raw material costs (especially ferroniobium and ferrovanadium alloys) directly influence pricing. Rising niobium prices in 2023 led to a 10%-15% price increase for steel pipes. Thick-walled pipes (>30mm) command a 20%-30% premium over thin-walled pipes due to the increased difficulty of rolling. Special technical requirements (such as Z35 lamellar tear resistance) increase testing and processing costs. Ocean freight and tariffs (such as the EU CBAM carbon tariff) can also drive up import prices. Bulk purchases (>500 tons) feem ntau tau txais 5% -8% luv nqi.
Q3: Cov txuj ci tshwj xeeb yuav tsum muab ua cov khoom siv s460NH steel?
Tus qauv (xws li en 10219 - 1: 2006), qhov ntev (OD, cov kev mob tuab), thiab tswj hwm tau los ntawm dov) yuav tsum tau teev tseg. Cov kev xav tau ntxiv yuav suav nrog cuam tshuam lub zog (KV2 ntau dua lossis sib npaug ntawm 0.43%), thiab cov qib tsis sib luag), thiab theem 3 lossis RT qib 2). Rau welded qauv, sab saud rau p thiab s cov ntsiab lus (p tsawg dua lossis sib npaug lossis 0.025%, sib luag rau 0.015%) yuav tsum tau teev tseg. Cov ntawv thov tshwj xeeb (xws li cua lub zog) yuav xav CTod BTD BLACTURE cov ntaub ntawv nruj.
Q4: Lub sijhawm raug xa tawm cov khoom noj yog dab tsi rau S460NH cov yeeb nkab? Yuav ua li cas nws thiaj li luv? Cov qauv qhov ntau (piv txwv li, φ219 × 10mm) tuaj yeem xa tawm hauv 2- 4 lub lis piam (eg, × 40mm) yuav tsum tau 8-12 lub lis piam. Xaiv cov neeg muab khoom hauv zos (piv txwv li, cov neeg yuav khoom European Sourcing German hlau) tuaj yeem txuag tau ib mus rau ob lub lis piam ntawm lub sijhawm thauj khoom. Pre-ordering raw cov ntaub ntawv (piv txwv li, booking lub steel mill lub caij nyoog yob sijhawm los ntawm 30%. Cov lus txiav txim ceev tuaj yeem ua ntej nrog tus nqi sib tham nce (kwv yees li 5% -10%), tab sis qhov zoo yuav tsum tau ua kom zoo.
Q5: Kuv tuaj yeem txheeb xyuas qhov tseeb ntawm cov ntaub ntawv zoo rau S460NH cov kav dej zoo?
Yuav tsum tau tus xa khoom muab daim ntawv pov thawj khoom qub (MTC) thiab pov thawj tias cov lej kub ua cov yeeb nkab cim. Thib peb -} kev soj ntsuam cov ntaub ntawv tshaj tawm (piv txwv li, sgs / bv) yuav tsum muaj cov khoom siv tshuaj, kho tshuab, thiab cuam tshuam cov ntaub ntawv. Cov qauv tuaj yeem xa mus rau chav kuaj mob rau re {{5} Kev tshuaj ntsuam ntawm cov pa roj carbon sib npaug thiab ntsuas phoo (metallographic kev kuaj). Rau cov haujlwm loj, nws raug nquahu kom xa cov neeg ua haujlwm rau lub Hoobkas los saib xyuas ntau lawm thiab ua tim khawv cov kauj ruam ntau lawm (piv txwv li, li qub).
