Shipbuilding Steel Phaj yog dab tsi?
Shipbuilding steel phaj (tseem hu uamarine steel phaj) yog ib pawg tshwj xeeb ntawm siab- lub zog, qis- alloy steel tsim tshwj xeeb rau kev tsim cov nkoj hiav txwv thiab dej hiav txwv engineering. Tsis zoo li cov qauv carbon steel, shipbuilding steel yuav tsum muaj qhov tshwj xeeblow -kub toughness, corrosion kuj, thiabsuperior weldabilitytiv taus qhov hnyav marine ib puag ncig.
NtawmYUXIN Steel Group, peb muab siab -zooshipbuilding steel phajtau ntawv pov thawj los ntawm cov koom haum kev faib loj loj, ua kom muaj kev ua raws li tag nrhoASTM A131 131, API, thiabISOqauv.
Cov qib tseem ceeb: AH36, DH36, EH36, thiab ABS AH32
Xaiv qhov raugqib ntawm shipbuilding steelyog qhov tseem ceeb rau kev nyab xeeb thiab tus nqi -kev ua tau zoo. Hauv qab no yog cov tshawb nrhiav tshaj plawssiab -lub zog marine steel daim hlauntawm kev ua lag luam.
ABS AH32 Hlau Phaj
Qhov nruab nrab -lub zog steel sib npaug rau kev siv dej hiav txwv dav dav. Nws yog tus nqi -zoo thiab muaj kev cuam tshuam zoo ntawm -20 degree, ua rau nws zoo tagnrho raunkoj nkoj, bulkheads, thiablawjntawm nruab nrab- cov nkoj loj.
Yield zog:Ntau dua lossis sib npaug li 315 MPa
Qhov zoo tshaj plaws rau:General cargo nkoj, bulk carriers.
ABS AH36 / DH36 / EH36 Hlau Phaj
Qhov no yog tus qauv kev lag luam rau niaj hnub shipbuilding.AW 36muaj zog yield zog (355 MPa) dua AH32.DH 36thiabEH 36yuav tsum tau muaj rau qhov tseem ceeb ntawm cov qauv tsim thiab qis -kev ua haujlwm kub.
Yield zog:Ntau dua lossis sib npaug li 355 MPa
Impact Test:AH36 (-20 degree), DH36 (-40 degree), EH36 (-40 degree).
Qhov zoo tshaj plaws rau:Thawv nkoj, tankers, thiab offshore rigs.
ASTM A131 Qib A / B / D
Cov no yog "ib txwm muaj zog" nkoj daim hlau (Qib A yog qhov feem ntau). Lawv feem ntau yog siv rau kev sib zog ntawm cov hlab ntsha thiab kho qhov twg cov hlau tsis muaj zog tensile siab.

FAQ
01.Dab tsi yog qhov txawv ntawm ABS AH36 thiab ABS DH36 shipbuilding steel phaj?
02.Koj puas muab kev txiav thiab ua ntej- kev kho mob rau lub nkoj hull steel daim hlau?
Yog lawm. Peb nkag siab tias lub nkoj nkoj nyiam npaj tau- rau- cov khoom siv vuam. Peb muabtus nqi- ntxiv cov kev pabcuam ua haujlwmrau txhua tusshipbuilding steel phaj, suav nrog:
Plasma & laser txiavrau koj qhov luaj li cas (tolerances hauv ± 2mm)
Drillingthiab ntug kev npaj (beveling)
Kev tawg(Sa 2.5 standard) thiabkhw primer daim ntawv thov(zinc -nplua nuj epoxy, 15-25 microns)
Cov kev pabcuam no txo qis ntawm - chaw ua haujlwm thiab cov khoom pov tseg. Thov muab koj daim duab txiav (DXF lossis DWG) thiab qib xav tau (xws li,ABS AH36, LR DH 36) rau customized hais.
03.Yuav ua li cas faib cov ntawv pov thawj hauv zej zog koj tuaj yeem muab rau koj cov phiaj xwm marine steel?
Tag nrho pebshipbuilding steel phajyog muab nrogthib peb- tog tshuaj ntsuam xyuasthiab thawjMill Test Certificate (MTCs). Peb tuaj yeem muab ntawv pov thawj los ntawm txhua lub koom haum kev faib loj, suav nrog:

Yog tias koj qhov project xav tau ib lub koom haum tshwj xeeb lub cim (xws li,ABS ntawv pov thawj steel phajrau US - lub nkoj khi), peb tuaj yeem npaj rau lub zeb los muab daim ntawv pov thawj raws li. Thov qhia koj qhov yuav tsum tau ua thaum thov kev tsocai.
04.Yuav ua li cas yog tus nqi ntawm shipbuilding steel phaj xam? Koj puas muaj Tshuag ntawm AH36?
Tus nqi ntawmshipbuilding steel phajyog feem ntau xamib metric tons (USD / ton), raws li:
Qib & specification(piv txwv li, ABS AH36 vs. steel qib A)
Qhov ntev(thickness, dav, ntev) - tuab thiab dav daim hlau yuav tsum tau ntau zeb dov muaj peev xwm
Daim ntawv pov thawj xav tau(ABS / LR / DNV daim ntawv pov thawj tej zaum yuav muaj tus nqi me me)
Ntau(tag nrho cov thawv thauj khoom lossis ntau lub nkoj xaj)
Cov ntsiab lus xa khoom(FOB Tuam Tshoj, CIF koj qhov chaw nres nkoj, lossis CFR)
Yog, peb khaws cianpaj khoomntawm nrawm- cov qhab nias zoo liABS AH36, ASTM A131 Qib A, thiabDH 36nyob rau hauv thicknesses xws li los ntawm8mm rau 60mm. Rau cov khoom lag luam, lub sijhawm ua haujlwm yog7-10 hnubtom qab tso nyiaj. Rau kev cai- dov daim hlau (piv txwv li, 80mm + tuab), lub sijhawm ua haujlwm yog kwv yees li25-35 hnub. Tiv tauj peb nrog koj lub hom phiaj thickness, qib, thiab qhov chaw nres nkoj rau tib yam - hnub FOB lossis CIF nqi.
