EH 32

 

Lub zog: Muaj lub zog tawm los uas ua tau raws li qhov yuav tsum tau ua rau EH32 kev faib tawm.

Toughness: Tsim nyog toughness rau shipbuilding daim ntaub ntawv, nrog rau kev tsom mus rau tej yam tej yam kev mob.

 

 

AW 32

 

Lub zog: Lub zog tawm los yog kwv yees li 315 MPa, ua rau nws tuaj yeem nqa cov khoom thauj thaum lub nkoj ua haujlwm.

Toughness: Zoo ductility thiab toughness.

 

 

AW 40

 

Lub zog: Lub zog muaj zog ntau dua (nyob ib ncig ntawm 390 MPa) piv rau lwm qib.

Toughness: Khaws cov khoom zoo toughness.

 

 

DH 32

 

Lub zog: Ua tau raws li qhov yuav tsum tau muaj zog rau DH32.

Toughness: Tau txhim kho toughness, tshwj xeeb tshaj yog nyob rau hauv qis kub.

 

 

DH 36

 

Lub zog: Zoo ib yam li lwm cov qib, nrog lub zog yield zog.

Toughness: Ntau dua toughness piv rau qee qib, tshwj xeeb tshaj yog nyob rau qhov kub thiab txias.

 

 

DH40

 

Lub zog: High yield zog.

Toughness: Superior toughness, tshwj xeeb tshaj yog nyob rau hauv qis kub.

 

 

EH 40

 

Lub zog: Cov khoom siv muaj zog nrog lub zog ua haujlwm siab.

Toughness: Zoo toughness, tshwj xeeb tshaj yog rau kev thov.

 

FH 36

 

Lub zog: Ua tau raws li qhov yuav tsum tau muaj zog rau FH36.

Toughness: Nws muaj zog heev.

 

 

Specification peb muab:

Thickness	2-200 hli
Dav	1000-4000 hli

Cov qauv tsim khoom thiab cov lus qhia tshwj xeeb ntawm nkoj tsim steel phaj txawv ntawm lub teb chaws mus rau lub teb chaws thiab cheeb tsam rau cheeb tsam. Cov hauv qab no yog ib co qauv thiab specifications:

 

Suav Standards:

 

GB/T 712 - 2022: "Structural Steels - Structural Steels for Ships and Offshore Structures", uas qhia txog cov qauv kev sawv cev, kev txiav txim cov ntsiab lus, qhov ntev, cov duab, qhov hnyav, kev xav tau, cov qauv kev sim, kev soj ntsuam xyuas, ntim, cim thiab daim ntawv pov thawj zoo ntawm structural steels rau nkoj thiab offshore qauv. Piv txwv li, nws ua cov ncauj lus kom ntxaws txog cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, lub xeev xa khoom, thiab lwm yam ntawm cov npe sib txawv xws li AH32, DH36, thiab EH40 ntawm shipbuilding steel daim hlau.

GB/T 5312 - 2009: "Carbon - Manganese Steel Seamless Steel Pipes", uas muaj feem xyuam rau cov pa roj carbon - manganese steel seamless steel kav rau cov nkoj thiab standardizes qhov ntev, puab, qhov hnyav, kev xav tau, kev xeem, kev soj ntsuam xyuas, lwm yam ntawm cov yeeb nkab steel. Nws yog ib qho khoom siv sib xws hauv lub nkoj lub raj xa dej.

 

International Standards:

 

ASTM A131: Tus qauv tsim los ntawm American Society for Testing and Materials (ASTM) muaj feem xyuam rau cov pa roj carbon steel thiab siab - lub zog qis - alloy steel phaj, ntu thiab strips rau cov qauv nkoj. Nws stipulates cov tshuaj muaj pes tsawg leeg, mechanical zog, dimensional tolerances, nto zoo, thiab lwm yam ntawm cov ntaub ntawv.

TS EN 10225: Cov txheej txheem European npog cov txheej txheem kev cai rau cov hlau phaj rau cov qauv sab nrauv, nrog rau cov kev cai ntawm lub zog, tawv, vuam kev ua tau zoo, corrosion kuj, thiab lwm yam. Nws yog dav siv nyob rau hauv cov teb chaws Europe thiab lwm cheeb tsam uas paub txog cov qauv no.
