DNV AH32 Marine Steel Phaj

Tej zaum yuav muaj qhov sib txawv hauv qab no ntawm DNV AH32 Marine Steel Phaj thiab cov phaj hlau nrog tib lub zog uas tau lees paub los ntawm lwm lub koom haum kev faib (xws li ABS AH32, LR AH32, CCS AH32):

 

Certification cov koom haum thiab specifications:

 

DNV AH32 tau lees paub los ntawm Det Norske Veritas thiab ua raws li cov cai thiab cov qauv ntawm DNV. Cov kev faib tawm sib txawv tuaj yeem muaj qhov sib txawv ntawm cov txheej txheem ntawv pov thawj, kev tswj xyuas kom zoo, cov txheej txheem tshuaj xyuas, thiab lwm yam, uas yuav ua rau qee qhov sib txawv me me ntawm cov hlau phaj nrog tib lub zog raws li cov kev faib tawm sib txawv hauv zej zog cov ntawv pov thawj. Piv txwv li, tej zaum yuav muaj qhov sib txawv ntawm qee qhov kev ntsuas kev ntsuas tshwj xeeb lossis hauv kev siv tshuaj xyuas thiab tshuaj xyuas cov txheej txheem tsim khoom.

ABS AH32 tau ntawv pov thawj los ntawm American Bureau of Shipping thiab ua raws li cov lus qhia ntawm ABS; LR AH32 tau lees paub los ntawm Lloyd's Register thiab ua raws li cov qauv ntawm LR; CCS AH32 tau ntawv pov thawj los ntawm Tuam Tshoj Kev Sib Koom Tes Sib Koom Tes thiab ua raws li cov cai ntawm CCS. Cov koom haum kev faib tawm no txhua tus muaj lawv tus kheej cov ntawv pov thawj thiab cov txheej txheem kev qhia, uas tuaj yeem cuam tshuam rau kev ua haujlwm tau lees paub thiab kev lag luam lees paub ntawm cov phiaj hlau.

 

 

 

Mechanical zog:

 

Hais txog lub zog, txawm hais tias lawv txhua tus ua tau raws li qib siab ntawm AH32, tej zaum yuav muaj qee qhov sib txawv ntawm qhov tshwj xeeb yield zog thiab tensile lub zog qhov tseem ceeb. Piv txwv li, AH32 steel phaj tau ntawv pov thawj los ntawm qee lub zej zog kev faib tawm yuav muaj lub zog ua kom muaj zog dua me ntsis, thaum lwm qhov kev faib tawm hauv zej zog yuav qis dua me ntsis, tab sis txhua yam yog nyob rau hauv qhov kev teev tseg.

Nyob rau hauv cov nqe lus ntawm toughness, qhov taw qhia xws li kev cuam tshuam toughness yuav txawv vim muaj kev faib ua pawg sib txawv. Txawv marine ib puag ncig thiab kev siv lub nkoj muaj qhov sib txawv rau qhov toughness ntawm steel phaj. Kev faib cov koom haum tuaj yeem hloov kho kom tsim nyog rau cov kev xav tau ntawm cov ntsuas toughness raws li lawv tus kheej kev paub thiab kev nkag siab ntawm kev ua lag luam.

Lwm cov cuab yeej cuab yeej ntsuas, xws li elongation thiab hardness, kuj tseem muaj qhov sib txawv me me.

 

 

 

Kev paub txog kev ua lag luam thiab kev nyiam ntawm daim ntawv thov: Hauv cov cheeb tsam sib txawv thiab kev lag luam, vim muaj keeb kwm yav dhau los, kev lag luam tus cwj pwm, kev ntseeg siab ntawm cov neeg siv khoom thiab lwm yam, cov ntawv hlau uas tau lees paub los ntawm qee lub koom haum kev faib tawm tej zaum yuav nrov dua hauv kev ua lag luam lossis muaj kev lees paub ntau dua hauv cov haujlwm tshwj xeeb. Piv txwv li, hauv qee qhov kev tsim khoom hauv nkoj hauv Tebchaws Europe thiab Tebchaws Meskas, ABS AH32 tuaj yeem nyiam dua; thaum nyob rau hauv kev lag luam hauv tsev, CCS AH32 muaj qee qhov zoo hauv qee qhov haujlwm nkoj hauv tsev. Tsis tas li ntawd, qee qhov kev lag luam nkoj loj loj tuaj yeem muaj qhov kev nyiam thiab kev siv ntau dua rau qee hom kev faib tawm hauv zej zog - ntawv pov thawj steel phaj vim muaj kev sib raug zoo ntawm kev sib raug zoo lossis cov kev cai ntawm cov haujlwm tshwj xeeb.

DNV AH32 Marine Steel Phaj yog ib qho tseem ceeb ntawm cov khoom siv hauv kev tsim khoom hauv nkoj thiab sab nrauv engineering. Hauv qab no yog cov lus qhia ntxaws txog nws:

 

Cov yam ntxwv ntawm kev ua haujlwm:

 

Lub zog siab: Nws muaj lub zog ua haujlwm siab thiab lub zog tensile, ua kom nws tiv taus ntau yam kev ntxhov siab ntawm lub nkoj thiab sab nrauv engineering cov qauv thiab ua kom muaj kev ruaj ntseg thiab kev nyab xeeb ntawm cov qauv. Nws lub zog tawm los feem ntau yog siab dua 315MPa (megapascals), thiab lub zog tensile nyob nruab nrab ntawm 440 - 570MPa.

 

Zoo toughness: Nyob rau hauv qhov hnyav marine ib puag ncig, nkoj thiab offshore engineering qauv yuav raug cuam tshuam los ntawm nthwv dej, cua daj cua dub, thiab lwm yam, yog li cov ntaub ntawv yuav tsum muaj lub zog zoo kom nqus tau lub zog thiab tiv thaiv kev tawg ntawm cov qauv. DNV AH32 steel daim hlau ua tau zoo hauv qhov no thiab tuaj yeem hloov mus rau kev ua haujlwm hauv hiav txwv nyuaj.
