Nyob hauv lub ntiaj teb ntawm steel yeeb kev tsim khoom, nkag siab txog kev lag luam tshwj xeeb thiab cov qauv kev lag luam kev ua haujlwm tau zoo thiab ua tau zoo. Ib tus qauv no yog ANTM A139, uas tau qhia txog qhov yuav tsum muaj rau hluav taws xob fusion (arc) welded steel yeeb nkab rau cov kev pab cuam kub siab. Cov blog no yuav siv sijhawm sib sib zog nqus rau hauv cov ntsiab lus tseem ceeb ntawm S235 Japal Steel Yeeb tau tsim los ntawm cov chaw tsim khoom hauv Cangzhou, Hebei xeev.
Main Specifications ntawm ASTM A139
ASTM A139Yuav tsum tau muaj ntau yam tseem ceeb ntawm kev siv yeeb nkab steel, suav nrog cov khoom muaj pes tsawg leeg, cov cuab yeej siv neeg kho mob, thiab cov qauv ntsuas. Tus qauv tsom rau cov lus qhia hauv qab no:
1. Cov khoom siv muaj pes tsawg leeg: ASTM A139 qhia meej txog cov tshuaj lom neeg muaj pes tsawg leeg los ua cov kav dej. Qhov no suav nrog kev txwv rau cov khoom xws li carbon, mangelese, phosphorus, thiab leej faj los xyuas kom cov kav dej muaj lub zog tsim nyog thiab kav ntev.
2. Cov Khoom Siv Cov Neeg Kho Tshuab: Cov qauv no qhia cov cuab yeej xav tau, suav nrog lub zog muaj zog, lub zog tensile, thiab elongation. Cov khoom no tseem ceeb heev rau kom ntseeg tau tias cov yeeb nkab tuaj yeem tiv thaiv cov ntawv thov siab siab yam tsis muaj kev ua tsis tiav.
3. Vuam cov kev xav tau: txij li Astm A139 deals nrog cov vuam vuam, nws suav nrog hom vuam, suav nrog hom kev siv weld, suav nrog cov qauv weld, nrog rau cov ntawv sau ua kom raws li cov qauv kev pab tau.
4. Kuaj txoj kev: Tus qauv tseem paub cov qauv ntsuas uas yuav tsum tau ua haujlwm los xyuas qhov zoo thiab ua haujlwm ntawm cov raj xa dej. Qhov no suav nrog kev sim tshuaj ntsuam tsis yog los txhawm rau txhawm rau txhawm rau txhawm rau cov tsis xws hauv cov ntaub ntawv hauv kev lag luam lossis cov ntawv xa dej.
Daim Ntawv Thov ntawm Astm A139 Cov Yeeb Nkab Hlau
Cov kev siv ntawm ASTM A139 steel kav yog dav thiab ntau yam, tshwj xeeb tshaj yog nyob rau hauv kev lag luam uas xav tau kev lag luam tshuab siab. Cov kav pipes no feem ntau siv rau:
- Roj thiab roj kev lag luam: ASTM A139 kav yog qhov zoo tagnrho rau kev thauj cov roj thiab roj nrog lawv lub peev xwm los tiv thaiv qhov siab siab thiab txo cov kev mob ib puag ncig.
- Dej khoom siv cov tshuab: lub durability thiab lub zog ntawm cov kav dej ua rau lawv haum rau kev siv hauv cov dej mov thiab faib khoom siv tau yooj yim.
- Kev ua yeeb yam tshuaj lom neeg: hauv cov nroj tsuag tshuaj lom neeg, cov kav dej yog raug rau cov tshuaj xeb thiab astm A139 kav xa cov khoom lag luam tsim nyog thiab kev ntseeg tau.
Qhov Zoo Ntawm S235 J0Muab Kauv Steel Yeeb Nkab
Ib qho ntawm cov khoom lag luam zoo tshaj plaws tsim los ntawm peb lub tuam txhab hauv Cangzhou yog S235 J VAUV STEEL YEEB. Cov khoom no tau tshwj xeeb tshaj yog tsis yog qhov tshwj xeeb rau nws cov kev hloov pauv ntawm txoj kab uas hla thiab cov phab ntsa tuab cov lus qhia. Qhov yoog tau ntawm kev tsim khoom lag luam ua rau nws tsim cov qib tuab tuab tuab-phab ntsa uas tau ntsib ntau yam kev lag luam.
Tsim tau nyob rau xyoo 1993, tom qab xyoo ntawm kev loj hlob sai, muaj cov khoom siv square, muaj tag nrho cov cuab yeej ua haujlwm ntawm cov neeg ua haujlwm zoo li cov qauv hlau zoo li no Raws li istm A139.
Hauv kev xaus
Nkag Siab ATM A139 thiab nws cov lus qhia tshwj xeeb yog qhov tseem ceeb rau txhua tus neeg koom nrog Steel Yeeb Raug. Tus qauv no tsis tsuas yog ua kom muaj kev ua tau zoo thiab ua tau zoo ntawm cov yeeb nkab, tab sis kuj qhib ntau cov ntawv thov hla ntau yam kev lag luam. Nrog cov khoom lag luam xws li S235 J0 kauv steel yeeb nkab, peb lub tuam txhab txuas ntxiv ua txoj hauv kev hauv kev muab cov neeg siv khoom siv nrog cov kev daws teeb meem zoo. Txawm hais tias koj nyob hauv cov roj thiab roj kev lag luam lossis siv tshuaj lossis siv tshuaj lom neeg, peb cov kav dej yuav ua tau raws li koj cov kev xav tau thiab tshaj qhov koj xav tau.
