Hauv ntiaj teb ntawm kev tsim cov yeeb nkab steel, kev nkag siab txog kev lag luam specifications thiab cov qauv yog qhov tseem ceeb rau kev ua kom zoo thiab kev ua haujlwm. Ib qho qauv zoo li no yog ASTM A139, uas qhia txog qhov yuav tsum tau ua rau hluav taws xob fusion (arc) welded steel yeeb nkab rau kev pabcuam siab. Qhov blog no yuav ua kom tob tob rau hauv cov ntsiab lus tseem ceeb ntawm ASTM A139 thiab tshawb nrhiav nws daim ntawv thov, tshwj xeeb hauv cov ntsiab lus ntawm S235 J0 kauv steel yeeb nkab uas tsim los ntawm cov chaw tsim khoom hauv Cangzhou, Hebei Xeev.
Cov ntsiab lus tseem ceeb ntawm ASTM A139
ASTM A139 Cov khoom lag luamnpog ntau yam tseem ceeb ntawm kev tsim cov yeeb nkab steel, nrog rau cov khoom muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab cov qauv kev sim. Tus qauv tsom rau cov kev qhia hauv qab no:
1. Cov Khoom Siv Khoom Siv: ASTM A139 qhia cov tshuaj muaj pes tsawg leeg ntawm cov hlau siv los ua cov kav dej. Qhov no suav nrog cov kev txwv rau cov khoom xws li carbon, manganese, phosphorus, thiab sulfur kom ntseeg tau tias cov kav dej muaj lub zog tsim nyog thiab kav ntev.
2. Mechanical Properties: Cov qauv no qhia txog cov khoom siv tshuab uas xav tau, suav nrog lub zog tawm los, lub zog tensile, thiab elongation. Cov khoom no yog ib qho tseem ceeb los xyuas kom meej tias cov yeeb nkab tuaj yeem tiv taus cov kev siv hluav taws xob siab yam tsis muaj kev ua haujlwm.
3. Vuam yuav tsum tau: Txij li thaum ASTM A139 cuam tshuam nrog vuam kav, nws muaj xws li specifications rau cov txheej txheem vuam, nrog rau hom vuam, weld zoo, thiab cov txheej txheem tshuaj xyuas kom ntseeg tau tias cov welds ua tau raws li cov qauv xav tau.
4. Test Methods: Tus qauv kuj qhia txog cov txheej txheem xeem uas yuav tsum tau ua haujlwm los xyuas qhov zoo thiab kev ua haujlwm ntawm cov kav 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 Steel Pipe
Cov kev siv ntawm ASTM A139 steel kav yog dav thiab ntau yam, tshwj xeeb tshaj yog nyob rau hauv kev lag luam uas yuav tsum tau high-pressure piping systems. Cov kav dej no feem ntau siv rau:
- Kev lag luam roj thiab roj: ASTM A139 cov kav dej yog qhov zoo tagnrho rau kev thauj cov roj thiab roj nrog lawv lub peev xwm los tiv thaiv kev kub ntxhov thiab ib puag ncig hnyav.
- Cov Khoom Siv Dej: Qhov kav ntev thiab lub zog ntawm cov kav dej no ua rau lawv tsim nyog rau kev siv hauv cov dej thiab kev faib khoom, kom ntseeg tau cov dej ntws zoo.
- Kev Siv Tshuaj: Hauv cov nroj tsuag tshuaj, cov kav dej yuav raug rau cov tshuaj corrosive thiab ASTM A139 cov kav dej muab qhov tsim nyog tiv thaiv thiab kev ntseeg siab.
Qhov zoo ntawm S235 J0kauv steel yeeb nkab
Ib qho ntawm cov khoom zoo uas tsim los ntawm peb lub tuam txhab hauv Cangzhou yog S235 J0 kauv steel yeeb nkab. Cov khoom no tshwj xeeb tshaj yog tsim nyog rau nws yooj yim hauv txoj kab uas hla thiab phab ntsa thickness specifications. Lub adaptability ntawm manufacturing enables nws los tsim high-qib tuab-walled kav uas ua tau raws li cov kev xav tau ntawm ntau yam industries.
Founded hauv 1993, tom qab xyoo ntawm kev loj hlob sai, lub tuam txhab tam sim no npog thaj tsam ntawm 350,000 square metres, muaj tag nrho cov cuab tam ntawm RMB 680 lab, thiab muaj 680 tus neeg ua haujlwm mob siab rau, cog lus los tsim cov kav hlau zoo uas ua tau raws li cov qauv thoob ntiaj teb xws li ASTM A139.
nyob rau hauv xaus
Nkag siab txog ASTM A139 thiab nws cov lus qhia tshwj xeeb yog qhov tseem ceeb rau txhua tus neeg koom nrog hauv kev tsim cov yeeb nkab steel. Cov qauv no tsis tsuas yog ua kom zoo thiab ua haujlwm ntawm cov yeeb nkab, tab sis kuj qhib rau ntau yam kev siv thoob plaws ntau yam kev lag luam. Nrog rau cov khoom xws li S235 J0 kauv steel yeeb nkab, peb lub tuam txhab tseem ua txoj hauv kev muab cov neeg siv khoom nrog cov kev daws teeb meem zoo. Txawm hais tias koj nyob hauv kev lag luam roj thiab roj, kev siv dej lossis kev ua tshuaj, peb cov kav dej steel yuav ua tau raws li koj xav tau thiab tshaj qhov koj xav tau.
