Hauv kev tsim kho thiab kev tsim vaj tsev engineering, cov ntaub ntawv siv tau muaj kev cuam tshuam loj rau kev ua haujlwm ntev thiab kev nyab xeeb ntawm qhov project. Ib qho khoom siv uas muaj kev hwm zoo hauv kev lag luam yog cov yeeb nkab steel, tshwj xeeb tshaj yog cov uas ua tau raws li tus qauv ASTM A252. Kev nkag siab txog tus qauv no yog qhov tseem ceeb rau cov kws tshaj lij, cov neeg cog lus, thiab cov thawj coj ua haujlwm ib yam nkaus, vim nws ua kom cov ntaub ntawv siv tau raws li cov qauv kev ua tau zoo thiab kev ua haujlwm.
ASTM A252 tus qauv npog cylindrical nominal phab ntsa steel yeeb nkab pawg tshwj xeeb. Cov pawg no yog tsim los siv los ua cov tswvcuab cov kabmob ruaj khov lossis ua vaj tse rau cov pob zeb cast-in-place. Qhov kev ua tau zoo no ua rau lawv yog ib qho tseem ceeb hauv ntau yam kev siv kev tsim kho, nrog rau cov hauv paus ntawm cov choj, cov tsev, thiab lwm cov qauv uas yuav tsum tau muaj cov hauv paus tob.
Ib qho ntawm cov ntsiab lus tseem ceeb ntawm covASTM A252, ASTM A252tus qauv yog nws tsom rau cov khoom siv ntawm cov hlau siv hauv cov yeeb nkab. Cov txheej txheem qhia txog cov kev xav tau rau lub zog tawm los, lub zog tensile, thiab elongation kom ntseeg tau tias cov hlau tuaj yeem tiv taus cov khoom thauj thiab kev ntxhov siab uas nws yuav ntsib thaum lub sijhawm ua haujlwm. Tsis tas li ntawd, tus qauv qhia meej txog cov kev siv tau rau kev sim cov khoom no, muab lub hauv paus rau kev lees paub zoo.
Hais txog kev tsim khoom, cov tuam txhab tsim cov yeeb nkab steel yuav tsum ua raws li tus qauv ASTM A252 kom ntseeg tau tias lawv cov khoom muaj kev ntseeg siab thiab nyab xeeb rau kev tsim kho. Piv txwv li, ib lub tuam txhab nrog tag nrho cov cuab tam ntawm RMB 680 lab thiab 680 tus neeg ua haujlwm tsim 400,000 tons ntawm kauv steel kav ib xyoos ib zaug nrog tus nqi tso tawm ntawm RMB 1.8 billion. Cov tuam txhab lag luam zoo li no ua lub luag haujlwm tseem ceeb hauv cov khoom lag luam, muab cov khoom zoo uas ua tau raws li cov qauv kev lag luam.
Cov txheej txheem ntau lawm ntawmsteel yeeb nkabkoom nrog ntau cov kauj ruam, suav nrog kev xaiv cov khoom siv raw, kev tsim cov yeeb nkab thiab daim ntawv thov txheej tiv thaiv. Txhua kauj ruam yuav tsum tau tswj nruj me ntsis kom ua raws li tus qauv ASTM A252. Piv txwv li, cov hlau siv yuav tsum yog los ntawm cov chaw muag khoom muaj npe uas tuaj yeem muab daim ntawv pov thawj zeb pov thawj tias cov khoom ua tau raws li qhov yuav tsum tau ua.
Tsis tas li ntawd, ASTM A252 tus qauv npog vuam thiab fabrication txheej txheem siv los tsim cov tubular pawg. Cov txheej txheem vuam kom raug yog qhov tseem ceeb rau kev tswj xyuas cov txheej txheem kev ncaj ncees ntawm cov tubular pawg, thiab cov txheej txheem muab cov txheej txheem los xyuas kom meej cov welds ua tau raug thiab xyuas kom meej.
Txhua yam, ASTM A252 tus qauv yog qhov tseem ceeb tshwj xeeb rau txhua tus neeg ua haujlwm hauv kev tsim kho kev lag luam, tshwj xeeb tshaj yog thaum nws los txog rau kev siv cov yeeb nkab steel. Kev nkag siab txog qhov yuav tsum tau ua ntawm tus qauv no yuav pab xyuas kom meej tias cov haujlwm ua haujlwm ruaj khov thiab siv cov ntaub ntawv uas yuav sawv cev rau lub sijhawm. Cov tuam txhab uas tsim cov ntaub ntawv no, xws li cov uas tau hais dhau los, ua lub luag haujlwm tseem ceeb hauv kev lag luam los ntawm kev muab cov khoom zoo uas ua tau raws li cov qauv nruj. Raws li kev tsim kho kev tsim kho txuas ntxiv mus, ua raws li cov qauv xws li ASTM A252 yog qhov tseem ceeb rau kev ua tiav hauv kev ua haujlwm.
