Nyob rau hauv xyoo tas los no, tau muaj kev hloov pauv loj hauv kev lag luam steel kev nkag siab ntawm cov pa roj carbon steel alloys thiab lawv tsis kam tiv thaiv kev ntxhov siab corrosion. Qhov kev hloov pauv no tau ua rau muaj kev tsom mus rau qhov zoo thiab cov qauv ntawm cov yeeb nkab steel, tshwj xeeb tshaj yog cov khoom tsim rau ASTM (American Society for Testing and Materials) specifications. Cov pa roj carbon steel yeeb nkab tau ntev tau lees paub rau nws cov kav ntev thiab kev ntseeg tau, thiab nws cov ntawv pov thawj thoob ntiaj teb tsis ntev los no ntxiv dag zog rau nws txoj haujlwm raws li kev lag luam tus qauv.
Kev lig kev cai, qee cov carbon steel alloys tau raug txiav txim siab tiv thaiv kev ntxhov siab corrosion, ua rau lawv xaiv rau ntau yam kev lag luam. Txawm li cas los xij, kev txhim kho tsis ntev los no qhia tias qee qhov ntawm cov alloys no yuav ua rau muaj kev cuam tshuam rau hom corrosion. Qhov kev tshawb pom no ua rau muaj kev txhawj xeeb hauv kev lag luam thiab qhia txog qhov tseem ceeb ntawm kev tswj xyuas kev tswj xyuas zoo hauv cov yeeb nkab steel.
Teb rau cov kev txhawj xeeb no,ASTM carbon steel kavcov tuam txhab lag luam tau ua cov kauj ruam tseem ceeb los xyuas kom meej qhov zoo tshaj plaws thiab cov qauv kev ua tau zoo. Qhov kev cog lus rau kev ua tau zoo tshaj plaws hauv kev lees paub zoo thoob ntiaj teb, ua kom pom tias cov raj hlau ua tau raws li cov kev cai nruj raws li cov qauv thoob ntiaj teb. Qhov kev ua tiav no tsis tsuas yog ua kom pom cov yeeb nkab steel cov tuam txhab kev mob siab rau kev tswj cov qib siab tshaj plaws, tab sis kuj tsim ASTM steel yeeb nkab ua lub cim kev lag luam ntawm kev ntseeg tau thiab kav ntev.
Daim ntawv pov thawj zoo thoob ntiaj teb ntawm Ms steel kav yog qhov tseem ceeb rau ntau yam kev lag luam uas vam khom cov kav hlau zoo, nrog rau kev tsim kho, kev tsim kho vaj tse thiab kev tsim khoom lag luam. Los ntawm kev sib ntsib thiab dhau cov qauv zoo thoob ntiaj teb, ASTM steel yeeb nkab muab cov engineers, cov neeg cog lus thiab cov thawj tswj xyuas qhov project nrog kev lees paub tias lawv cov ntawv thov tau txais kev txhawb nqa los ntawm cov khoom siv ruaj khov thiab txhim khu kev qha.
Tsis tas li ntawd, qhov tau txais daim ntawv pov thawj zoo thoob ntiaj teb tau nce cov xwm txheej ntawm ASTM steel kav mus rau cov qauv kev lag luam. Raws li tus qauv ntsuas, ASTM steel yeeb nkab teeb tsa tus qauv zoo tshaj plaws rau lwm cov tuam txhab lag luam kom ua raws, tsav kev txhim kho tag nrho ntawm cov yeeb nkab steel zoo thiab kev ua tau zoo thoob plaws hauv kev lag luam. Qhov no tsis tsuas yog tso cai rau cov neeg siv kawg kom ntseeg siab xaivwelded steel kavrau lawv tej yaam num, tab sis kuj txhawb kev noj qab haus huv kev sib tw thiab innovation nyob rau hauv steel manufacturing kev lag luam.
ASTM steel yeeb nkab txoj kev taug kev kom ua tiav cov ntawv pov thawj thoob ntiaj teb zoo yog qhov ua pov thawj rau kev lag luam kev cog lus rau kev txhim kho txuas ntxiv thiab ua raws li cov qauv zoo tshaj plaws. Nws qhia txog qhov tseem ceeb ntawm kev ua raws li cov txheej txheem thev naus laus zis thiab txuas ntxiv txhim kho kev nkag siab ntawm cov khoom siv kom ntseeg tau tias cov yeeb nkab steel tseem nyob ntawm qhov ua ntej ntawm kev ntseeg tau thiab kev ua tau zoo.
Hauv cov ntsiab lus,steel round yeeb nkab'sKev ua tiav ntawm cov ntawv pov thawj zoo thoob ntiaj teb yog qhov tseem ceeb rau kev lag luam steel. Nws tsis tsuas yog daws cov teeb meem hloov zuj zus cuam tshuam nrog kev ntxhov siab corrosion cracking tab sis kuj ua rau cov yeeb nkab steel puag ncig
kev lag luam benchmark rau qhov zoo thiab kev ntseeg tau. Raws li kev thov kom ruaj khov thiab ua tau zoo steel yeeb nkab txuas ntxiv zuj zus, ASTM Steel Pipe cov ntawv pov thawj thoob ntiaj teb kev ua tau zoo ua rau nws txoj hauj lwm ua qhov kev ntseeg siab thiab thawj qhov kev xaiv rau ntau yam kev siv.
