ASTM A500 thiab ASTM A513yog ob qho qauv rau kev tsim cov yeeb nkab hlau los ntawm cov txheej txheem ERW.
Txawm hais tias lawv sib koom qee cov txheej txheem tsim khoom, lawv txawv ntau heev hauv ntau txoj kev.
Hom hlau
ASTM A500Cov Qauv Txheem rau Cov Yeeb Nkab Carbon Steel Uas Tau Tsim Los Ntawm Txias Thiab Tsis Muaj Qhov Txuas Hauv Cov Puag Ncig Thiab Cov Duab
ASTM A500 tsuas yog tuaj yeem ua cov hlau carbon xwb.
ASTM A513Cov Qauv Txheem rau Cov Kav Hlau Carbon thiab Alloy Steel Uas Muaj Hluav Taws Xob Tiv Thaiv
ASTM A513 tuaj yeem yog cov hlau carbon lossis cov hlau alloy.
Qhov Loj Ntau Yam
Cov Txheej Txheem Tsim Khoom
ASTM A500 Kev Tsim Khoom Txheej Txheem
Cov kav dej yuav tsum tau ua los ntawm ib tugseamless los yog vuam txheej txheem.
Cov kav dej welded yuav tsum ua los ntawm cov hlau tiaj tiaj los ntawm cov txheej txheem hluav taws xob-resistant-welding (ERW).
A500 feem ntau yog ua los ntawm cov hlau hauv lub xeev kub-kuav, tom qab ntawd txias-tsim thiab welded.
Lus Cim: Tiaj tiaj tiaj yog hais txog cov txheej txheem ua hlau uas feem ntau siv rau hlau thiab lwm yam khoom siv hlau.Hauv cov txheej txheem no, cov hlau pib hauv nws daim ntawv loj thawj (piv txwv li ingot) thiab raug flattened rau hauv cov ntawv lossis coils los ntawm kev kub lossis txias dov txheej txheem.
ASTM A513 Kev Tsim Khoom Txheej Txheem
Cov kav dej yuav tsum tau ua los ntawm cov txheej txheem hluav taws xob-tsis kam-welded thiab yuav tsum tau ua los ntawm cov hlau kub- lossis txias-kuav raws li tau teev tseg.
Kev Kho Mob Kub
ASTM A500 Kev Kho Mob Kub
Cov raj hauv tus qauv ASTM A500 feem ntau tsis xav tau kev kho cua sov. Qhov no yog vim ASTM A500 yog tsim los rau kev siv cov qauv, qhov twg qhov tseem ceeb yog nyob rau ntawm lub zog thiab kev tawv ntawm cov qauv. Cov raj no feem ntau yog tsim los ntawm kev tsim txias thiab tom qab ntawd vuam, siv cov khoom siv carbon steel uas twb muaj qee lub zog thiab kev tawv.
Txawm li cas los xij, nyob rau hauv qee kis tshwj xeeb, txhawm rau kom ua tiav cov khoom siv kho tshuab tshwj xeeb lossis kom ua tau raws li cov kev cai tshwj xeeb, cov raj thiab cov kav dej ntawm ASTM A500 yuav raug rau kev kho cua sov kom zoo lossis txo kev ntxhov siab, tshwj xeeb tshaj yog qhov twg cov kev ntxhov siab seem raug tshem tawm tom qab vuam.
ASTM A513 Kev Kho Mob Kub
Tus qauv ASTM A513 muaj ntau hom raj, qee qhov yuav raug kho cua sov kom ua tiav cov khoom siv kho tshuab xav tau.
NA(Tsis Annealed) - Tsis annealed; hais txog cov yeeb nkab hlau uas tsis tau kho cua sov hauv qhov welded lossis kos duab, piv txwv li, nws tseem nyob hauv nws qhov qub tom qab welding lossis kos duab. Kev kho no yog siv rau cov ntawv thov uas tsis xav tau kev hloov pauv hauv cov khoom siv kho tshuab los ntawm kev kho cua sov.
SRA(Kev Txo Kev Nyuaj Siab Annealed) - Kev Txo Kev Nyuaj Siab Annealing; qhov kev kho cua sov no yog ua tiav ntawm qhov kub qis dua qhov kub tseem ceeb ntawm cov khoom siv, nrog lub hom phiaj tseem ceeb ntawm kev tshem tawm cov kev ntxhov siab sab hauv uas tsim thaum lub sijhawm ua cov raj, yog li txhim kho kev ruaj khov ntawm cov khoom siv thiab tiv thaiv kev hloov pauv tom qab ua tiav. Kev txo kev nyuaj siab annealing feem ntau yog siv rau hauv kev ua cov khoom raug kom ntseeg tau tias muaj qhov ntev thiab cov duab raug.
N(Normalized los yog Normalized Annealed) - Normalized los yog normalized annealing; kev kho cua sov ntawm qhov kub siab tshaj qhov kub tseem ceeb ntawm cov khoom siv uas qhov loj ntawm cov hlau tuaj yeem ua kom huv si thiab nws cov khoom siv kho tshuab thiab kev tawv zoo dua. Normalizing yog kev kho cua sov uas siv los txhim kho cov khoom siv kho tshuab ntawm cov khoom siv kom nws tsim nyog rau cov haujlwm ua haujlwm siab dua.
Cov Tshuaj Lom Zem thiab Cov Khoom Siv Kho Tshuab
ASTM A500 tubing yog tsim los rau cov hom phiaj kev tsim kho thiab muaj cov khoom siv kho tshuab (tensile zog, yield zog, elongation) thiab tshuaj lom neeg.
Nws paub txog nws qhov kev vuam zoo thiab ductility thiab tuaj yeem siv rau hauv cov qauv uas xav tau qhov sib piv ntawm lub zog thiab qhov hnyav.
Muaj ntau hom ASTM A513 tubing sib txawv, txhua tus muaj nws cov khoom siv kho tshuab thiab tshuaj lom neeg rau cov ntawv thov tshwj xeeb.
Piv txwv li, Hom 5 tubing yog ib yam khoom rub tes (DOM) uas muaj kev kam rau siab dua, qhov chaw tiav zoo dua, thiab cov khoom siv kho tshuab zoo dua.
Cov Cheeb Tsam Tseem Ceeb
ASTM A500 feem ntau siv rau hauv cov qauv xws li cov tsev, cov choj, thiab cov khoom txhawb nqa. Nws yog siv rau qhov chaw uas xav tau lub zog siab dua thiab kev tsim kho ruaj khov.
ASTM A513, ntawm qhov tod tes, yog siv rau hauv cov ntawv thov uas xav tau kev kam rau siab thiab qhov chaw tiav. Cov kev siv feem ntau suav nrog cov khoom siv hauv tsheb thiab cov khoom siv kho tshuab uas yuav tsum tau teeb tsa ua ke nrog kev ua kom raug heev.
Nqe
Cov khoom ASTM A500 feem ntau pheej yig dua vim yog qhov yuav tsum tau ua kom raug qhov ntev ntawm cov txheej txheem tsim khoom.
ASTM A513, tshwj xeeb tshaj yog Hom 5 (DOM), tuaj yeem kim dua vim yog qhov kev siv tshuab ntxiv uas xav tau rau qhov raug zoo dua thiab qhov ua tiav ntawm qhov chaw.
Yog li ntawd, qhov kev xaiv ntawm ob hom yeeb nkab hlau no yuav tsum yog raws li qhov xav tau tshwj xeeb ntawm qhov project.
Yog tias qhov project xav tau lub zog thiab kev ruaj khov ntawm cov qauv, ASTM A500 yog qhov kev xaiv zoo dua. Yog tias, rau cov ntawv thov uas xav tau kev ua haujlwm raug thiab qhov chaw zoo heev, ASTM A513 yuav zoo dua.
Cov Cim Npe: ASTM a500 vs a513, astm a500, astm a513, cov yeeb nkab carbon steel.
