ASTM A500 thiab ASTM A513yog ob qho tib si qauv rau kev tsim cov yeeb nkab steel los ntawm cov txheej txheem ERW.
Txawm hais tias lawv qhia qee cov txheej txheem tsim khoom, lawv sib txawv hauv ntau txoj hauv kev.
Hom hlau
ASTM A500 1: Txheem Specification rau Cold-Formed Welded thiab Seamless Carbon Steel Structural Tubing nyob rau hauv Rounds thiab Shapes
ASTM A500 tsuas yog carbon steel xwb.
ASTM A513 Cov Lus Qhia Tshwj Xeeb: Standard Specification for Electric-Resistance-Welded Carbon thiab Alloy Steel Mechanical Tubing
ASTM A513 tuaj yeem yog carbon hlau lossis hlau alloy.
Qhov Loj
Kev tsim khoom
ASTM A500 Cov Txheej Txheem Ua Haujlwm
Tubing yuav tsum tau ua los ntawm aseamless los yog vuam txheej txheem.
Welded tubing yuav tsum tau ua los ntawm cov hlau tiaj tus los ntawm cov txheej txheem hluav taws xob-tiv taus-welding (ERW).
A500 feem ntau yog ua los ntawm cov hlau hauv lub xeev kub dov, ces txias-tsim thiab welded.
Lus Cim: Flat-rolled yog hais txog cov txheej txheem hlau ua haujlwm uas feem ntau siv rau cov hlau thiab lwm yam khoom siv hlau.Nyob rau hauv cov txheej txheem no, cov hlau pib nyob rau hauv nws cov thawj tej daim ntawv (xws li ingot) thiab yog flattened rau hauv nplooj ntawv los yog coils los ntawm ib tug kub los yog txias dov txheej txheem.
ASTM A513 Kev Tsim Khoom Txheej Txheem
Cov raj yuav tsum tau ua los ntawm cov txheej txheem hluav taws xob-tiv taus-welded thiab yuav tsum tau ua los ntawm kub-los yog txias-dov hlau raws li tau teev tseg.
Kev kho cua sov
ASTM A500 Kev kho cua sov
Cov raj hauv ASTM A500 tus qauv tsis tas yuav tsum tau kho cua sov.Qhov no yog vim ASTM A500 yog npaj rau kev siv cov qauv siv, qhov tseem ceeb ntawm cov qauv tsim muaj zog thiab toughness.Cov raj no feem ntau yog tsim los ntawm kev sib sau txias thiab tom qab vuam, siv cov khoom siv carbon steel uas twb muaj zog thiab tawv.
Txawm li cas los xij, hauv qee qhov tshwj xeeb, txhawm rau ua tiav cov khoom siv kho tshuab lossis ua kom tau raws li cov kev xav tau tshwj xeeb, cov raj thiab cov kav dej ntawm ASTM A500 tuaj yeem raug rau kev kho cua sov los yog kev ntxhov siab, tshwj xeeb yog qhov kev ntxhov siab seem raug tshem tawm tom qab vuam.
ASTM A513 Kev kho cua sov
ASTM A513 tus qauv muaj ntau hom tubing, qee qhov yuav raug kho kom sov kom ua tau raws li qhov xav tau ntawm txhua yam khoom.
NA(Tsis Annealed) - Tsis annealed;hais txog steel tubing uas tsis tau kho cua sov nyob rau hauv lub welded los yog kos mob, piv txwv li, nws yog sab laug nyob rau hauv nws qub mob tom qab welding los yog kos duab.Qhov kev kho mob no yog siv rau cov ntawv thov uas tsis muaj kev hloov pauv hauv cov khoom siv hluav taws xob yuav tsum tau ua los ntawm kev kho cua sov.
SRA(Stress Relieved Annealed) - Stress Relieved Annealing;Qhov kev kho cua sov no yog ua los ntawm qhov kub thiab txias hauv qab qhov ntsuas kub tseem ceeb ntawm cov khoom siv, nrog lub hom phiaj tseem ceeb ntawm kev tshem tawm cov kev ntxhov siab sab hauv tsim thaum lub sij hawm ua cov raj, yog li txhim kho qhov ruaj khov ntawm cov khoom thiab tiv thaiv deformation tom qab ua tiav.Kev ntxhov siab-relieving annealing feem ntau yog siv rau hauv machining ntawm precision qhov chaw los xyuas kom meej qhov ntev thiab cov duab raug.
N(Normalized lossis Normalized Annealed) - Normalized lossis normalized annealing;Kev kho cua sov ntawm qhov kub siab tshaj qhov ntsuas kub tseem ceeb ntawm cov khoom siv los ntawm qhov loj ntawm cov hlau tuaj yeem ua kom zoo dua qub thiab nws cov khoom siv dag zog thiab kev ua kom zoo dua qub.Normalizing yog ib qho kev kho cua sov uas siv los txhim kho cov khoom siv ntawm cov khoom siv los ua kom nws haum rau kev ua haujlwm siab dua.
Chemical Composition thiab Mechanical Properties
ASTM A500 tubing yog tsim los rau cov qauv tsim thiab muaj cov khoom siv tshwj xeeb (lub zog tensile, yield zog, elongation) thiab cov khoom siv tshuaj.
Nws yog lub npe hu rau nws zoo weldability thiab ductility thiab yuav siv tau nyob rau hauv cov qauv uas yuav tsum tau siab zog-rau-hnyav piv.
Muaj ntau ntau hom ASTM A513 tubing, txhua tus muaj nws tus kheej txhua yam thiab tshuaj lom neeg rau kev siv tshwj xeeb.
Piv txwv li, Hom 5 tubing yog lub tes tsho kos (DOM) cov khoom lag luam nrog nruj dua, kev ua kom zoo dua qub, thiab cov khoom siv zoo sib xws.
Cov cheeb tsam tseem ceeb ntawm daim ntawv thov
ASTM A500 feem ntau yog siv rau hauv cov khoom siv xws li cov tsev, txuas hniav, thiab cov khoom txhawb nqa.Nws yog siv nyob rau hauv qhov yuav tsum tau muaj zog thiab ruaj khov.
ASTM A513, ntawm qhov tod tes, yog siv rau hauv cov ntawv thov uas yuav tsum tau muaj kev ua siab ntev thiab kev ua tiav.Cov kev siv feem ntau suav nrog cov khoom siv tsheb thiab cov khoom siv tshuab uas yuav tsum tau ua kom haum ua ke nrog qhov tseeb heev.
Nqe
Cov khoom lag luam ASTM A500 feem ntau tsis tshua kim vim qhov tsis tshua muaj kev nruj me ntsis qhov tseeb ntawm cov txheej txheem tsim khoom.
ASTM A513, tshwj xeeb tshaj yog hom 5 (DOM), tuaj yeem kim dua vim tias yuav tsum tau siv lub tshuab ua kom zoo dua qub thiab qhov chaw tiav.
Yog li ntawd, kev xaiv ntawm ob hom steel yeeb nkab yuav tsum yog raws li cov kev xav tau tshwj xeeb ntawm qhov project.
Yog tias qhov project yuav tsum muaj lub zog thiab ua haujlwm ntev, ASTM A500 yog qhov kev xaiv tsim nyog dua.Txawm li cas los xij, rau cov ntawv thov uas xav tau siab precision thiab zoo heev saum npoo, ASTM A513 tej zaum yuav nyiam.
