ASTM A500 thiab ASTM A501ob qho tib si hais txog cov kev cai cuam tshuam nrog kev tsim cov yeeb nkab carbon steel.
Txawm hais tias muaj qhov zoo sib xws hauv qee qhov, lawv kuj muaj lawv tus kheej cov yam ntxwv thiab kev siv.
Tom ntej no peb yuav saib qhov sib txawv tseem ceeb ntawm ASTM A500 thiab ASTM A501 thiab lawv siv li cas hauv ntau daim ntawv thov sib txawv.
Cov Txheej Txheem Tsim Khoom
ASTM A500 Cov Txheej Txheem Tsim Khoom
ASTM A50 yeeb nkab yuav tsum tau tsim los ntawm cov txheej txheem seamless lossis welded.
Cov kav dej welded yuav tsum ua los ntawm cov hlau tiaj tiaj los ntawm cov txheej txheem hluav taws xob-resistant-welding (ERW).
ASTM A501 Cov Txheej Txheem Tsim Khoom
Cov kav dej yuav tsum tau tsim los ntawm ib qho ntawm cov txheej txheem hauv qab no: seamless, lub cub tawg butt welding (txuas ntxiv welding); tsis kam welding lossis submerged arc welding.
Tom qab ntawd nws yuav tsum tau rov ua kom sov dua thoob plaws tag nrho cov seem thiab thermoformed los ntawm kev txo qis lossis tsim cov txheej txheem, lossis ob qho tib si.
Qhov kev tsim cov duab kawg yuav tsum ua los ntawm cov txheej txheem kub.
Cov Txheej Txheem Tsim Khoom Sib Txawv
Ob qho qauv no tso cai rau kev siv cov txheej txheem tsim cov yeeb nkab seamless;
Yog tias siv cov txheej txheem vuam rau kev tsim khoom, ASTM A500 siv hluav taws xob-tsis kam-welded (ERW), thaum ASTM A501 tso cai rau ntau yam kev vuam, suav nrog hluav taws xob-tsis kam-welded (ERW), submerged arc welding (SAW), thiab lwm yam.
Txawm li cas los xij, ASTM A501 xav kom cov yeeb nkab raug kho cua sov, uas pab txhim kho qhov sib xws thiab cov khoom siv kho tshuab ntawm cov khoom. Lub hom phiaj ntawm thermoforming yog los txhim kho cov khoom siv los ntawm kev kho cua sov rau cov yeeb nkab ua ntej nws cov duab tiav.
ASTM A500 tsis muaj cov kev cai ntxaws ntxaws no.
Kev faib tawm ntawm cov qib
Qhov Loj Siv Tau
Cov Cheebtsam Tshuaj
Thaum muab ua ke, muaj qee qhov sib txawv ntawm cov tshuaj lom neeg ntawm cov kav hlau carbon uas tau teev tseg hauv ob tus qauv, ASTM A500 thiab ASTM A501.
Hauv ASTM A500, Qib B thiab Qib D muaj cov kev cai sib xyaw ua ke zoo ib yam, thaum Qib C muaj cov pa roj carbon tsawg dua piv rau B thiab D. Hauv ASTM A501, cov tshuaj lom neeg ntawm Qib A zoo ib yam li Qib B, thaum Qib C muaj cov pa roj carbon tsawg dua piv rau Qib B.
Hauv ASTM A501, cov tshuaj lom neeg ntawm Qib A zoo ib yam li Qib B thiab D ntawm A500, tab sis hauv Qib B thiab C cov ntsiab lus carbon raug txo qis, cov ntsiab lus manganese raug nce me ntsis, thiab cov ntsiab lus phosphorus thiab sulfur qis dua li Qib A.
Cov ntsiab lus tooj liab tseem yog qhov yuav tsum tau ua tsawg kawg nkaus thoob plaws txhua qib.
Cov kev cai sib txawv ntawm cov tshuaj lom neeg sib txawv qhia txog cov kev xav tau tshwj xeeb ntawm ob tus qauv rau cov txheej txheem tsim khoom thiab cov ntawv thov sib txawv, kom ntseeg tau tias cov khoom siv ua tau raws li cov qauv kev ua tau zoo rau ntau yam kev siv engineering thiab cov qauv.
Kev Ua Haujlwm Txog Tshuab
ASTM A500 Kev Ua Haujlwm Txog Kev Kho Tshuab
ASTM A501 Kev Ua Haujlwm Txog Kev Kho Tshuab
Cov Khoom Siv Kho Tshuab Sib Txawv
Cov ntaub ntawv hauv A501 feem ntau muab cov qib siab dua ntawm lub zog vim yog lub zog ntxiv ntawm cov hlau los ntawm cov txheej txheem kub.
Cov Haujlwm Sim
Cov kev cai sib txawv rau cov khoom sim hauv ob tus qauv qhia txog cov txheej txheem tsim khoom thiab kev siv ntawm ob lub raj sib txawv no.
Tus qauv ASTM A500 xav tau Kev Tshawb Fawb Thermal, Kev Tshawb Fawb Khoom, thiab Cov Khoom Siv Kho Tshuab ntxiv rau Kev Ntsuas Flattening, Kev Ntsuas Flaring, thiab Wedge Crush Test kom ntseeg tau tias cov txheej txheem tsim txias tsis cuam tshuam tsis zoo rau cov khoom siv.
Tus qauv ASTM A501 hais txog cov txheej txheem thermoforming, thiab vim tias cov khoom thermoformed twb tau kho cua sov thaum lub sijhawm tsim khoom, cov kev sim no yuav raug suav hais tias tsis tsim nyog vim tias kev kho cua sov twb tau ua kom ntseeg tau tias cov khoom siv plasticity thiab toughness.
Cov Cheeb Tsam ntawm Daim Ntawv Thov
Txawm hais tias ob qho tib si ua lub luag haujlwm tseem ceeb, qhov tseem ceeb yuav txawv.
ASTM A500 tubing yog siv dav hauv kev tsim kho vaj tse, kev tsim khoom siv, cov thav tsheb, thiab cov khoom siv ua liaj ua teb vim nws cov khoom siv khoov txias thiab vuam zoo.
ASTM A501 tubing yog qhov tsim nyog dua rau kev tsim kho thiab cov qauv siv uas xav tau lub zog siab dua thiab kev tawv, xws li kev tsim kho choj thiab cov qauv txhawb nqa loj, vim nws cov tawv thiab lub zog zoo heev.
Ob qho qauv no muab cov lus qhia rau kev tsim cov yeeb nkab hlau carbon zoo, tab sis qhov kev xaiv zoo tshaj plaws nyob ntawm qhov yuav tsum tau ua thiab kev txwv ntawm ib qho project tshwj xeeb.
Yog tias ib lub tsev xav tau kev ua haujlwm zoo hauv qhov chaw kub qis, ASTM A501 yuav yog qhov zoo dua vim tias qhov kev ua kom muaj zog ntxiv los ntawm kev kub hnyiab ua rau muaj kev tiv thaiv zoo dua rau kev tawg yooj yim. Ntawm qhov tod tes, yog tias lub tsev yuav tsum tau tsim rau ib puag ncig sab hauv tsev, ces ASTM A500 yuav txaus, vim nws tuaj yeem muab lub zog thiab kev ua haujlwm tau raws li qhov xav tau, thaum pheej yig dua.
Cov cim npe: a500 vs a501, astm a500, astm a501, carbon steel, cov yeeb nkab qauv.
