Qhov sib txawv ntawm Astm A500 Yeeb Nkab thiab A53 Yeeb Nkab
ASTM A500 Yeeb Nkab thiab ASTM A53 Yeeb Nkab yog ob qho qauv sib txawv ntawm cov yeeb nkab steel, lawv sib txawv hauv cov khoom, siv thiab tsim qauv txheej txheem:
ASTM A500 YEEB NKAUJ:
Lub ATTM A500 tus qauv qhia txog qhov yuav tsum tau ua rau cov yeeb nkab txias thiab seamless carbon cov hlau txheem. Cov hlab no muaj feem ntau siv rau cov hom phiaj txheej xws li cov tuam tsev, txuas hniav thiab tshuab tshuab.
Cov hlab no muaj nyob rau hauv ntau yam ntawm cross-seem ntawm cov ntawv hla (piv txwv li, puag ncig, thiab lwm yam) thiab muaj nyob hauv cov qib sib txawv raws phab ntsa tuab thiab taub.
A500 hlab yog ua los ntawm tsuas yog cov hlau roj carbon thiab yog tsim los ntawm kev ua kom txias thiab haum rau welded thiab bolted qauv qauv.
ASTM A53 Yeeb:
Lub ASTM A53 qauv npog seamless thiab welded carbon steel yeeb nkab ntawm ferrod cov ntaub ntawv. Cov kav dej hlau no feem ntau yog siv rau cov ntawv thov txo qis xws li cov qauv kev txhawb nqa, chaw nyob thiab cov khoom siv tso hluav taws xob.
A53 yeeb nkab tau muab faib ua ntau pawg sib cais (hom A, B, thiab F) yog cov feem ntau siv vim tias lawv cov khoom siab dua thiab tawv.
Cov hom ntawm cov hlua feem ntau yog tsim cov cua sov lossis kev tawm tsam vuam thiab tuaj yeem siv rau dej thauj (xws li dej, roj, thiab lwm yam).
Txhawm rau muab cov ntsiab lus, A500 cov raj muaj feem ntau siv hauv kev tsim cov qauv thiab kev siv tshuab uas muaj zog ntau dua nyob rau hauv cov qauv dav dav thiab cov pa taws.
