ASTM A500 yog tus qauv qauv tsim los ntawm Astm International rau cold {1} Taug kev vab roj hmab thiab seamless carbon hlau tubing hauv round, square, thiab duab plaub. Ntawm nws ntau cov qib, qib qhab, qib B yog ib qho ntawm cov qhab nia feem ntau teev thiab siv cov qhab nia rau cov ntawv thov cov qauv.
Cov qib ntawm cov hlau no muaj npe rau nws tau zoo ua ke ntawm lub zog, ductility, thiab weldability. Nrog rau qhov tsawg kawg los lub zog ntawm 42,000 psi (290 MPA muaj zog ntawm 58,000 PSI (400 MPA), A500 {{9} qhov hnyav. Qhov no ua rau nws cov khoom siv zoo tshaj plaws rau kev tsim qauv kev ua haujlwm uas yuav tsum tau siv lub peev xwm ntau dhau los, ua rau ntau cov kev tsim muaj txiaj ntsig thiab kev lag luam.
A500 qib qib b tubing yog feem ntau siv nyob rau hauv kev tsim kho kev lag luam ua ib qho khoom siv tseem ceeb rau cov tswv cuab. Nws cov ntawv thov yog qhov dav thiab suav nrog cov kab hauv tsev, kab teeb, tracings, thiab kev tsim tawm hauv kev ua lag luam, kev lag luam. Tshaj li cov thav ntawv tsim, nws tseem muaj ntau yam siv nyob rau hauv txoj kev sib cav ntawm cov cim kev loj, cov kev pab txhawb nqa thiab ntau hom khoom muaj thiab cov tshuab ntim khoom thiab ntau yam khoom lag luam.
Lub tubing tuaj yeem tsim los ua seamless lossis welded. Cov txheej txheem tsim khoom ua rau lub huv huv, zoo nkauj dua piv rau cov qauv qauv zoo li kuv nyiam, uas feem ntau tsim nyog nyob rau hauv cov ntawv thov architectural. Nws cov lus qhia zoo sib xws thiab cov chaw du ntxiv tseem yooj yim yooj yim ua ntaub ntawv thiab cov txheej txheem ua tiav.
Hauv cov ntsiab lus, Astm A500 qib B Cov yeeb nkab steel yog yog qhov tseem ceeb thiab ntau yam khoom hauv cov qauv niaj hnub ua haujlwm. Nws cov cuab yeej txhim khu kev qha, raug nqi- ua tau zoo rau nws txoj haujlwm ua kev xaiv ua -}} kev ua haujlwm ntawm kev daws teeb meem.
