ASTM A500 yog ib qho kev qhia tshwj xeeb rau cov khoom txias-tsim welded thiab seamless carbon steel structural tubing nyob rau hauv round, square, thiab rectangular duab. Qhov no hollow seem yog dav siv nyob rau hauv kev tsim kho, industrial, thiab engineering daim ntaub ntawv vim nws zoo heev lub cev yam ntxwv.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm ASTM A500 yog nws lub zog tensile siab thiab lub zog tawm los. Qhov no ua rau nws cov khoom siv ruaj khov heev, tuaj yeem tiv taus qhov hnyav thiab kev ntxhov siab. Tsis tas li ntawd, nws txoj kev tsim seamless txhais tau hais tias nws tsis tshua muaj kev tawg thiab corrosion, ua rau nws muaj kev ntseeg siab rau kev siv mus sij hawm ntev. Tsis tas li ntawd, cov hlau no kuj yooj yim rau vuam, txiav, thiab khoov, ua rau nws yooj yim rau cov duab thiab kho raws li. raws li qhov yuav tsum tau ua ntawm ib qhov project tshwj xeeb. Nws kuj tseem pheej yig, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov neeg siv nyiaj txiag thiab cov neeg cog lus.
Lwm qhov txiaj ntsig tseem ceeb ntawm ASTM A500 yog nws cov khoom siv ntau yam. Nws qhov ntau ntawm cov duab thiab qhov ntau thiab tsawg txhais tau hais tias nws tuaj yeem siv rau ntau yam kev siv, los ntawm lub tsev kab thiab kab teeb mus rau guardrails thiab handrails. Nws kuj tseem muaj nyob rau hauv ob qho tib si lub teeb yuag thiab hnyav-lub luag haujlwm xaiv, ua rau nws haum rau ntau yam ntawm qhov hnyav-kev coj tus kheej thiab tsis hnyav-kev coj tus kheej.
Muaj ob peb qib ntawm ASTM A500 steel hollow seem muaj nyob hauv khw. Cov qib feem ntau yog Qib A, Qib B, thiab Qib C.
Qib A yog qib siv dav tshaj plaws thiab tsim nyog rau feem ntau cov qauv siv. Nws muaj qhov tsawg kawg nkaus lub zog ntawm 39 ksi (270 MPa) thiab lub zog tensile yam tsawg kawg nkaus ntawm 45 ksi (310 MPa).
Qib B muaj lub zog me ntsis siab dua Qib A, nrog qhov tsawg kawg nkaus lub zog ntawm 46 ksi (315 MPa) thiab lub zog tensile yam tsawg kawg nkaus ntawm 58 ksi (400 MPa). Nws yog feem ntau siv nyob rau hauv cov ntaub ntawv uas muaj zog dua thiab toughness yuav tsum tau.
Qib C yog qib uas muaj zog tshaj plaws, nrog qhov tsawg kawg nkaus tawm lub zog ntawm 50 ksi (345 MPa) thiab lub zog tensile yam tsawg kawg nkaus ntawm 62 ksi (425 MPa). Nws yog feem ntau siv rau hauv cov ntawv thov uas yuav tsum muaj zog dua thiab lub neej ntev dua.
Zuag qhia tag nrho, ASTM A500 steel hollow seem yog ib qho kev xaiv zoo thiab raug nqi rau ntau yam kev siv cov qauv, los ntawm cov tsev thiab txuas hniav mus rau laj kab thiab cov qauv qauv.
