ASCE rail yog dab tsi?
IbASCE railyog lub teeb-rau- nruab nrab-lub luag haujlwm T-rail profile tsim raws li cov lus qhia los ntawm American Society of Civil Engineers (ASCE). Cov tsheb ciav hlau no tau siv dav hauv kev tsheb ciav hlau, kev lag luam, thiab kev siv crane, nrog rau qhov hnyav li ntawm 25 mus rau 85 phaus ib mev. Lawv qhov ntev yog tus qauv, feem ntau nrog qhov siab sib npaug ntawm lub hauv paus dav.
ASCE Rail Specifications:
ASCE Rails tau muab los ntawm GNEE RAIL hauv cov qauv kev tsheb nqaj hlau hauv qab no, cov ntaub ntawv no tau muab hauv mm thiab kg, yog tias koj xav tau lwm yam version hauv nti, xa lus tam sim no rau lwm lub version.

ASCE Rail Standards thiab Classification:
ASCE rails tau txhais los ntawm lawv qhov hnyav ntawm ib lub vaj, ib qho kev xaiv uas tseem tsis tau hloov pauv rau ntau dua ib puas xyoo. Tus txheej txheem npog cov ntu xws li 12 lb mus rau 100 lb ib yard, nrog tus lej qhia qhov hnyav nominal. Rau cov ntawv thov kev lag luam, cov seem feem ntau yogUAS 40, UAS 60, thiabTIAB SA 85. Txhua ntu muaj qhov tshwj xeeb asce 60 rail qhov ntev thaum piv rau nws cov sib dua lossis hnyav dua.
Lub asce 60 rail qhov ntev sawv cev rau ib lub xwmfab profile uas qhov siab sib npaug ntawm lub hauv paus dav - tus yam ntxwv uas yooj yim mounting rau ntawm qhov chaw tiaj tus. Cov ntu hnyav dua, xws liTIAB SA 85, muaj lub hauv paus dav uas tshaj qhov siab, muab ntau dua lateral stability rau loj crane loads. Cov ntu sib dua, xws liUAS 40, yog siv rau lub teeb heev hloov tsheb los yog ib ntus lem.
Hlau Khoom Qib rau ASCE Rail
ASCE rails (25–85 lb / yd) feem ntau yog tsim los ntawm cov qib carbon steel sib haum rau ASTM A1 cov qauv, feem ntau 700-qib (rau cov tsheb ciav hlau sib dua) thiab 900A / 1100-qib (rau hnyav dua rail). Cov khoom siv dav dav suav nrog Q235B, 55Q, thiab U71Mn rau ntau lub zog tensile, hnav tsis kam, thiab hardness hauv kev lag luam, crane, thiab kev siv tsheb ciav hlau.
- ASTM A1 (Carbon Steel Rail):Muaj feem xyuam rau lub teeb tsheb ciav hlau (xws li ASCE).
- ASTM A759 (High-Strength Rail Steel):Siv nyob rau hauv tej cheeb tsam export.
- National los yog enterprise qauv(xws li Tuam Tshoj Q235B / Q275, 55Q, thiab lwm yam)

ASCE 20-80 Steel Rails Classified los ntawm Daim Ntawv Thov
ASCE 20–80 steel rails, txhais los ntawm American Society of Civil Engineers (ASCE) cov qauv, yog tee rails cais los ntawm qhov hnyav ib yard (20 txog 80 lbs / yd) thiab siv feem ntau rau lub teeb- txoj haujlwm railway, mining lem, thiab industrial crane runways. Lawv tau muab faib ua lub teeb- hnyav (20–50 lb) rau mining/construction, thiab hnyav dua seem (60–80 lb) rau cranes thiab industrial logistics.
ASCE Rail Classification los ntawm Daim Ntawv Thov
- Lub Teeb Lub Luag Haujlwm & Kev Mining ib ntus (ASCE 20–40):Feem ntau siv rau kev lag luam me me, lub teeb nyiaj siv ua haujlwm cranes, kev thauj mus los hauv av, thiab kev tsim kho kev tsheb ciav hlau ib ntus.
- Medium Duty & Industrial (ASCE 50–60):Siv rau kev lag luam mining lem, tuav cov khoom, thiab sib dua crane runway daim ntaub ntawv.
- Heavy Duty Crane & Infrastructure (ASCE 75–80):Tshwj xeeb tsim los rau hnyav- lub luag haujlwm crane khiav, chaw nres nkoj logistics, nroj tsuag, thiab kev lag luam spur lem uas yuav tsum tau muaj zog dua thiab durability.
Cov lus nug nquag nug (FAQ)
1. ASCE sawv cev rau dab tsi hauv kev tsheb ciav hlau?
ASCE sawv cev rau American Society of Civil Engineers, uas yog thawj tus qauv ntawm cov kab tsheb ciav hlau no. ASCE rails yog txhais los ntawm lawv qhov hnyav hauv phaus ib mev, xws li asce 60 rail, uas hnyav 60 lb ib mev.
2. ASCE rails txawv ntawm AREMA rails li cas?
ASCE rails muaj lub tiaj tiaj hauv qab thiab yog tsim los rau kev txuas ncaj qha rau ntawm qhov chaw nruj xws li cov kab hlau los yog pob zeb. AREMA rails yog npaj rau ballasted mainline railway khiav thiab muaj ib tug dav puag nrog ib tug complex profile. Lub asce 60 rail qhov ntev yog square (qhov siab sib npaug ntawm lub hauv paus dav), whereas AREMA seem feem ntau muaj lub hauv paus dav dua qhov siab.
