Kev kam rau siab ntau lawm ntawm ASTM A500
Cov kws tshaj lij feem ntau xav paub yog vim li cas thiaj li muaj kev xaiv tsawg dua rau A53 cov kav dej piv rau A500 kav dej.
A53 cov kav dej yog tsim los siv cov yeeb nkab nominal hauv nti, nrog rau ib qho ntawm peb lub phab ntsa thicknesses. Lawv loj npaum li no kom haum rau A53 cov kav dej 'lub hom phiaj xav tau- thauj cov pa cua, cua, lossis dej- yuav tsum muaj kev sib raug zoo nrog cov qauv fittings thiab li qub.
Cov kev cai zoo li no tsis siv rau A500 cov raj, tso cai rau kev tsim kom meej dua thiab siv tau zoo. A500 rounds suav nrog sab nraud txoj kab uas hla thiab phab ntsa thickness nyob rau hauv nti, ntsuas rau peb qhov chaw decimal. Piv txwv li, thaum siv A500 puag ncig rau lub tsev kem, HSS8.625 × 0.322 tuaj yeem teev nrog lub cheeb sab nraud (OD) kam rau ua ntawm +/-0.75% thiab phab ntsa kam rau ua ntawm +/-10%. Nyob rau hauv sib piv, qhov sib npaug A53, ib tug 8-nti txheem yeeb nkab, muaj ib tug OD kam rau ua ntawm +/-1% thiab ib phab ntsa kam rau ua ntawm -12.5%. Qhov no qhia tau hais tias A500 rounds muaj superior OD thiab phab ntsa kam rau ua.
Xaiv A500 rounds rau koj cov qauv tubing xav tau, tau txais txiaj ntsig los ntawm lawv cov kev kam rau siab zoo thiab qhov yooj yim uas lawv muaj nyob rau hauv kev ua tau raws li cov kev cai tshwj xeeb rau phab ntsa tuab thiab sab nraud.

A500 Sab nraum Dimensional Tolerances rau Square Tubing
1. Sab nraud Dimensions (dav thiab qhov siab):
Sab nraud qhov ntev (dav thiab qhov siab) ntawm square tubing feem ntau raug rau cov hauv qab no kam rau ua:
Dav thiab qhov siab kam rau ua: +/- 0.020" (0.5 hli)
2. Squareness ntawm Sab:
Qhov sib txawv ntawm kab pheeb ces kaum ntawm tib tus ntoo khaub lig-section yuav tsum tsis pub tshaj 1% ntawm nominal qhov ntev.
A500 Sab nraum Dimensional Tolerances rau Rectangular Tubing
1. Sab nraud Dimensions (dav thiab qhov siab):
Sab nraud qhov ntev (dav thiab qhov siab) ntawm lub raj raj yog feem ntau raug rau cov hauv qab no kam rau ua:
Dav Tolerance: +/- 0.020" (0.5 hli)
Qhov siab kam rau ua: +/- 0.010" (0.25 hli)
2. Squareness ntawm Sab:
Qhov sib txawv ntawm kab pheeb ces kaum ntawm tib tus ntoo khaub lig-section yuav tsum tsis pub tshaj 1% ntawm nominal qhov ntev.
Yog tias koj muaj kev zam tshwj xeeb rau koj qhov project, nws raug nquahu kom sib txuas lus cov cai no kom meej nrog UNIACERO tus kws ua haujlwm.
A500 Carbon Steel Twist Tolerances rau Square & Rectangular Structural Tubing
ASTM A500 tsis tshwj xeeb muab kev sib tw rau kev sib tw rau cov square thiab duab plaub. Txawm li cas los xij, qhov yuav tsum tau ua kom ntev ntev tuaj yeem muab tau los ntawm cov qauv kev lag luam dav dav thiab cov kev coj ua siv tau rau cov khoom siv hlau.
Twist feem ntau txhais tau tias yog kev sib hloov ntawm ib qho kawg ntawm cov tubing txheeb ze rau lwm qhov kawg raws li qhov ntev axis. Nws yog ntsuas nyob rau hauv degrees rau ib chav tsev ntev (piv txwv li, degrees ib ko taw).
Qhov siab tshaj plaws Twist: Qhov siab tshaj plaws twist tso cai rau cov square thiab duab plaub feem ntau teev raws li tus lej ntawm cov degrees ntawm qhov ntev (piv txwv li, ib ko taw).
Kev lag luam Standards: Cov qauv kev lag luam xws li ASTM A6 / A6M, uas suav nrog cov kev xav tau dav dav rau cov khoom siv hlau yob, daim hlau, cov duab, thiab cov ntawv piling, tuaj yeem muab kev taw qhia txog kev tso cai rau kev sib tw tsis ncaj rau cov qauv tubing.
Kev xyaum ua: Nyob rau hauv kev xyaum, twist tolerances rau square thiab rectangular tubing yuav txawv nyob ntawm seb tus txheej txheem tsim, qhov loj me, thiab cov neeg siv khoom tshwj xeeb.
Feem ntau, twist tolerances yog teev raws li cov neeg siv khoom kos duab, qhov project specifications, lossis pom zoo- raws li cov qauv ntawm cov chaw tsim khoom thiab cov neeg siv khoom.
