Ob Qhov Kev Qhia Tshwj Xeeb Sau rau Ob Txoj Haujlwm sib txawv
ASTM A500 yog cov lus qhia tshwj xeeb rau txias tsim welded thiab seamless carbon steel structural tubing nyob rau hauv round, square thiab rectangular duab. Nws lav qhov tsawg kawg nkaus lub zog thiab tensile lub zog, thiab nws muaj nyob rau hauv thiaj li hais tias cov engineers muaj peev xwm tsim load- bearing thav duab, kab, braces thiab tshuab bases tawm tsam cov khoom siv kho tshuab luam tawm. ASTM A513 yog cov lus qhia tshwj xeeb rau hluav taws xob tiv thaiv welded carbon thiab alloy steel mechanical tubing, tsim los ntawm hom raws li lub raj ua thiab ua tiav. Nws yog ib qhov loj thiab zoo specification es tsis yog ib tug qauv tsim specification.
Ib lo lus nug tseem ceeb tshaj plaws thaum xaiv ntawm lawv yog qhov no: lub raj puas yuav suav nrog cov qauv thauj khoom, lossis nws puas yuav tsum tau tshuab, tsim, khoov lossis siv los ua cov khoom siv kho tshuab qhov twg qhov tseeb qhov loj dua qhov muaj peev xwm lav tau?
Cov khoom siv thiab lub zog yuav tsum muaj

Hom A513 Tubing
A513 tau teeb tsa kom tus neeg yuav khoom tuaj yeem sau npe rau kev tsim khoom thiab ua tiav txoj kev xav tau. Hom 1 yog round tubing ua los ntawm hluav taws xob kuj vuam thiab muab raws li welded nrog lub flash tshem tawm. Hom 1a yog tib yam khoom tiav rau ib qho kev qhia hauv txoj kab uas hla thiab sab nraud txoj kab uas hla. Hom 2 yog puag ncig tubing uas tau kos hla lub mandrel, feem ntau hu ua DOM tubing, muab kev tiv thaiv nruj dua thiab qhov chaw zoo dua rau sab hauv thiab sab nraud. Hom 5 yog square tubing thiab Hom 6 yog lub raj raj uas tsim los ntawm tib txoj kev welded thiab qhov loj me. Vim hais tias cov specification yog hais txog yuav ua li cas lub raj yog tsim, cov neeg kho tshuab zog nyob ntawm seb cov hlau xaiv thiab yuav tsum tau muab cais nyob rau hauv qhov kev txiav txim.
Corner Radius, Tolerance thiab Finish
A500 square thiab rectangular seem yog txhais nrog sab nraud kaum radii uas nce nrog phab ntsa thickness, thiab cov specification kuj teev tawm qhov tso cai variation nyob rau hauv sab nraud qhov ntev, squareness ntawm sab thiab ncaj. A513 square tubing feem ntau yog tsim nrog lub kaum sab xis me me sab nraud thiab lub ntsej muag nruj dua, uas yog qhov tseem ceeb thaum lub raj yuav tsum haum rau hauv lub welded los ua ke los yog machined rau sab nraud txoj kab uas hla. Cov ntsej muag zoo nkauj kuj txawv: A513 feem ntau yog muab nrog lub ntsej muag zoo nkauj, ci ntsa iab uas xav pom lossis pleev xim ncaj qha, thaum A500 ntu tau muab rau hauv qhov ua tau zoo li - tsim cov xwm txheej zoo li qub rau kev ua haujlwm.
Yuav xaiv li cas
Qhia meej A500 nrog qib npe npe thaum lub raj yog ib feem ntawm cov qauv tsim, thaum kos duab quotes lub zog tawm los, lossis thaum qhov project yog tswj hwm los ntawm cov qauv txheej txheem.
Qhia meej A513 thaum lub raj yuav raug machined, khoov, xuas nrig ntaus los yog sib sau ua ke rau hauv cov khoom uas qhov sib xws thiab qhov chaw tiav tswj qhov haum, thiab hais txog hom thiab cov khoom siv kho tshuab uas yuav tsum tau ua ntawm kev txiav txim.
Tsis txhob hloov A513 rau A500 hauv daim ntawv thov kev tsim tshwj tsis yog tus neeg muag khoom tuaj yeem lees paub qhov tsawg kawg nkaus qhov xav tau thiab lub zog tensile, vim A513 tsis lav cov nqi ntawd.
Qhov twg xav tau ob qho tib si lub zog thiab nruj, xaj A500 rau qib uas xav tau thiab ntxiv qhov yuav tsum tau muaj raws li cov kev xav tau ntxiv, lossis xaiv DOM cov raj siv tshuab thiab lees paub nws cov khoom sib cais.
FAQ
Q: Puas yog A500 square tubing muaj zog dua A513 tubing?
A500 lav qhov tsawg kawg nkaus tawm los thiab lub zog tensile rau qib npe, yog li nws yog qib uas tus qauv tsim nyob ntawm. A513 tsis muaj qhov yuav tsum tau muaj zog tsawg kawg nkaus hauv qhov tshwj xeeb, yog li lub raj A513 yuav muaj zog dua lossis tsis muaj zog nyob ntawm cov hlau siv.
Q: A500 thiab A513 raj puas tuaj yeem welded tib txoj kev?
Ob leeg yog cov tsis tshua muaj carbon steels thiab tau yooj yim welded los ntawm shielded hlau arc, roj hlau arc thiab kuj welding. Rau A500 cov txheej txheem vuam yuav tsum hwm cov qib uas tau siv, txij li Qib C muaj qhov siab tshaj plaws ntawm cov khoom muaj zog thiab cov pa roj carbon ntau dua.
Q: DOM tubing txhais li cas?
DOM sawv cev rau kos hla mandrel, uas yog A513 Hom 2 txheej txheem. Lub welded raj yog kos los ntawm ib tug mandrel thiab los ntawm ib tug tuag kom lub sab hauv thiab sab nrauv nto thiab cov phab ntsa kam rau ua kom muaj kev txwv ntau dua li -welded tubing.
Q: Qhov kev qhia tshwj xeeb twg muaj qhov nruj dua?
A513 muaj qhov nruj dua, tshwj xeeb tshaj yog nyob rau hauv hom DOM thiab hauv Hom 1a qhov chaw sab hauv tau teev tseg. A500 kam rau ua yog sau nyob ib ncig ntawm cov khoom seem es tsis yog precision haum.
Q: Puas yog ob qho kev qhia tshwj xeeb npog cov kab plaub hau?
Yog lawm. A500 npog puag ncig, square thiab duab plaub ntu, thiab A513 npog square tubing li Hom 5 thiab cov raj duab plaub raws li Hom 6.
Q: Puas yog A500 muaj nyob rau hauv qhov kub dov?
A500 cov khoom yog txias tsim, thiab nws yog feem ntau nkag nrog cov weld cheeb tsam normalized los yog tag nrho cov seem kev ntxhov siab relieved kom rov zoo uniformity ntawm cov khoom raws li ntev.
