Qib C Cov Tube yog dab tsi
ASTM A500 yog tus qauv specification rau txias- ua welded thiab seamless carbon steel structural tubing, ua nyob rau hauv round, square thiab rectangular duab. Qib C nyob ze rau saum lub zog ntau yam uas tau teev tseg los ntawm cov lus qhia tshwj xeeb: rau cov square thiab cov duab plaub nws tau muab lub zog qis kawg nkaus ntawm 50 ksi, kwv yees li 345 MPa, thiab lub zog tensile yam tsawg kawg nkaus ntawm 62 ksi, kwv yees li 427 MPa, uas yog cov txiaj ntsig tau txais los ntawm kev tsim qauv tsim.
Cov tubing yog tsim los ntawm txias txoj kev steel sawb mus rau hauv ib tug hollow seem thiab welding lub longitudinal seam, los yog ua ib tug seamless hollow. Cold forming tsa lub zog tawm los ntawm cov ces kaum thiab muab cov seem kom raug, rov ua dua qhov ntev, thaum lub welded seam khiav tag nrho ntev ntawm tus tswv cuab thiab feem ntau yog nyob rau hauv raws li -welded mob.
Properties thiab Specification Requirements
| Yam khoom | Yuav tsum tau kawm qib C |
|---|---|
| Yam tsawg kawg nkaus yield zog | 345 MPa, kwv yees li 50 ksi, rau cov square thiab duab plaub |
| Tsawg kawg tensile zog | 427 MPa, hais txog 62 ksi, rau cov square thiab square |

Cov kev qhia tshwj xeeb tsis tas yuav muaj kev cuam tshuam rau hauv qib hauv paus, yog li qhov project uas xav tau qhov tsis zoo rau kev pabcuam kub yuav tsum hu rau nws raws li qhov yuav tsum tau ua ntxiv. Mechanical qhov tseem ceeb kuj txawv ntawm cov seem puag ncig thiab zoo li tus seem, yog li qhov kev xaiv qib ib leeg tsis kho lub zog: hom ntu yuav tsum tau teev nrog nws.
Qhov twg Qib C Tube siv
Kab, kab teeb, trusses thiab bracing nyob rau hauv kev lag luam, industrial thiab institutional vaj tse, nrog rau warehouses, logistics centre thiab tshav dav hlau qauv.
Choj cov ntsiab lus xws li cov neeg taug kev choj trusses, txoj kev kos npe txhawb nqa thiab gantry thav ntawv.
Ncej, booms thiab kev txhawb nqa rau kev ua liaj ua teb, mining, kev tsim kho thiab cov ntaub ntawv tuav machinery.
Tsheb thauj mus los infrastructure nrog rau guardrails, teeb pom kev zoo kab thiab tsheb teeb liab qauv.
Architecturally nthuav tawm cov qauv steelwork xws li canopies, atria, staircases thiab facade framing, qhov chaw huv si thiab cov seem seem yog ib feem ntawm lub hom phiaj tsim.
Yog vim li cas qib tau siv dav hauv cov ntawv thov no yog lub zog rau qhov hnyav piv ntawm qhov hollow seem. Ib tug square lossis rectangular hollow member resists dabtsi yog khoov ntawm ob lub ntsiab axes, yog li ib tug sib zog seem yuav nqa tau tib lub load raws li ib tug hnyav qhib profile, uas txo cov tuag load ntawm cov qauv thiab cov load nqa mus rau hauv lub hauv paus.
Tsim, Fabrication thiab Corrosion Protection
Tsim cov khoom siv los ntawm kev txo cov phab ntsa thickness ntawm 0.93 lub sij hawm nominal, thiab account rau lub kaum sab xis ntawm qhov txias -them seem.
Vuam ua raws li cov txheej txheem vuam txheej txheem siv rau qhov project, nrog cov txheej txheem tsim nyog rau qib thiab thickness ntau tau koom nrog.
Txias dabtsi yog khoov yog cov tswv yim ntawm nruab nrab radii; thaj tsam tsim yuav tsum tau kuaj xyuas cov phab ntsa thinning thiab rau lub zos distortion, tshwj xeeb tshaj yog nyob rau hauv cov phab ntsa hnyav.
Txiav qhov xaus thiab qhov chaw vuam yuav tsum tau hnav ua ntej galvanizing los yog pleev xim, thiab lub qhov cua thiab qhov dej yog xav tau nyob rau hauv cov tswv cuab kaw uas yuav kub dip galvanized.
Rau kev nthuav dav architectural ua hauj lwm, qhia kom meej qhov nto tiav thiab cov txheej txheem tiv thaiv ua ntej, vim hais tias raws li -muab nto qhov chaw sib txawv ntawm mills.
Kev soj ntsuam thiab xaj cov ntsiab lus
Txheeb xyuas cov qib, seem duab thiab qhov loj me, cov phab ntsa nominal thickness thiab qhov ntev tiv thaiv qhov kev txiav txim yuav thiab daim ntawv pov thawj zeb.
Tshawb xyuas qhov nro thiab flattening cov qhabnias thiab cov tshuaj ntsuam xyuas tau sau tseg rau ntawm daim ntawv pov thawj.
Ntsuas phab ntsa tuab ntawm ob peb lub ntsiab lus nyob ib ncig ntawm ntu, thiab xyuas qhov ntev ntawm sab nraud, kaum lub vojvoog, qhov ncaj thiab twist tiv thaiv cov rooj sib haum xeeb ntawm cov lus qhia.
Paub meej seb puas welded los yog seamless tubing tau muab nkag qhov twg tus tsim nyob ntawm nws.
Khaws tubing kom huv si hauv av thiab tiv thaiv nws los ntawm cov dej sawv ntsug kom tsis txhob muaj corrosion ua ntej fabrication.
FAQ
Q: ASTM A500 Qib C yog dab tsi?
Nws yog qib siab zog ntawm qhov txias txias- tsim cov qauv tubing specification, nrog rau qhov tsawg kawg nkaus yield zog ntawm 50 ksi, txog 345 MPa, thiab qhov tsawg kawg nkaus tensile lub zog ntawm 62 ksi, txog 427 MPa, rau square thiab rectangular seem.
Q: Qib C piv nrog Qib B li cas?
Qib C yog qib siab zog. Qib B tau muab lub zog qis qis dua rau tib hom ntu, yog li Qib C nqa ntau dua rau tib seem loj.
Q: Puas yog Qib C tubing welded lossis seamless?
Cov lus qhia tshwj xeeb npog ob qho tib si txias- ua welded thiab seamless tubing, yog li daim ntawv yuav tsum tau muab teev thaum xaj.
Q: Vim li cas lub phab ntsa txo qis siv hauv kev tsim?
Vim tias qhov kev qhia tshwj xeeb tso cai rau phab ntsa yog 10% hauv qab nominal, cov qauv tsim cov lej yuav tsum tau suav cov seem raws li tus qauv tsim thickness ntawm 0.93 npaug ntawm nominal phab ntsa.
Q: Puas yog Qib C raj tau lees paub qhov cuam tshuam toughness?
Tsis yog. Kev ntsuam xyuas qhov cuam tshuam tsis yog ib feem ntawm lub hauv paus specification thiab yuav tsum tau txiav txim raws li qhov yuav tsum tau ua ntxiv thaum xav tau kev sib tw toughness.
Q: Dab tsi ntawm qhov chaw tiv thaiv lub raj xav tau?
Cov khoom yog muab liab qab, yog li kev tiv thaiv nyob ntawm daim ntawv thov: painting, galvanizing los yog lwm txheej txheej yog xaiv raws li qhov raug thiab lub neej ntawm cov qauv.
