Lub 100x100 square yeeb nkab nrog 4 hli phab ntsa thickness hnyav txog 12.06 kg ib 'meter' nyob rau hauv carbon steel. Qhov hnyav hloov pauv ncaj qha nrog phab ntsa tuab: 3 hli phab ntsa muab txog 9.09 kg ib meter, thiab phab ntsa 6 hli muab txog 17.74 kg ib meter. Txhawm rau kom tau txais tus nqi tseeb, siv tus ntoo khaub lig- ntu qauv hauv qab no siv cov phab ntsa tuab thiab cov khoom ntom ntom.
Qhov hnyav ntawm kev xam cov qauv
Qhov hnyav ntawm ib qho square hollow seem yog qhov ntim ntawm cov hlau nyob hauv phab ntsa multiplied los ntawm qhov ntom ntawm cov hlau. Rau ib square yeeb nkab nrog sab ntev S thiab phab ntsa thickness t, theoretical nyhav ib 'meter' yog xam raws li nram no:
W=(S squared minus (S minus 2t) squared) muab faib ua 7850 / 1000000, hauv kg ib meter, qhov S thiab t yog millimeters thiab 7850 yog qhov ceev ntawm carbon steel hauv kg ib cubic meter.
Rau 100x100 seem no yuav: W=(10000 rho (100 rho tawm 2t) squared) muab 0.00785 kg ib 'meter'. Lub sij hawm (100 rho tawm 2t) squared yog thaj tsam sab hauv, thiab rho tawm ntawm thaj tsam sab nraud tawm ntawm tus ntoo khaub lig- ntu ntu ntawm phab ntsa.
Ua piv txwv rau 100x100x4
Siv 100x100 square yeeb nkab nrog 4 hli phab ntsa. Qhov chaw sab nraud yog 100 x 100, lossis 10000 square millimeters. Sab hauv square yog 92 x 92, lossis 8464 square millimeters. Phab ntsa cheeb tsam yog 10000 rho tawm 8464, los yog 1536 square millimeters. Muab 0.00785 kg ib square millimeter ib 'meter' muab 12.06 kg ib 'meter'. Ib tug 6 meter ntev ntawm seem no hnyav txog 72.3 kg.
Daim ntawv hnyav rau 100x100 Square Pipe
| Phab ntsa Thickness mm | Theoretical Nyhav kg/m | Qhov hnyav ntawm 6 m kg |
|---|---|---|
| 2 | 6.15 | 36.9 |
| 3 | 9.09 | 54.5 |
| 4 | 12.06 | 72.3 |
| 5 | 14.91 | 89.5 |

| 8 | 23.29 | 139.7 |
| 10 | 28.67 | 172.0 |
Lub rooj yog xam rau carbon steel ntawm 7850 kg ib cubic meter. Stainless hlau seem hnyav li 1 feem pua ntau dua rau ib chav tsev ntim, thiab cov seem txhuas txog ib feem peb ntawm cov hlau hnyav rau tib qhov ntev.
Cov qauv rau Square Hollow Sections
Square yeeb nkab thiab raj yog tsim rau cov qauv sib txawv nyob ntawm kev ua lag luam thiab daim ntawv thov. ASTM A500 npog txias- tsim welded thiab seamless carbon steel structural tubing nyob rau hauv North America, nrog qib A, B, C thiab D. EN 10219 npog txias- tsim welded structural hollow seem nyob rau hauv cov teb chaws Europe, nrog rau qib xws li S235, S25.5 thiab S3 GB/T 6728 npog txias{10}}tsim welded hollow seem hauv Suav teb, nrog qib Q235 thiab Q345. Lub theoretical hnyav nyob rau hauv lub rooj yog lub hauv paus rau zeb pricing thiab logistics nyob rau hauv feem ntau cov khw, thiab qhov tseeb qhov hnyav kam rau ua yog feem ntau ntxiv los yog rho tawm 6 feem pua ntawm ib ntu.
Vim Li Cas Nyhav Teeb Meem Hauv Kev Xyaum
Qhov hnyav txiav txim siab tus nqi thauj khoom, lub peev xwm nqa khoom xav tau ntawm qhov chaw, thiab lub nra ntawm cov qauv txhawb nqa. Cov kws tsim qauv tsim qauv kuaj xyuas tus kheej- qhov hnyav ntawm cov kav dej square ua ntej suav cov khoom nyob, thiab cov neeg yuav khoom siv qhov ntsuas theoretical kom paub meej tias muaj pes tsawg daim uas haum rau hauv lub thawv. Rau lub thawv 20-ko taw, qhov ua tau zoo ntawm ib puag ncig 21 tonnes txwv qhov ntau ntawm 100x100x4 ntu rau kwv yees li 290 daim ntawm 6 meters txhua.
Feem ntau yuam kev hauv kev kwv yees qhov hnyav
Siv thaj chaw sab nraud tsis yog phab ntsa hla-section.
Tsis quav ntsej lub kaum sab xis, uas txo qhov hnyav me ntsis hauv qab qhov ntse - kaum kev xam.
Sib tov millimeter thiab meters hauv cov qauv.
Tsis nco qab tias galvanized lossis coated seem ntxiv me me ntxiv qhov hnyav rau txheej.
FAQ
Q: Ntau npaum li cas 100x100x4 square yeeb nkab hnyav ib 'meter'?
Txog 12.06 kg ib meter hauv carbon steel. Qhov ntev ntawm 6 'meter' hnyav li 72.3 kg.
Q: Puas yog qhov hnyav ntawm cov yeeb nkab square nyob ntawm qhov ntev?
Qhov hnyav yog proportional rau ntev. Tus nqi ib - meter yog tsau rau ib phab ntsa thickness, thiab tag nrho qhov hnyav yog tus nqi ib -meter tus nqi muab los ntawm qhov ntev.
Q: Dab tsi yog cov qauv rau square yeeb nkab hnyav?
W=(S squared minus (S minus 2t) squared) muab ntau los ntawm qhov ntom, qhov twg S yog sab ntev, t yog phab ntsa thickness thiab ceev yog 7850 kg ib cubic meter rau carbon steel. Qhov tshwm sim yog qhov hnyav ntawm ib chav tsev ntev nyob rau hauv tib chav tsev system.
Q: Ntau npaum li cas hnyav dua stainless hlau 100x100 square raj?
Stainless hlau ntom yog li ntawm 7930 kg ib cubic meter, kwv yees li 1 feem pua siab dua carbon steel, yog li qhov hnyav nce li ntawm 1 feem pua rau qhov zoo tib yam.
Q: Tus qauv twg npog 100x100 square yeeb nkab?
Cov qauv siv tau nyob ntawm kev ua lag luam. ASTM A500 muaj nyob rau hauv North America, EN 10219 hauv Europe thiab GB / T 6728 hauv Suav teb. Paub meej txog qib thiab tus qauv thaum xaj.
Q: Vim li cas qhov hnyav xa tawm txawv ntawm lub rooj?
Mill tolerances ntawm phab ntsa thickness thiab seem loj ua rau me me variations. Kev xa khoom hnyav yog ib txwm nyob ntawm qhov ntsuas theoretical lossis qhov hnyav, raws li pom zoo hauv daim ntawv cog lus yuav khoom.
