Qhov hnyav xam mis ntawm carbon steel tube / tubing:
Muaj ob lub ntsiab qhov hnyav ntawm cov qauv rau cov pa roj carbon steel, ib qho yog xam raws li lub cheeb sab nraud, phab ntsa thickness thiab ntev, thiab lwm yam yog xam raws li ntim ntim.
1. Muab xam raws li sab nraud txoj kab uas hla, phab ntsa thickness thiab ntev:
Qhov hnyav ntawm carbon steel tube (grams)=π × (sab nraud txoj kab uas hla-phab ntsa thickness) × phab ntsa thickness × ntev × ceev
Ntawm lawv, π≈3.1415926, thiab qhov ceev yog 7.85 g / cm³.
2. Kev xam raws li ntim ceev:
Qhov hnyav ntawm carbon steel tube (grams) {{{0}}} txheej txoj kab uas hla × sab nraud × ntev × ntim ceev × 0.02466
Ntawm lawv, qhov ceev ntau yog 7.85 g / cm³, thiab 0.02466 yog qhov hloov pauv chav tsev.
Vim qhov tso cai sib txawv ntawm cov hlau hauv cov txheej txheem tsim khoom, qhov ntsuas theoretical suav los ntawm cov qauv yog txawv me ntsis ntawm qhov hnyav tiag tiag, yog li nws tsuas yog siv los ua kev kwv yees. Qhov no yog ncaj qha ntsig txog qhov ntev qhov ntev, ntu ntu ntu thiab qhov siab ntev ntawm cov hlau.
Qhov hnyav ntawm cov hlau yog hais txog qhov hnyav tau los ntawm qhov hnyav (qhov hnyav) ntawm cov hlau, uas yog hu ua qhov hnyav tiag tiag.
Qhov tseeb qhov hnyav yog qhov tseeb dua li qhov ntsuas qhov ntsuas.
Piv txwv qhov hnyav ntawm carbon steel tube:
Piv txwv li, qhov hnyav ntawm lub raj carbon steel nrog ib txoj kab uas hla ntawm 60 hli, phab ntsa thickness ntawm 4 hli, thiab qhov ntev ntawm 3m yog xam raws li nram no:
1. Muab xam raws li sab nraud txoj kab uas hla, phab ntsa thickness thiab ntev:
Qhov hnyav ntawm carbon steel tube (grams)=π × (60-4) × 4 × 300 × 7.85 ≈ 223,149 grams, uas yog kwv yees li 223.15 kilograms.
2. Kev xam raws li ntim ceev:
Qhov hnyav ntawm carbon steel raj (grams) {{0}} × 60 × 300 × 7.85 × 0.02466 ≈ 223,149 grams, kwv yees li 223.15 kilograms.
Tej yam uas yuav tsum nco ntsoov thaum xam qhov hnyav ntawm carbon steel hlab:
1. Thaum xam, xyuam xim rau kev sib koom ua ke, xws li chav tsev ntawm qhov ntev yog 'meter', chav tsev ntawm qhov ceev yog g / cubic centimeter, thiab lwm yam.
2. Thaum ua kev suav, ua tib zoo saib xyuas qhov yuam kev. Piv txwv li, kev ntsuas qhov tseeb ntawm sab nraud thiab phab ntsa thickness yuav tsum siab npaum li qhov ua tau kom tsis txhob muaj kev suav tsis raug vim yog qhov yuam kev.
3. Nyob rau hauv kev siv, qhov hnyav ntawm carbon steel tubes tseem cuam tshuam los ntawm lwm yam, xws li vuam, corrosion, sab hauv phab ntsa hnav, thiab lwm yam, uas yuav tsum tau muab xam raws li cov kev mob tshwj xeeb.
Txoj kev suav ntawm steel qhov hnyav:
(1) Tag nrho qhov hnyav: Nws yog symmetry ntawm "net weight", uas yog tag nrho qhov hnyav ntawm cov hlau nws tus kheej thiab cov khoom ntim.
Lub tuam txhab tsheb thauj mus los suav cov khoom thauj raws li qhov hnyav tag nrho. Txawm li cas los xij, kev yuav thiab muag cov hlau yog xam los ntawm qhov hnyav.
(2) Net nyhav: Nws yog symmetry ntawm "tag nrho hnyav".
Qhov hnyav tom qab rho tawm qhov hnyav ntawm cov khoom ntim los ntawm qhov hnyav tag nrho ntawm cov hlau, uas yog, qhov hnyav tiag tiag, hu ua qhov hnyav.
Hauv kev yuav thiab muag cov khoom steel, feem ntau yog xam los ntawm qhov hnyav.
(3) Tare hnyav: qhov hnyav ntawm cov khoom ntim steel, hu ua tare hnyav.
(4) Qhov hnyav hnyav: chav ntsuas qhov hnyav siv thaum xam cov nqi thauj khoom raws li qhov hnyav tag nrho ntawm cov hlau.
Chav ntsuas kev cai lij choj yog tus tuj (1000kg), thiab tseem muaj tons ntev (1016.16kg hauv British system) thiab luv tons (907.18kg hauv Teb Chaws Asmeskas system).
(5) Tus nqi them nqi: tseem hu ua "billing ton" lossis "freight ton".
Qhov hnyav ntawm cov hlau uas lub tsheb thauj mus los them tus nqi thauj khoom:
Cov kev thauj mus los sib txawv muaj cov qauv kev suav thiab cov txheej txheem sib txawv.
Xws li kev tsheb ciav hlau tsheb thauj mus los, feem ntau siv cov cim npe ntawm lub tsheb thauj khoom raws li qhov hnyav ntawm kev them nqi.
Rau kev thauj mus los, tus freight yog them raws li lub tonnage ntawm lub tsheb.
Rau qhov tsawg-tshaj-tsheb thauj khoom ntawm railways thiab txoj kev loj, qhov tsawg kawg nkaus them tus nqi yog raws li qhov hnyav tag nrho ntawm ob peb kilograms, thiab sib npaug yog tias nws tsis txaus.
Daim ntawv thov ntawm carbon steel tubes:
Cov pa roj carbon steel raj yog dav siv hauv kev tsim kho, roj av, tshuaj lom neeg kev lag luam, tshuab, nkoj, tsheb, aviation thiab ntau yam haujlwm. Nws yog tus cwj pwm los ntawm lub zog siab, zoo corrosion kuj, kev ua haujlwm zoo heev, lub teeb yuag, tus nqi qis, thiab lwm yam. Nws plays lub luag haujlwm tseem ceeb hauv ntau yam lag luam.
