Seamless thiab welded steel tubes ua lub luag haujlwm tseem ceeb hauv cov khoom lag luam niaj hnub no.
Cov kev qhia tshwj xeeb ntawm cov raj no feem ntau txhais los ntawm cov kab uas hla (OD), phab ntsa thickness (WT) thiab ntev (L), thaum xam qhov hnyav ntawm lub raj steel yog raws li qhov ntsuas qhov ntsuas no ntxiv rau qhov ntom ntom (ρ) ntawm cov khoom siv. .Rau qhov phiaj xwm phiaj xwm, kev tswj hwm tus nqi thiab kev xa khoom, kev xam kom raug ntawm qhov hnyav ntawm cov yeeb nkab steel yog qhov tseem ceeb.Kab lus no nthuav tawm peb txoj hauv kev los xam qhov hnyav ntawm cov tubing steel thiab qhia tias yuav siv lawv li cas nrog cov qauv siv tau.
Basic xam cov yeeb nkab luj
Qhov hnyav ntawm cov yeeb nkab steel tuaj yeem kwv yees los ntawm kev suav nws qhov ntim tau los ntawm qhov ceev ntawm cov hlau.
Rau round steel kav (xws li seamless thiabwelded steel kav), qhov hnyav yog xam raws li hauv qab no:
Qhov hnyav(kg) = x (OD2-(OD-2 × WT)2) × L × r
ODyog sab nraud ntawm cov yeeb nkab steel hauv meters (m);
WTyog phab ntsa thickness ntawm cov yeeb nkab steel hauv meters (m);
Lyog qhov ntev ntawm cov yeeb nkab steel hauv meters (m);
ρyog qhov ceev ntawm cov hlau, rau cov pa roj carbon zoo tib yam, nws yog hais txog 7850kg / m3.
Simplified algorithm: imperial units
Qhov hnyav(lb/ft) = (OD (hauv) - WT (hauv)) × WT (hauv) × 10.69
qhov twg 10.69 yog ib qho tseem ceeb xam los ntawm qhov ceev ntawm cov hlau thiab chav tsev hloov dua siab tshiab siv los hloov qhov ntev ntawm nti mus rau phaus ib ko taw ntawm qhov ntev.
Piv txwv xam
Piv txwv li ib seem ntawmERW steel yeeb nkabnrog rau sab nraud txoj kab uas hla ntawm 10 ntiv tes thiab phab ntsa tuab ntawm 0.5 ntiv tes, xam qhov hnyav ib ko taw ntawm qhov ntev: Qhov hnyav (lb / ft) = (10-0.5) x 0.5 x 10.69
Qhov hnyav ib ko taw ntawm qhov ntev ntawm cov yeeb nkab steel yog kwv yees li 50.7775 phaus.
Simplified algorithm: metric units
Qhov hnyav (kg) = (OD-WT) × WT × L × 0.0246615
OD yog sab nraud ntawm cov yeeb nkab steel, hauv meters (mm);
WT yog phab ntsa tuab ntawm cov yeeb nkab steel hauv meters (mm);
L yog qhov ntev ntawm lub raj hauv meters (m);
0.0246615 yog raws li qhov ceev ntawm cov hlau (kwv yees li 7850 kg / m³) thiab ib chav tsev hloov pauv.
Piv txwv xam
Xav tias peb muaj ib tugseamless steel yeeb nkabnrog rau sab nraud txoj kab uas hla ntawm 114.3 hli, phab ntsa thickness ntawm 6.35 hli, thiab ntev ntawm 12 m.Xam qhov hnyav ntawm cov yeeb nkab siv cov qauv yooj yim saum toj no:
1. xam qhov txawv ntawm txoj kab uas hla thiab phab ntsa thickness: 114.3 - 6.35 = 107.95.2.
2. xam qhov hnyav los ntawm kev hloov cov mis: 107.95 × 6.35 × 12 × 0.0246615.3.
3. Qhov tshwm sim yog: 202.86
Yog li ntawd, tag nrho qhov hnyav ntawm cov yeeb nkab yog kwv yees li 202.86 kg.
Cov coefficients 10.69 thiab 0.0246615 hauv cov qauv yog raws li qhov nruab nrab ntom ntawm cov hlau.Cov hlau sib txawv (xws li stainless hlau, hlau alloy, thiab lwm yam) tej zaum yuav muaj qhov sib txawv thiab cov yam ntxwv yuav tsum tau kho kom haum.
Cov kev suav no muab kev kwv yees ntawm qhov hnyav ntawmseamlessthiab welded steel tubing.Vim muaj qhov sib txawv ntawm cov khoom ntom ntom, kev tsim kev kam rau siab, thiab lwm yam, qhov hnyav tiag tiag yuav txawv.
Qhov hnyav tiag tiag tuaj yeem sib txawv nyob ntawm kev ua haujlwm ntev thiab cov khoom siv ntom ntom, yog li cov qauv no yog kev kwv yees.Rau kev xam qhov tseeb ntawm qhov hnyav, nws raug nquahu kom koj xa mus rau cov ntaub ntawv muab los ntawm cov chaw tsim khoom lossis koj yuav ntsuas qhov tseeb.
Rau qhov tseeb engineering xam los yog kev lag luam hais, nws raug nquahu kom siv cov ntaub ntawv ntxaws ntxaws lossis cov neeg xa khoom ntawm cov yeeb nkab steel raug hu rau cov ntaub ntawv hnyav.
Kev ntsuas qhov hnyav ntawm cov yeeb nkab yog qhov tseem ceeb ntawm kev tsim qauv engineering thiab kev tswj hwm tus nqi, thiab kev nkag siab zoo thiab kev siv cov kev suav no yog siv rau cov yeeb nkab steel seamless nrog cov phab ntsa nyias nyias.Nyob rau hauv cov ntaub ntawv ntawm cov phab ntsa tuab heev seamless steel tubing, ntau txoj kev xam yuav tsum tau xav txog.
