Steel Yeeb Nkab Nyaj yog ib qho ntawm cov tsis tseem ceeb tshaj plaws hauv engineering tsim qauv, logistics, thiab kev ua tiav. Txawm hais tias koj tab tom npaj phiaj xwm txheej txheem lossis thauj cov khoom loj ntawmkav dej, Nkag siab yuav ua li cas xam qhov hnyav hnyav ntawm cov yeeb nkab pab kom ua kom paub tseeb tias qhov tseeb hauv ob qho kev kwv yees thiab kev ua haujlwm.
1. Qhov tseem ceeb ntawm cov pa yeeb hnyav
1.1 Vim li cas paub cov yeeb nkab hnyav
Qhov hnyav ntawm cov yeeb nkab cuam tshuam kev tuav, thauj khoom, tsim qauv qauv, thiab tag nrho cov nqi. Piv txwv li, thaum tsim kev txhawb nqa lossis suav nrog kev thauj khoom, cov kws tsim lag luam yuav tsum paub txog qhov hnyav ntawm txhua cov yeeb nkab kom muaj kev nyab xeeb thiab ua haujlwm.
1.2 Kev thov hla kev lag luam
Los ntawm cov roj thiab roj kev sib kis mus rau dej rau dej, kev tsim kho, thiab cov machinery tsim kho, thiab kev ntseeg tau ruaj khov, thiab kev tswj hwm tus nqi, thiab tus nqi tswj hwm hauv txhua hom.
2. Cov mis rau xam cov yeeb nkab hlau hnyav
2.1 Qhov yooj yim sib npaug
Theoretical yeeb nkab hnyav (w) yog xam siv cov qauv hauv qab no:
W=(ed - × × wt × 0.02466 × l
Qhov twg:
W= hnyav (kg)
Od=} sab nraud ntawm lub cheeb (hli)
Wt=} Ntsa Thickness (hli)
L= ntev (m)
0.02466{{0= Cov ntom ntom nti tas li (raws li 7.85 g / cm³)
Qhov kev sib npaug no muab cov roj carbon steel hlau hluav taws xob raws li lawv cov nominal loj, phab ntsa tuab, thiab ntev.
2.2 Cov lus qhia yooj yim rau ib- 'meter luj
Yog tias koj tsuas yog xav tau qhov hnyav rau ib lub ntsuas dej, siv:
W=(ed - wt × × wt × 0.02466
Qhov no pab tau tias muaj qhov loj tshaj qhov chaw tsis muaj qhov ntev.
3. Piv txwv: kev suav hnyav rau ib qhoHlau Yeeb Nkab
3.1 Kauj Ruam {- {{2}- Qaib Xam
Nqa aCarbon Steel ERW YEEB NKABNrog:
Cov taub uas hla=114.3 hli (nps 4)
Phab Ntsa Thickness=6.02 hli (Sch 40)
Ntev=6} meters
Tom qab ntawd:
W = (114.3 – 6.02) × 6.02 × 0.02466 × 6
W ≈ 97.3 × 6.02 × 0.02466 × 6
W ≈ 86.7 kg ib 6 m ntev
3.2 Kev Txhais Lus
Qhov no txhais tau tias tus qauv Nps 4 Teem Yug 40 tus yeeb nkab hnyav txog14.45 kg / mCov. Daim duab no yog siv hauv kev npaj cov ntaub ntawv npaj thiab cov neeg kho tshuab los kwv yees tag nrho cov khoom hnyav.
4. Cov hlau nplaum hlau hnyav los ntawm qhov loj me
4.1 Cov Yeeb Nkab Cov Hlau Nyias Rau Ib Meter
Hauv qab no yog daim ntawv qhia siv siv rau cov khoom siv thiab seamless steel kav.
| Nominal loj | Txheej hauv lub taub (mm) | Phab Ntsa Thickness (Mm) | Nyhav (kg / m) | Teem caij |
|---|---|---|---|---|
| NPS 1 (DN25) | 33.4 | 3.38 | 2.52 | Sch 40 |
| NPS 2 (DN50) | 60.3 | 3.91 | 5.44 | Sch 40 |
| NPS 3 (DN80) | 88.9 | 5.49 | 10.92 | Sch 40 |
| Nps 4 (DN100) | 114.3 | 6.02 | 14.45 | Sch 40 |
| Nps 6 (DN150) | 168.3 | 7.11 | 25.11 | Sch 40 |
| NPS 8 (DN200) | 219.1 | 8.18 | 36.76 | Sch 40 |
| NPS 10 (DN250) | 273.1 | 9.27 | 52.44 | Sch 40 |
4.2 Lus Cim rau ntawm daim duab
Daim duab muabQhov hnyav tshaj plawstsuas yog; Qhov hnyav tiag tiag yuav sib txawv me ntsis vim cov khoom muaj pes tsawg leeg thiab tsim kev thev taus.
Rau stainless hlau, muab ntau los ntawm qhov chaw ua tuab ntawm0.99, txij li Stainless hlau muaj qis dua qis dua cov hlau.
5. Qhov ntau cuam tshuam rau cov yeeb nkab steel hnyav
5.1 Thuab Phab Ntsa Thuab thiab Sijhawm
5.1.1 Toag cov sijhawm
Cov txheej yeeb nkab xws li sch 20, sch 40, Sch 80, thiab Sch 160 txhais cov phab ntsa sib txawv rau tib lub npe sib txawv.
5.1.2 Piv txwv li: NPS 4 Yeeb
| Teem caij | Phab Ntsa Thickness (Mm) | Nyhav (kg / m) |
|---|---|---|
| Sch 20 | 4.78 | 11.5 |
| Sch 40 | 6.02 | 14.45 |
| Sch 80 | 8.56 | 19.8 |
| SCH 160 | 13.49 | 29.8 |
Thicker phab ntsa nce ntxiv rau ob lub zog thiab qhov hnyav, txo cov yeeb nkab lub hauv taub hau thiab dej muaj peev xwm.
5.2 Khoom Hom thiab Nraum
Cov ntaub ntawv sib txawv muaj cov qauv sib txawv:
| Khoom Hom | Ntom ntom (g / cm³) | Qhov hnyav ntawm qhov hnyav |
|---|---|---|
| Cov Hlau Hlau | 7.85 | 1.00 |
| Stainless hlau | 7.93 | 1.01 |
| Alloy Steel | 7.80 | 0.99 |
| Galvanized steel | 7.85 | 1.00 |
Yog li, rau tib qhov loj me, stainless hlau kav hlau tiv thaiv me ntsis ntau dua li cov hlau steel.
6. Yuav ua li cas siv cov kab ke hnyav kom zoo
6.1 rau cov pab pawg ua haujlwm
Paub txog ib {- Qhov hnyav yuav pab kwv yees tag nrho cov khoom siv thiab cov nqi thauj khoom. Piv txwv li:
Yog tias 100 daim ntawm DN100 kav dej (6 m txhua) raug txiav txim:
14.45 kg / m × 6 m {100 =8670 kg tag nrho
6.2 Rau cov kws ua choj thiab cov qauv tsim
Cov ntaub ntawv hnyav hnyav txhawb kev nplua nuj kev suav nrog cov qauv thiab cov raj xa dej. Cov kws ua engineers Siv cov lej no los tsim cov kev txhawb nqa, xam cov khoom lag luam khoov, thiab ntsuas txhua qhov kev ua haujlwm tag nrho.
6.3 rau kev thauj thiab logistics
Muaj tseeb qhov hnyav suav Xam ua raws li kev thauj khoom nrog kev txwv cov kev txwv, crane muaj peev xwm, thiab kev nyab xeeb ntim thaum lub nkoj.
7. HUAYANG STEEFF YEEB NKAB: Precision hauv txhua lub ntsuas
7.1 kev tsim khoom ntau lawm thiab ntsuas
Huayang Steel Yeeb Nkab Haujlwm Erdated Erw thiab pom cov kab ntau lawm nrog tiag- lub sij hawm phab ntsa thickness xyuas thiab laser {}} online ntsuas. Cov kab ke no ua kom txhua cov pa taws qhov hnyav sib raug zoo rau cov qauv theoretical.
7.2 Cov Qauv Txheej Txheem Thoob Ntiaj Teb thiab Kev Zoo
Txhua yam khoom yoog tauASME B36.10M, Rau 10219, thiabAPI 5LCov lus qhia tshwj xeeb. Ua ntej xa tawm, txhua cov ntaub qhwv cov tshuab yeeb hauv cov pob zeb hydrostatic, pov thawj qhov ntev, thiab qhov hnyav ua piv txwv kom paub meej.
7.3 Kev txiav txim siab daws teeb meem rau cov neeg thoob ntiaj teb
Huayang muab kev cai txiav kom ntev thiab cov txheej txheem, ua kom pom kev zoo tuav thiab nruab rau cov phiaj xwm thoob plaws lub zog, thiab cov txheej txheem nruab nrab.
8. Xaus
Xam cov yeeb nkab tus yeeb nkab hnyav los ntawm qhov loj me yog qhov tseem ceeb rau txhua theem ntawm ib qhov project - los ntawm kev tsim los logistics. Theoretical lub cev hnyav cov qauv, sib xyaw nrog cov kab kos hnyav, tso cai rau cov engineers thiab cov neeg yuav khoom kwv yees tag nrho thauj, nqi, thiab kev ua haujlwm nrog kev ntseeg siab.
NtawmHUAYANG STEEFF YEEB NKAB, precision yog peb lub hauv paus. Txhua cov yeeb nkab yog tsim nrog nruj qhov tseeb kom tau raws li ob qho tib si nominal thiab cov kev xav tau. Seb puas rau siab - qhov teeb tsa siab, lossis kev xa tawm thoob ntiaj teb, peb xa cov khoom lag luam uas ua kom haum rau kev xav tau engineering.
