1.1 Qhov tseem ceeb ntawm qhov hnyav kwv yees hauv cov yeeb nkab engineering
Steel Yeeb Nkab Nyaj yog qhov tseem ceeb heev hauv kev tsim qauv engineering, logistics, thiab npaj kev teeb tsa. Cov ntaub ntawv hnyav hnyav ua kom muaj txiaj ntsig uas cov kav dej ua yeeb yam nyab xeeb thaum nyob hauv kev caij tsheb thauj mus los thiab kev txwv.
1.2 Txheej txheem cej luam ntawm cov yeeb nkab loj
Muaj peb hom kev tsim khoom lag luam hauv cov yeeb nkab kev lag luam steel:
- ERW (hluav taws xob tiv thaiv welded)
- Swshaw (kauv submerged arc welded)
- Seamless Steel Yeeb Nkab
Txhua ntawm cov pawg no muaj qhov txawvCov txheej txheem tsim khoom, cov ris tsho phab ntsa, thiab cov yam ntxwv hnyav, coj rau kev ua tau zoo thiab cov ntaub ntawv thov. Nkag siab txog lawv tus cwj pwm nyhav yuav pab engineers thiab cov neeg yuav khoom tsim kev txiav txim siab yog.
2. ERW (hluav taws xob tiv thaiv welded) yeeb nkabCov yam ntxwv hnyav
2.1 Yuav ua li cas ERW kav yog tsim
ERW kav yog tsim los ntawmtxias - kev sib sau kub -}} rolled steel coilsmus rau hauv cov duab cylindrical thiab vuam cov npoo ntev siv hluav taws xob hluav taws xob. Tus txheej txheem no muab cov kav dej nrogCov Khaub Ncaws Tawm Tawm Tawm (OD)thiabxwm yeem phab ntsa tuab{{0- qhov zoo tagnrho rau high- heev volume, precision- driven cov ntawv thov.
2.2 Cov khaub ncaws hnav khaub ncaws tuab thiab muaj kev sib xws
Ib qho ntawm cov lus txhais tau zoo ntawm ERW steel kav yog lawvnruj medensional tswjCov. Vim tias lub phab ntsa tuab tseem niaj hnub hnav thoob plaws ntawm cov yeeb nkab ntev, theoretical thiab qhov hnyav tiag tiag li dlhib zoo. Qhov precision no ua rau ERW kav txhim khu kev qha rau qhov hnyav- raws li kev suav.
2.3 Cov Qauv Txheej Txheem thiab Cov Lus Qhia Tshwj Xeeb
ERW kav feem ntau yog tsim nyob hauv txoj kev lees paub thoob ntiaj teb lees paub xws li:
- ASTM A53 / A500 (US)
- EN 10217 / EN 10219 (Tebchaws Europe)
- API 5L (roj thiab roj kis)
Cov qauv txheej txheem no tsis yog tsuas yog phab ntsa tiv thaiv thiab lub zog siv zog tab sis kuj tso cai hnyav tiag tiag {}} feem ntau±5%Rau cov qauv siv thiab±3.5%Rau cov roj thiab roj apps.
2.4 Raug nyhav li
Piv txwv li, aDN150 (NPS 6)ERW steel yeeb yuav muaj cov hnyav no theoretical:
| Teem caij | Txheej hauv lub taub (mm) | Phab Ntsa Thickness (Mm) | Theoretical hnyav (kg / m) |
|---|---|---|---|
| Sch 20 | 168.3 | 4.78 | 18.8 |
| Sch 40 | 168.3 | 7.11 | 27.3 |
| Sch 80 | 168.3 | 10.97 | 41.5 |
Cov kev ntseeg no muaj kev sib xws thoob plaws vim yog Huayang'sKev ua tshuab siab tshuab thiab vuam tshuabuas txo qis kev sib txawv.
3. Ssaw (kauv submerged arc welded) yeeb nkabQhov hnyav yam
3.1 Muab kauv tsim
Ssaw kav, tseem hu uaMuab kauv welded kav, yog ua los ntawm kev sib sau cov phiaj hlau lossis coils rau hauv cov kauv thiab vuam raws cov leeg. Qhov no tso cai raudiamool loj dua- txog li 1422 hli lossis ntau dua - ua cov pipes zoo nkauj rauRoj, Roj, thiab Dej Kis Tau Dej Pip.
3.2 yam cuam tshuam muaj teeb meem
Qhov hnyav ntawm ssaw pipes tuaj yeem sib txawv me ntsis ntau dua li ERW vim muaj ntau tus qauv thiab txheej txheem {{}}} tej yam ntsig txog:
- Vuam sib tshooj: Cov leeg sib txig qhia cov khoom siv sib tshooj sib tshooj, ntxiv 1-3% rau tag nrho cov hnyav ib meter.
- Phab Ntsa Thickness Variation: Thicker phab ntsa (feem ntau 7-50 mm) loj hlob nce tag nrho pawg.
- Cov Khaub Ncaws Tiv Thaiv: Cov txheej txheem sab nraud sab nraud xws li3PE, epoxy, lossis bitumentuaj yeem ntxiv txog 5-10% qhov hnyav ntxiv.
3.3 Piv txwv li Ssaw LSAWW
| Inch (hli) | Phab Ntsa Thickness (Mm) | Ntev (m) | Kwv yees li. Nyhav (kg / m) |
|---|---|---|---|
| 406.4 | 8.0 | 12 | 79.5 |
| 610 | 10.0 | 12 | 140.8 |
| 1016 | 14.0 | 12 | 275.5 |
| 1422 | 18.0 | 12 | 472.3 |
Cov kev ntseeg no pom tias swsaw kav yog qhov tseem ceebhnyav rau ib lub ntsuasTshaj li ERW kav vim muaj qhov loj thiab cov kev xav tau.
3.4 Daim ntawv thov thiab qhov hnyav cuam tshuam
Vim lawvSiab Ntsuas Lub Peev Xwmthiabdiam loj loj, SSAW kav yog feem ntau siv nyob rau hauvNtev - deb nrug kev kis pipelinesQhov twg cov ntws ntim outweighs yuag hnyav. Huaayang's swsaw kab yog nruab nrogLub Nruab weld tsis siv neeg weld, kom ntseeg tau ob qho tib si kev ncaj ncees thiab sab nraud precision.
4. Seamless cov yeeb nkab hnyav thiab ntom sib txawv
4.1 Lub Seamless Cov Txheej Txheem
Seamless steel kav yog tsim los ntawm tho cov khoom noj ntses hauv qab kub, tom qab ntawd elongating lawv mus rau hauv lub kaus mom khoob. Cov qauv no tshem tawm Weld nqaws, muabSuperior siab kam thiab cov qauv kev ntseeg.
4.2 Vim li cas thiaj sib txawv kav dej sib txawv
Tsis zoo li welded kav, seamless kav feem ntau muajCov txiaj ntsig ntau duaTab sis yuav nthuav tawm me meTxheej txheej strawVim tias kub dov. Lawv cov hnyav npaum li casme ntsis siab duaTshaj li ERW sib npaug vim tuab towances thiab denser khoom xa khoom.
4.3 Piv txwv li qhov hnyav sib piv
| Ntaus | DN150 (NPS 6) | Phab Ntsa Thickness (Mm) | Theoretical hnyav (kg / m) |
|---|---|---|---|
| Hlob | 168.3 | 7.11 | 27.3 |
| Tussaw | 168.3 | 7.11 | 28.1 |
| Tsis ntse | 168.3 | 7.11 | 28.6 |
Lub rooj qhia tau hais tias thaum qhov sib txawv tshwm me, hauv cov phiaj xwm loj (pua pua ntawm cov hlau), qhov no tuaj yeem txhais rau ob peb metric tons ntawm kev sib txawv.
4.4 Cov Khoom Siv Ntsej Muag Ntsej Muag
Tus qauv ntom ntawm cov pa roj carbon steel siv rau erw thiab ssaw kav dej yog7.85 g / cm³, tab sis seamless kav dej tuaj yeem ncav cuag me ntsis siab dua vim muaj kev sib dhos zoo thaum dov. Qhov no ua rau lawv zoo tagnrho rauhigh - h siab, siab -}} qhov chaw ib puag ncigZoo li kev ua kom zoo dua thiab cov nroj tsuag fais fab.
