ERW steel yeeb nkab raug tsim yog ib qho kev sib txuas txuas ntxiv thiab cov txheej txheem vuam uas hloov cov hlau kauj mus rau qhov raug qhov ntev ntev welded yeeb nkab. Txoj kev tsim khoom sib txuas ua ke steel npaj, yob txoj kev, siab- zaus vuam, sizing, txiav, tshuaj xyuas, thiab ua tiav cov haujlwm.
Kev nkag siab txog cov txheej txheem tsim khoom pab cov neeg yuav khoom thiab cov kws tsim khoom ntsuas qhov zoo thiab tsim nyog ntawm ERW steel yeeb nkab. Cov yeeb nkab tiav tsis yog txiav txim siab los ntawm kev vuam ib leeg. Qhov zoo ntawm cov khoom siv raw, tsim kev ruaj ntseg, vuam tsis, kev tswj qhov ntev, kev tshuaj xyuas cov txheej txheem, thiab kev ua tiav tag nrho cuam tshuam kev ua haujlwm kawg.
Yuav ua li cas ERW Steel Pipe Manufacturing Process pib?
Thawj theem ntawm ERW steel yeeb nkab ntau lawm yog raw khoom npaj. Steel coils raug xaiv raws li qib yuav tsum tau, tshuaj muaj pes tsawg leeg, thickness, dav, thiab txhua yam khoom. Cov khoom xa tuaj raug tshuaj xyuas ua ntej nkag mus rau hauv cov kab ntau lawm.
Lub coil yog uncoiled thiab ua tiav rau hauv ib txoj hlua hlau txuas ntxiv. Nyob ntawm cov txheej txheem tsim khoom, kev npaj ntug thiab lwm yam kev ua haujlwm ua ntej yuav raug ua ua ntej tsim. Lub sawb yuav tsum muaj qhov dav ruaj khov thiab tuab vim tias qhov sib txawv ntawm cov khoom siv nkag tuaj yeem cuam tshuam rau qhov kawg ntawm cov yeeb nkab qhov ntev.
Steel Chev Kev Npaj thiab Roll Forming
Roll forming yog ib qho ntawm cov theem tseem ceeb tshaj plaws hauv ERW steel yeeb nkab ntau lawm. Ib lub tiaj steel strips dhau los ntawm ib ntu ntawm kev ua cov yob uas maj mam khoov nws mus rau hauv ib lub voj voog lossis ze rau - lub voj voog.
Lub hom phiaj yog kom ua tiav cov duab geometry ruaj khov yam tsis tsim kom muaj ntau qhov deformation lossis kev ntxhov siab. Kev tsim qauv tsim ua qhov tseem ceeb dua li cov yeeb nkab txoj kab uas hla thiab phab ntsa thickness hloov.
Tswj txoj kab sib sau
Tom qab cov sawb tau tsim rau hauv cov duab qhib cylindrical, nws cov npoo ntev yog positioned opposite ib leeg. Cov ntug kev mob yog ua tib zoo tswj vim qhov zoo ntawm cov weld nyob ntawm ib feem ntawm kev sib tw thiab kev huv ntawm cov npoo.
Nyob rau theem no, ntau lawm ceev, yob sib dhos, sawb nro, thiab kev tsim siab yuav tsum nyob ruaj khov. Txhua qhov sib txawv tseem ceeb tuaj yeem cuam tshuam cov yeeb nkab ncaj, txoj kab uas hla, lossis qhov chaw vuam.
| Kev tsim khoom theem | Lub Hom Phiaj | Hom Kev Tswj Xyuas Zoo |
|---|---|---|
| Coil tshuaj xyuas | Paub meej tias raw khoom zoo | Chemical thiab mechanical cov ntaub ntawv |
| Uncoiling | Npaj nruam nruam | Surface thiab dimensional soj ntsuam |
| tsim | Tsim cov yeeb nkab zoo | Txoj kab uas hla, sib dhos thiab ua kom ruaj khov |
| HFW / ERW vuam | Koom nrog longitudinal ntug | Welding parameters thiab weld kev ncaj ncees |
| Qhov loj me | Ua kom tiav qhov ntev | Sab nraud txoj kab uas hla thiab roundness |
| Ncaj ncaj | Tswj kev ncaj | Kev ntsuas ncaj |
| Txiav | Tsim kom muaj qhov ntev | Ntev ntev |
| Kev tshuaj xyuas | Tshawb xyuas cov khoom ua raws cai | NDT, hydrostatic thiab kev kuaj pom |
| Ua tiav | Npaj cov yeeb nkab rau kev xa khoom | Beveling, marking, txheej thiab bundling |
Lub vuam theem ua raws li kev tsim. Siab - zaus hluav taws xob tsim hluav taws xob tsim hluav taws xob hauv cheeb tsam ntawm cov npoo npoo. Cov npoo rhuab yog ces yuam ua ke nyob rau hauv siab los tsim ib tug nruam longitudinal seam.
Qhov tseeb welding tsis nyob ntawm cov khoom siv qib, phab ntsa thickness, yeeb nkab txoj kab uas hla, ntau lawm ceev, thiab cov khoom configuration. Ua kom ruaj khov vuam tej yam kev mob yog ib qho tseem ceeb vim hais tias cov kev hloov nyob rau hauv lub tshav kub input los yog siab yuav cuam tshuam rau lub weld cheeb tsam.
Tom qab vuam, cov yeeb nkab nkag mus rau qhov loj thiab cov khoom tiav. Sizing rolls kho cov yeeb nkab profile thiab tsim qhov kawg sab nraud txoj kab uas hla. Cov cuab yeej ncaj nraim tuaj yeem txhim kho txoj kab ntev ntev.
Cov yeeb nkab yog tom qab txiav rau hauv qhov ntev ntev. Nyob ntawm tus neeg siv khoom tshwj xeeb, qhov kawg yuav yog dawb, beveled, threaded, lossis lwm yam ua tiav.
Kev tshuaj xyuas yog ib feem tseem ceeb ntawm kev tsim khoom. Kev tshuaj xyuas qhov muag saib xyuas qhov zoo thiab qhov tsis xws luag, thaum qhov kev tshuaj ntsuam xyuas pom tseeb sab nraud, phab ntsa thickness, ntev, thiab ncaj.
Tsis yog-Kev kuaj kev puas tsuaj tuaj yeem siv rau cov vuam seam lossis tag nrho cov yeeb nkab nyob ntawm tus qauv thiab qhov yuav tsum tau ua. Kev ntsuam xyuas hydrostatic kuj tseem tuaj yeem ua rau cov khoom tsim los rau kev pabcuam siab lossis cov kav dej.
Thaum kawg, cov kav dej tuaj yeem tau txais cov txheej txheem sab nraud lossis sab hauv qhov xav tau. Cov txheej txheem tiv thaiv corrosion feem ntau suav nrog FBE, 2PE, 3PE, 2PP, 3PP, sab hauv epoxy hmoov, thiab kua epoxy systems.
Cov kav dej tiav tom qab ntawd raug cim nrog cov ntaub ntawv tseem ceeb xws li tus qauv, qib, qhov loj me, tus lej xov tooj cua sov, kev txheeb xyuas cov chaw tsim khoom, thiab lwm cov ntaub ntawv traceability. Kev ntim khoom kom zoo thiab kev tiv thaiv npaj cov khoom rau kev khaws cia, kev thauj mus los, thiab kev teeb tsa qhov project.
Qhov ua tau zoo ntawm cov txheej txheem txuas ntxiv no yog ib qho ntawm cov txiaj ntsig tseem ceeb ntawm ERW steel yeeb nkab. Piv nrog rau cov kev tsim khoom uas xav tau ntau tus neeg ua haujlwm theem, cov kab ERW niaj hnub tuaj yeem ua tiav cov txiaj ntsig siab thaum tswj qhov ntev.
Rau cov haujlwm thoob ntiaj teb, txawm li cas los xij, kev tsim khoom ceev yuav tsum tsis txhob hloov kev tswj xyuas zoo. Cov chaw tsim khoom lag luam txhim khu kev lag luam yuav tsum sib npaug ntawm cov khoom lag luam nrog cov txheej txheem kev ruaj ntseg, kev soj ntsuam vuam, kev txheeb xyuas qhov ntev, kev ntsuas tshuab, thiab kev taug qab.
ERW steel yeeb nkab tsim yog li ntawd sawv cev rau ib qho kev sib koom ua ke es tsis yog ib qho kev ua haujlwm vuam. Los ntawm kev xaiv cov hlau kauj mus rau qhov kawg tshuaj ntsuam thiab txheej, txhua theem ua rau kev ua haujlwm zoo thiab kev pabcuam ntawm cov yeeb nkab tiav.
