Dab tsi yog qhov txawv ntawm ob txoj kev tsim ntawm submerged arc vuam steel yeeb nkab
Feem ntau, longitudinal submerged arc welded steel kav siv nyob rau hauv roj av pipeline engineering yog tsim los ntawm UOE thiab JCOE. Cov txheej txheem ntau lawm yog tias tom qab cov yeeb nkab steel dawb yog tsim los ntawm UO lossis JCO, ua ntej vuam, sab hauv thiab sab nraud kawg vuam, txoj kab uas hla kev nthuav dav, kev tshuaj xyuas tsis zoo, cov yeeb nkab kawg ua tiav, ntsuas dej siab, ntsuas qhov ntsuas thiab ntev, thiab tshuaj xyuas qhov pom. ntawm steel yeeb nkab cim yog nqa tawm. Hnub no, cia peb kawm txog cov yam ntxwv ntawm UOE thiab JCOE!
Hauv UOE txoj kev tsim, ua ntej, cov npoo ntawm cov phaj hlau yuav tsum tau bevelled, leveled thiab khoov, ces nias rau hauv U-puab los ntawm lub tshuab tsim, thiab tom qab ntawd khoov rau hauv O-puab. Tom qab cov yeeb nkab steel raug kaw, roj shielded vuam yog siv rau pre-welding, submerged arc vuam yog siv rau sab hauv thiab sab nraud kawg vuam, thiab thaum kawg tag nrho cov yeeb nkab lub cev yog txias-expanded los ntawm ib tug sectional mechanical expanding txheej txheem. Tom qab cov yeeb nkab steel tau tsim thiab welded, ib qho kev tshuaj xyuas yog nqa tawm. Cov tshuab no yog siv ntau tshaj plaws, paub tab thiab paub txog cov tshuab tsim khoom ntawm txoj kab uas hla loj longitudinal submerged arc welded yeeb nkab nyob hauv lub ntiaj teb.
Cov yam ntxwv tseem ceeb ntawm UOE welded steel yeeb nkab:
1) Cov txheej txheem tsim yog sib cais los ntawm cov txheej txheem vuam, uas belongs rau cov khoom siv tsis tu ncua.
2) Thick-walled steel kav tuaj yeem tsim tau, thiab qhov siab tshaj plaws phab ntsa thickness tuaj yeem ncav cuag li 4Omm.
3) Raws li qhov ntev, qhov ntev ntawm cov yeeb nkab steel tsuas yog ib nrab ntawm cov kauv vuam, yog li qhov tshwm sim ntawm qhov tsis xws li vuam yog tsawg.
4) Cov zis yog siab, thiab cov zis ntawm ib chav UOE feem ntau sib npaug rau tag nrho cov zis ntawm 2 ~ 4 kauv welded yeeb nkab units.
5) Txoj kab uas hla nthuav dav yog siv los txhim kho lub zog thiab qhov tseeb ntawm cov yeeb nkab steel.
6) UOE steel yeeb nkab yog ncaj seam, uas ua rau cov kav dej tso thiab kev saib xyuas yooj yim dua.
7) Cov khoom siv loj dua li cov kauv welded yeeb nkab zeb, thiab cov nqi peev yog siab.
Piv nrog UOE molding txoj kev, JCOE molding txheej txheem muaj qhov zoo ntawm tus nqi qis, cov txheej txheem muaj zog adaptability, me me ntawm molding tuag thiab lub teeb molding tuag, thiab nws cov cuab yeej thiab cov khoom siv dav siv. JCOE cov yeeb nkab ua cov txheej txheem yog tsim cov hlau phaj hauv qhov kev txiav txim ntawm JCO-forming, pre-weld cov yeeb nkab steel los ntawm cov roj shielded vuam tom qab sib koom ua ke, thiab tom qab ntawd ua rau sab hauv thiab sab nraud kawg vuam los ntawm submerged arc vuam. Thaum kawg, tag nrho cov yeeb nkab lub cev yog txias-expanded los ntawm sectional mechanical expanding process, thiab thaum kawg ib tug series ntawm kev soj ntsuam yog nqa tawm.
Cov yam ntxwv tseem ceeb ntawm JCOE txheej txheem:
1) Txhua txoj kev tsim ntawm JCOE tau ua tiav ntawm cov xovxwm loj, uas yuav tsum tau ua haujlwm siab rau cov yeeb nkab steel shaping lag luam thiab siv sijhawm ntev rau lub tsev tsim. Vim muaj ntau yam molding, piv nrog UOE cov txheej txheem, kev ua tau zoo yog tsawg, tab sis muaj tsawg dua pwm thiab cov cuab yeej siv qis dua. Yog li, tus naj npawb ntawm JCOE hauv tsev yog ntau dua li ntawm UOE units.
2) Vim tias JCO yog ntau kauj ruam nias, qhov tseeb qhov tseeb ntawm cov kav dej steel qis dua li ntawm UOE, yog li UOE steel kav feem ntau yog siv rau hauv cov kav dej sab nrauv.
Kev tswj hwm ntawm JCO molding:
Nyob rau hauv JCO txoj kev tsim, cov hlau phaj yog maj mam xa mus rau hauv lub molding pwm los ntawm steel pusher, thiab nws yuav tsum tau muab straightened dua ua ntej txhua sab yog tsim, thiab thaum kawg nws yog ua tiav rau hauv ib tug ncaj slotted steel yeeb nkab, thiab thaum kawg nws yog. welded thiab welded. JCO molding tshuab feem ntau txais kev tswj tsis siv neeg, thiab lub tshuab molding yog tsim rau luv luv stroke, thiab siab tshaj plaws tuaj yeem ncav cuag 9000t t.. Ua ntej hloov pauv tuag nrog cov kab sib txawv, ntxuav cov impurities ntawm lub hauv siab tuag ncoo kom ntseeg tau tias qhov qis qis. ncoo yog tiaj tus tom qab thauj khoom, thiaj li tsis cuam tshuam rau qhov tseeb ntawm qhov kev taw qhia tuab.
