Qhov txawv ntawm uoe thiabjc cev

Loj-caliber, siab xa khoom siab, kev thauj mus los ntev thiab ntau hom kev thauj khoom nruab nrab yog lub cim tseem ceeb ntawm kev lag luam kev lag luam thev naus laus zis, tab sis kuj yog cov qauv dav dav ntawm txoj kev lag luam pipeline.Nrog rau txoj kev loj hlob ntawm Tuam Tshoj txoj kev lag luam roj, cov roj kab, thib ob-kab, thiab lwm yam kev lag luam loj tsis tu ncua, txoj kab uas hla loj, phab ntsa thickness ntawm cov raj xa dej siab, zoo heev rau kev thov.Cov tsoos kauv seam welded yeeb nkab tsis tuaj yeem ua tau raws li qhov yuav tsum tau muaj ntawm lub peev xwm thiab kev nyab xeeb kev ua tau zoo, txoj kab uas hla loj, phab ntsa tuab, qib siab LSAW kav los hloov cov kauv welded yeeb nkab tau dhau los ua ib qho kev sib txawv.LSAW yeeb nkab txhim khu kev qha zoo, tau dav siv nyob rau hauv txawv teb chaws lub teb chaws rau cov roj thiab roj ntawm high-voltage kis kab mob.Nyob rau hauv xyoo tas los no, lub teb chaws kuj tseem yuav maj mam tsim LSAW yeeb nkab tsim muaj peev xwm, mainstream yeeb nkab UOE thev naus laus zis thiab JCOE ntawm thev naus laus zis.

Nrog rau kev txhim kho ntawm qib steel, kev tsim cov kav dej, txoj kab ncaj nraim submerged arc welded yeeb nkab los ua thawj qhov kev xaiv ntawm feem ntau ntawm cov kab hauv lub cev, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig hnyav, cov neeg nyob hauv marine pipeline."West-East Gas Pipeline Project, rau ob, peb, plaub hom loj caliber ncaj seam submerged arc welded yeeb nkab, 14% yog ua JCOE raj, thiab tus so yog imported UOE yeeb nkab.

Kev tsim khoom ntawm UOE thiab JCOE, cov khoom sib txawv sib txawv

Kev pom los ntawm ob txoj kev tsim khoom, ob qho tib si hauv cov txheej txheem ntawm kev tsim cov pem hauv ntej thiab nram qab yog qhov zoo ib yam, qhov sib txawv loj tshaj plaws yog txoj kev molding.UOE txoj kev tsim feem ntau muaj ob kauj ruam: U ua thiab O molding.Thiab JCOE tsim ib feem ntawm qhov kev zov me nyuam tau muab faib ua rau feem, kev tsim khoom tau txo qis heev.Txoj kev sib txawv, ua rau UOE thiab JCOE qhov sib txawv ntawm txoj kab uas hla, phab ntsa thickness, qhov ntev, ntau lawm efficiency, yield ratio.

UOE kab yeeb nkab thiab JCOE ntawm cov yeeb nkab yeeb nkab los ntawm kev sib piv ntawm cov txheej txheem tsim khoom thiab cov nqi tsim khoom, cov lus xaus hauv qab no:

(1) UOE ntau lawm efficiency, muaj peev xwm, thiab hloov pwm lub sij hawm ntev dua, haum rau ntau lawm

(1) UOE ntau lawm efficiency, muaj peev xwm, thiab hloov pwm lub sij hawm ntev, tsim nyog rau ntau lawm, cov khoom ntawm ib tug specification;ntau lawm JCOE tsis tshua muaj txiaj ntsig, pwm sib haum rau ntau yam kev qhia tshwj xeeb, tsim nyog rau kev tsim cov ntim me me, ntau cov khoom tshwj xeeb.

(2) UOE tsim cov khoom lag luam kab ntau thiab tuab yuav tsum tsawg dua JCOE, tab sis muaj peev xwm ua tau raws li qhov yuav tsum tau ua ntawm qhov project.

(3) Los ntawm qhov kev ua tau zoo ntawm qhov pom, UOE kab yeeb nkab piv JCOE qhov muaj kev ntxhov siab seem, siab precision Dimensions yield zoo dua me me.
