ERWyog high-frequency kuj welding ncaj seam welded yeeb nkab;LSAWyog submerged arc vuam ncaj seam welded yeeb nkab;Ob leeg yog cov ncaj seam welded yeeb nkab, tab sis cov txheej txheem vuam txawv.Yog li koj tsis tuaj yeem hais ib qho ntawm lawv sawv cev ntawm txoj hlua ncaj nraim welded yeeb nkab.Ntau cov yeeb nkab steel yog SSAW- kauv welded yeeb nkab.High zaus ncaj seam (ERW) raws li cov txheej txheem vuam tau muab faib ua qhov sib txawv induction welding thiab tsis kam vuam ob daim ntawv, raws li kub dov dav ntim raws li raw khoom, los ntawm kev nruam, dabtsi yog khoov, vuam, kho cua sov, sizing, straightening, txheej txheem txiav.Piv nrog rau SSAW, qhov siab qhov tseeb, cov phab ntsa tuab tuab, zoo nto zoo, siab siab yog tag nrho cov txiaj ntsig.Tab sis qhov tsis zoo yog tias tsuas yog cov khoom me me txoj kab uas hla nyias phab ntsa yeeb nkab, weld yooj yim tiam resistant, tsis tiav fusion, trench corrosion tsis xws luag.Kev siv dav xws li lub nroog roj av, kev thauj mus los ntawm cov roj av.

Cov khoom siv ntawm LSAW steel yeeb nkab yog ib daim hlau tuab, cov hlau hauv pwm lossis molding tshuab nruab nrab-voltage (ntim), siv ob sab submerged arc vuam Nws cov khoom tiav specification ntau yog dav, lub toughness ntawm vuam, plasticity, zoo uniformity thiab compactness, nrog cov yeeb nkab loj txoj kab uas hla, phab ntsa thickness, muaj zog tsis kam mus rau kev kub siab, tsis tshua muaj kub corrosion kuj, thiab lwm yam. Nyob rau hauv kev tsim kho ntawm siab zog, siab toughness, siab zoo nyob rau hauv qhov ntev ntawm cov roj thiab roj pipeline, lub steel raj yog feem ntau loj txoj kab uas hla tuab phab ntsa ncaj seam submerged arc.Raws li cov kev cai ntawm API tus qauv hauv cov kav dej loj thiab cov pa roj, thaum qhov nce siab, hiav txwv thiab lub nroog cov neeg nyob hauv chav kawm 1, 2, ncaj seam submerged arc tsuas yog tsim rau cov raj hom.

Raws li txoj kev sib txawv tuaj yeem muab faib ua: UOE / JCOE / HME.Volumes ntawm kauv submerged arc (SSAW) yog nyob rau hauv cov kev taw qhia nrog rau hauv nruab nrab kab ntawm cov yeeb nkab txoj kev tsim lub kaum sab xis (adjustable), sib sau thiab vuam, vuam seam mus rau hauv kauv, qhov zoo yog tias nws muaj peev xwm tsim ntau yam specifications ntawm steel yeeb nkab txoj kab uas hla. Tib yam tshwj xeeb, cov khoom siv raw yog qhov loj dua, qhov vuam tuaj yeem zam qhov kev ntxhov siab ntawm lub hauv paus, qhov kev ntxhov siab yog qhov zoo, qhov tsis zoo yog qhov tsis zoo geometry, weld ntev piv nrog cov seam ntev, yooj yim los tsim cov kab nrib pleb, porosity, slag, weld defects. xws li vuam, vuam kev nyuaj siab yog tensile stress state.Cov kev cai thiab cov kev cai ntawm dav dav roj thiab roj kav ntev ntev tsim cov ntsia hlau Spiral submerged arc tsuas yog siv tau rau peb chav kawm, chav kawm.4 txawv teb chaws cov txheej txheem no yuav raug txhim kho raw cov ntaub ntawv es tsis txhob steel phaj, tsim thiab vuam, ces vuam thiab lean, txias expanding, tom qab vuam, vuam zoo yog ze rau UOE raj, nyob rau hauv tsev tsis muaj xws li cov txheej txheem, yog cov kev taw qhia ntawm peb lub Hoobkas los txhim kho."West-sab hnub tuaj roj" tseem yog siv los ntawm cov khoom siv tes ua ib txwm siv, tsuas yog cov yeeb nkab qhov loj.Tebchaws Asmeskas, Nyiv thiab Lub Tebchaws Yelemees, ntawm tag nrho, tsis zoo SSAW, tsis txhob xav tias nws tsim nyog siv SSAW pob tw;Canada thiab Ltalis ib feem siv SSAW, Lavxias teb sab, ib qho me me ntawm kev siv SSAW, thiab tau ua kom muaj kev sib koom ua ke nruj heev, vim muaj keeb kwm keeb kwm, feem ntau hauv lub cev kuj yog siv SSAW.
