Longitudinal sub-arc welded kav luv luv rau lsaw yeeb nkab yog ib hom ntawm lsaw pipes tuaj yeem hnyav dua 50 hli, thaum sab nraum cov taub txwv rau 1420mmm utmost. LSAWAS GRASS muaj qhov kom zoo dua ntawm cov txheej txheem ntau lawm, muaj kev ua haujlwm siab, tus nqi tsawg.
Ob chav submed arc welded (dsaw) yeeb nkab yog hom kauv vuam thiab welded los ntawm cov khoom siv tsis siv neeg arc vuam txheej txheem. Yog li qhov ntev ntawm DSAWaw yeeb nkab tuaj yeem yog 40meters thaum ib qho ntev ntawm LSAW cov yeeb nkab tsuas yog 12 meters. Tab sis qhov siab tshaj plaws phab ntsa tuab ntawm dsaw kav dej tuaj yeem yog 25.4mm tsuas yog vim kev txwv ntawm cov coils kub.
Qhov zoo tshaj plaws feature ntawm kauv steel yeeb nkab yog tias cov taub loj tuaj yeem tsim cov kav hlau loj heev, Cangzhou Kap Steel Kav Nrog rau sab nraud ntawm txoj kab ntawm 3500 hli utmost. Thaum lub sij hawm tsim cov txheej txheem, lub steel chev yog deformed tusyees, cov kev ntxhov siab uas muaj me me, thiab sab saum npoo tsis kos. Cov txheej txheem kauv steel muaj ntau dua cov txheej loj, tshwj xeeb ntawm phab ntsa thickness, uas muaj qhov sib txawv ntawm lwm cov txheej txheem. Nws tuaj yeem ua tau kom tau raws li cov neeg siv ntawm cov neeg siv kauv cov yeeb nkab sib xws. Cov txheej txheem ua ntej-tog arc Txawm li cas los xij, piv nrog txoj kab ncaj ncaj nrog tib qhov ntev, lub weld ntev nce los ntawm 30 ~ 100%, thiab cov ceev ntau lawm.
