Stainless hlau welded kav tau seamless kho txij li xyoo 1970s. Lub teb chaws xws li Tebchaws Meskas, Nyiv, thiab Lub Tebchaws Yelemees twb tau pib tsim cov kav hlau stainless seamless welded kav los hloov qee cov kav dej seamless. Txog rau tam sim no, qee cov kav dej zoo thiab nyuaj roj kuj tuaj yeem ua nrog seamless kho welded kav. Ntawm cov seamless kho welded kav uas tsim los ntawm cov txheej txheem kub expansion shearing txoj kab uas hla, ntau lawm ntim ntawm seamless kho welded kav ranked thawj.
Piv nrog stainless hlau seamless kav, welded kav nrog seamless kev kho mob muaj qhov zoo ntawm tsawg peev nyob rau hauv cov kab ntau lawm, ntau lawm efficiency, ntau cov yeeb nkab phab ntsa, yooj yim tswj ntawm qhov ntev ntawm qhov ntev, thiab cov nqi qis dua rau qhov ntev-ntev ntau lawm. Cov txheej txheem tsim khoom siv cov txheej txheem kub nthuav dav thiab txoj kab uas hla ntawm cov txheej txheem siab ncaj seam welded kav kom ua tiav seamless kev kho mob, nrog ntau dua qhov tseeb thiab phab ntsa thickness uniformity dua stainless hlau seamless kav. Mechanical zog, txheej txheem kev ua tau zoo, thiab tshuaj muaj pes tsawg leeg. Kev ua haujlwm compressive tuaj yeem ua tau raws li lub teb chaws tus qauv ntawm cov kav dej seamless. Nyob rau hauv industrialized lub teb chaws txawv teb chaws, cov qauv khoom ntawm stainless hlau kav yog tsim raws li kev ua tau zoo, tsis hais txog cov txheej txheem ntau lawm thiab cov txheej txheem. Ntev npaum li cov qauv yuav tsum tau ua thiab ua tau raws li qhov yuav tsum tau ua, lawv raug xa tawm thiab raug nqi raws li cov qauv sib xws. Cov kav hlau stainless nrog seamless kho nyob rau hauv domestic welded kav muaj peev xwm loj hlob zoo.
