Nws raug nquahu tias yuav tsum muaj cov neeg ua haujlwm nrog qib 3 ntsib txog EN473.
Kev tso cai ua haujlwm tau tshaj tawm los ntawm cov khw yuav tsum ua kom tau raws li cov cai ntawm cov txheej txheem sau.
Tsis yog-ua kev puas tsuaj kuaj yuav tsum tau ua los ntawm cov neeg ua haujlwm nrog qib 3 tso cai los ntawm cov khw.
NCO TSEG: Cov ntsiab lus ntawm Qib 1, 2 thiab 3 tuaj yeem nrhiav tau hauv cov lus qhia tshwj xeeb EN473 thiab EN10256.
Rau cov khoom siv siab hauv pawg IV (97/23-EC (23-23-EC
Qhov yuav tsum tau ua raws li cov kav hlau steel uas tsis tau raws li qhov no yuav tsum tau cim nrog "C2" tshwj tsis yog qhov xav tau ntawm "C1" yog saws (saib 3.3).
3.2 Cov yeeb nkab steel yuav tsum tsim los ntawm cov txheej txheem ntau lawm tau teev nyob hauv rooj 1.
Tshwj tsis yog xaiv 1 yog teev tseg, cov txheej txheem ntau lawm yuav tsum tau xaiv los ntawm cov khw.
Kev xaiv 1: Tus neeg yuav khoom yuav txiav txim siab cov phiaj xwm ntau lawm.
Lub submerged arc welds ntawm submerged arc welded kav welded yuav tsum muaj tsawg kawg ib weld txheej sab hauv thiab sab nraum cov yeeb nkab.
Txoj hlua ntawm cov yeeb nkab ntawm cov yeeb nkab tsim los rau kauv submerged arc vuam yuav tsum tsis pub tsawg tshaj li 0.8 npaug ntawm lub cheeb ntawm cov kab uas hla ntawm cov yeeb nkab ntawm cov yeeb nkab
Cov yeeb nkab tiav lawm yuav tsum tsis txhob siv Welds siv los txuas cov hlau txias lossis kub siv cov hlau ntev, lossis cov hlau tsim kom ua ntej tsim,
Tsuas yog spiral welds.
Rau cov kab ke ntawm submered arc welded steel kav hlau muaj cov txheej txheem vuam hlau, lawv yuav tsum ua raws li cov txheej txheem ntawm Welds uas tau raug tshuaj xyuas thiab xeem sib npaug rau cov tsiaj vib.
3.3 Kev ua haujlwm vuam yuav tsum ua los ntawm cov neeg ua haujlwm tsim nyog raws li cov kev ua haujlwm ua haujlwm.
Rau cov khoom siv siab hauv pawg pawg II, Kuv thiab IV (97/23-EC (23-23-as kev pom zoo los ntawm ib lub koom haum lees paub thib peb. Qhov yuav tsum tau ua raws li qhov yuav ua rau qhov kev xav tau no yuav cim "C1".
3.4 Cov vuam vuam rau submerged arc welded steel kav yuav tsum ua raws li cov cai ntawm Annex A.
3.5 EN10217 npog cov khoom xa tuaj ntawm cov yeeb nkab fittings. Saib Cov Lus 1
Tshwj tsis yog xaiv 2 tau teev tseg, cov chaw tsim khoom yuav tsum xaiv cov kev mob uas xa tuaj thaum nug thiab tso xaj.
