EN 10217 Longitudinal submerged Arc Vuam (LSAWW)

Tshuaj Xyuas: Cov paib hlau siv rau kev tsim khoom yog thawj zaug kuaj rau ultrasonic kev sim ua kom ntseeg tau tias tsis muaj qhov tsis xws luag.

Ntug milling: Cov npoo ntawm cov phaj steel yog milled kom ua tiav qhov xav tau dav, palallelism, thiab bevel duab. Qhov no ua kom ntseeg tau tias cov npoo tau npaj kom zoo rau kev siv vuam.

Ua ntej dabtsi yog: Cov npoo ntawm cov phaj yog ua ntej-bent siv lub tshuab dabtsi yog khoov rau lawv cov nkhaus tsim nyog. Cov kauj ruam no yog qhov tseem ceeb rau kev sib sau cov yeeb nkab kom raug.

Kev sib sau: Lub phaj ua ntej yog tsim mus rau hauv tubular duab siv lub tshuab ua kom tau. Cov txheej txheem cuam tshuam rau nias lub phaj rau hauv "j" duab, tom qab ntawd "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C ". Cov kauj ruam no yog qhov tseem ceeb rau kev tsim cov geometry tseeb ntawm cov yeeb nkab.

Ua ntej-vuam: Cov yeeb nkab tsim tau ua ntej welded siv cov roj thaiv hluav taws xob vuam (Mag) los tsim cov leeg txuas ntxiv. Qhov kev pib no WELD pab tuav cov yeeb nkab ua ke ua ntej lub ntsiab vuam txheej txheem.

Nyob rau hauv vuam vuam: Sab hauv ntawm cov yeeb nkab yog welded siv tandem ntau cov tshuab dej hlau ua arc vuam (feem ntau nrog plaub xaim). Qhov no ua kom muaj zog siv Weld muaj zog thiab sib zog ntawm sab hauv.

Sab nraud Vuam: Sab nraum cov yeeb nkab tseem muab welded siv tandem ntau cov tshuab dej hlau ntau hom arc vuam. Cov kauj ruam no yog qhov tseem ceeb heev rau kev ua tiav cov weld siab zoo ntawm sab nrauv ntawm cov yeeb nkab.

Ultrasonic kuaj: Sab hauv sab hauv thiab sab nraud, nrog rau cov khoom siv hauv paus ntawm ob sab ntawm Weld, tau tshuaj xyuas siv kev kuaj ultrasonic los kuaj xyuas cov tsis xws luag.

X-ray soj ntsuam: X-Ray Industrial Industrial Kev Tshuaj Ntsuam Xyuas yog ua rau sab hauv thiab sab nraud uas siv cov duab ua kom paub tseeb tias kev pom zoo thiab ua tau zoo.

Kev loj hlob: Cov yeeb nkab tau nthuav dav txhawm rau txhim kho nws txoj kev raug cai thiab kom txhawb kev faib cov yeeb nkab. Kauj ruam no pab ua kom koj cov yeeb nkab ua tau raws li cov lus qhia tshwj xeeb.

Kev Kuaj Hydraulic: Cov kav dej txuas tau raug sim siv cov ntsuas hydraulic kom ntseeg tau tias lawv ntsib tus qauv siab. Lub tshuab kuaj uas feem ntau muaj cov ntaub ntawv tsis siv neeg muaj cov peev txheej thiab cov peev txheej cia.

Chamfering: Qhov xaus ntawm cov yeeb nkab yog chamfered kom ua tiav qhov uas yuav tsum tau bevel loj. Kauj ruam no yog qhov tseem ceeb rau kev npaj cov yeeb nkab rau kev ua ntxiv lossis kev teeb tsa.

Cov txheej txheem LSAW tau paub txog nws txoj kev ua tau zoo thiab muaj peev xwm tsim cov kav dej uas muaj zog thiab lub zog ua kom haum rau cov ntaub ntawv xws li cov roj thiab roj pipelines.
