Muab ob npaug rau sab submerged arc vuam kauv steel yeeb nkab txheej txheem: steel phaj rau hauv cov kab ntau lawm, thawj zaug tag nrho-phaj ultrasonic tshuaj xyuas; 1. Milling: milling tshuab los ntawm ob npoo ntawm steel phaj ntawm ob sab ntawm lub tshuab milling, thiaj li ua tau raws li qhov yuav tsum tau muaj dav, ntug parallelism thiab bevel puab;
2. Pre-bending: kev siv lub tshuab ua ntej khoov rau kev khoov ntawm lub phaj ntug, kom lub ntug ntawm lub phaj muaj qhov curvature kom tau raws li qhov yuav tsum tau ua ntawm curvature;
3. Kev sib sau: JCO molding tshuab nyob rau hauv thawj ib nrab ntawm lub pre-bent steel phaj los ntawm ib tug xov tooj ntawm cov kauj ruam stamping, ces lwm ib nrab ntawm cov hlau phaj kuj bent, nias rau hauv lub "C" zoo, thiab thaum kawg tsim ib tug qhib. "C" puab. Ib nrab ntawm cov hlau phaj los ntawm ntau cov kauj ruam stamping, nias rau hauv "J" zoo, thiab tom qab ntawd ib nrab ntawm cov hlau phaj tseem khoov, nias rau hauv "C" duab, thiab thaum kawg tsim qhov qhib ntawm "O. "zoo li
4. pre-welding: tom qab molding cov yeeb nkab steel seam thiab roj shielded arc vuam (MAG) rau nruam vuam;
5. Internal welding: siv longitudinal multi-wire submerged arc vuam nyob rau hauv sab hauv ntawm lub ncaj seam steel yeeb nkab rau vuam; welding sab nraud: siv longitudinal multi-wire submerged arc vuam nyob rau hauv lub kauv submerged arc vuam vuam nyob rau sab nraud ntawm cov yeeb nkab steel;
6. Ultrasonic tshuaj xyuas Ⅰ: 100% kev tshuaj xyuas ntawm kauv steel yeeb nkab sab hauv thiab sab nraud welds thiab welds ntawm ob sab ntawm cov khoom siv hauv paus;
7. X-ray tshuaj xyuas Ⅰ: 100% ntawm cov welds sab hauv thiab sab nraud X-ray industrial TV tshuaj xyuas, siv cov duab ua haujlwm los xyuas kom meej qhov rhiab heev ntawm qhov tsis pom kev;
8. Kev nthuav dav: tag nrho ntev ntawm cov yeeb nkab ncaj nraim rau kev nthuav dav ntawm cov yeeb nkab steel txhawm rau txhim kho qhov tseeb ntawm cov yeeb nkab steel, thiab txhawm rau txhim kho kev faib tawm ntawm cov kev ntxhov siab hauv cov yeeb nkab steel.
9. Hydrostatic xeem: nyob rau hauv lub tshuab kuaj hydrostatic ntawm cov hlau yeeb nkab txuas hauv paus los ntawm kev tshuaj xyuas hauv paus los xyuas kom meej tias cov yeeb nkab steel kom ua tau raws li cov qauv kev xav tau ntawm kev ntsuas siab, lub tshuab muaj cov ntaub ntawv tsis siv neeg thiab khaws cia;
10. chamfering: kev soj ntsuam ntawm tsim nyog steel yeeb nkab yeeb nkab kawg ua, kom ua tiav qhov yuav tsum tau loj ntawm qhov kawg ntawm cov yeeb nkab bevel;
11. Kev tshuaj xyuas ultrasonic Ⅱ: ib zaug hauv paus los ntawm cov hauv paus ultrasonic tshuaj xyuas los xyuas qhov ncaj seam welded steel yeeb nkab nyob rau hauv txoj kab uas hla, hydraulic siab, tej zaum yuav tsim tsis xws luag;
12. X-ray tshuaj xyuas Ⅱ: X-ray industrial TV tshuaj xyuas thiab lub raj kawg weld filming ntawm steel yeeb nkab tom qab expansion thiab hydrostatic test;
13. Kev tshuaj xyuas cov yeeb nkab kawg sib nqus: qhov kev tshuaj xyuas no yog ua kom pom qhov tsis xws ntawm cov yeeb nkab kawg;
14. Anti-corrosion thiab txheej: tsim nyog steel yeeb nkab raws li tus neeg siv cov kev cai ntawm anticorrosion thiab txheej. Ntxiv nrog rau cov khoom soj ntsuam saum toj no, raws li API tus qauv thiab lwm yam qauv muaj feem xyuam thiab qee cov neeg siv cov kev xav tau tshwj xeeb, nws tseem yuav tsum tau ua qhov kev soj ntsuam kev puas tsuaj thiab lwm yam kev tshuaj xyuas ntawm cov hlau phaj thiab cov kav hlau, nrog rau cov qauv ntawm lub cev thiab tshuaj. Cov khoom ntawm cov khoom siv raw khoom, thiab 100% zoo li kev tshuaj xyuas ntawm cov hlau phaj.
