1. Plate nrhiav tau: tom qab cov hlau phaj siv los tsim cov loj-inch submerged arc welded ncaj seam steel yeeb nkab nkag mus rau cov kab ntau lawm, thawj zaug ua tag nrho phaj ultrasonic tshuaj xyuas;

2. Ntug milling: ob lub npoo ntawm lub phaj steel yog milled ntawm ob sab los ntawm ntug milling tshuab kom ua tiav qhov yuav tsum tau phaj dav, phaj ntug parallelism thiab groove puab;

3. Pre bending: siv lub tshuab ua ntej khoov ua ntej khoov lub phaj ntug, kom lub phaj ntug muaj qhov yuav tsum tau curvature;

4. Kev sib sau: ntawm JCO txoj kev tshuab, thawj zaug nias ib nrab ntawm lub pre bent steel phaj rau hauv "J" zoo los ntawm ntau kauj ruam stamping, tom qab ntawd khoov ib nrab ntawm cov hlau phaj rau hauv "C" zoo, thiab thaum kawg tsim ib qho qhib "O" duab

5. Ua ntej welding: ua cov qauv ncaj seam welded steel yeeb nkab sib txuas thiab siv roj shielded vuam (MAG) rau txuas txuas ntxiv;

6. Internal welding: longitudinal multi hlau submerged arc vuam (txog plaub hlau) yog siv los welding nyob rau hauv ncaj seam steel yeeb nkab;

7. Sab nraud welding: longitudinal multi hlau submerged arc vuam yog siv los welding sab nraud ntawm longitudinal submerged arc welded steel yeeb nkab;

8. Ultrasonic soj ntsuam I: 100% ntawm cov welds sab hauv thiab sab nraud ntawm cov ncaj welded steel yeeb nkab thiab lub hauv paus hlau ntawm ob sab ntawm lub vuam;

9. X-ray tshuaj ntsuam I: 100% X-ray industrial TV soj ntsuam yuav tsum tau ua rau sab hauv thiab sab nraud welds, thiab cov duab ua cov txheej txheem yuav tsum tau saws los xyuas kom meej qhov rhiab heev ntawm qhov tsis pom kev;

10. Txoj kab uas hla: nthuav dav tag nrho ntev ntawm submerged arc welded ncaj seam steel yeeb nkab los txhim kho qhov tseeb qhov tseeb ntawm cov yeeb nkab steel thiab txhim kho kev faib tawm ntawm kev ntxhov siab hauv cov yeeb nkab steel;

11. Hydrostatic test: tshawb xyuas cov kav hlau txuas ntxiv ib los ntawm ib qho ntawm lub tshuab ntsuas hydrostatic kom ntseeg tau tias cov kav hlau hlau ua tau raws li qhov kev sim siab xav tau los ntawm tus qauv.Lub tshuab muaj kev ua haujlwm ntawm kev kaw lus tsis siv neeg thiab khaws cia;

12. Chamfering: txheej txheem cov yeeb nkab kawg ntawm cov yeeb nkab hlau tsim nyog kom tau raws li qhov xav tau qhov zawj qhov loj ntawm cov yeeb nkab kawg;

13. Ultrasonic tshuaj xyuas II: nqa tawm kev tshuaj xyuas ultrasonic ib los ntawm ib qho ntxiv los xyuas qhov tsis xws luag ntawm longitudinal welded steel kav tom qab txoj kab uas hla expansion thiab dej siab;

14. X-ray tshuaj ntsuam II: X-ray industrial TV tshuaj xyuas thiab yeeb nkab kawg vuam yuav tsum tau nqa tawm rau cov kav hlau tom qab txoj kab uas hla expansion thiab hydrostatic test;

15. Magnetic particle soj ntsuam ntawm cov yeeb nkab kawg: ua qhov kev tshuaj xyuas no kom pom cov yeeb nkab kawg;

16. Kev tiv thaiv corrosion thiab txheej txheej: cov yeeb nkab steel uas tsim nyog yuav tsum muaj kev tiv thaiv corrosion thiab txheej txheej raws li tus neeg siv yuav tsum tau ua.
