Cov txheej txheem ntau lawm ntawm txoj kab uas hla loj ncaj seam welded yeeb nkab

1. Plate nrhiav tau: Tom qab cov hlau daim hlau siv los tsim cov loj-inch submerged arc welded ncaj seam steel kav nkag mus rau cov kab ntau lawm, lawv yog thawj zaug rau tag nrho-phaj ultrasonic tshuaj xyuas.
2. Ntug milling: Siv lub tshuab ntug milling los ua ob sab milling ntawm ob sab ntawm cov phaj steel kom ua tiav cov phaj dav, phaj ntug sib luag thiab bevel puab.
3. Pre-bending ntug: Siv lub tshuab ua ntej khoov los ua ntej khoov ntug ntawm lub rooj tsavxwm kom lub ntug ntawm lub rooj tsavxwm muaj qhov curvature raws li qhov yuav tsum tau ua.
4. Kev sib sau: Ntawm JCO txoj kev tshuab, thawj ib nrab ntawm cov phaj pre-bent steel yog stamped rau hauv "J" zoo los ntawm ntau cov kauj ruam, thiab tom qab ntawd ib nrab ntawm cov hlau phaj zoo sib xws yog khoov rau hauv "C" duab, thiab thaum kawg qhov qhib yog tsim. "O" shape.
5. Pre-welding: Cov txheej txheem ncaj seam welded steel kav tau koom ua ke thiab txuas ntxiv welded siv roj shielded vuam (MAG).
6. Internal welding: Siv longitudinal multi-wire submerged arc welding (txog plaub lub xov hlau) los txuas rau sab hauv ntawm cov yeeb nkab ncaj seam steel.
7. Sab nraud vuam: tandem multi-wire submerged arc vuam yog siv los welding sab nraud ntawm longitudinal submerged arc welded steel yeeb nkab.
8. Ultrasonic soj ntsuam I: 100% kev soj ntsuam ntawm lub puab thiab sab welds ntawm lub ncaj seam welded steel yeeb nkab thiab lub hauv paus hlau ntawm ob sab ntawm lub welds.
9. X-ray tshuaj ntsuam I: Ua 100% X-ray industrial TV soj ntsuam ntawm sab hauv thiab sab nraud welds, thiab siv cov duab ua cov txheej txheem los xyuas kom meej qhov rhiab heev ntawm qhov tsis zoo.
10. Txoj kab uas hla nthuav dav: Tag nrho qhov ntev ntawm lub submerged arc welded ncaj seam steel yeeb nkab yog nthuav los txhim kho qhov tseeb qhov tseeb ntawm cov yeeb nkab steel thiab txhim kho kev faib cov kev ntxhov siab hauv cov yeeb nkab steel.
11. Hydraulic siab test: Cov kav hlau txuas tau raug tshuaj xyuas ib qho los ntawm ib qho ntawm lub tshuab ntsuas hydraulic kom ntseeg tau tias cov kav hlau steel ua tau raws li qhov kev ntsuas siab xav tau los ntawm tus qauv. Lub tshuab muaj cov ntaub ntawv tsis siv neeg thiab khaws cia ua haujlwm.
12. Chamfering: txheej txheem cov yeeb nkab kawg ntawm cov yeeb nkab steel uas tau dhau qhov kev tshuaj xyuas kom ua tiav cov yeeb nkab kawg bevel loj.
13. Ultrasonic tshuaj xyuas II: Ua ultrasonic tshuaj xyuas ib qho los ntawm ib qho ntxiv los kuaj xyuas qhov tsis xws luag uas yuav tshwm sim tom qab txoj kab uas hla expansion thiab hydraulic siab ntawm ncaj seam welded steel kav.
14. X-ray tshuaj ntsuam II: X-ray industrial TV tshuaj xyuas thiab cov yeeb nkab kawg weld photography yog ua nyob rau hauv cov yeeb nkab steel tom qab txoj kab uas hla expansion thiab hydraulic siab test.
15. Kev tshuaj xyuas cov khoom sib nqus ntawm cov yeeb nkab kawg: Qhov kev tshuaj xyuas no yog ua los xyuas cov yeeb nkab kawg tsis xws luag.
16. Anti-corrosion thiab txheej: Tsim nyog cov kav dej steel yuav tiv thaiv corrosion thiab coated raws li tus neeg siv yuav tsum tau ua.
