(1) Cov ntaub ntawv raw yog sawb steel coils, vuam hlau, thiab fluxes.Kev tshuaj xyuas lub cev thiab tshuaj nruj yuav tsum tau ua ntej kev nqis peev.
(2) Kev sib koom ua ke ntawm sawb hlau taub hau thiab tus Tsov tus tw, siv ib leeg-xaim lossis ob-xaim submerged arc vuam, tom qab coiling rau hauv cov yeeb nkab steel, tsis siv neeg submerged arc vuam yog siv los kho vuam.
(3) Ua ntej kev tsim, cov sawb tau txais kev sib tw, ntug trimming, ntug kev npaj, deg tu thiab conveying, thiab kho ua ntej khoov.
(4) Lub tshuab hluav taws xob tiv tauj lub ntsuas hluav taws xob yog siv los tswj lub siab ntawm lub tog raj kheej ntawm ob sab ntawm cov khoom siv los xyuas kom meej qhov kev sib tw ntawm cov sawb.
(5) Txais kev tswj sab nraud lossis kev tswj sab hauv yob txoj kev.
(6) Weld gap control device yog siv los xyuas kom meej tias qhov sib txawv weld ua tau raws li qhov yuav tsum tau ua ntawm vuam, thiab cov yeeb nkab txoj kab uas hla, tus nqi ntawm misalignment thiab qhov sib txawv weld yog nruj me ntsis tswj.
(7) Ob leeg vuam sab hauv thiab sab nraud vuam txais yuav American Lincoln hluav taws xob vuam tshuab rau ib-xaim los yog ob-xaim submerged arc vuam, thiaj li kom tau txais kev ruaj khov vuam specifications.
(8) Welds raug tshuaj xyuas los ntawm online txuas ntxiv ultrasonic tsis siv neeg qhov tsis zoo, uas lav 100% tsis muaj kev puas tsuaj rau kev ntsuas ntawm kauv welds.
(9) Siv lub tshuab cua plasma txiav cov yeeb nkab steel rau hauv ib qho.
(10) Tom qab txiav rau hauv ib lub kav hlau, thawj peb cov kav hlau steel ntawm txhua pawg yuav tsum tau ua raws li kev tshuaj xyuas thawj zaug kom ntseeg tau tias cov txheej txheem ua cov yeeb nkab tsim nyog ua ntej muab tso rau hauv kev tsim khoom.
(11) Cov khoom uas txuas ntxiv sonic flaw nrhiav pom ntawm cov welds undergo phau ntawv ultrasonic thiab X-ray rov kuaj xyuas.
(12) Cov kav dej uas cov sawb hlau taub qab vuam seams thiab D-zoo li cov pob qij txha cuam tshuam cov kauv vuam seams yog txhua yam tshuaj xyuas los ntawm X-ray TV lossis ua yeeb yaj kiab.
(13) Txhua cov yeeb nkab steel tau dhau qhov kev sim siab hydrostatic, thiab lub siab siv lub foob radial.Kev ntsuas siab thiab lub sijhawm yog nruj me ntsis tswj los ntawm cov yeeb nkab steel hydraulic microcomputer nrhiav kom tau cov cuab yeej.Cov ntsuas ntsuas tau raug luam tawm thiab kaw.
(14) Cov yeeb nkab kawg machining, kom lub verticality ntawm lub ntsej muag kawg, lub kaum sab xis thiab obtuse ntug yuav raug tswj kom raug.
Kauv seam submerged arc welded steel yeeb nkab (SY5036-83) rau kev thauj mus los ntawm cov kua dej yog tsuas yog siv rau cov kav dej thauj cov roj thiab cov pa roj;kauv seam high-frequency welded steel yeeb nkab (SY5038-83) rau kev thauj mus los ntawm cov kua dej siab, siv cov txheej txheem siab zaus welding txoj kev Welded, kauv seam high-frequency welded steel yeeb nkab rau kev thauj mus los ntawm cov kua dej siab.Cov yeeb nkab steel muaj lub zog siab-cov kabmob muaj peev xwm thiab cov yas zoo, uas yooj yim rau vuam thiab ua haujlwm.Feem ntau, cov spiral seam submerged arc welded steel yeeb nkab (SY5037-83) rau kev thauj mus los uas tsis tshua muaj siab yog tsim los ntawm ob sab tsis siv neeg submerged arc vuam los yog ib sab vuam rau dej, Submerged arc welded steel yeeb nkab rau conveying cov dej tsis tshua muaj siab. xws li roj, cua thiab chav
