Longitudinally welded kav yog tam sim no dav siv nyob rau hauv ntau industries. Cia wb mus saib seb lawv tsim khoom li cas.
Kev Tshuaj Xyuas Hlau Phaj: Lub phaj hlau yog thawj zaug rau kev tshuaj xyuas ultrasonic los xyuas kom meej nws txoj kev ncaj ncees ua ntej lub submerged arc vuam txheej txheem rau loj-inch yeeb nkab pob qij txha.
Ntug Milling: Ob lub npoo ntawm cov phaj hlau yog ob sab milled siv lub tshuab milling kom tau raws li qhov yuav tsum tau ua rau phaj dav, ntug sib npaug, thiab cov duab zawj.
Pre-Bending: Lub phaj npoo yog pre-khoov siv lub tshuab ua ntej dabtsi yog khoov kom ua tiav qhov yuav tsum tau curvature.
Kev tsim: Ntawm JCO txoj kev tshuab, ib nrab-khoov hlau phaj yog nias rau hauv "J" zoo los ntawm ntau cov kauj ruam, ua raws li kev khoov ib nrab rau hauv "C" duab, thaum kawg tsim ib qho qhib "O" duab.
Pre-Welding: Kev npaj rau longitudinal welding ntawm cov yeeb nkab yuav tsum txuas roj welding (MAG).
Internal Vuam: Sab hauv ntawm cov yeeb nkab ntev welded yog welded siv cov txheej txheem longitudinal multi-wire submerged arc vuam txheej txheem (tsis pub tshaj plaub xov hlau).
Sab Nrauv Vuam: Longitudinal multi-wire submerged arc vuam kuj yog siv rau sab nraud vuam ntawm cov yeeb nkab.
Ultrasonic Inspection I: 100% kev tshuaj xyuas ntawm cov welds sab hauv thiab sab nraud thiab cov hlau ntawm ob sab ntawm cov welds yog ua los ntawm kev siv tshuab ultrasonic.
X-Ray Inspection I: 100% X-ray tshuaj xyuas nrog lub TV muaj nyob rau hauv thiab sab nraud welds. Ib daim duab cov ntaub ntawv ua kev tswj xyuas qhov system ua kom qhov rhiab heev ntawm kev tshuaj xyuas.
Txoj kab uas hla: Qhov ntev ntawm lub submerged arc welded yeeb nkab tau nthuav dav los txhim kho qhov tseeb qhov tseeb thiab kev ntxhov siab hauv cov yeeb nkab.
Kev Ntsuas Hydrostatic: Txhua cov yeeb nkab txuas tau raug kuaj ib leeg ntawm lub tshuab kuaj hydraulic kom ntseeg tau tias nws ua tau raws li tus qauv ntsuas siab. Lub tshuab muaj cov ntaub ntawv tsis siv neeg thiab khaws cia.
Chamfering: Cov kav dej tshuaj xyuas yog chamfered ntawm qhov kawg kom ua tau raws li qhov xav tau qhov zawj qhov ntev rau cov kav dej sib txuas.
Ultrasonic kuaj xyuas II: Kev tshuaj ntsuam ob zaug tau ua los tshawb xyuas cov tsis xws luag uas yuav tau tshwm sim tom qab cov kev sim ua haujlwm thiab hydrostatic kev sim.
X-Ray Inspection II: X-ray muaj kev tshuaj xyuas yog ua rau ntawm cov yeeb nkab kawg thiab vuam seams tom qab txoj kab uas hla expansion thiab hydrostatic testing.
Sib Nqus Particle Test ntawm Cov Yeeb Nkab Kawg: Qhov kev tshuaj xyuas no yog ua los txheeb xyuas cov teeb meem uas tshwm sim ntawm qhov kawg ntawm cov kav dej.
