Kev taw qhia txog kev qhia txog kev siv stainless hlau core corrosion pile vuam.
Cov txheej txheem vuam siv vuam siv vuam los hloov kho qhov chaw ntawm lub workpiece kom ua tau raws li qhov yuav tsum tau ua ntawm lub workpiece thaum ua haujlwm.Cov hlua welding hlau melting efficiency yog siab, qhov seem yog ib qho yooj yim, lub splashing yog me me, lub vuam ib puag ncig yog zoo nkauj, thiab nws muaj peev xwm ua tiav kev nruam thiab ruaj khov vuam rau ntev, uas tuaj yeem txhim kho kev ua haujlwm zoo.
JINGLEI pawg welding tub ntxhais vuam hlau
Hydrogenation reactor feem ntau siv CR-MO steel ua cov khoom siv substrate, thiab stainless hlau tub ntxhais vuam hlau khoom GFS-309L (txheej txheej) thiab GFS-347L (corrosion resistance) yog siv rau sab hauv phab ntsa thiab nto ntawm lub reactor.
GFS-309L + GFS-347L ua ke pawg vuam
● Pidium vuam txheej txheem
Kauj ruam ①:
Ua ntej, GFS-309L yog piled rau ntawm cov khoom siv substrate raws li cov txheej txheem hloov mus ua lub luag haujlwm cushioning, uas tuaj yeem txo qhov muaj peev xwm ntawm cov vuam txuas ntxiv tom ntej.
Kauj ruam ②:
Ob txheej ntawm GFS-347L ntawm pawg welding yog siv los ua cov txheej txheem corrosion, thiab tag nrho cov tuab ntawm cov txheej txheem hloov + txheej txheej yog li 7 ~ 8 hli.
Kauj ruam ③:
Tom qab vuam thermal kho (PWHT), cov neeg siv khoom hauv qab no xav tau 665 ° C × 12H + 705 ℃ × 32h ua piv txwv.
Kauj ruam ④:
Machined lub vuam tshuab mus rau qhov yuav tsum tau thickness.
