Xav txog, ib pliag, cov ntawv thov tseem ceeb uas xav tau qhov kub thiab txias tsis tshua muaj siab. Cov kws tshawb fawb tau ua tib zoo tswj xyuas cov hlwb, uas tuaj yeem cawm tau txoj sia. Lub foob pob hluav taws tso rau hauv qhov chaw, tsav los ntawm cov roj txias dua li cov uas pom hauv ntiaj teb. Cov nkoj loj thauj cov roj liquefied natural gas thoob plaws ntiaj teb. Dab tsi txhawb nqa cov haujlwm no? Kev tshawb fawb txog kev tsim kho tshiab ua lub luag haujlwm, tseem yog qhov tseem ceebVacuum Insulated Pipes(VIPs) thiab cov neeg txawj ntse uas txuas lawv.

Cov degree ntawm engineering xav tau rau kev nyab xeeb ntawm cov ntaub ntawv cryogenic yog yooj yim underestimated.Vacuum Insulated Pipessawv cev rau ib qho kev sib txuas ntawm lub xeev-of-the-art technology thiab tib neeg kev txawj ntse. Cov kav dej no yuav tsum tuav qhov kub thiab txias, tiv thaiv lub tshuab nqus tsev, thiab txawm tias muaj cov kua dej txaus ntshai. Peb yuav tsum xav txog tias txawm tias qhov tsis zoo ntawm ib feeb, xws li qhov tsis tshua pom pom los yog qhov cuam tshuam me me, tuaj yeem ua rau muaj teeb meem loj.

Dab tsi yuav tsum tau ua kom tiav qib ntawm precision tsis tu ncua? Muaj ob peb txoj kev welding raws li hauv qab no:

1. Gas Tungsten Arc Welding (GTAW): Xav txog ib tus neeg saib xyuas lub sijhawm sib sau ua ke los yog tus kws phais neeg ua tus txheej txheem ilv. Thaum cov cav tov muab cov kev taw qhia, tus welder kev txawj ntse tseem tseem ceeb heev. Lawv lub qhov muag ntse thiab khov kho kom ntseeg tau cov pob qij txha zoo ntawm cov yeeb nkab sab hauv, uas yog qhov tseem ceeb rau kev thauj cov kua dej cryogenic kom nyab xeeb.

2. Gas Metal Arc Vuam (GMAW): Thaum GTAW ua qhov tseem ceeb ntawm qhov raug, Gas Metal Arc Vuam (GMAW) ua tiav qhov sib npaug ntawm qhov nrawm thiab kev ua haujlwm zoo. Hauv hom mem tes, GMAW yog qhov zoo rau kev tsim lub tsho sab nrauv ntawm aVacuum Insulated Yeeb Nkab, muab kev tiv thaiv thaum tswj qhov project tiav efficiency.

3. Laser Beam Vuam (LBW): Qee lub sij hawm, ib theem ntawm precision tshaj li cov pa vuam yog tsim nyog. Hauv cov xwm txheej zoo li no, cov welders siv Laser Beam Vuam (LBW). Txoj kev no siv lub zog tsom teeb los tsim cov welds nqaim nrog qhov tsim hluav taws xob tsawg.

Muaj cov cuab yeej tsim nyog yog qhov tseem ceeb, tab sis nws tsis yog ib kauj ruam nkaus xwb. Welders ua tau zoo yuav tsum paub txog cov ntaub ntawv tshawb fawb, tiv thaiv kev ua haujlwm roj, thiab kev tswj xyuas qhov ntsuas vuam. Yog li, kev cob qhia thiab kev lees paub cov ntawv pov thawj yog qhov tseem ceeb kom paub tseeb tias lub kaw lus muaj kev nyab xeeb thaum siv cov thev naus laus zis cryogenic.

Tuam txhab uas muag nyiamHL Cryogenicnqis peev rau cov neeg ua haujlwm siab tawv kom ntseeg tau lub neej yav tom ntej zoo rau txhua tus. Los ntawm kev ua tej yam zoo li ntawd, peb tuaj yeem pab tsim qhov chaw nyab xeeb rau cov tiam tom ntej kom xav tsis thoob ntawm cov thev naus laus zis no.
