1. Dab tsi yog qhov tseem ceeb hauv kev sib tw ua lag luam rau SSAW kav?
Teb:Raws li kev txheeb xyuas kev lag luam, kev sib tw hauv SSAW kev lag luam yog tsav los ntawm:
Kev sib tw hauv kev lag luam vim kev loj hlob qeeb thiab ntau tus players.
Lub zog sib tham ntawm cov neeg yuav khoom (xws li cov tuam txhab roj thiab roj loj).
Lub zog sib cog lus ntawm cov khoom siv raw khoom.
Qhov kev hem thawj ntawm cov neeg sib tw tshiab muaj peev xwm.
Lub siab los ntawm cov khoom siv hloov pauv, xws li LSAW thiab ERW kav-4.
2. Cov kav dej SSAW puas tuaj yeem siv rau cov kav dej sab nraud lossis cov kav dej slurry?
Teb:Feem ntau,tsis muaj. SSAW kav dej tsis pom zoo rau submarine roj thiab roj pipelines los yog thauj slurries xws li thee slurry. Cov kev xav tau ib puag ncig thiab kev pheej hmoo corrosion / yaig ntau dua ua rau lawv tsis haum. LSAW kav yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov tseem ceeb no vim lawv qhov kev ntseeg siab dua-1.
3. Dab tsi yog qhov teeb meem tshwm sim nyob rau hauv cov kav dej siab uas ua los ntawm cov kav dej welded thaum lub sij hawm kuaj xyuas?
Teb:Cov teeb meem tshwm sim hauv thaj chaw muaj xws li:
Misalignment (Wrong Edge):Ib qho teeb meem tshwm sim los ntawm kev sib dhos tsis raug thiab vuam-9.
Internal Weld Defects:Xws li tsis muaj kev nkag mus, tsis muaj fusion, thiab porosity, feem ntau pib los ntawm kev tsim khoom theem-9.
Corrosion / Erosion Thinning:Tshwj xeeb tshaj yog nyob rau hauv pipelines nqa abrasive los yog corrosive media-9.
4. Yuav ua li cas lub ntiaj teb no kev lag luam rau SSAW kav yuav tsum evolve los ntawm 2031?
Teb:Kev lag luam thoob ntiaj teb SSAW yeeb nkab yuav tsum pom kev loj hlob tsis tu ncua los ntawm 2025 txog 2031. Cov cheeb tsam tseem ceeb suav nrog North America, Europe, thiab Tuam Tshoj. Kev ua lag luam muaj kev sib tw nrog cov players loj xws li Welspun, JFE Steel, JSW Steel, thiab Nippon Steel. Covroj thiab roj sectortseem yog thawj daim ntawv thov thaj chaw, ua raws li kev tsim kho thiab tshuaj lom neeg kev lag luam-10.
5. Cov kev taw qhia yav tom ntej yog dab tsi rau kev txhim kho SSAW yeeb nkab zoo?
Teb:Lub neej yav tom ntej yog nyob rau hauv:
Txhim khu kev tswj tau zoo:Kev tswj nruj dua ntawm cov khoom siv raw (steel plates) ntau lawm kom ntseeg tau tias muaj zog thiab toughness-2.
Advanced NDT:Kev siv dav dav ntawm qhov tseeb thiab txhim khu kev qha automated uas tsis yog -cov txheej txheem kuaj kev puas tsuaj, xws li kev sib txuas cov pa ultrasound nrogTOFD, txhawm rau txhim kho qhov ntsuas qhov tsis raug thiab qhov ntsuas qhov tseeb-8.
Kev txhim kho txheej txheem:Kev txhim kho thev naus laus zis tsis tu ncua hauv kev tsim thiab vuam txheej txheem kom kov yeej cov kev txwv tsis pub muaj.
