Nge-31 kaDisemba, i-2021, i-9Ni yentsimbi yentsimbi ye-ultra-low ye-LNG (igesi yendalo engamanzi) eveliswe yi-Hyundai Steel iphumelele isiqinisekiso sokuhlolwa komgangatho we-KOGAS (Korea Natural Gas Corporation).Ubukhulu beplate yensimbi ye-9Ni yi-6 mm ukuya kwi-45 mm, kwaye ububanzi obukhulu buziimitha ezi-4.5, okwangoku bukhulu kakhulu emhlabeni.Ukwamkelwa kwesi satifikethi kuphucula ngakumbi ukhuphiswano lwentengiso yeHyundai Steel eMzantsi Korea.
Kuxelwa ukuba ukuze uphumelele esi satifikethi, iHyundai Steel kunye nomvelisi wezinto zokuwelda iHyundai General Metal Co., Ltd. ibambisene ukuze iqonde indawo yazo zonke izixhobo zokuwelda.I-Hyundai Steel yathi ukugcinwa kwezixhobo ze-welding zasekhaya kunokonga malunga ne-30% yeendleko xa kuthelekiswa nokusetyenziswa kwezixhobo ezivela kumazwe angaphandle.
I-9Ni ipleyiti eshinyeneyo yentsimbi yimveliso yepleyiti etyebileyo esebenza kakhulu kakhulu esetyenziselwa ukuqinisekisa ukhuseleko lwamatanki okugcina e-LNG elwandle nasemhlabeni.Iimpawu zayo eziphambili zinomxholo ophezulu we-nickel kunye nococeko oluphezulu.Ukugcina amandla aphezulu kunye nokuqina kwempembelelo ebalaseleyo, yenye yezinto eziphambili ezisetyenziselwa ukwenza iitanki ezinkulu zokugcina i-LNG.
