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.
Kuxelwe ukuba ukuze uphumelele esi satifikethi, i-Hyundai Steel kunye nomvelisi wezinto zokuwelda i-Hyundai General Metals Co., Ltd. baye baqaphela indawo yazo zonke izinto 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.
