Ngomhla wama-31 kuDisemba ngo-2021, ipleyiti yentsimbi ye-9Ni yentsimbi enobushushu obuphantsi kakhulu yeetanki zokugcina i-LNG (igesi yendalo enyibilikisiweyo) eyenziwe yiHyundai Steel yaphumelela isiqinisekiso sokuhlolwa komgangatho seKOGAS (Korea Natural Gas Corporation). Ubukhulu bepleyiti yentsimbi ye-9Ni buyi-6 mm ukuya kwi-45 mm, kwaye ububanzi obukhulu buyi-4.5 yeemitha, okwangoku elona banzi kwihlabathi liphela. Ukuvunywa kwesi siqinisekiso kuphucula ngakumbi ukukhuphisana kwemarike yeHyundai Steel eMzantsi Korea.
Kubikwa ukuba ukuze kuphumelele esi siqinisekiso, iHyundai Steel kunye nomenzi wezinto zokuwelda iHyundai General Metals Co., Ltd. baye baqonda ukuba zonke izinto zokuwelda zibekwe kwindawo yazo. IHyundai Steel ithe ukuwelda kungenziwa endaweni yazo ngexabiso elimalunga ne-30% xa kuthelekiswa nokusetyenziswa kwezinto ezingeniswa kwamanye amazwe.
Ipleyiti etyebileyo yentsimbi ye-9Ni yimveliso yepleyiti etyebileyo esebenza kakhulu esetyenziselwa ukuqinisekisa ukhuseleko lweetanki zokugcina i-LNG zaselwandle nezasemhlabeni. Iimpawu zayo eziphambili kumxholo ophezulu we-nickel kunye nobunyulu obuphezulu. Igcina amandla aphezulu kunye nokuqina okugqwesileyo kwempembelelo, yenye yezona zinto ziphambili ezisetyenziselwa ukwenza iitanki ezinkulu zokugcina i-LNG.
