Ngomhlaka-31 Disemba 2021, ipuleti lensimbi le-9Ni lensimbi elishisa kakhulu lamathangi okugcina igesi yemvelo e-LNG (elicwengekile) akhiqizwe yi-Hyundai Steel ladlula isitifiketi sokuhlolwa kwekhwalithi se-KOGAS (Korea Natural Gas Corporation). Ubukhulu bepuleti lensimbi le-9Ni bungu-6 mm kuya ku-45 mm, kanti ububanzi obukhulu bungu-4.5 metres, okwamanje okubanzi kakhulu emhlabeni. Ukuvunyelwa kwalesi sitifiketi kuthuthukisa kakhulu ukuncintisana kwemakethe ye-Hyundai Steel eNingizimu Korea.
Kubikwa ukuthi ukuze kuphasiswe lesi sitifiketi, umkhiqizi we-Hyundai Steel kanye nezinto zokushisela i-Hyundai General Metal Co., Ltd. ubambisene ukuze kufezwe ukutholakala kwazo zonke izinto zokushisela endaweni yazo. I-Hyundai Steel ithe ukutholakala kwezinto zokushisela endaweni yazo kungonga cishe u-30% wezindleko uma kuqhathaniswa nokusetshenziswa kwezinto ezingeniswa kwamanye amazwe.
Ipuleti elijiyile lensimbi engu-9Ni liwumkhiqizo wepuleti elijiyile elisebenza kahle kakhulu elisetshenziselwa ukuqinisekisa ukuphepha kwamatangi okugcina i-LNG asemanzini nasemhlabeni. Izici zalo eziyinhloko okuqukethwe okuphezulu kwe-nickel kanye nobumsulwa obuphezulu. Ligcina amandla aphezulu kanye nokuqina okuhle kakhulu komthelela, lingenye yezinto eziyinhloko ezisetshenziswa ukukhiqiza amathangi amakhulu okugcina i-LNG.
