Kwiminyaka yakutshanje, ngokukhula kokuthandwa kwezicelo zetekhnoloji ye-cryogenic, imfuno ye-austenitic stainless steel cryogenic inqanawa iyakhula. Ukuze kuphuculwe amandla emveliso ye-austenitic stainless steel, iteknoloji yokomeleza ubunzima yabakhona. Emva kokwamkela le teknoloji, uxinzelelo oluvumelekileyo lwezinto eziphathekayo luyanda kakhulu, kwaye ubukhulu bodonga lwesitya sangaphakathi buya kuncitshiswa malunga nesiqingatha xa ubukhulu bodonga buchongwa luxinzelelo lwe-tensile, olunciphisa kakhulu ubunzima kunye nokuqonda ukukhanya i-austenitic stainless steel stainless isitya se-cryogenic.

Ukuze kuphuculwe ukukhuphisana kwemveliso, i-NTtank (emva koku ebizwa ngokuba yi "Company") iqalise iprojekthi kwi-teknoloji yokuqinisa i-cryogenic kwi-container ye-cryogenic ukususela ngoJulayi 2022. Emva kokuyilwa kwetanki yesampula yovavanyo, uhlalutyo loxinzelelo lwezibalo zokubala, izinto kunye ne-welding. Ukukhetha izinto, uvavanyo lwenkqubo ye-welding, uvavanyo lwenkqubo yokuwelda kwangaphambili kunye nokuveliswa kwetanki yesampuli, ukuya kumbindi kaSeptemba 2023, inkampani yamema iqela leengcali zeNational Type Certificate Authority - Machinery Industry Shanghai Lanya Petrochemical Equipment Inspection Co., Ltd. ukutyelela isiza ukuze ubone uvavanyo lokuqinisekisa inkqubo yokuqinisa inkqubo yezikhongozeli zesampulu. Okwangoku, uvavanyo lokuqinisekisa inkqubo luphumelele ngempumelelo isatifikethi.

Ukuphumelela ngempumelelo kovavanyo lokuqinisekiswa kwenkqubo kubonisa ukuba inkampani iye yakwazi ukuqinisa iteknoloji yesikhongozeli se-cryogenic. Okulandelayo, itekhnoloji iya kusetyenziswa ukwenza isikhongozeli sokuqala se-vacuum adiabatic cryogenic pressure isitya sesampulu kwaye uphumelele uvavanyo lomgangatho wokusebenza ophantsi. Emva kokufumana isatifikethi sovavanyo lohlobo, inkampani iya kuba nesiqinisekiso sokuvelisa ngobuninzi be-vacuum vacuum ye-adiabatic cryogenic pressure vessels ngokusebenzisa iteknoloji yokomeleza ubunzima.
