Iiflaski zeDewar, ezaziwa ngokuba ziibhotile zeDewar okanye iiflaski zokufunxa,
Unyango lobushushu be-post-weld lujolise ekupheliseni uxinzelelo olushiyekileyo kunye nokuphucula ukuqina kobushushu obuphantsi kwiinqanawa zoxinzelelo.
Umgangatho wemikhumbi yoxinzelelo lobushushu obuphantsi buxhomekeke kakhulu kwizinto ezisetyenzisiweyo, ngokukodwa iintsimbi ezinobushushu obuphantsi.
Ukuwelda kwiindawo ezinobushushu obuphantsi kubangela imingeni ekhethekileyo efuna ubuchule obukhethekileyo kunye nobuchule.
Kwiimeko ezinzima ezineemeko ezibandayo ezigqithisileyo, ukukhethwa kwezinto ezifanelekileyo zobushushu obuphantsi kuba yinto ebalulekileyo ekugcineni isidima sesakhiwo kunye nokusebenza.
Phonononga indima ebalulekileyo yetekhnoloji yokuphola ngokukhawuleza kwitanki zokugcina ubushushu obuphantsi ngeli nqaku.
Umsebenzi kufuneka ulawule ngokungqongqo umgangatho wolwelo kunye noxinzelelo ukuba ungagqithi kwixabiso elikhankanyiweyo, kwaye kwangaxeshanye, umgangatho wolwelo kufuneka uhlolwe ngokuchasene nesiza ukunqanda ukugcwala.
