Boenjiniere bo Hlollang ba phaephe e koetsoeng ka vacuum

Vacuum insulated pipe(VIP), eo hape e tsejoang e le vacuum jacketed pipe (VJP), e sebelisa annulus e phahameng ea vacuum (10⁻⁶ Torr) pakeng tsa likarolo tsa tšepe e sa hloekang ho finyella mocheso o haufi le lefela. Meahong ea LNG, lits'ebetso tsena li fokotsa litefiso tsa letsatsi le letsatsi tsa ho belisoa ho ea ka tlase ho 0.08%, ha li bapisoa le 0.15% bakeng sa liphaephe tse tloaelehileng tse kentsoeng lekobo. Mohlala, projeke ea Chevron's Gorgon LNG naheng ea Australia e sebelisa phala ea 18 km ea vacuum jacket ho boloka mocheso oa -162°C ho pholletsa le sebaka sa eona sa ho romela thepa e kantle ho naha, e fokotsa tahlehelo ea selemo le selemo ea matla ka $6.2 milione.
