Fixed pressure vessels made of austenitic stainless steel with a design temperature of not lower than -196°C shall be constructed in accordance with the GB150 standard. If a vacuum-insulated structure is used, it should be referred to as a \"vacuum-insulated cryogenic pressure vessel\". The construction standards for such vessels are specified in GB/T18442.1~18442.6-2011 \"Fixed vacuum-insulated cryogenic pressure vessels\", and they remain within the scope of application of GB150, meeting the basic safety requirements set out in GB150. GB/T18442 also sets forth specific requirements regarding low-temperature performance and insulation characteristics for this particular structural design; such containers do not need to be constructed in accordance with Appendix E of GB150.3.
