This part of GB/T 18442 specifies the basic requirements for steel plates, forgings, pipes and fittings, insulation materials, adsorbent materials, welding materials, annular space bracing materials and purchased parts of static vacuum insulated cryogenic pressure vessels (hereinafter referred to as "cryogenic vessels").
This part is applicable to cryogenic vessels that simultaneously meet the following conditions:
a) the geometric volume is not less than 0.1MPa;
b) the geometric volume is not less than 1m3;
c) the insulation mode is vacuum powder insulation, vacuum composite insulation or high vacuum multilayer insulation;
d) cryogenic vessel storing refrigerated liquefied gas contents with standard boiling point not lower than -196℃.
This part is not applicable to cryogenic vessels that meet the following conditions:
a) cryogenic vessel with the inner vessel and outer jacket made of non-ferrous metal or non-metallic materials;
b) cryogenic vessel with spherical structure;
c) cryogenic vessel with stacked insulation;
d) transportable cryogenic vessel;
e) cryogenic vessel storing refrigerated liquefied gas contents with standard boiling point lower than -196℃;
f) cryogenic vessel storing toxic gas as specified in GB 12268;
g) cryogenic vessel with special requirements such as national defense military equipment.
