Scope

This Part of GB/T 18442 specifies the basic requirements, such as material re-
inspection, machining and forming, welding, nondestructive testing, cleaning,
assembly, mark and identification, and exit-factory data, in the fabrication of
static vacuum insulated cryogenic pressure vessels (hereinafter referred to as
cryogenic vessels).
This Part applies to cryogenic vessels, which simultaneously meet the following
conditions:
a) The working pressure of the inner vessel is not less than 0.1 MPa;
b) The geometric volume is not less than 1 m3;
c) The insulation method is vacuum powder insulation, vacuum composite
insulation, or high vacuum multilayer insulation;
d) The storage medium is a refrigerated liquefied gas with a standard boiling
point of not lower than -196 °C.
This Part does not apply to cryogenic vessels in the following scope:
a) The material of inner vessel and outer jacket is non-ferrous metal or non-
metal;
b) HAVE a spherical structure;
c) Stacked insulation;
d) Mobile;
e) STORE refrigerated liquefied gas medium with standard boiling point
below -196 °C;
f) The storage medium is toxic gas according to GB 12268;
g) Those with special requirements such as national defense and military
equipment.
