HEZE BOILER FACTORY CO.,LTD is the professional manufacturer for lpg tank, cryogenic vacuum
powder insulated storage tank, mainly including cryogenic liquid
CO2 Tank,liquid Oxygen Tank,liquid Argon Tank,liquid nitrogen
tank,LNG Tank with different capacity from 5m3 to 150m3.
liquid CO2 tank to serve for the welding machines
Carbon dioxide storage tank, low temperature liquid carbon dioxide
storage tank, the structure of LCO2 tank is composed of double
containers inside and outside the container, vacuum powder
adiabatic type, can be divided into two types of vertical and
horizontal, the inner material 16MnDR, the outer container material
according to the user area Select Q235-B or Q345, inside and
outside the container sandwich filled with insulating material
pearl sand and vacuum.
Safety technology features
Cryogenic liquid carbon dioxide storage tank with "combination,
safety system valve" using two sets of safety valve at the same
time, in the safety valve periodic check can be closed side, the
other side to continue to work to ensure the safe operation of the
The upper part of the tank is equipped with a pressure gauge,
differential pressure level gauge and liquid level table, you can
always grasp the internal storage capacity and pressure changes,
easy to fill and discharge operation.
The bottom of the tank is equipped with a special tank vacuum
detection, vacuum regulation and vacuum valve can be regularly or
at any time with a vacuum gauge to detect the sandwich vacuum to
ensure the safe operation of the tank.

Inspection, test and acceptance of Cryogenic Storage Tank
1.After inspection of inner cylinder material to make sure it is
qualified, and then put into use.
2.Check all weld joint according to GB150.1～150.4-2011 standard,
after inspection passed, A and B type weld joint need 100% ray
test, C and D type weld joint 100% dye test and issue the test
3.After installation of the shell, there will be a test according
to GB150.1～150.4-2011 standard for checking of geometric dimension,
nozzle orientation and shape deviation.
4.Inspection after pressure test and pressure test report issued,
after pressure test of pumping air into vacuum state, after vacuum
degree requirements helium leak test.
5.After interlayer leak detection qualified fill perlite in vacuum,
vacuum degree meet the requirements of GB/T18442-2011 standard then
sealed-off vacuum degree.
6.After tank manufacturing has been completed, the seller notify
the buyer to the seller's site for pre-acceptance, acceptance of
the project including tank vacuum degree index, the valve
instrument configuration, exterior paint quality, whether the
factory documents is complete, after the acceptance of the buyer,
the seller can deliver goods after signed by both sides.
