8bar Pressure Cryogenic Tank 30m3 Liquid Oxygen Tank

8bar pressure cryogenic tank 30m3 liquid oxygen tank 

Powder insulation Low temperature liquid O2 tank made in China

Cryogenic liquid storage tanks is a series of products of producing first, second , third types of pressure vessel ,the products strictly in accordance with the GB150 "pressure vessels", GB18442-2011 stationary vacuum insulation cryogenic pressure vessel, and the fixed safety technical supervision type of pressure vessel to design,

manufacture,inspect and accept.

The cryogenic storage tank is a vertical or horizontal double-layer vacuum insulated storage tank for storing liquid oxygen, nitrogen, argon, carbon dioxide and other media. The inner liner is made of austenitic stainless steel. The outer container is made of Q235-B, Q245R or 345R depending on the user's area. The inner and outer containers are filled with heat-insulating material, pearl sand or aluminum foil, insulation cotton and vacuum, with the advantage of compact structure , low issuance date,small footprint,centralized control, safe,reliable, easy operation and maintenance.

Inspection, Test and Acceptance of Low Temperature 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 report.

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.
