The storage tank is a double-cylinder vacuum powder-insulated cryogenic liquid container. The inner container is made of austenitic stainless steel plate (S30408), the head is a standard elliptical head, and the outer container is made of Q345R steel plate. The interlayer is filled with pearl sand and evacuated to the specified technical indicators. At the same time, an adsorbent that can extend the vacuum life is provided.

 

 The theoretical calculation of the evaporation rate index is higher than the standard requirement. The reliability of the equipment strength and the minimum heat leakage of the equipment are ensured, and the equipment has high reliability and advancement.



 The vacuum filtering device of the equipment adopts a skeleton structure with the largest diffusion surface, and the longest possible vacuum filtering pipeline is embedded in the sandwich insulator-pearl sand that needs to be vacuumed, to ensure the complete extraction of the sandwich air and the longevity of the vacuum. The guarantee of the number of years is effectively guaranteed in terms of design and craftsmanship.

 

 The surface of the outer tank has undergone a thorough shot blasting and rust removal treatment to reach the Sa21/2 level standard. The paint is imported paint to ensure that the paint does not deteriorate in at least two years.


  Cryogenic pipelines are specially designed according to the needs of cryogenic liquid storage tanks, and they are led out from the lower end to facilitate system piping layout, operation and control, and special transition structures are adopted at the outlets to meet low temperature requirements and reduce pipeline thermal expansion and contraction. The stress caused to ensure the safety of the storage tank.



  A special vacuum device is used on the cryogenic liquid storage tank, equipped with imported vacuum gauges and vacuum isolation valves, to ensure fast, reliable, and thorough vacuum pumping, and accurate vacuum measurement;



  The storage tank can be filled with liquid at the bottom or top, which is convenient for the design and combination of various technological processes for users.
