How to install a cryogenic storage tank to enhance the stability of the stand

Cryogenic storage tank is one of the containers in chemical equipment. The safe use of cryogenic storage tank can ensure the safety of chemical production. cryogenic storage tanks (such as LNG storage tanks, liquid argon storage tanks) are a common industrial equipment for storing cryogenic liquids, and play an important role in many industrial fields.

The support structure between the inner tank and the outer shell of the cryogenic storage tank adopts an upper stainless steel strap with a lower stainless steel tube support method. Under normal standing position of the equipment, the gravity load of the liner and its storage medium is transmitted to the shell through 3 stainless steel pipes, and then to the shell legs and the equipment foundation to avoid generating extra eccentric moment load. This structure also guarantees the equipment The need for free contraction of the liner during cryogenic work.

In addition to the structural support of the cryogenic storage tank, there are also requirements for the installation of the cryogenic storage tank. The stability of the stand is the basis for the use of the cryogenic storage tank. The steel structure of the cryogenic storage tank roof shall be carried out after the erection of the temporary support frame on the tank roof. The steel structure center ring of the tank roof shall be prefabricated and inspected on the ground. After confirming that it is qualified, it shall be installed on the center column and the installation position of each steel structure skeleton shall be marked on the center ring. In order to enhance the stability of the platform, two cranes should be used for the symmetrical installation of the steel structure grouping. A positioning line should be drawn on the wall to control the installation position of the steel structure on the tank roof. There is no need for a positioning plate when installing the connecting ring beams of each group of steel structure child bones, and the gap can be directly installed on the main bones and child bones. Welding of steel structures shall be carried out by means of separate group welding. Install the sub-bone between the welded steel structures. At this time, a positioning plate with a gap of 1-2 mm is used to install the ring beams between the steel structures.

The above are the matters needing attention in the process of installing cryogenic storage tanks summarized by the cryogenic storage tank manufacturers. I hope it will be helpful to everyone.
