Technical Requirements
- Inner container: made of austenitic stainless steel S30408, fully welded structure, is the core component of the single containment storage tank.
- The storage tank contains a pressure protection system. When the pressure in the storage tank exceeds the setting value, the vent regulating valve will be automatically opened; when the pressure continues to rise, the breathing valve exhales; if the pressure continues to rise, the bursting disc bursts to release the pressure in the tank.
- Inner and outer tank pipelines: the inlet and outlet pipelines for liquid nitrogen and low temperature gaseous nitrogen made of stainless steel (S30408). Pipes and various low temperature and normal temperature valves and instruments form a complete operation area.
