Low-temperature storage tank structure:
A low-temperature storage tank is a compact storage unit equipped with various accessories (valves, safety systems, etc.) for storing low-temperature liquids. The tank consists of a carbon steel vacuum shell and a pressure vessel inside it. It can operate under low to medium pressure as per actual design requirements. Blasting discs and double safety valves provide protection against excessive pressure. The safety relief device is designed to protect the internal pressure vessel and vacuum shell, adhering to GB150 and "Fixed Container Regulations." It includes a double safety relief valve and a bursting disc assembly for the internal pressure vessel protection, as well as a bursting cap for the vacuum shell (shell). The tank is designed and manufactured for safety, reliable operation, and durability (can operate without failure for years), and strict adherence to proper safety and operational procedures is required during tank operation.
High safety requirements. As the tank stores low-temperature liquids, in the event of an accident, the refrigerated liquid would volatilize in large quantities, with the vaporization rate being approximately 300 times that of the refrigerated state, forming explosive gas clouds in the atmosphere. Therefore, standards such as API, BS, etc., require tanks to be constructed with double-walled design and employ sealing concepts. In the event of a leak in the first layer, the second layer can completely seal the leaked liquid and evaporated gas, ensuring storage safety.
