Comparison of ASME VIII DIV low pressure pressure vessel and GB standard design

Ensuring the safe operation of low-temperature storage tanks involves various considerations.

Precautions for using liquid nitrogen storage tanks

The low temperature liquid nitrogen storage tank series is a double-layer vacuum powder adiabatic storage tank for storing liquid oxygen, liquid nitrogen, liquid argon, carbon dioxide and liquefied natural gas.

The capacity of liquid nitrogen storage tanks is usually measured in liters or cubic meters, and the size of the tank is determined according to demand.

Cryogenic tank containers have 22 bar pressure and can transport a wide range of LNG products, including nitrogen, argon, oxygen, CO₂, N20, LNG, and ethylene. Furthermore, our tanks are sturdy and adaptable, providing excellent payload performance and unique solutions.

The current development status and technological advancement of cryogenic storage tanks in different countries are mainly reflected in the continuous optimization and innovation of design, building and construction processes.

Stirage tanks that meet GB and ASME codes have capacities ranging from 5 to 300 m3, and their design pressures can reach 22 bar (PED) or 24 bar (ASME), depending on the needs of the customer. They withstand earthquakes and strong winds thanks to their support legs.

When draining the self-pressurized liquid nitrogen tank, the boosting valve and the inlet/discharge valve are open, and only the vent valve is closed.

Routine maintenance of liquid nitrogen storage tanks.

The self-pressurizing liquid nitrogen tank is different from conventional containers. In addition to liquid nitrogen, it can also be filled with liquid gases such as liquid oxygen and liquid ammonia.

Cycle inspection of cryogenic storage tanks needs to be determined according to the technical conditions of use of storage tanks.

The introduce of liquid argon storage tank.

The cryogenic pipelines are centrally led out from the lower end of the tank, which is convenient for operation and maintenance.

When a fire gets out of control, it is necessary to closely monitor the burning situation of the LNG storage unit and take contingency measures such as emergency evacuation of the hazardous area in a timely manner.

The volume of the storage tank is limited.

Liquid nitrogen storage tanks can store liquid nitrogen at extremely low temperatures (about -196°C), which is suitable for applications that require ultra-low temperature environments, such as biological sample preservation, superconductor cooling, etc.

Multiple layers of materials, including vacuum panels, stainless steel, and aluminum, make up this insulation. By minimizing heat conduction, the vacuum layer ensures effective storage and lowers the possibility of CO2 prematurely changing into a gaseous state.

We use cryogenic liquid nitrogen tank for input and output of liquid, we need to pay attention to what details.

Drawing from industry experience, let’s explore practical insights into the day-to-day operation of low-temperature storage tanks.

This tank piping system design, valves and piping structure is compact, simple and reliable operation.

The container is usually made from high-quality insulating materials like polyurethane foam or vacuum-insulated panels to minimize heat transfer.Commonly made from aluminum or stainless steel due to their durability and ability to withstand low temperatures.

Insulate the pipeline to prevent the equipment from freezing and cracking, when taking external slow warming measures, but prohibit the use of open flame direct baking or heating methods.

It promotes combustion and results in substantially higher flame temperatures than air alone.
