Maintenance precautions for pressure vessels

The liquid nitrogen storage tank is a double-layer fixed vacuum powder insulated storage tank. The inner tank is made of stainless steel, and the outer tank is made of Q235B or Q345R.

Infrared thermal imaging-based monitoring method can be used for intelligent monitoring of leakage defects in key facilities of LNG receiving station.

Liquid nitrogen is usually stored at low pressure, but the tank needs to be able to withstand a certain internal pressure. The design pressure is usually around 0.1 MPa (1 bar), but the specific value depends on the actual application and safety requirements.

Liquid nitrogen storage tanks use vacuum insulation technology to effectively isolate heat transfer by creating a high vacuum layer between the inner and outer tanks.

Liquefied gas storage tanks have the following main functions: buffering, cooling, water removal and energy storage.

The thermal insulation design of liquid nitrogen storage tanks is a key factor in ensuring efficient and economical operation of liquid nitrogen storage tanks. Excellent thermal insulation properties can minimize the evaporation and loss of liquid nitrogen.

liquid nitrogen storage tanks are large in size and capacity, which can meet the storage needs of a large number of biological materials.

The working principle of liquid nitrogen storage tank is to liquefy nitrogen and store it in the inner tank.

The working principle of cryogenic storage tank.

This tank piping system design, valves and piping structure is compact, easy to operate, reliable.

Liquid nitrogen storage tanks are meticulously engineered to provide an unparalleled environment for the long-term preservation of delicate biological materials.

There are some key principles that must be understood when storing liquid nitrogen.
