Safety of liquid oxygen tanks

The filling process of liquid oxygen tanks involves converting oxygen from gas to liquid and storing it safely in the tank. This process requires efficient equipment and strict control systems.

In the medical field, the application of liquid oxygen tanks is crucial. They not only provide an efficient way to store oxygen, but also greatly promote the development of various medical activities.

The purpose of safe distance from liquid oxygen storage containers is to ensure safety.

the design temperature of a liquid oxygen tank is usually set between -190°C and -200°C

Liquid oxygen tanks must take strict safety measures during operation and storage to prevent accidents.

The tank needs to be precooled before filling to avoid overheating when the liquid oxygen comes into contact with the inner wall of the tank.

Before using liquid oxygen storage tanks, a small amount of liquid nitrogen should be put in to pre-cool it.

Storage of liquid oxygen must be insulated, so the liquid oxygen tank has an inner tank, an insulation layer (or vacuum layer), and an outer shell.

The inner liner of liquid oxygen storage tank is made of 16MnDR and the outer liner of liquid oxygen storage tank is made of Q245R or Q345R.The liquid oxygen storage reservoir selects “combination, safety system valve” using two groups of safety valves to work together, in the time calibration of the safety valve can be closed on one side, the other side is still working, to ensure the safe operation of the liquid oxygen storage reservoir.

The stainless steel inner tank is suitable for contact with low-temperature media, and the plate thickness can withstand 8 to 16 kilograms of pressure, which is enough to ensure the pressure-bearing safety of the cryogenic liquid oxygen tanks.

Liquid oxygen tanks convert oxygen into liquid by cooling it below its liquefaction point (about -183°C). A vacuum insulation layer is provided inside the tank to reduce the evaporation loss of liquid oxygen. Liquid oxygen is converted into gaseous oxygen for use when needed through an evaporator.

According to the size, material and design requirements of the tank, select the appropriate welding method, such as tungsten inert gas welding (TIG), metal arc welding (MIG) or electron beam welding.

The maintenance of liquid oxygen tanks includes the maintenance of the outer shell and inner cylinder, the maintenance of the insulation system, the calibration of safety accessories, and the maintenance of the vacuum degree.

The installation site must have good ventilation conditions or ventilation and ventilation devices, and can safely discharge liquids and gases.

Liquid oxygen tanks have different requirements and standards in different application fields such as medical, industrial and aerospace.

The protective equipment and appearance of the liquid oxygen storage tank should be in good condition, and purging and cleaning have been completed

Liquid oxygen storage tanks are used for transportation and storage equipment

The testing of liquid oxygen tanks covers many aspects, including pressure testing, vacuum maintenance testing, chemical and physical testing, welding quality inspection, leak testing, and emergency response drills.

Liquid oxygen tanks have a wide range of applications, covering a number of important areas, each of which makes full use of the characteristics and advantages of liquid oxygen.

The structure of liquid oxygen storage tanks is carefully designed to have sufficient strength and toughness to prevent rupture or leakage under extreme conditions.

Whether during transportation, operation or storage, liquid oxygen tanks must be kept upright and effectively isolated.
