How to use Cryogenic liquid gas cylinder?

#Cryogenic liquid gas #cylinder are super vacuum insulated stainless steel pressure vessels designed for the storage, transport and use of liquid #oxygen, liquid #nitrogen, liquid #argon or carbon dioxide, liquefied natural gas, for the safe and economical transport of #cryogenic #liquid #gases, and for on-site storage and supply of liquefied gases.

The construction of the #Portable liquid gas cylinder

The upper part has a protective ring and a pipeline valve system. The central body has a stainless steel shell and a layer of thermal insulation. Inside there is a stainless steel liner and a vacuum layer.

Use of Portable liquid gas cylinder

Liquid supply and use of #PortableLiquidGasCylinder: First, make sure that the main valve of the pipeline of the spare bottle group is closed, open the gas valve and liquid outlet valve on the steel cylinder to be used, then open the corresponding valve on the header skid of the bottle group connected to the steel cylinder, and then open the corresponding main valve of the pipeline. Finally, open the valve at the inlet of the evaporator and the liquid will be evaporated by the evaporator and delivered to the user after being regulated by the pressure regulator. When supplying liquid, if the pressure of the steel cylinder is not sufficient, you can open the booster valve of the steel cylinder and pressurise the steel cylinder through the booster system of the steel cylinder to obtain sufficient liquid supply pressure.

Advantages of Welded insulated cylinder

The first is that it can hold large quantities of gas at relatively low pressures compared to pressurised gas cylinders.

The second is that it provides an easily manipulated cryogenic liquid source. Due to the strength and reliability of the Dewar bottle, its long storage time and its own gas supply system using its built-in evaporator and continuous output of room temperature gases (oxygen, nitrogen, argon) with a flow rate of up to 9Nm3/h, the maximum constant output pressure of the gas can reach 1.2Mpa (medium pressure type) 2.2Mpa (high pressure type), which fully meets the gas consumption requirements under normal circumstances.

Gas supply operation

>>>Preparation

1. There should be a safe distance between the #Dewar flask and the oxygen cylinder (the distance between the two gas cylinder should be more than 5 metres).

2. There should be no naked flame around the cylinder and can, and a fire prevention device should be installed nearby.

3. Check that the Dewar (#tank) is well connected to the end user.

4. Check that all valves, manometers, safety valves and Dewar (tank) valve fittings in the test system are complete and easy to use.

5. The gas supply system must be free of grease and leaks.

Operating Procedures

In order for the Dewar #bottle (tank) gas supply system to provide a continuous, stable, safe and economical gas supply, when using the Dewar bottle (tank) gas supply system, a single Dewar bottle (tank) can be used to supply gas to the terminal. It can also be switched alternately between two or more Dewar bottles (cans) via the busbar.
