CRYOGENIC STORAGE TANKS
Cryogenic is the term used in physics for production and processes carried out at very low temperatures (-150°C to -273°C). Oxygen (LOX), Argon (LAR) and Nitrogen (LIN) in liquid form are cryogenic liquids. Cryogenic tanks are produced for the transportation and storage of these low temperature industrial gases in liquid form. Cryogenic storage tanks are specially designed to minimize heat transfer and maintain very low temperatures.
Cryogenic tanks have three basic components:
Inner Tank
Inner tank and pipes made of stainless steel to ensure high quality cleaning and with suitable strength properties when exposed to cryogenic temperatures.
Outer Vessel (Jacket)
An outer container made of carbon steel maintains the insulation and vacuum around the inner tank under normal operating conditions. Typically, the outer container is not exposed to cryogenic temperatures.
Insulation
The space between the inner tank and the outer container is filled with perlite, which has the ability to maintain cryogenic temperature, and is subjected to high vacuum treatment. The vacuum and insulating material help reduce heat transfer, thereby reducing boiling of liquid oxygen, liquid nitrogen, or liquid argon stored in the container.
The maximum working pressure of cryogenic liquefied gas storage tanks ranges from 2 to 37 bar, depending on where the tank is to be used. It can be designed vertically or horizontally according to customer demand.
During the manufacturing phase of cryogenic tanks, the tests and inspections required by the standards are carried out by third-party organizations and all tanks are certified and presented to our customers with CE and Pi marks. Our tanks are produced according to PED 97/23/EC and TPED 2010/35/EU regulations and AD Merkblatt Code 2000, EN 13458, EN 13530, EN 13445, EN 12493, ADR 2013 and ASME Sec VIII Div1 standards. Depending on the demand, production is also carried out within the framework of the standards required by different countries.
