Product Description
A 20-cubic-meter second-hand cryogenic liquid storage tank, typically used for storing cryogenic liquids such as liquid oxygen, liquid nitrogen, and liquid argon. The following is a detailed description of this product:
I. Basic Specifications
• Volume: 20 cubic meters
• Type: Second-hand cryogenic liquid storage tank
• Structure: Generally, it is a double-layer structure. The inner liner is made of stainless steel, while the outer shell is made of carbon steel or other materials. The interlayer is used for thermal insulation and heat preservation.
II. Thermal Insulation and Heat Preservation
• Insulation method: Powder insulation is often used, such as vacuum powder insulation or atmospheric powder insulation. Vacuum powder insulation has a better effect. By evacuating the space filled with powder, gas heat transfer is reduced, and at the same time, the powder particles weaken radiative heat transfer.
• Insulation material: The interlayer may be filled with expanded perlite (pearl sand) or other materials with low thermal conductivity to reduce heat transfer and maintain a low-temperature environment.
III. Design Features
Safety valves, pressure gauges, liquid level gauges and other safety accessories are installed to ensure the safe operation of the storage tank.
It may be equipped with a vaporizer for facilitating pressurization and filling inside the tank.
There may be rotating spiral stairs, operation platforms and safety guardrails on the exterior of the storage tank, which facilitate operation and maintenance.
IV. Precautions for Use
When the storage tank is in operation, there are potential dangers such as leakage, overpressure and explosion. Therefore, a complete inspection system should be formulated and strictly implemented.
Regularly inspect the vacuum degree, wall thickness, etc. of the storage tank to ensure that the equipment is in good condition.
Avoid placing flammable, explosive items and all kinds of sundries near the storage tank. Smoking and open flames are strictly prohibited.
V. Precautions for Purchasing Second-hand Equipment
When purchasing a second-hand cryogenic liquid storage tank, it is necessary to communicate in detail with the merchant about the condition of the equipment, its service life, maintenance records and other information.
Ensure that the equipment complies with safety standards and has the corresponding qualification certificates and inspection reports.
Negotiate the terms such as price, mode of transportation and after-sales service well to ensure the smooth progress of the transaction.
In conclusion, a 20-cubic-meter second-hand cryogenic liquid storage tank is an important storage and transportation equipment, featuring a double-layer structure, excellent thermal insulation performance, and multiple safety design features. When purchasing and using it, relevant regulations and precautions must be followed to ensure the safe operation of the equipment.
