Export 30 Cubic Meter LNG Storage Tanks, Manufacturer Supplies 5-150 Cubic Meter LNG Storage Tanks

LNG (Liquefied Natural Gas) is the abbreviation for Liquefied Natural Gas. Natural gas is a combustible gas extracted naturally from gas fields, primarily composed of methane. LNG is produced by cooling the gaseous natural gas under atmospheric pressure to -162°C, causing it to condense into a liquid. After liquefaction, natural gas significantly reduces storage and transportation space and costs, and boasts high calorific value and superior performance.

LNG is a clean and efficient energy source. Importing LNG helps energy-consuming countries achieve energy supply diversification and ensure energy security, while exporting LNG aids natural gas-producing countries in effectively developing their natural gas resources, increasing foreign exchange earnings, and promoting national economic development. Therefore, LNG trade is emerging as a new hot spot in the global energy market.

Overview of Liquid Low-Temperature Storage Tank - LNG Storage Tank

With the rapid development of the national economy and the widespread adoption of low-temperature technology, the application of low-temperature liquids has expanded significantly, including liquid hydrogen, liquid oxygen, liquid nitrogen, liquid argon, liquid helium, and liquefied natural gas. The production, application, and research of low-temperature liquids necessitate their storage and transportation. Many important scientific research projects require operations under low-temperature conditions. The demand for low-temperature storage and transportation containers is continually growing across various industries, particularly in industrial, agricultural, defense research, and medical fields.

Due to the low boiling point and small latent heat of vaporization of low-temperature liquids, a significant cost is incurred to obtain low-temperature liquefied gases. Therefore, the effective storage and transportation of low-temperature liquids hold significant economic value. In the application of low-temperature technology, the following situations often arise:

(1) Centralized production followed by distribution to various users, such as the centralized production and distribution of liquid oxygen, liquid nitrogen, liquid argon, liquefied natural gas, liquefied petroleum gas, and liquid helium.

(2) Products produced for short-term use are intended for longer-term application, such as the case with many testing and medical units that produce liquid oxygen with their own liquid oxygen generators.

(3) Production over a longer duration, catering to short-term, high-volume needs, such as for large-scale low-temperature tests or rocket launches, involves providing liquid helium, liquid hydrogen, liquid oxygen, and liquid nitrogen using this method.

To accommodate the above situations, effective storage and transportation of low-temperature liquids are necessary. This is particularly cost-effective for departments using gases, as transporting them in liquid form is more economical. For instance, a 3650 L liquid oxygen storage tank holds liquid oxygen with a total weight not exceeding 1250 kg, whereas transporting the same amount of gas would require 500 steel cylinders, weighing 35500 kg. Another example is a 175L liquid oxygen tank with an evaporator, which can be conveniently mounted on a small cart, replacing 20 oxygen cylinders for welding. In summary, storage and transportation of low-temperature liquids are indispensable in almost all applications involving low temperatures, as well as the equipment used for storing them. Therefore, the storage and transportation of low-temperature liquids are one of the most fundamental tasks in low-temperature engineering and also the fastest-developing technology in the field over the past 30 years.

The operating pressure of the low-temperature LNG tank is 0.6-1.44 MPa, with an operating temperature of -162°C. (Available in vertical or horizontal models) The LNG tank consists of two layers, both internally and externally. To minimize the transfer of external heat to the tank, a vacuum insulated structure filled with pearlite sand is used between the layers to provide insulation, isolating it from the atmosphere. This prevents the influence of atmospheric pressure or temperature changes and the entry of humid air into the insulating layer between the inner and outer tanks, effectively ensuring and enhancing the performance of the insulation material.

(Note: Applies to the design and construction of new, expanded, and reconstructed auto gas stations, CNG stations, and combined fueling and CNG stations.)

5. JB/T6869-1997      "Safety Rules for the Use of Low-Temperature Liquid Storage and Transportation Equipment"

(Note: Applies to low-temperature storage and transportation equipment for liquid oxygen, nitrogen, argon, and carbon dioxide in cryogenic containers and tank trucks.)

Low-temperature LNG storage tanks are equipped with multiple valves and piping sections, including: top liquid inlet valve, bottom liquid inlet valve, liquid discharge valve, overflow valve, vent valve, vacuum gauge valve, vacuum pump valve, main liquid inlet valve, gas usage valve, three-way switching valve, inner cylinder safety valve, liquid level display gas phase valve, also known as the balance valve, vacuum gauge, outer cylinder explosion-proof device, pressure gauge, liquid level gauge, pipeline safety valve, and remote transmission interface valves, etc. The material of the valves is extremely important; substandard materials can lead to external or internal leakage of the shell and sealing surfaces; the comprehensive mechanical properties, strength, and rigidity of the components may not meet the usage requirements and could even fracture. Therefore, material selection is the primary and critical issue in the process of choosing low-temperature storage tank valves. The company has strict requirements for the selection of its product valves and piping, ensuring quality and performance through rigorous screening by professionals, to guarantee the safety and peace of mind of our customers.
