Export 30 cubic meter LNG tanks, manufacturers supply 5-150 cubic meter LNG 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 gaseous natural gas under atmospheric pressure to -162°C, causing it to condense into a liquid. The liquefaction of natural gas significantly reduces storage and transportation space and costs, and it also features 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 becoming a new hot spot in the global energy market.

Overview of Liquid Low-Temperature Storage Tanks and LNG Tanks

With the rapid development of the national economy and the widespread adoption of low-temperature technology, the application of low-temperature liquids is becoming increasingly extensive, including liquid hydrogen, liquid oxygen, liquid nitrogen, liquid argon, liquid helium, and liquefied natural gas, among others. The production, application, and research of low-temperature liquids all require their storage and transportation. Many important scientific research projects must be conducted under low-temperature conditions. The demand for low-temperature storage and transportation containers is continuously growing across various industries, particularly in industrial, agricultural, defense scientific research, and medical fields.

Due to the low boiling point and small latent heat of vaporization of low-temperature liquids, a considerable 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 liquid oxygen generators produced by many testing and medical facilities for the production of liquid oxygen.

(3) Extended production periods for short-term, high-concentration use, such as for large-scale low-temperature tests or rocket launches, involve the provision of 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 essential. For departments using gases, transporting them in liquid form is also quite economical. For instance, a 3650 L liquid oxygen storage tank holds liquid oxygen with a total weight not exceeding 1250 kg, whereas transporting the gas would require 500 steel cylinders, weighing 35500 kg. Another example is a 175L liquid oxygen tank with an evaporator, which can be easily transported on a small cart and can replace 20 oxygen cylinders for welding purposes. 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 a fundamental task in low-temperature engineering and also the fastest-developing technology in the field over the past 30 years.

The operational pressure of the low-temperature LNG storage tank is 0.6-1.44 MPa, with an operating temperature of -162°C. (Available in vertical or horizontal configurations) The LNG storage tank consists of two layers, both internally and externally. To minimize heat transfer from the outside to the inside, a vacuum-insulated sandwich structure filled with diatomaceous earth as a thermal insulation material is used between the layers, isolating it from the atmosphere. This prevents the impact of atmospheric pressure or temperature changes and the entry of humid air into the insulation layer between the inner and outer tanks, effectively ensuring and enhancing the performance of the insulation material.

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, drain valve, main liquid inlet valve, gas usage valve, three-way switching valve, inner cylinder safety valve, liquid level display gas phase valve, level equalization 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; inadequate material 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 customer safety and peace of mind through rigorous quality and performance screening by professionals.
