30立方LNG储罐 60立方天然气储罐 100立方液化天然气储罐厂家

The operational 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 designs) The LNG tank consists of two layers, both internally and externally. To minimize heat transfer from the outside to the inside, a vacuum-insulated sandwich panel structure filled with diatomaceous earth is used between the layers, isolating it from the atmosphere. This prevents the impact of atmospheric pressure or temperature changes and the entry of moist air into the insulation layer between the inner and outer tanks, effectively ensuring and enhancing the performance of the insulation material.

Safety regulations and standards for fixed pressure vessels

1. GB/T18442-2011 "Fixed Vacuum Insulation Low-Temperature Pressure Vessel"

2. GB50028—2006 "Code for Design of Urban Gas Supply Systems"

(Note: Applicable to the design of new, expanded, or reconstructed urban gas pipelines for various users, including residential, commercial, industrial production, heating, ventilation, and air conditioning, etc., in cities, towns, or residential areas.)

3. GB50494—2009 "Urban Gas Technology Code"

(Note: Applicable to the construction, operation, maintenance, and use of urban gas facilities.)

4. GB50156—2012 Design and Construction Code for Gasoline and Gasoline Filling Stations

(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 transport equipment for liquid oxygen, nitrogen, argon, and carbon dioxide in low-temperature liquid 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, draining valve, main liquid inlet valve, gas usage valve, three-way switch valve, inner cylinder safety valve, level gauge gas phase valve, also level equilibrium valve, vacuum gauge, outer cylinder explosion-proof device, pressure gauge, level gauge, pipeline safety valve, remote interface, and other valves. The material of the valves is very important; substandard material can cause external or internal leakage of the shell and sealing surfaces, and the comprehensive mechanical properties, strength, and stiffness of the components may not meet the usage requirements, leading to potential fractures. Therefore, when selecting valves for low-temperature storage tanks, material selection is the primary and critical issue. The company has strict requirements for the selection of its product valves and pipelines, ensuring quality and performance through professional screening, guaranteeing customer safety and peace of mind.

Horizontal 60-cubic-meter LNG Storage Tank, Manufacturer of Liquefied Natural Gas Storage Tanks

LNG tanks are low-temperature insulated pressure vessels that can be refilled multiple times. They feature high gas tightness, low thermal conductivity, excellent insulation properties, minimal evaporation loss, and a long service life. They have been mass-produced through a continuous production line. Heze Boiler Factory produces 3-cubic, 5-cubic, 10-cubic, 15-cubic, 20-cubic, 30-cubic, 50-cubic, 60-cubic, and 100-cubic low-temperature LNG tanks, as well as customized specifications.

The operational pressure of the LNG low-temperature storage tank is 0.6-1.44 MPa, with an operational temperature of -162°C, and it is a flat-bottomed double-walled cylindrical design. The tank consists of two layers, an inner and an outer, with an insulating structure between them to serve as the cooling layer. The inner tank is used for storing liquefied natural gas, while the outer shell provides protection and cooling. To minimize heat transfer from the outside to the tank, the inner and outer tanks are designed to be separate and independent. The tank is composed of a carbon steel vacuum shell and a pressure vessel placed within it. The tank can operate under low to medium pressure as per actual design requirements. The explosion-proof diaphragm and safety valve can protect the tank in case of excessive pressure. The safety relief device is designed to protect the internal pressure vessel and vacuum shell, with its use and type determined by the GB150 and "Fixed Container Regulations." This includes a safety relief valve and explosion-proof device for protecting the internal pressure vessel, as well as an explosion-proof cover for protecting the vacuum shell (outer shell). The tank is designed and manufactured for safety, reliable operation, and durability (can operate faultlessly for years), and strict adherence to proper safety and operational procedures is required when operating the tank.

LNG storage tanks are the main equipment of LNG gasification stations, directly affecting their normal production and comprising a significant portion of the construction cost. They can be categorized by structure into underground tanks, above-ground metal tanks, and metal prestressed concrete tanks. For LNG storage tanks, there are currently vacuum powder insulation tanks, positive pressure pile insulation tanks, and high vacuum layer insulation tanks. Medium and small-scale gasification stations typically opt for vacuum powder insulation type low-temperature storage tanks. The tanks are divided into inner and outer layers, with the gap filled with mica sand and vacuumed to reduce the transmission of external heat, ensuring the daily gasification rate of LNG inside the tank is less than 0.3%.
