Brief Introduction: Product description LNG full containment tanks have been developing alongside the LNG industry, with LNG storage becoming increasingly large-scale and at normal pressure. Domestic design and manufacturing have reached 50,000m3, and single units of 250,000m3 and 160,000m3 LNG normal pressure storage tanks have been established along the coast to receive ship-borne LNG. Currently, the LNG storage tanks designed, manufactured, and installed domestically are mainly 5,000m3 and

Product Description
LNG Full Containment Tank
With the development of the LNG industry, LNG storage is becoming increasingly large-scale and at normal pressure. Domestic design and manufacturing have reached 50,000m³, and single units of 250,000m³ and 160,000m³ LNG normal pressure storage tanks have been established along the coast to receive ship-borne LNG. Currently, the LNG storage tanks designed, manufactured, and installed domestically are mainly 5,000m³ and 10,000m³, widely used in LNG liquefaction plants or LNG peak shaving stations. The amount of LNG produced from industrial waste gas is generally small, and 1,000m³ LNG storage tanks are commonly used.
