Zhongjie Manufacturing Liquefied Natural Gas Storage Tank 30 cubic LNG Storage Tank Specification and Model

Description :

　　Common structures for LNG storage tanks include vertical LNG storage tanks and horizontal LNG storage tanks

　　Vertical LNG storage tank:

　　There are capacities of 10/20/30/50 cubic meters and 60/100 cubic meters

　　Horizontal LNG storage tank:

　　There are capacities of 10/20/30/50 cubic meters and 60/100 cubic meters

　　The LNG storage tank is the main equipment of the LNG gasification station, which directly affects the normal production of the gasification station and also accounts for a large proportion of the cost. According to their structural form, they can be divided into underground storage tanks, above ground metal storage tanks, and metal prestressed concrete storage tanks. For LNG storage tanks, there are existing vacuum powder insulated storage tanks, positive pressure stacked insulated storage tanks, and high vacuum layer insulated storage tanks. Small and medium-sized gasification stations generally use vacuum powder insulated low-temperature storage tanks. The storage tank is divided into two layers, inner and outer. The interlayer is filled with pearl sand and vacuumed to reduce external heat transfer and ensure that the daily gasification rate of LNG in the tank is less than 0.3%

　　The operating pressure of LNG low-temperature storage tanks is 0.6-1.44MPa, and the operating temperature is -162 ℃. The tank body is composed of two layers (vertical or horizontal). In order to reduce the transfer of external heat into the tank, a vacuum filled pearl sand insulation structure is used between the two layers to isolate them from the atmosphere, avoiding the influence 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 improving the effectiveness of the insulation material.

　　High safety requirements. Due to the low-temperature liquid stored in the tank, in the event of an accident, the refrigerated liquid will evaporate in large quantities, with a gasification amount approximately 300 times that of the original refrigerated state, forming an automatically detonating gas mass in the atmosphere. Therefore, API, BS and other specifications require storage tanks to adopt a double-layer wall structure and use the sealing concept. In the event of a leakage in the layered tank, the second layer of the tank can completely seal off the leaked liquid and evaporated gas, ensuring storage safety.

　　Introduction to Tank Pipeline:

　　The low-temperature storage tank is equipped with multiple valves and pipeline parts, including top inlet valve, bottom inlet valve, liquid discharge method, overflow valve, vent valve, vacuum gauge valve, vacuum valve, inlet main valve, gas use valve, three-way switching valve, inner cylinder safety valve, liquid level display gas phase valve, also a display balance valve, vacuum gauge pipe, outer cylinder explosion-proof device, pressure gauge, liquid level gauge, pipeline safety valve, remote transmission interface and other valves. The material of the valve is very important. If the material is not qualified, it will cause external or internal leakage of the shell and sealing surface; The comprehensive mechanical properties, strength, and rigidity of the components cannot meet the requirements for use and may even fracture. Therefore, in the process of selecting valves for low-temperature storage tanks, material is the primary and key issue.
