Gas station supporting equipment, natural gas storage tank, 60 cubic vertical LNG storage tank price

Description :

　　The LNG storage system consists of LNG storage tanks, auxiliary pipelines, and control instruments. The tank body is composed of two layers (vertical or horizontal). The inner cylinder and pipeline materials are made of S30408 (06Cr18Ni9) austenitic stainless steel, and the outer cylinder is made of carbon steel Q345R pressure vessel steel plate. The operating pressure is 0.6-1.44MPa and the operating temperature is -162 ℃. 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.

　　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 evacuated to reduce external heat transfer and ensure that the daily gasification rate of LNG in the tank is below 0.3%

　　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 LNG storage tank pipelines:

　　The LNG storage tank is equipped with multiple valves and pipeline components, including top inlet valve, bottom inlet valve, liquid discharge method, overflow valve, vent valve, vacuum gauge valve, vacuum valve, inlet main valve, gas usage valve, three-way switching valve, inner cylinder safety valve, liquid level display gas phase valve, balance valve, vacuum gauge, 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. The company has strict requirements for the selection of valves and pipelines for its products, and personnel rigorously screen their quality and performance to ensure that customers can use them safely and with confidence.
