Low-temperature storage tanks are primarily used in the industrial gas sector, with a broad industry application. This includes steel mills, chemical industries, oil, food, and aerospace, among others, all requiring gases. Industrially, gases like oxygen, nitrogen, and argon, which are in high demand, are separated from air using air separation equipment. The air is compressed and liquefied, then separated based on the different boiling points of oxygen, nitrogen, and argon, before being stored in low-temperature storage tanks.

    Liquefied Natural Gas (LNG)The tank features a long service life, compact structure, minimal land occupation, centralized control, ease of operation, and convenient maintenance. It is a double-layer fixed vacuum powder insulation low-temperature storage tank. The inner shell is made of stainless steel.,Outer shell material isQ235BOr16MnRThe liquid oxygen tank surface is coated with anti-corrosion materials using processes such as sandblasting, sweeping, and spraying, while a two-component rapid curing liquid paint is also employed.

The Liquefied Natural Gas (LNG) storage tank consists of the tank body, instruments, pipelines, valves, etc. The LNG storage tank features two liquid inlet methods, top and bottom, which can be selected and used according to the actual situation.

The inner tank of the Liquefied Natural Gas (LNG) storage tank is equipped with a safety system device featuring dual safety valves. In normal operation, one set is in active mode while the other is on standby. Should the active safety valve trip, the manual pressure relief valve is immediately opened to relieve pressure to the tank's maximum working pressure. Simultaneously, the safety device is swiftly switched to the standby system via the manual handle, effectively ensuring the tank's safety. This safety system consists of safety valves, explosion-proof devices, vent valves, and three-way ball valves, not only enhancing pipeline welding but also boasting excellent fire and static electricity prevention structures. Additionally, the safety relief openings on the casing are designed to ensure the overall safety and reliability of the equipment. The low-temperature pipeline is centrally extracted for operation and control, and the extraction point is constructed with Duralumin pipes to meet low-temperature requirements and reduce stress caused by thermal expansion and contraction, thereby ensuring the tank's safety. The vacuum extraction valve is sealed with three "O" rings, effectively guaranteeing the reliability of the sandwich seal, and is made entirely of stainless steel with a compact design. The top of the LNG storage tank features a research and development suspended structure for ease of transportation, lifting, and installation. A unique manhole design is customized to ensure cleanliness inside the inner tank when it is sealed. Vacuum isolation valves and a combined vacuum gauge valve are used on the LNG storage tank for measuring and maintaining the vacuum degree of the tank's sandwich, extending the tank's lifespan and improving its quality. The LNG storage tank is equipped with a level gauge and pressure gauge for local display of liquid level and pressure.
