LPG natural gas (LNG) is a liquefied natural gas at extremely low temperature. Low -temperature storage tanks are required during storage and transportation.The structure, operation and safety of this storage tank are completely different from other types of storage tanks.This article will introduce the structure, storage and safety of LPG low -temperature storage tanks.

Construction of LPG natural gas storage tank

LNG storage tanks are usually composed of inner tanks, intermediate pressure areas and outer cans.The inner pot is made of stainless steel or aluminum. It is an important area for storing LNG, which can be affected by low temperature and high pressure.The middle pressure zone is usually built with materials such as foam glass or polystyrene to play a role in insulating insulation.The outer pot is made of reinforced concrete or steel, which has the effect of protecting and increasing structural strength.All cans have multiple layers of insulating materials to keep the liquefied natural gas in a low temperature state.

Storage of liquefied natural gas storage tanks

Storage of liquefaction natural gas requires certain conditions, such as constant low temperature and high pressure.Because the temperature of LNG is only -162 ° C, it must have a high level of insulation performance for the storage tank.In addition to thermal insulation performance, storage of liquefied natural gas also needs to maintain constant storage pressure to ensure its stability and reliability.These requirements have high requirements for liquefied natural gas storage tanks because any error may lead to catastrophic consequences.

Safety issues of liquefied natural gas storage tanks

The safety of liquefied natural gas storage tanks has always been the focus of the industry and the public.The safety of liquefied natural gas storage tanks involves many factors, such as the design, construction, operation and maintenance of the tank.Below will focus on the safety of liquefied natural gas storage tanks:

1. Design: The design of LPG storage tanks must take into account various factors such as earthquakes, meteorological, pipe explosion and external force collision.The design scheme must be strictly evaluated and verified to ensure that it can withstand various unforeseen factors.

2. Construction: Construction quality is the basis for ensuring the reliability and safety of the storage tank.During the construction period, it is necessary to operate in accordance with the design plan to ensure that each step is correct.

3. Operation: The operation of liquefied natural gas storage tanks needs to abide by a series of operating procedures, including operations such as loading, uninstallation, storage and transfer of LNG.The operator must receive professional training and certificates to ensure that LNG will not leak or other dangerous accidents during the operation process.

4. Maintenance: The maintenance of liquefied natural gas storage tanks is very important. It must be checked and maintained frequently to ensure the safety and reliability of the storage tank.Maintenance personnel must check and repair regularly to ensure normal operations such as various subsidiary equipment and exhaust systems of the storage tank.


LPG low -temperature storage tank is a very important storage method that can store and transport LNG more secure and efficiently.However, the construction, operation and maintenance of LPG low -temperature storage tanks require very strict requirements and standards to ensure their safety and reliability.In the future, with the continuous growth of industrial development, we also need to continuously improve the liquefied natural gas
