A liquefied gas tank refers to a storage tank used to store liquefied gas. When there is liquefied gas inside, the pressure is very high, and a slight improper operation may cause an explosion. It is a special equipment. The product itself is made of steel and has a certain resistance to pressure. The maximum pressure of the liquefied Gas Cylinder is 2.1 MPa.
The pressure of liquefied gas at 20 degrees Celsius is 0.8 MPa, and the pressure at 40 degrees Celsius can reach 1.59 MPa. If the volume of the liquefied gas remains the same, the pressure will increase by 0.04 MPa for every 1 degree Celsius increase in temperature, so each cylinder can only be filled with 85%, which is 14.5 kg. Do not use warm water to heat the cylinder when the tank is empty, otherwise it will cause a physical explosion. Therefore, liquefied gas tanks must use manufacturers with relevant manufacturing qualifications to produce or use qualified products
GAS COMPOSITION
First of all, what is gas? In chemistry, gas refers to a colorless and odorless mixture of methane-based gas generated from biological fossils. In daily life, gas does not specifically refer to a kind of gas, but a general term for several types of gas, which can be divided into three categories: liquefied petroleum gas, natural gas, and coal gas.
Both liquefied petroleum gas and coal gas are made artificially. Natural gas is commonly known as natural gas. The gas we use daily is mainly liquefied petroleum gas and natural gas. It should be noted that the gas in what we usually call a "gas tank" is not coal gas, but liquefied petroleum gas.
The main components of liquefied petroleum gas are propane and butane, which is a new type of fuel. The use of liquefied gas has the advantages of less pollution, high heat generation, easy transportation, simple storage, etc., so it has already entered the lives of the people. But it has a side effect, that is, if it leaks during use, it will be extremely harmful to the human body.
Both liquefied petroleum gas and natural gas are colorless and odorless, but due to their flammable and explosive characteristics, for safety reasons, the gas supplied to households will be added with a chemical agent that resembles a "smelly" rotten egg. Ethyl mercaptan or today`s tetrahydrothiophene. Under outdoor conditions, since methane is lighter than air, once it leaks, methane will quickly dissipate, which helps reduce the risk of explosion to a certain extent.
