There are two types of liquefaction tanks used by citizens. One is the screw connection between the cylinder shield and the bottle body, referred to as "screw bottle"; the other is the connection between the cylinder shield and the bottle body by electric welding, referred to as "welded bottle". ". According to national regulations, the safe use period of liquefied gas tanks is only 15 years, and regular inspections are required every 4 years. Since there is no permanent mark on the bottle body of the "screw bottle", since September 1996, the state has clearly stipulated that the "screw bottle" must not be reproduced. That is, the last batch of "screw bottles" produced is more than 15 years old and must be scrapped. The normal service life of liquefied gas tanks is generally 15 years. Within 12 years after leaving the factory, liquefied gas tanks must be tested every 4 years, and must be scrapped for more than 15 years. Of course, some cans that cannot be used for various reasons can not be used again. Don't put your family's safety due to your negligence.

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 butan
CNG GAS CYLINDER PRECAUTIONS FOR USE
2021 / 12 / 01
1. The use and installation of compressed natural gas cylinders for automobiles should comply with the relevant standards, and should be refitted and repaired by a formal refitting factory with CNG auto refitting qualification issued by the province, including installation and disassembly of gas cylinders. It is strictly forbidden for unqualified units to modify, repair, disassemble and inspect the gas cylinders. Do not dig, repair, weld and repair the gas cylinders. The original manufacturing labels and nameplates of the gas cylinders should be complete, the content should be complete, and the steel seal should be clear; No permanent deformation, the bottle valve should be intact; 2. The safety status of the gas cylinder and its accessories should be checked before and after filling; the filled gas must undergo dehydration, desulfurization and light oil removal. .Overpressure filling is strictly prohibited, the natural gas in the bottle must not be used up, and a residual pressure of more than 0.1 MPa must be left; the working pressure of the gas cylinder is the limited filling pressure at the reference temperature (20℃), and the filling pressure of the gas cylinder should be Adjust according to the actual air temperature during inflation, and its temperature compensation value should be in accordance with the regulations of the inflatable station. The new gas cylinder should be vacuumed before the first inflation; 3. During the use of the cylinder, it is found that the amount of air added does not match the usual mileage, or if the pressure in the cylinder drops significantly after a period of exercise, you should be vigilant and check for leaks in time. When there is serious corrosion, damage or doubt about its
