"Gas tank", also known as liquefied petroleum gas cylinder (cylinder for short), will be automatically scrapped from the factory date to 15 years later. Before 12, it was tested every 4 years, and the fourth test period was 3 years. If the gas cylinder is seriously damaged or rusted during the inspection and does not meet the national standards, it also means scrapping.

Note: Gas cylinder testing must be a professional gas cylinder testing station recognized by the state, and private individuals are not allowed to test without authorization.

Extended data:

Gas tank (liquefied petroleum gas cylinder) is a kind of cylinder for storing gas. The cylinder wall thickness is about 2.5 mm, the internal pressure is 0.5~ 1.2 MPa, the safe service life is 15 years, and it needs to be checked regularly every four years.

In the late 1970s and early 1980s, families in some cities in China began to bid farewell to briquette stoves and use gas tanks. The gas tank was a novelty at that time, and many people were afraid to put it with the stove. Because the price is more expensive, it is usually put in the house, hit the wall and put outside the pipe, and cook outside.

In the middle and late 1980s, a large number of urban residents began to use gas tanks. Changing gas tanks became a unique "landscape" and later developed into a service industry. Pipeline gas gradually enters residents' homes. Compared with gas tanks, pipeline gas is safe, stable, clean and easy to use, which is the product of China's economic and social development.
