Can the cylinder be replaced if it is scrapped? Now

I can't. According to the regulations of relevant departments, the gas cylinders of oil-to-gas vehicles should be inspected once every two years. Once the cylinder is worn or damaged, it should be replaced immediately. So the cylinder can't be replaced if it is scrapped. The life of cars is ten years, so just tear them down when they expire. Gas cylinder refers to a mobile pressure vessel with a nominal volume of no more than 1000L, which is used to contain compressed gas (including permanent gas, liquefied gas and dissolved gas).
