What is the service life of vehicle gas cylinders?
2 Answers
The service life of vehicle natural gas cylinders is 15 years. Vehicle scrapping standards: The "Vehicle Scrapping Standards" issued by the state in 1997 stipulate that the scrapping mileage for vehicles is 300,000-500,000 kilometers depending on the model and purpose, with a renewal and scrapping period of 8-10 years; vehicles that still fail to meet the "Technical Conditions for Safe Operation of Motor Vehicles" after repair and adjustment should be scrapped. Precautions: During normal use of a vehicle, its performance will decline with the increase of years. When it reaches a certain period, it must be scrapped for driving safety.
As an ordinary owner of a CNG-powered vehicle, I've personally experienced the issue of gas cylinder lifespan over the years. Generally speaking, the service life of automotive gas cylinders like CNG tanks is 15 years, a standard based on safety regulations and material aging risks. Using them beyond this period may lead to internal corrosion or abnormal pressure, increasing the risk of leaks or explosions. I recommend conducting a visual inspection annually to check for unusual rust or damage, while getting a professional inspection at a certified maintenance facility every two years. Cost-wise, a routine inspection typically costs a few hundred yuan, but replacing a new cylinder can range from several thousand to tens of thousands depending on the vehicle model and brand. I once suffered consequences for neglecting inspections when my car issued a warning mid-journey, causing significant inconvenience. Remember, when the cylinder reaches its lifespan, replace it decisively without hesitation—it's a habit that prioritizes life safety.
