Generally, you should go to the gas cylinder inspection station of the local Special Equipment Inspection and Research Institute (SEIRI) for cylinder inspection. For the inspection, you need to bring the gas cylinder usage registration certificate from the fuel-to-gas conversion, the gas cylinder factory qualification certificate, the gas cylinder installation supervision inspection certificate, the vehicle's driving license, and the owner's ID card to the SEIRI for inspection. For details, you can inquire the local SEIRI's contact number for consultation. The typical inspection cycle for vehicle gas cylinders is three years. Below is an introduction to gas cylinders: 1. Wide application: Gas cylinders are widely used, almost indispensable in both production and daily life; 2. Pressure-bearing equipment: Gas cylinders are pressure-bearing equipment with explosion risks, and the media they contain are usually flammable, explosive, toxic, or highly corrosive. Their usage environment is more complex and harsh than other pressure vessels due to their mobile nature, repeated refilling, varying operators, and changing usage conditions; 3. Hazards: Once a gas cylinder explodes or leaks, it often leads to fires or poisoning, even causing catastrophic accidents, resulting in severe property damage, casualties, and environmental pollution;

For the gas cylinders on cars, such as CNG or LPG tanks, inspections must be conducted at formal and professional facilities. Generally, you should look for specialized automotive gas conversion workshops, authorized service stations, or inspection agencies. I’ve been driving with a gas cylinder for a long time and know that safety comes first. These cylinders need to undergo pressure tests and leak checks every 2 to 3 years, or else a gas leak could lead to serious trouble. During inspections, they use instruments to check for cracks in the tank body, valve sealing, and other issues. The process is quick but requires an appointment. Don’t try to save money by going to roadside shops—only certified places with proper qualifications are reliable. While driving, pay attention to unusual noises or the smell of gas, and immediately pull over and call for help if detected. Inspection costs depend on the cylinder size and region, usually a few hundred yuan per test, but that’s much better than dealing with a car explosion. Always follow safety regulations and don’t delay inspections to avoid fines or vehicle impoundment by traffic police.

I've been driving an LPG vehicle for several years, and the gas cylinder inspections must be handled at designated service centers. I regularly drive to the spots recommended by the local vehicle management office or large repair shops, as they have professional equipment. The inspection mainly checks the cylinder's pressure resistance and connection stability, taking about half an hour to complete, but you need to bring your vehicle documents and make an appointment. If the cylinder is overdue for inspection and you notice sluggish acceleration or unusual odors while driving, get it checked immediately. The cost isn't high—around 100 to 200 RMB—and you can also have other components inspected, like fuel injectors and pipelines. A reminder: don’t tamper with the cylinder, and unauthorized modifications are even more dangerous. You can find inspection points on map apps—just pick ones with good reviews. Safe driving is crucial, so never skip this step.

To inspect the gas cylinder in your vehicle, you must go to a certified location. I recommend visiting a gas system installation center or an inspection station. The process is straightforward: they first conduct a visual inspection of the cylinder's exterior, then use machines to test internal pressure, ensuring there are no gas leakage hazards. The inspection cycle is typically every few years, depending on the specific cylinder model. The cost is around a hundred yuan, and certified shops will provide you with an inspection report. During the inspection, also check the pipeline connections to avoid issues caused by loose fittings. Avoid opting for unverified small shops for quick service, as it may be unsafe and fail the annual inspection. Remember to inspect on time—safety comes first.
