What procedures are required for the inspection of vehicle gas tanks?

Private vehicle gas cylinder annual inspections are conducted at the Special Equipment Inspection Institute under the Municipal Bureau of Quality and Technical Supervision. For the inspection, you need to bring the gas cylinder usage registration certificate from the oil-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 Special Equipment Inspection Institute. Oil-to-gas conversion maintenance precautions: 1. Conduct a comprehensive gas leakage inspection every half month: Shake water mixed with dishwashing liquid thoroughly and apply it to the vehicle's switches, pressure reducing valves, and other joints. If bubbles are observed, it indicates a natural gas leakage issue, and the vehicle should be sent to a specialized auto repair department for inspection and repair. 2. Regularly maintain the air filter, fuel injection simulator, and pressure reducer: Improper cleaning of the air filter, incorrect adjustment of the fuel injection simulator's injection delay, or improper adjustment of the pressure reducer can cause the oil-to-gas converted vehicle to stall while driving. 3. The service life of a gas cylinder is generally 15 years: For safety reasons, relevant regulations stipulate that oil-to-gas converted vehicles must undergo an annual inspection of the gas cylinder every two years. If the gas cylinder shows wear or damage, it must be replaced before continued use.
When I had my car's gas tank inspected last year for the annual check, I needed to prepare the gas cylinder usage registration certificate and the valid inspection certificate. These two are the basic documents. If any are missing, you have to go to the pressure vessel inspection office to get them reissued. Then, when you go to the inspection station, they will carefully check whether the gas tank's mounting brackets are secure, whether the valves are leaking, and there should be no obvious rust at the pipe connections. Remember to bring the owner's ID card and the original vehicle registration certificate, and you'll also need to pay the inspection fee on-site. The whole process takes about half a day, so it's recommended to call ahead and make an appointment with the inspection station to avoid long waiting times. The gas tank needs to be re-inspected every two years, so make sure not to delay until it's expired.
