What documents are required for gas cylinder inspection?

[Willie]

For vehicle gas cylinder inspection, you need to bring the following documents to the Special Equipment Inspection Institute: 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. Gas cylinder inspection cycle: According to national standards, the first and second inspections for vehicle gas cylinders should be conducted every 3 years. After the second inspection, inspections should be performed every 2 years. Since taxis have higher refueling frequency, taxi gas cylinders should be inspected every 2 years initially, and then annually thereafter. Annual inspection notes: During the review, you need to bring complete documents including the driving license and compulsory traffic insurance policy, drive the vehicle to the inspection station, and fill out the required forms.
