The safety status level is 1-2, usually conducted every 6 years. The safety status level is 3, with inspections generally conducted every 3–6 years. The safety status is rated at level 4, and its inspection cycle is determined by the inspection agency. Pressure vessels with a safety status rating of 4 may not have a cumulative monitoring usage time exceeding 3 years. During monitoring, defects should be addressed to improve its security level. New pressure vessels are generally subject to their first comprehensive inspection after 3 years of operation, and the interval for the next comprehensive inspection is determined by the inspection agency based on the results of that inspection.
