The inspection cycle is divided into: (1) If the safety level is 1 or 2, at least once every six years ； (2) For safety level 3, at least once every 3 years. 3. Withstand voltage test: It refers to the hydraulic test or pneumatic test that exceeds the maximum working pressure when the pressure vessel is shut down for inspection. For fixed pressure vessels, a pressure test must be conducted at least once during each inspection period, and for movable pressure vessels, a pressure test must be conducted at least once every 6 years.

The pressure vessel has been inspected regularly. Does it still need annual inspection?
You have read a lot of posts, and you have replied to a post before and introduced the inspection project in detail. Those that have undergone periodic inspections in the current year generally do not need annual inspections. According to regulations, periodic inspections should be conducted first and then annual inspections. Periodic inspection used to be called comprehensive inspection, which is a method of parking inspection. Annual inspection is a method of online inspection. In fact, annual inspection should be used as an auxiliary inspection method to regular inspection to discover certain problems that cannot be found in regular inspection.
According to the latest regulations, annual inspections and periodic inspections do not interfere with each other, and annual inspections are still required in the year of periodic inspections.
