I would appreciate it if experts could tell me: is the safety level of pressure vessels determined by one’s own company or by the special equipment supervision authorities? We need a pressure vessel inspection plan and information regarding the safety level status to fill out (it’s new equipment, and it hasn’t been put into use yet). I don’t think I’m qualified to fill in that safety level information
Check the \"Rules for Periodic Inspection of Pressure Vessels\"
The safety level of new equipment is generally Grade 1; after about 6 years, it is inspected by a special equipment inspection agency (usually a Special Equipment Inspection Institute or a Boiler Inspection Office) for re-evaluation
The safety status of pressure vessels is classified into grades 1 to 5 (grade 1 is the highest, and grade 5 is the lowest). For newly manufactured pressure vessels, their safety condition grade at the time of commissioning is determined in accordance with the \"Rules for the Management of Pressure Vessel Use\" (TSG R5002-2013); if all manufacturing documents are available at the time of registration for use prior to commissioning, their safety condition grade is registered as Grade 1 ； The safety grade of imported pressure vessels is determined by the special equipment inspection agencies responsible for supervising and inspecting such vessels). For pressure vessels in use, the inspection agency assesses their safety status level in accordance with the relevant provisions of Chapter 4 of the Pressure Vessel Inspection Regulations, based on the defects identified during regular inspections. For the original text, see the definition in Article 5 of the \"Rules for Periodic Inspection of Pressure Vessels\" (TSG R7001-2013).
Pressure vessels that leave the factory in their complete form do not require installation inspection, and their safety status level is generally grade 1 at the time of registration for use. The first comprehensive inspection is carried out after three years; at that time, the inspection agency assigns a safety status rating based on the inspection, and then determines the date for the next inspection.
The newly installed equipment undergoes its first comprehensive inspection three years after installation; at that time, the inspection agency assesses its safety status and assigns a grade, after which the date for the next inspection is determined. It’s not 6 years! ! !
For new pressure vessels, it is necessary to go to the registration authority to obtain a use permit, and the safety level must be determined by the registration authority.
