Recently, the State Administration for Market Regulation issued a announcement regarding matters related to administrative permits for special equipment. In order to thoroughly implement the \"Opinions of the Central Committee and the State Council on Promoting Reform and Development in the Field of Work Safety\" as well as the State Council’s requirements for carrying out the reform of separating licensing from regulation across the country, to advance the implementation of the \"Top-Level Design Plan for Reforming the Supervision of Special Equipment,\" to effectively reduce the institutional transaction costs for enterprises, and to strengthen the supervision of special equipment, the State Administration for Market Regulation has, after seeking extensive feedback, streamlined and integrated the existing licensing procedures for special equipment production, as well as the qualification assessment processes for personnel involved in the operation of special equipment and for those engaged in inspection and testing. The \"Catalogue of Licenses for Special Equipment Manufacturing Units\", the \"Classification and Items for Qualification Assessment of Special Equipment Operators\", and the \"Items for Qualification Assessment of Special Equipment Inspection and Testing Personnel\" have been formulated. The above catalog and items shall come into effect as of June 1, 2019. According to the latest list of administrative permits for special equipment, has the classification of Category 3 pressure vessels been abolished? Also, in the current latest list of administrative permits for special equipment, does it mean that to manufacture Class 3 pressure vessels, one only needs a Class D manufacturing license? Also, the existing A2-class vessels are to be converted into other high-pressure vessels. (But what exactly are these \"other high-pressure vessels\"?) )

It can be produced; first, you need to clarify the definitions of high, medium, and low pressure, as well as categories 1, 2, and 3, and make judgments by referring to Appendix A of the capacity regulations.

Category 3: Medium voltage, Class D; others must be Class A

Liquid ammonia falls under category III pressure vessels, with a design pressure of only 2.2 Mpa. Under the old regulations, an A2 production qualification was required; for low and medium pressure applications, the relevant qualifications are classified as D1/D2 levels; The new regulations have removed the requirement that Category 3 pressure vessels must possess an A2 manufacturing qualification; instead, the A2 qualification has been incorporated into the manufacturing qualifications for other high-pressure vessels, while the manufacturing qualifications for low- and medium-pressure vessels have all been changed to Class D. So now I just need to require the manufacturer to have Class D production qualifications, right?
