Resource Requirements for Pressure Vessel Manufacture Licensing
Section 1 Basic requirements
Article 15
The applicants for pressure vessel manufacture licensing must have business license or have registered in relevant local governmental departments where the manufacturer is located.
Article 16
The manufacturers of pressure vessel, that have been granted level A1, level A2 or level C manufacture license, will be granted level D License automatically. No manufacture license is required for those manufacturers who produce pressure vessel products with design pressure less than 10 MPa, the same time the maximum inner diameter less than 150mm and the water volume less than 25L. Similarly, manufacture licensing is also unapplied to those products, such as, shells of dependent pressure parts attached to machine, sleeved-tube type heat exchanger without shell, corrugate plate heat exchanger, air-cooler and cooling panel. The manufacturer who produces pressure-containing shell with irregular shape should report Safety Supervision Administration of AQSIQ in order to determine if the application for manufacture licensing is required.
Article 17
Quality assurance system staff for pressure vessel
Pressure vessel manufacturer should provide the following quality control system with responsible persons having relevant professional knowledge, experience and suitable for the manufacturing products.
1. Responsible persons for design and technological process control system
2. Responsible persons for material quality control system
3. Responsible persons for welding quality control system
4. Responsible persons for chemical and physical testing quality control system
5. Responsible persons for heat treatment quality control system
6. Responsible persons for NDT quality control system
7. Responsible persons for pressure testing quality control system
8. Responsible persons for final inspection and testing quality control system
Article 18
Technical staff
The pressure vessel manufacturer should have all the professional technical staff that meets the demand of pressure vessel manufacture and management. Technical staff for various manufacture licensing levels of pressure vessel should meet the following requirements:
1 Technical staff in the manufacturers of licensing level A1 and level A2, level C and level B1 have to be no less than 10 % of all employee and there should be professional technical persons with relevant knowledge suitable for the requirements of manufacturing product.
2. Technical staffs in manufacturer of level A3, level A4, level A5, level B2 and level B3 have to be no less of 5 % of all employee and not less than 5 persons and there should be technical persons with relevant knowledge suitable for the requirements of manufacturing pressure vessel products.
Article 19
Professional operator
1. Among all levels of pressure vessel manufacturers, the manufacturer of welded pressure vessels should have qualified welders and welding operators to meet the demand of products.
1) Level A2 and level A3 and Level C licensing manufacturer should have at least 10 qualified welders and welding operators who have at least 4 granted items together.
2) Level A1, level A5, level B2 and level B3 licensing manufacturer should have at least 8 qualified welders and welding operators who have at least 3 together granted items (except for non-welded vessels manufacturers).
3) Level D licensing manufacturer should have at least 6 qualified welders and welding operators who have at least 2 granted items together.
2. All levels of manufacture licensing pressure vessel manufacturers should have the assemblers who can meet the requirements of pressure vessel production.
3. Among all levels of pressure vessel manufacturers, those who consign the NDE to other enterprises should have high- and middle-level of responsible qualified NDE examiners in accordance with the manufacture level. If the manufacturers themselves perform the NDE, the qualified NDE examiners should meet the following requirements:
1) Level A1 licensing manufacturer should have at least one qualified high-level RT (or UT, MT, PT) examiner who is responsible for NDE.
2) Level C licensing manufacturer should have at least one qualified high-level RT (or UT) examiner and two qualified middle-level RT and UT examiners respectively.
3) Level A2 and level A3 licensing manufacturer should have at least three qualified RT and UT middle-level examiners respectively, and the responsible person for NDE should hold middle-level certificate or higher.
4) Level A5, level B2 and Level D licensing manufactures should have at least two qualified RT and UT examiners respectively and the responsible persons for NDE should hold middle-level certificate or higher.
5) Level B1 licensing manufacturer should have at least two UT and MT examiner respectively and the responsible persons for NDE should hold middle-level certificate or higher.
6) Level B3 licensing manufacturer should meet the requirements of level B1 or level B2 for the number and level of NDE examiners provided it needs to perform NDE.
Article 20
Pressure vessel manufacturers licensing on all levels should have suitable workshop, machining tools, forming equipment, cutting and welding machines, lifting appliances, and necessary fixtures and should meet the following requirements:
1. Enough warehouse or specific areas with effective protection measures for storing pressure vessel materials; distinctive marks should be put between areas for the acceptable materials and unacceptable materials.
2. Specific warehouse with drying and temperature maintain ovens, suitable for welding materials storage.
3. The manufacturer should have enough working site for radiographic testing and welding lab suitable for the requirements of product production.
Section 2 Specific requirements
Article 21
All levels of pressure vessel manufacturers should meet specific requirements in articles 22-25.
Article 22
Specific requirements for level A pressure vessel manufacture licensing
