What essential equipment is required for manufacturing Class D pressure vessels?

1. Stick arc welding machine, submerged arc automatic welding machine； Stainless steel and non-ferrous metal container manufacturing enterprises must have specialized welding equipment (the number required may vary by province) ； 2. It should be equipped with machining equipment suitable for the manufacturing of pressure vessels ； Stainless steel and non-ferrous metal container manufacturing enterprises must have specialized machining equipment ； 3. It should have heat treatment equipment suitable for pressure vessel manufacturing (subcontracting is permitted) ； 4. The rated lifting capacity of the main workshop is ≥10t ； 5. Cutting equipment suitable for pressure vessel manufacturing should be available ； Stainless steel and non-ferrous metal container manufacturers must have specialized cutting equipment and must not use it in combination with carbon steel. 6. ≥1 set of welding rod drying and insulation equipment, ≥1 set of flux drying and insulation equipment, ≥6 welding rod insulation sleeves (the required quantity may vary by province) ； 7. The hydrostatic testing equipment shall be equipped with a pressure testing device that meets the requirements for hydrostatic testing of pressure vessels ； 8. Pressure and airtightness testing equipment: At least 1 air compressor, whose performance should be suitable for carrying out pressure and airtightness tests on pressure vessels ； 9. The forming equipment should include 1 roll former with a rated capacity of ≥20 mm ； 10. Instruments and meters: At least 1 thickness gauge, at least 1 gloss meter, at least 1 film viewing lamp ； 11. Equipment related to non-destructive testing: at least 1 film developing unit, at least 1 ultrasonic flaw detector, at least 1 magnetic particle flaw detector, and at least 1 radiographic flaw detector ； 12. Metallographic and physical-chemical equipment: There should be metallographic and physical-chemical equipment that meets the requirements ； 13. Inspection tools: There should be inspection tools and templates suitable for the manufacturing of pressure vessels. The above are the conditions for D-class container manufacturing equipment in our province; among them, non-destructive testing, heat treatment, and physical and chemical testing can be subcontracted. As for the requirements in your area, you should consult the local safety supervision authorities, as the licensing requirements in different provinces may vary from those set by the General Administration of Quality Supervision, Inspection and Quarantine. For reference only.

Look for Document No. 194 on the forum; it contains detailed regulations

It is best to consult the local safety supervision agency, as their regulations are quite detailed

Thank you, 2nd floor. There is another question: does the non-destructive testing subcontracting still require an exposure chamber?
