What qualifications and regulations are required for manufacturing pressure vessels at atmospheric pressure?
Thread Content
What are the qualification requirements and relevant regulations for manufacturers of pressure vessels at normal pressure? What are the criteria used for equipment acceptance? This requirement is quite vague; please give me some advice! Thank you
No requirements are likely to be imposed regarding qualifications; the standards NB/T47003.1 shall be followed for design, manufacturing, inspection, and acceptance
Manufacturing probably requires a Class D qualification
There are no specific qualification requirements for the manufacturing and design of pressure vessels at normal pressure; it is sufficient to follow the standards NB/T47003.1-2009 for design, fabrication, inspection, and acceptance.
NB/T 47003.1-2009 Welded Steel Pressure Vessels at Atmospheric Pressure
The atmospheric pressure vessel manufacturers I have come into contact with all lack the necessary qualifications; equipment acceptance is primarily based on the drawings, and if there are any issues with those drawings, then NB/T 47003.1-2009 \"Steel Welded Atmospheric Pressure Vessels\" is used as a reference.
:(I don’t know; I work at a company that manufactures pressure vessels.)
No qualification requirements are needed; it is manufactured in accordance with the standards for atmospheric-pressure equipment
