What are the differences in manufacturing between atmospheric pressure vessels and pressure vessels?
The main difference is that atmospheric pressure vessels do not require any specific manufacturing qualifications from the manufacturer, but the qualifications required for welders remain the same as those for pressure vessels.
After the pressure vessel is manufactured, it must be registered with the relevant authorities. Is there any difference in the manufacturing process? Waiting for the expert. .
Before manufacturing a pressure vessel, an application for registration must be submitted to the Special Inspection Agency; the manufacturing process is supervised by this agency, and completion documents must be provided upon completion. Atmospheric pressure vessels do not require these; they can be manufactured simply according to the design drawings.
Theoretically, pressure vessels need to be inspected, while vessels under atmospheric pressure do not; all other requirements are met by manufacturing in accordance with the drawings and relevant standards.

Perhaps the requirements for non-destructive testing of atmospheric pressure vessels, as well as the manufacturing tolerances and allowable defects, are not as stringent as those for pressure vessels; it ultimately depends on their respective manufacturing standards
The implementation standards for design, manufacturing, and inspection vary, but if it is a responsible company, atmospheric pressure vessels can also be manufactured and inspected in accordance with the standards for pressure vessels. In fact, as long as manufacturing follows the relevant procedures and standards, the production costs of both types of vessels are roughly the same. Manufacturing pressure vessels involves significant responsibilities, so it is advised not to always seek shortcuts
