For the three types of external drawings that come with modification notices, is it still necessary to make the changes on the original blueprints as well?
It needs to be modified in the diagram, but these days upgraded drawings are generally used directly
If the modification order is signed and stamped, there is no need to change the blueprint; just keep the modification order together with the blueprint.
The 4th floor is the correct choice; if it’s a significant modification, it’s best to affix the pressure vessel design stamp.
Is modifying the design the responsibility of the design agency? Does the manufacturing unit have the right to make changes?
It is necessary to determine whether the notice of drawing modification was issued by the design unit or the manufacturing unit; if it was the design unit that issued it, the changes should be made on the blueprints. If it is proposed by the manufacturing unit, clear markings must be made on the as-built drawings in accordance with the requirements specified in the written approval document from the design unit; such markings shall include the signature of the person who made the changes along with the date of the change.
As long as a license for the design and manufacture of pressure vessels is obtained, there must be a quality assurance manual (or quality manual), along with procedural control documents regarding changes to the design documents. The modification procedures may vary among different units; just follow the requirements of the respective control procedures.

These are the regulations for preparing as-built drawings; the \"Solid Content Regulations\" specify the details.
Of course it needs to be modified, and all the drawings must be altered; furthermore, the modified areas should bear the signature of the technical staff along with the date of modification. Otherwise, oversights are likely to occur during on-site production; it’s impossible to expect workers to find the design change orders and check the drawings every time they work!
