Case 1: Modification order for atmospheric pressure vessels； Case 2: Pressure vessel modification order (Regulatory Authority). Thank you
What specific type of modification is it? Is it a design change order, a material substitution order, a process change order, or a change to the user’s design specifications?
The pressure vessel modification order must be stamped with the design-specific seal
Case 1: The organization’s official seal is sufficient. Case 2: Special seal for pressure vessel design.
Our company’s practice: Use the project liaison seal for modifications to atmospheric pressure vessels, and the special seal designed for pressure vessel design for pressure vessels
