When is code stamping applied?

When is code stamping applied?

• A. After inspection and hydrotest approval
• B. Before inspection
• C. After fabrication
• D. During design stage

Answer: (A)

The stamp is the official certification that the vessel meets ASME Code requirements, and it is applied once the vessel has passed the required verification steps. An Authorized Inspector reviews the fabrication, materials, welding, nondestructive examinations, and the results of the hydrostatic test, and only after these inspections are approved is the code stamp placed. This ensures the vessel is compliant and safe to leave the shop and enter service. It isn’t applied during design, before inspection, or merely after fabrication without the accompanying inspection and hydrotest results.
