The points to be included in the "Notes" section of Form U-1A depend on the type of vessel (e.g., cryogenic, NACE, or lethal service) and the material used (SS, Duplex, or Carbon Steel). Below are the common points to consider:
Common Points to Include in U-1A Notes:
1. Radiographic Examination (RT)
Percentage of the vessel subjected to RT (e.g., "Shell and heads 100% RT per UW-11(a)").
Acceptance criteria (e.g., "RT per ASME Section VIII, Div. 1, UW-51").
2. Post Weld Heat Treatment (PWHT)
If applied, mention the temperature and holding time (e.g., "PWHT at 1150°F for 1 hour per UCS-56").
If exempted, state the exemption clause (e.g., "PWHT not required per UCS-56(d)").
3. Impact Testing
If required, reference the applicable impact test exemption rules (e.g., "Impact tested per UG-84" or "Exempted per UCS-66").
4. Material Certification
If material traceability applies, note it (e.g., "All materials comply with ASME Section II, Part A and B").
Mention any dual-certified materials (e.g., SA-516 Gr. 70 / SA-515 Gr. 70).
5. Special Service Conditions (if applicable)
If designed for cyclic service, reference U-2.
6. Design Code & Special Considerations
Mention any Code Cases used.
Any Finite Element Analysis (FEA) carried out for specific weld joints.
Type of Bolt, Stud, and Washer used.

Our company have ASME certificate of authorization for ASME U stamp
with scop covering
manufacturing activities at shop & field sites controlled by our
company.
We have constructed a pressure vessel at field site owened by our
customer.
Now we have to prepare MDR in U1 form.
My question is againest name & address of manufacturer whether we have
to put field site address or address of our company as apeared on
certificate of authorization.
Please share your experience & views on above.
Thanking you.
