Pending R Stamp With a Repair Job Already Sold
A fabrication shop holds ASME U and S stamps and has applied for an NBBI R stamp to repair fire-tube boilers. Its written QC manual was written for new construction: it references ASME Section IX for welding and ASME Section VIII for design, but it does not mention NBIC Part 3, repair reports, or the R stamp symbol. The shop intends to subcontract ultrasonic examination and post-weld heat treatment to two local firms. At the accreditation review, the NBBI assessor finds no procedure for evaluating or controlling those subcontractors, and no description of how the authorized inspector will be notified before a repair. The shop already has a purchase order to repair a 125-psig boiler next month. The owner asks whether the shop can start the job under its U stamp while the R stamp application is pending.
1. What QC manual deficiencies must be corrected before the shop can receive an R stamp, and why does each matter?
Read the worked answer
The manual must be rewritten to cover the R stamp scope, not just new construction. At minimum it must define: control of the R stamp symbol and nameplate marking; preparation, review, and distribution of NBIC repair and alteration reports; inspector notification and hold points; evaluation and control of subcontractors such as NDE and heat treatment; design control for alterations; material control; welding procedure and performance qualification; NDE; calibration; nonconformance control; and records retention.
Each item matters because the NBBI review tests whether the shop can demonstrate control of repair work before the stamp is issued. A manual that references ASME Section IX but says nothing about NBIC Part 3 or repair reports leaves the shop without a controlled process for the very activity the R stamp authorizes. The subcontractor gap is also serious: the R stamp holder remains responsible for subcontracted NDE and heat treatment, so the manual must say how those firms are approved, how their procedures and personnel are accepted, and how the authorized inspector gains access to their work.
2. Can the shop start the boiler repair under its U stamp while the R stamp application is pending? Explain.
Read the worked answer
No. The U stamp authorizes new construction under the ASME Code; it does not authorize repairs or alterations under NBIC. Starting the repair before R stamp accreditation would mean the organization is performing R stamp work without the credential, and it could not properly issue an R-1 repair report or apply the R stamp. The customer purchase order does not create authority.
The compliant options are to wait for R stamp accreditation, to have an accredited R stamp holder perform the repair, or to renegotiate the schedule. If the shop starts work and later tries to document it as an R stamp repair, the inspector and jurisdiction are likely to reject the report because the organization was not accredited when the work was performed. The shop should also confirm any state or local requirements before scheduling the job.
3. How should the shop control the NDE and PWHT subcontractors once accredited?
Read the worked answer
The QC manual must include a written subcontractor control procedure. The shop should evaluate each subcontractor's capability, approve the specific procedures and personnel, verify equipment calibration, and define how the R stamp holder reviews and accepts the subcontractor's reports. Purchase orders should reference the applicable NBIC, ASME, and QC manual requirements. The authorized inspector must be given access to the subcontractor's work and records at the required hold points.
The R stamp holder cannot simply receive a subcontractor report and treat it as accepted. It must verify that the correct procedure revision was used, that personnel qualifications were valid, and that the results meet the acceptance criteria. Those records become part of the repair file and support the R-1 report. If a subcontractor is changed or a new process is added, the manual and approval records should be updated before work begins.
