Coker is proud to announce that we have earned the National Board “R” Stamp Certificate of Authorization. This significant accreditation authorizes us to perform code-compliant repairs and alterations on pressure-retaining equipment. This certification strengthens our ability to deliver high-level mechanical, welding, and repair services while meeting the rigorous standards of the National Board Inspection Code (NBIC).
For our industrial, utility, and commercial clients, this means greater capability, greater compliance, and greater confidence on every project.
What the “R” Stamp Certification Means
The National Board “R” Stamp authorizes qualified organizations to perform repairs and alterations to pressure-retaining items in accordance with NBIC Part 3 requirements.
To earn this certification, Coker was required to:
- Maintain a formal Inspection Agreement with an Authorized Inspection Agency (AIA)
- Develop and implement a compliant Quality Control Manual (QCM)
- Successfully undergo a comprehensive facility and procedural review
- Demonstrate technical expertise in repair and alteration activities
The certification is issued only after a detailed review process and must be renewed every 3 years, reinforcing ongoing compliance and accountability.
Why This Matters for Contractors & Industrial Clients
For general contractors, plant managers, utilities, and industrial facilities, working with an R Stamp-certified contractor reduces risk and ensures:
- Code-compliant repairs and alterations
- Proper documentation and reporting
- Qualified inspection oversight
- Registered repair reports where required
- Alignment with jurisdictional and regulatory standards
Because R Stamp holders must follow strict Quality Management System controls, clients can be assured that repairs are performed safely, properly documented, and executed in accordance with nationally recognized standards.
Simply put, this certification helps Coker compete for—and execute—more complex, high-value projects.
