Pressure Vessel Repair & Alteration
Qualified Repairs. Documented Quality. Code-Based Execution.
Pressure-retaining equipment plays a critical role in many industrial facilities. AXLE performs qualifying repairs and alterations under our National Board R Stamp authorization, following a documented quality system and the requirements of the National Board Inspection Code (NBIC).
Whether supporting a planned outage or evaluating an unexpected repair, we help facility owners restore critical equipment with confidence.
When Critical Equipment Can't Wait
Pressure equipment often operates under high temperatures, elevated pressures, and demanding service conditions. When damage is discovered, repairs require more than skilled workmanship—they require careful planning, quality controls, documentation, and compliance with applicable codes.
AXLE supports industrial facilities by performing qualifying pressure equipment repairs and alterations within the scope of our National Board R Stamp authorization.

Why the R Stamp Matters
Not Every Repair Is the Same
Pressure-retaining equipment is subject to requirements that extend beyond workmanship alone.
For qualifying repairs and alterations, the National Board R Stamp signifies that an organization maintains a documented quality system and is authorized to perform work under the National Board Inspection Code.
For facility owners, that means confidence in:
- Documented repair procedures
- Established quality controls
- Inspection and traceability
- Code-based execution
- Proper documentation
