Pressure Vessels (ASME Certified)
Ironworks Welding is an ASME-certified fabrication shop providing U-Stamp pressure vessel manufacturing and R-Stamp repair for industrial and energy operations.
ASME Fabrication (R & U Stamp)
ASME U-Stamp Certified Fabrication
Ironworks Welding manufactures ASME Section VIII Division 1 pressure vessels built to the highest standards of quality and safety. Our U-Stamp certification ensures every vessel is engineered, welded, and tested to strict code requirements, giving operators the confidence that their equipment is compliant, durable, and ready for demanding industrial environments.
ASME R-Stamp Repair & Modification
As a certified R-Stamp repair facility, Ironworks performs code-compliant repairs, alterations, and re-ratings on existing pressure vessels. Our QA/QC team documents every weld, test, and inspection to meet NBIC standards, ensuring your repaired vessels return to service safely with full traceability and long-term reliability.
Custom Design & Engineering
Ironworks Welding partners directly with engineers, operators, and project teams to design custom pressure vessels built to exact specifications. Whether it’s a unique operating environment, specific process requirement, or a tight installation footprint, our engineering team ensures every vessel is optimized for performance, durability, and code compliance.
Including:
- Size & Geometry: Vertical, horizontal, saddle-mounted, and specialty configurations
- Pressure Rating: ASME Section VIII Division 1 compliant pressure classes
- Material Selection: Carbon steel, stainless steel, high-alloy materials
- Connections & Nozzles: Fully customizable inlet/outlet orientation and count
- Internal Components: Baffles, trays, diffusers, and process-specific internals
- Operating Environment: High-temperature, corrosive, or high-cycle applications
Vessel Repair & Modification Services
We provide code-compliant repair, alteration, and re-rating services for pressure vessels that are damaged, aging, or operating outside their original specifications. As an ASME R-Stamp certified facility, we perform both in-shop and on-site repairs, ensuring your vessels return to safe, reliable service with full NBIC documentation and traceability.
In-Shop Vessel Repairs
Our ASME-certified fabrication shop handles everything from crack repairs and weld buildup to nozzle replacement, internal component repair, and shell section replacement. Every repair undergoes inspection, testing, and full documentation before release.
On-Site Repair
When equipment can’t be transported, our mobile crew provides field welding, inspection, patching, and alterations directly at your facility. We work quickly and safely to minimize downtime and restore operational integrity.
Alterations & Re-Rating
Ironworks performs alterations, upgrades, and re-ratings to bring vessels back into code or align them with new process requirements. We update ASME R-Stamp ratings, change connections or internals, and ensure all modifications meet quality standards.
