R-Stamp certified pressure vessel repair and alteration
Our National Board R Certificate of Authorization covers the repair and alteration of Section VIII, Division 1 metallic pressure vessels, to National Board Inspection Code and jurisdictional requirements.
We do the work at our Hackensack shop or at your site, and Hartford Steam Boiler (HSB) inspects it.
What we repair and alter
- Weld repairs to shells, heads, and other pressure-retaining parts.
- Nozzle repairs and replacements.
- Patch and insert plate repairs for corrosion or damage.
- Alterations that change a vessel's rating, capacity, or intended service.
- Repairs to vessels used in chemical, process, and industrial service.
Every repair follows a written quality system, is inspected by HSB, and comes with a documented repair
record for your files.
How it works
We follow the same five-step process for every R-Stamp job: you tell us what you have, we do a site survey, we prepare the repair plan and coordinate with HSB, we complete the repair and inspection, and you get the documentation. See the Full R-Stamp process for details.

What size or type of vessels do you work on?
We repair and alter Section VIII, Division 1 pressure vessels across a range of sizes and services. Tell us what you have, and we'll confirm it's a good fit.
Can a vessel be repaired without shutting down my whole line?
In many cases, yes — it depends on how the vessel is tied into your system. We'll go over scheduling options during the site survey.
What documentation do I receive?
