National Board of Boiler and Pressure Vessel Inspectors

IMI Industrial Services Group is excited to announce that we are now R Stamp* certified!
This means we are licensed to repair and/or alter boilers, pressure vessels, and other pressure-retaining items.

Our Piping Department & Quality Manager put in long hours working towards this goal. The authorized inspection agency reviewed IMI’s quality manual, our policies & procedures, and spent time touring our shops. They also reviewed and tested many of our welds. We’re proud of our team for all of the hard work that they put forth.

As we expand our capabilities to better meet your needs, we also want to strengthen our relationship with you by continuing to provide the quality, expertise and services that you have come to expect. If IMI can be of assistance to you, please contact your current IMI Project Manager or Field Representative. If you haven’t done business with us in the past, give us a call, or email

We look forward to hearing from you!
