ENGINEERING RE-RATE
& MODIFICATION
Shell & Tube Heat Exchanger & ASME Pressure Vessel Re-Rating & R-Stamp Modification
Heat Exchanger Solutions Specialist
EXPERT ENGINEERING RE-RATE & MODIFICATION
We can re-rate, adjust, upgrade, or reconfigure your current shell and tube heat exchanger or ASME pressure vessel to suit new conditions or applications—often at significantly lower cost than investing in a newly fabricated unit.
ENGINEERING RE-RATE
In some cases, heat exchangers and pressure vessels can be re-rated without requiring any modification. Our expert engineering teams can deliver a thorough evaluation—and all necessary documentation—to confirm the existing design will safely and efficiently perform to the new specifications, as required by owners and regulators alike.
ASME U-STAMP REPAIR & R-STAMP MODIFICATIONS
Whether or not re-rating is required, we can assist with virtually any shell & tube heat exchanger or ASME pressure vessel repair and/or alteration including design, configuration, options/features, or materials of construction.
All modified units will meet all applicable ASME, NBIC, TEMA, and API codes and standards

ApplicationsWe can re-rate, adjust, upgrade, or reconfigure your current shell and tube heat exchanger or ASME pressure vessel to suit new operating conditions or to suit new applications at your plant.
Rerating:
After a thorough evaluation of your unit, we'll discuss any needed modifications with you prior to beginning any work. If your unit already meets new requirements and/or once updates have been made, we'll provide all necessary documentation—to confirm the existing design will safely and efficiently perform to the new specifications, as required by owners and regulators alike.
