Heat Exchanger Repair
When your heat exchangers arrive at our shop for repair, our expert teams rapidly inspect and diagnose your units for both common and highly complex issues. Prior to work commencing, all needed repairs—and options—are discussed with the customer. Common repairs include:
Gasket surface repair

Weld repairs

Weld build-up & re-machining

Replacement components

Repairs to shell & channel
components

Coating & paint application
The most common types of weld repairs we perform are weld build-up repair of eroded and/or corroded areas, removal of cracks—and re-weld of those defects, and weld build-up for reclaiming gasket surfaces.

Any defects we find are removed by following the ASME Section IX qualified weld procedures.
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 operatong conditions or to suit new applications at your ASU.

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.

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.
