Integrated Global Services Inc.Coal-fired boiler life extension
Protect serviceable boiler tubing in situ with HVTS® cladding, applied at rates up to 5× faster than alternative methods, helping reduce repeat repairs and unnecessary panel replacement. Multi-asset support also covers gas turbines and HRSGs.

Outage execution
As power demand rises, outage windows are not getting longer. Inspection and UT data distinguish defects requiring local repair from serviceable tubing that can be retained and protected. When damage extends beyond localized repairs, application speed determines how much risk can be removed before restart.
Three failure drivers to control: Fireside corrosion Erosion Thermal cycling
Technical approach
The final protection scope is confirmed from inspection findings, tube metallurgy and UT results, with replacement limited to defects that are no longer serviceable.
Confirm tube-wall thickness, metallurgy and repair locations.
Repair or replace only the non-serviceable defects identified during inspection.
Abrasive blast suitable areas to IGS surface-acceptance criteria.
Apply the specified alloy system to the approved thickness and boundaries.
Inspect thickness, document the completed scope and return the unit to service.
Final application boundaries and alloy selection are confirmed from outage inspection findings and actual substrate condition.
PC boiler protection
Low-NOx combustion, reducing conditions, high-temperature sulfidation and erosion can drive wall loss across waterwalls, slopes, burner zones and superheaters. IGS HVTS® creates a dense, corrosion-resistant barrier without a heat-affected zone or post-weld heat treatment, helping preserve serviceable tube metal and prevent further crack propagation where tube condition permits.
PC boiler case study
Robotic UT identified wastage across both sidewalls, the rear wall slope and burners, and the front wall slope and burners. IGS mobilized rapidly and protected the affected boiler tubing within the scheduled outage.

Some facilities manage PC boilers, gas turbines and HRSGs across the same site or fleet. IGS supports each asset with a focused solution designed around the actual degradation or fouling mechanism.
Mitigate fireside corrosion and erosion across waterwalls, slopes, burner zones and superheaters while preserving existing pressure parts.
Explore PC boiler protectionApply HVTS® superalloy cladding on susceptible compressor discharge and combustor-section surfaces to prevent oxide flakes from damaging downstream components.
Explore gas turbine protectionWhere suitable, use controlled, subsonic pressure waves online to remove deep ash deposits, reduce backpressure and recover heat-rate efficiency when fouling limits load, heat transfer or outage flexibility—without abrasive contact with pressure parts.
See the Lodi Energy Center projectPressureWave+™ proof
At the 282 MW Lodi Energy Center, IGS completed 1,584 PressureWave+™ events across four HRSG sections. The campaign removed heavy rust fouling and debris accumulations up to 25 inches while improving access for future cleaning scopes.
