Pressure Vessel Corrosion During TAR?
Over $10M Saved and 50%+ Schedule Savings During TAR
IGS HVTS® alloy cladding helps refineries and process plants reduce pressure vessel repair complexity, protect critical equipment, and support a faster return to service.
See how a multinational Oil & Gas company reduced cost and execution time
across three process vessels during a scheduled turnaround.
Commercial Impact Across Three Process Vessels
When corrosion is identified in critical vessels, repair decisions can have a major impact on turnaround cost, schedule, and execution risk.
In this project, HVTS® was selected to protect three process vessels during TAR, helping reduce repair duration and total cost while avoiding additional welding-related complexity.
| Process vessel | Traditional repair option | HVTS® |
|---|---|---|
| HCF Stripper | $256K / 12 days | $137K / 7 days |
| Tail Gas Quench Column | $730K / 27 days | $321K / 10 days |
| EKT Quench Tower | $10M / 28 days | $1.2M / 11 days |
Why HVTS® for Pressure Vessels?
When corrosion is discovered in critical process vessels, welding or replacement can add days or weeks to turnaround scope.
- No heat-affected zone, no PWHT
- Faster TAR execution
- Dense CRA alloy protection
- Designed for sour, acidic, chloride, amine, and caustic service
- Prevent future repair and replacement
- Long-term vessel integrity support
Protect Critical Vessels Without Added Repair Complexity
Pressure vessels can be exposed to acids, chlorides, amines, H₂S, CO₂, sour water, thermal cycling, and other corrosion mechanisms that threaten asset integrity.
HVTS® applies a dense corrosion-resistant alloy barrier to the internal vessel surface, helping protect the pressure boundary while reducing the schedule and cost impact often associated with major vessel repairs.
Used Across High-Risk Process Equipment
IGS HVTS® is used to protect corrosion-prone assets including:
- HCF towers
- Tail gas and quench columns
- Amine contactors and regenerators
- Sour water strippers
- Desalters
- Separators
- Flare knock-out drums
- Debutanizers
- Process columns and vessels
“HVTS gave us a faster, lower-risk repair route for critical process vessels during TAR, helping reduce execution time, cost, and repair complexity.”
