Process Vessel Reliability in Sour Service
200+ Vessels and 7,000+ m² Protected With HVTS®
IGS HVTS® alloy cladding helps Oil & Gas operators protect critical process vessels from sour service corrosion, steam-out damage, and recurring repair scope.
See how HVTS® supported a long-term reliability program at Tengizchevroil,
protecting more than 7,000 m² across process vessels and sour service equipment.

Why Operators Use HVTS® for Sour Service Vessels
- Dense CRA alloy protection
- No fusion welding = no HAZ, no PWHT
- Resistant to steam-out damage
- Suitable for field application during turnaround
- Supports visual and NDT inspection
- Designed for long-term reliability planning
Protect Critical Vessels in Aggressive Service
Process vessels in sour service can be exposed to H₂S, CO₂, chlorides, amines, sour water, acid gas breakout, and high-temperature steam-out cycles.
HVTS® applies a dense corrosion-resistant alloy barrier to the internal vessel surface, helping protect the pressure boundary and reduce future repair scope.
Used Across Critical Process Equipment
IGS HVTS® is used to protect corrosion-prone assets including:
- Amine contactors and regenerators
- Sour water strippers
- Desalters
- Separators
- Flare knock-out drums
- Quench columns
- Cooling towers
- Process columns and vessels
“HVTS gave us a durable alloy barrier for critical sour service vessels, helping reduce recurring repair scope and support long-term reliability during turnaround planning.”
