Stop Process Vessel Corrosion

Prevent Process Vessel Corrosion with HVTS

Refineries and Petrochemical Plants across the globe utilize HVTS, an IGS solution, to prolong the asset life of their high temperature and high pressure process equipment, including columns, towers, process vessels, separators and drums.


Process Vessel Asset Reliability | 5 Pillars of Success

At IGS, we work tirelessly to minimize risk and maximize value for our customers through all five critical aspects of our Engineered Surface Protection Solutions. You can count on IGS for Reliable Field Execution and Lasting Solution Performance.



We specialise in:

Whitepaper: Crude Distillation Unit Column Corrosion Protection

Field-applied HVTS alloy cladding offers a robust solution where other technologies fall short.

IGS delivers commercial or technological benefits by mitigating:

  • Pitting corrosion
  • Amine and caustic corrosion
  • Erosion
  • Stress corrosion cracking
  • Metal dusting
  • Free fatty acid corrosion

What is HVTS?

  • Robust engineered NiCrMoXX metallurgy upgrade cladding that mitigates corrosion and erosion
  • Applied turnkey in situ using a true high velocity thermal spray process
  • Adopted by top refineries and chemical plants globally as a gold standard for surface protection

Key Benefits of HVTS for Preventing Process Vessel Corrosion

No Risk of Application Failure 

HVTS does not experience failures that result from field welding or organic coating application by general contractors.

Total Asset Life Protection

HVTS offers lasting protection and does not require frequent reapplication. It will last for the duration of the asset life.

Peace of Mind & Technical Benefits

Each cladding is engineered for its intended environment. Inspections during normal operation are possible to verify integrity.

Commercial Benefits

HVTS delivers superior results at a fraction of the cost of vessel replacement or field welding.


I am a multiple repeat customer. I always get the best service and product and will continue to use HVTS and IGS.

WATCH: Unexpected Process Vessel Corrosion Addressed thanks to IGS Fast Response

When a client came to IGS to extend the life of a retirement-bound separator vessel, they hoped to gain a life extension of only 4 years. 10 years later the asset is still in operation and has been marked for permanent continuity, delivering significant ROI and saving the client:

  • $50m in cost of replacement asset
  • Cost of downtim
  • Supply chain emissions reduction
  • Fuel savings

WATCH: How did IGS achieve Long-Term Corrosion Protection for Critical HT H2S Process Vessels?

IGS executed a major corrosion protection project where high temperature H2S-containing process vessels where protected from corrosion for the long-term.


Asset Life Extension

Our claddings offer lasting surface protection where alternative technologies fall short. IGS’s consistent service is the reason why asset owners across the globe in the Oil, Gas, Petrochemical and Chemical industries, among others, trust IGS with their mission critical equipment.


Faster Turnarounds

We understand the need to reduce critical path and successfully complete emergent and site discovery work. Our solutions do not require heat treatment, have no cure times and reduce future maintenance requirements. IGS retains a permanent team of experienced project managers and technicians who take pride in their work. We collaborate with EPCs, Licensors, and other vendors on site for a smooth and stress-free turnaround.

Engineered Alloys

Our HVTS (High Velocity Thermal Spray) Alloy Cladding systems are specifically engineered for their intended environments. IGS can replicate your process conditions and test the suggested cladding for your project in our state-of-the-art Technology Center in Richmond, Virginia.
