IGS High Velocity Thermal Spray (HVTS) is a robust solution that extends the life of existing equipment. IGS’s HVTS cladding upgrades existing metallurgy to higher alloys. HVTS acts as a corrosion/erosion barrier in mission-critical equipment, including boilers, process vessels, towers and columns.
IGS alloys meet or exceed the performance characteristics of their wrought alloy analogs. We modify high-grade alloys including Inconel® 622, Inconel® 625, Inconel® 825 and Hastelloy® C276, to provide optimal material characteristics for your specific equipment and environment.
High Velocity Thermal Spray is a preferred alternative to weld metal overlay (WMO) or organics since the IGS technology is more flexible and cost-effective.
The HVTS application is significantly faster than weld metal overlay. High Velocity Thermal Spray solution provides excellent up-front cost reduction and long-term ROI due to material and labor savings. Savings as high as 50% are frequently achieved.
Furthermore, HVTS doesn’t create a Heat Affected Zone (HAZ) and therefore will require no post weld heat treating (PWHT) saving more time and putting your equipment under less stress.
IGS HVTS has one major advantage against organic coatings. HVTS does not require any curing time or bake out. HVTS is also insensitive to atmospheric temperature and humidity. As a result, the HVTS application can reduce critical path turnaround time by up to ten days, bringing your unit back into operation that much sooner.
HVTS does not have the low service temperature limitations that organic coatings do. Metal coatings can withstand much harsher environments and are resistant to impact damage that may commonly occur during a turnaround.
IGS is the industry leader in on-site corrosion protection for mission critical equipment. We safely operate on site during turnarounds in partnership with our customers and their other vendors.
We have performed over 4,000 site projects and installed millions of square feet of reliable surface protection across the globe. Our customers avoid costly replacement without sacrificing long-term reliability of their boilers and vessels.
