High Velocity Thermal Spray (HVTS)


High Velocity Thermal Spray (HVTS)

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.

What is high velocity thermal spray?

High velocity thermal spray is Integrated Global Services’ (IGS’) proprietary technology to deposit high nobility metal alloys onto the substrate to achieve a corrosion-resistant barrier that offers greater protection than weld overlay while negating the need for heat treatment and avoiding heat-affected zones (HAZ).


High Velocity Thermal Spray (HVTS) vs Weld Overlay

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.

High Velocity Thermal Spray (HVTS) vs Organic Coatings

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.
