Stacks and chimneys are exposed to combustion gases, moisture, and acidic compounds. The top area of the stack can experience severe corrosion and failure, especially around flanged joints. The unlined carbon steel stack will require frequent and costly part replacement.
Increased sulfur in fuel and alternative fuel sources have all contributed to the corrosion problems. Following 4 or 5 years of uncontrolled corrosion, a stack can face wall thickness loss, causing the structure to become unsafe.
Stack corrosion can be effectively mitigated with IGS HVTS.
Developed for safe on-site application IGS HVTS can be used to permanently stop metal wastage, preventing the need to cut and replace the metal parts or continuously reapply low-performance coatings.
Global Metals & Mining smelters benefit from this innovative metal wastage solution in their pyrometallurgical furnaces, waste heat boilers, baghouses, off-gas ducting, ESPs, and stacks.
IGS has protected mission-critical process equipment against corrosion and wear damage for over 20 years. IGS has successfully provided over 400,000 m2 of surface protection across more than 3,000 projects in over 30 countries on 6 continents.
Fully trained and certified in-house personnel provide turnkey installations, operating under robust HSE and QMS programs, providing our customers with the safest and most reliable surface protection service available. Our customers attest that our safety-first culture noticeably sets IGS apart from most industrial contractors.
