Project Description

Integrated Global Services (IGS) applied HVTS Cladding (IGS 5470) and Top Coat (IGS 6310) to address internal shell corrosion in a quench tower at a facility in Singapore. The project included nozzle sleeving and utilized cutting-edge HVTS technology for enhanced erosion resistance.


The detection of corrosion within the internal shell area of the quench tower has emerged as a pivotal concern, signifying a substantial challenge to the structural integrity of the facility. This issue demands a meticulous and comprehensive mitigation strategy to not only rectify the existing corrosion but also to fortify the affected components. The imperative lies in preserving the long-term operational resilience of the quench tower, ensuring that it adheres to stringent safety and performance standards. Given the critical role of the quench tower in industrial processes, a robust and carefully orchestrated mitigation effort becomes essential, aligning with best practices and industry standards to guarantee the sustained functionality of the facility.



In response to the identified corrosion within the internal shell area of the quench tower, IGS implemented a sophisticated and strategic solution through the HVTS process. This advanced methodology involved the application of claddings characterized by heightened density and reduced permeability, ensuring a superior protective barrier against corrosion. The meticulous approach extended to the incorporation of nozzle sleeving, featuring precision-engineered Inconel 625 inserts to enhance corrosion resistance in critical areas.

Recognizing the significance of substrate preparation, the original organic coating was methodically removed, setting the stage for the application of HVTS cladding to the extent of 318 square feet. This comprehensive removal and reapplication process aimed not only to rectify existing corrosion but also to fortify the substrate against future deterioration. By adopting this multi-faceted solution, IGS showcased a commitment to precision engineering, leveraging cutting-edge technology to achieve optimal results and extend the operational life of the quench tower while adhering to the highest industry standards.
