Problem Tube sheets and water boxes are subject to severe corrosion due to the construction with dissimilar metals and corrosive water. The pitting corrosion around the tubes will rapidly create leakages while corrosion of baffle plates and water boxes results in early replacements and severe capacity loss. Simply applying a coating will not prevent this due to the complexity of the construction. A special procedure must be followed to ensure the coating system will protect the valuable equipment for many years.

Why use Blygold Tube sheet coating?   • Corrosion causes leakages and capacity loss • Corrosion results in early replacement or retubing

Solution   Blygold protects tube sheets and water boxes from leakages and prevents early replacements. The dissimilar metals of the tube and sheet are sealed from the corrosive environment by means of a smooth and resistant coating. The special pretreatment ensures perfect adhesion, smooth surfaces, prevents pressure drop and guarantees an extra protection at critical areas. The dust free blasting and VOC coating makes the treatment suitable for both factory and site application. Reconstruction of severely corroded baffle plates prevents capacity loss.
