In the steel and metal processing industry, critical equipment such as heat exchangers is essential for maintaining efficient operations. However, like other machinery in harsh environments, heat exchangers require regular heat exchanger maintenance to combat issues like abrasion, erosion, and corrosion. Belzona offers metal repair composites and durable protective coatings designed to reduce downtime and extend the life of your equipment.
In a recent heat exchanger maintenance project in Brazil, Belzona was tasked with addressing a significant problem: galvanic corrosion on the tube face of a heat exchanger, which resulted from the contact between dissimilar metals. The heat exchanger is crucial for transferring heat in the steel manufacturing process, making its optimal functionality essential for production efficiency.
Galvanic corrosion occurs when two dissimilar metals come into contact in the presence of an electrolyte, leading to accelerated corrosion on one of the metals. In this case, the tube face of the heat exchanger made from carbon steel was suffering from this issue, jeopardizing its integrity and performance.
To address the corrosion issue, the heat exchanger maintenance process was carried out in situ, according to Belzona’s system leaflet HEX-01, a step-by-step guide on how to apply a Belzona product to a heat exchanger. The key steps included:
The Customer expressed satisfaction with the heat exchanger maintenance, as the in-situ application eliminated the need to disassemble the heat exchanger, thus saving time and labor costs. Belzona’s products not only resolved the corrosion issue but also enhanced the efficiency of the heat exchanger, ensuring it continues to perform optimally in the steel manufacturing process.
Regular heat exchanger maintenance is critical for the steel and metal processing industry to ensure equipment longevity and operational efficiency. Belzona’s innovative in-situ solutions offer proven protection against common issues like galvanic corrosion, helping companies maintain high levels of productivity.
