Hydropower

Our specific anti-corrosion solutions repair and protect these parts, significantly increasing their efficient work life. This process ensures long-term durability, minimizing the need for frequent maintenance and reducing operational downtime.

Our specific applications make the reconstruction of complex parts possible, ensuring precise restoration and extending the lifespan of vital components. By utilizing advanced techniques, we enhance the durability and performance of these parts, reducing the need for costly replacements and minimizing downtime in demanding industrial environments.

Constant use leads to structural damage in large turbine components. Our specific applications make it possible to reuse and restore these shafts in-situ, ensuring efficient repair directly on-site. This process significantly decreases downtime, allowing for quicker resumption of operations while extending the lifespan of the turbine. By minimizing shutdown time and reducing the need for full replacements, we enhance both performance and cost efficiency in demanding industrial environments.

Abrasion in turbine casings is mainly caused by the constant flow of sediment-laden water through the turbine system. This extreme wear can lead to significant damage over time. However, Castolin Eutectic offers specialized applications to effectively restore and protect turbine casings from further abrasion. Our solutions not only repair the worn surfaces, but also create a durable protective barrier, extending the life of the turbine and reducing costly maintenance. By using our advanced technology, you can ensure that your turbine system remains efficient, reliable, and resistant to abrasive damage for the long term.

Valve spindles are critical components that facilitate the opening and closing of valves, but are subject to constant wear and tear. Castolin Eutectic solutions enable the reuse of these important pieces of equipment, ensuring that they are restored to optimum functionality. Our advanced repair techniques not only extend the lifetime of valve spindles, but also minimize the need for costly replacements, reducing downtime and increasing overall operational efficiency. With our solutions, you can maximize the performance and durability of your valve spindles, making your systems more reliable and cost-effective in the long run.

Inefficiencies caused by cavitation wear are one of the most significant challenges in the hydropower industry. This type of wear can drastically reduce the performance and lifetime of critical components. Castolin Eutectic's specialist applications using CaviTec solutions provide an efficient and cost-effective method of tackling these wear issues. Our solutions not only restore damaged surfaces, but also strengthen them against future cavitation damage. By applying our advanced technology, you can increase the durability and efficiency of your hydropower systems, minimize costly downtime and maintenance, and extend the life of your critical equipment.

This range includes Uniquely Engineered Electrodes (SMA) and Wires (GMA) specifically designed to resist severe cavitation-erosion damage. CaviTec, an austenitic-type alloy with controlled amounts of chromium, cobalt, silicon, and manganese, offers enhanced properties that significantly improve strain-hardening and shock-dampening capabilities. The finely balanced composition of these elements results in improved cavitation-erosion resistance, making CaviTec last up to six times longer than traditional stainless steel overlays. This high-strain, work-hardening austenitic stainless steel provides maximum protection for critical areas that require frequent or major repairs. With all-position weldability, CaviTec allows for easy controlled overlapping and profiling, ensuring seamless application.

CaviTec's austenitic γ-phase structure transforms under cyclical stress into an α-martensitic phase, resulting in fine deformation twinning, which further boosts its durability. Its proven performance makes it an ideal solution for the most demanding industrial environments, reducing downtime and maintenance costs while maximizing equipment lifespan.
