Turbine Shaft Repair Using ENECON Products

At a utility facility in the Midwestern U.S., a turbine shaft suffered severe cavitation damage—a common issue in high-velocity fluid systems where vapor bubbles form and collapse, eroding metal surfaces over time.

Repair Procedure Overview

  1. Surface Preparation - The damaged shaft was grit blasted to remove contaminants, corrosion, and prepare a clean, profiled surface for bonding. After blasting, the shaft was thoroughly cleaned to remove any residue or debris.
  2. Dimensional Rebuild with METALCLAD DurAlloy - DurAlloy, a high-performance polymer alloy, was used to rebuild the shaft diameter to its original specification. This material offers excellent adhesion, compressive strength, and machinability, making it ideal for restoring worn or damaged mechanical components.
  3. Protective Coating with FLEXICLAD DuraTough DL - After rebuilding, the entire shaft underwent brush blasting to prepare it for final coating. It was then coated with FLEXICLAD DuraTough DL, a flexible, abrasion- and cavitation-resistant polymer coating. This layer acts as a permanent barrier against future cavitation, erosion, and corrosion.

Benefits of the ENECON Dual-System Solution

  • Long-Term Protection: DuraTough’s flexibility and toughness significantly reduce the risk of future damage from cavitation.
  • Cost-Effective: Avoids expensive shaft replacement or prolonged downtime.
  • Durability: The combination of DurAlloy’s structural integrity and DuraTough’s protective properties ensures years of reliable performance under harsh operating conditions. Field Proven: Ensuring expert-level execution and product performance.

Summary

This is a textbook example of a composite repair strategy utilizing ENECON’s advanced materials:

  1. DurAlloy for structural rebuilding,
  2. DuraTough DL for protective surface engineering.

Together, they restore functionality and extend the operational life of high-value components such as turbine shafts, even in the most aggressive industrial environments.
