Anti-corrosion treatment interventions on the TV2 steam condenser
In the industrial sector, maintenance and protection of facilities are essential to ensure efficiency and safety. The anti-corrosion treatment carried out on the TV2 steam condenser is an example of how GMA, with its engineering expertise, can deal with critical corrosion-related problems. In this article, we will explore in detail the phases of this project, the technologies used and the importance of timely and targeted intervention.
Introduction to the Project
From 12 November to 23 December 2024, GMA carried out anti-corrosion treatment on the steam condenser of the TV2 group at a power station, with the aim of ensuring the longevity and efficiency of the installation. The project involved the application of a specific epoxy coating, Phencote HR60TL, to various components of the condenser, including pipes, tube plates and water boxes.
The importance of maintenance
Corrosion is one of the main enemies of industrial installations, and without adequate protection, copper-nickel alloy pipes can suffer significant damage, such as differential aeration corrosion and corrosion under deposit. These phenomena can lead to costly plant shutdowns and compromise safety.
Project phases
The phases of the intervention were carefully planned to ensure maximum efficiency and safety. A detailed description of the activities carried out follows.
Surface preparation
Surface preparation is crucial to ensure coating adhesion. Before applying the coating, thorough sanding was carried out to remove any oxidation and contamination. This phase required:
- Removal of the water tank doors to access the surfaces to be treated.
- Use of probes of different lengths to ensure thorough cleaning.
The sandblasting results were evaluated using Testex Coarse in accordance with ISO 8503/5, with roughness values between 30 and 40 microns, thus ensuring adequate preparation.
Application of the coating
The Phencote HR60TL epoxy coating was carefully applied to completely cover:
- Internal piping
- Tubular plates
- Water tanks
This phase was monitored by NACE and INAC certified inspectors, ensuring that quality standards were met. The choice of this coating was not random: Phencote HR60TL offers effective protection against corrosion while reducing the degree of accumulated dirt thanks to a less rough surface.
Monitoring and control
Throughout all phases, an internal inspection team was present, assisted by GMA specialists. Constant monitoring allowed any problems to be identified in real time, minimising risks and ensuring that the intervention was completed within the planned deadlines.
Results and benefits
The anti-corrosion treatment intervention has brought several tangible benefits:
- Reduction in plant downtime: thanks to the protection provided by the coating, a significant reduction in corrosion risks is expected, thereby reducing plant downtime for maintenance.
- Increased installation longevity: anti-corrosion treatment interventions can extend the service life of equipment, enabling a faster return on investment.
- Improved safety: corrosion protection helps to ensure a safer working environment by reducing the risk of accidents related to structural failures.
Conclusion: anti-corrosion treatment is essential
In an industry where every hour of downtime can translate into significant costs, anti-corrosion treatment interventions such as the one carried out on the TV2 condenser are essential.
