Innovative solutions for renewable energy
Power generated by hydroelectricity is currently the most widely used form of renewable energy. From small beginnings in the late-19th century, hydroelectric power has grown in popularity throughout the world with some countries using hydropower to generate the majority of their electricity.
Protective coatings are vital to maintaining the functionality and operational reliability of various parts of the hydroelectric plant, including conduits, penstocks and gates. Our coatings are designed to withstand a wide variety of aggressive conditions, such as fast-flowing water, chemical pollution, abrasion and impact of small debris.
Durability by design
Hydroelectric plants have long economic lives, with some still in service after 50–100 years. However, plant owners have to overcome increases in construction, maintenance and production costs, all of which have a significant impact on productivity and profitability.
With unrivaled experience in this industry, PPG helps hydroelectric energy producers meet this challenge by providing the most efficient coating solutions to make plant and equipment last longer, work better, and achieve lower ongoing maintenance costs. We have specifically designed coating systems to protect critical power assets, including the dam, water intake/outflow, power generation and transmission.
A commitment to sustainable responsibility
The hydroelectric industry has established itself as a leading source of ‘green’ energy and is set to play a major role in transforming the global energy supply structure towards a truly sustainable energy future based on non-polluting and renewable technologies.
We also take our responsibility to sustainability very seriously and implement environmentally preferred practices in all areas of our organization. Our blueprint for the future is to design, build and operate our facilities in ways that prevent harm to public health and the environment, and also conserve energy, water and raw materials.
PPG HI-TEMP 1027™
PPG HI-TEMP 1027 coating prevents Corrosion Under Insulation (CUI) of carbon and stainless steel over an extreme temperature range from -185°C to 650°C (-300°F to 1,200°F).
High-temperature resistant coatings
High-temperature-resistant coatings are designed to withstand temperatures ranging from 150°C (300°F) to over 760°C (1,400°F) while providing protection against corrosion. For service under insulation, a single-component product like the PPG HI-TEMP 1027™ coating can be used for a wide range of operating temperatures and provides excellent protection against corrosion under insulation (CUI).
SIGMASHIELD™ 880: Changshan Thermoelectric Plant
The SIGMASHIELD 880 coating’s superior water immersion resistance and abrasion resistance makes it the ideal product to protect both the interior and exterior of the large Changshan water circulating pipes.
