Unique Polymer Solutions

What are the main maintenance challenges in hydroelectric power plants?

Hydropower facilities play a critical role in global clean energy generation, but they are constantly exposed to severe mechanical, hydraulic, and environmental stresses. These include:

Cavitation damage on turbines, guide vanes, and wicket gates
Erosion and abrasion from high-velocity water flow, silt, and debris
Corrosion of penstocks, steel structures, and valves
Moisture ingress and fatigue in damp or submerged systems
Concrete degradation in spillways, canals, and control structures

If not addressed effectively, these issues can result in equipment failure, reduced energy output, increased safety risks, and unplanned downtime.

How can protective coatings improve the durability of hydroelectric infrastructure?

At UNIQUE POLYMER SYSTEMS (UPS), we offer engineered protective coatings specifically formulated for submerged, high-flow, and chemically aggressive environments.

Our Coating Solutions Offer:

Cavitation and erosion resistance – for turbine runners, impellers, and draft tubes
Corrosion-resistant epoxy linings – for penstocks, valves, spillways, and water channels
Barrier coatings for steelwork – gates, screens, railings, ladders, access platforms
Concrete protection systems – for tanks, foundations, surge chambers, and canals
Chemical-resistant coatings – for hydraulic fluid bunds, oil containment zones, and chemical exposure areas

These solvent-free, fast-curing coatings are easy to apply and ensure long-term protection with minimal maintenance disruption.

What repair solutions are available for damaged or aging hydroelectric equipment?

UPS also provides composite repair systems designed to restore damaged infrastructure quickly and cost-effectively — without equipment removal or hot work.

Composite Repair Applications Include:

Metal repair compounds – rebuild turbine housings, guide vanes, pump internals, and valve components
Structural reinforcement wraps – reinforce corroded pipework, brackets, and steel support elements
Concrete repair systems – restore eroded spillways, surge tanks, channels, and foundations
Leak sealing and pipe wrapping kits – maintain pressure integrity and prevent water ingress

These systems extend asset life, minimise downtime, and are ideal for in-situ application during routine maintenance windows.

Where are UPS coatings and repairs used in hydroelectric power plants?

Our systems are applied across all major areas of hydroelectric infrastructure:

Turbine and generator housing protection
Penstock internal coating and sealing
Gate and valve repair and protection
Concrete restoration in spillways and surge chambers
Pipe repair in pressurised and submerged systems
Corrosion prevention for ladders, platforms, gates, and railings

Whether for run-of-river, reservoir-based, or pumped storage plants, UPS solutions deliver durable, cost-effective protection.
