HYDROELECTRIC_STAY_RING_REPAIRS

Hydroelectric systems produce 20% of the world’s electricity, making them an integral part of the energy-producing industries. As both the age and reliance on these systems continues to increase, the integrity of the hydropower generating facilities will be called into question.

Whilst many OEMs would concentrate on ‘common repairs’ including pumps, spherical and butterfly valve and cavitation repairs, the often-overlooked importance of stay ring and stay vane repairs are just as important.

Stay ring repairs

Cracks or fractures to the stay ring should be a priority for repair.

Repairs to the stay ring take away the possibility of system failure or internal damage, and can have the potential to increase efficiency.

But finding portable machinery to accurately resolve your issues can be difficult due to the sheer size of the stay ring and the accuracy required to make the repair.
