Turbine Francis 𝘎𝘌𝘕𝘐𝘚𝘚𝘐𝘈𝘛

Installing and modifying stainless steel shielding

During a turbine maintenance, when the Francis wheel was dismantled by ALSTOM HYDRO, the customer noticed an extremely large cavitation with in some places a total piercing of the shield.

To ensure the optimum restart of the installation within the planned time frame, ALSTOM HYDRO contacted TACQUET INDUSTRIES in order to carry out a feasibility study and complete the work within the given time frame.
