Unique Application of an Epoxy Repair Gel to Eliminate Draft Tube Surface Wear and Cavitation, potentially Improving Turbine Power Generation Efficiency

Product Number: 41216-976-SG

Author: Norm Klapper

Publication Date: 2016

$20.00

A unique project was completed in Mid-2014 at the Powerhouse #3, Turbine Unit #23 refurbishment, Grand Coulee Dam, located in Washington State. The project scope includes a complete overhaul of the turbine bearings, windings, and critical components. As part of the overall scope, the contractor was charged with the task of coating the entire draft tube surface with an epoxy gel. The Bureau of Reclamation, based in Denver, Colorado, had conducted a site survey which indicated severe wear lines, which result in cavitation and the accompanying backpressure on the exiting water outflow to the Columbia River.
