Brock Services is a maintenance contractor for the Tri-State Generation & Transmission power plant in Craig, CO. Brock provides scaffolding, insulation and coatings services for the power plant.
Tri-State often conducts plant tours through their station for clients, partners and the public, where the main attraction is the main turbine deck. In an effort to provide insight into the equipment internals used in the generation of electrical power, Tri-State decided to display a Steam Turbine Rotor in proximity with the steam turbines, providing a visual of the unseen.
Tri-State asked Brock to prepare the surface of a spare steam turbine rotor and coat it for beatification so it could be exhibited on the parade route.
A containment was constructed at a location onsite away from the Turbine Building to perform the preparation and coating work. The containment was to assure environmental conditions were suitable for the coating project. The rotor was abrasive blasted with Australian garnet from GMA, then primed with PPG Amerlock epoxy mastic. Safety orange and safety red were applied to the HP blades to differentiate the low and high pressure functions of the rotor. The color scheme was recommended by BSLLC supervision and accepted by Tri-State.
Once completed, Tri-State placed the rotor on the main turbine deck in the center of all three units. The turbine deck is, as mentioned, the main attraction for plant tours of the plant. Tri-State has expressed great appreciation of the quality and aesthetics of the finished product.
