Different linings have been used to reduce cavitation damage on the downstream side of the butterfly valves, with minimal success. Laboratory testing identified two commercial polyurethane elastomers that may provide better cavitation resistance than prior linings used in draft tubes for cavitation resistance. The two lining materials were selected for field trials on a Flatiron Powerplant Unit 2 butterfly valve as a cavitation repair material for filling the entire cavitation pit, i.e., without stainless steel weld repair. The butterfly valve has a moderate cavitation environment with an approximate pressure drop of 500 pounds per square inch.\", \"distribution\": [{\"@type\": \"dcat:Distribution\", \"accessURL\": \"https://data.usbr.gov/catalog/8001/item/128575\", \"description\": \"Landing page for \\\"S&T Project 20024 Flatiron Powerplant Interim Report: Flatiron Powerplant Unit 2 Butterfly Valve Cavitation Resistant Coating Field Trial\\\"\", \"mediaType\": \"text/html\", \"title\": \"RISE Item Details Page URL for \\\"S&T Project 20024 Flatiron Powerplant Interim Report: Flatiron Powerplant Unit 2 Butterfly Valve Cavitation Resistant Coating Field Trial\\\"\"}, {\"@type\": \"dcat:Distribution\", \"description\": \"\\\"S&T Project 20024 Flatiron Powerplant Interim Report: Flatiron Powerplant Unit 2 Butterfly Valve Cavitation Resistant Coating Field Trial\\\" as a PDF file\", \"downloadURL\": \"https://data.usbr.gov/rise/content-rise-public/rise/catalog-item/binary/8540-2023-34 Flatiron Cavitation Field Trial 4-24_508_Signed_AS_GW_MH_BM.pdf\", \"mediaType\": \"application/pdf\", \"title\": \"PDF File for \\\"S&T Project 20024 Flatiron Powerplant Interim Report: Flatiron Powerplant Unit 2 Butterfly Valve Cavitation Resistant Coating Field Trial\\\"\"}], \"identifier\": \"https://datainventory.usbr.gov/rise/item/128575\", \"keyword\": [\"Cavitation\", \"Ceramic-filled Epoxy\", \"Coatings\", \"Cold Spray\", \"Polyurethane Elastomer\"], \"landingPage\": \"https://data.usbr.gov/catalog/8001/item/128575\", \"modified\": \"2024-01-04T19:59:18Z\", \"publisher\": {\"@type\": \"org:Organization\", \"name\": \"Bureau of Reclamation\"}, \"spatial\": \"{\\\"type\\\":\\\"Polygon\\\",\\\"coordinates\\\":[[[-124.508,48.197],[-124.304,40.096],[-117.02,32.608],[-103.405,29.136],[-93.466,30.77],[-94.692,38.939],[-97.279,48.946],[-122.67,48.946],[-124.508,48.197]]]}\", \"title\": \"S&T Project 20024 Flatiron Powerplant Interim Report: Flatiron Powerplant Unit 2 Butterfly Valve Cavitation Resistant Coating Field Trial\"}","source_transform":null,"status":"error"}
