Flowserve Corp.has approved Hardide Coatings’ tungsten carbide-based coating for use on its McCANNA standard metal-seated valve applications. The use of Hardide has enabled Flowserve to offer the base metal in 316SS steel for use in severe service applications that require metal-to-metal seating, including abrasive and slurry applications. Flowserve will offer Hardide as a standard metal seated option for the McCANNA seal top entry ball valve on 1/2in to 4in RP/FP, ANSI 150-1500 and cryogenic to 800OF maximum temperature applications. These results follow two years of co-operation between the companies which included extensive engineering design and testing. Hardide is also working with Flowserve on the re-design and testing of two other product lines with results expected within the next three to six months.
