福斯推出镍铁硬质合金
球阀
美国福斯最近将哈迪特镍铁制成的硬质合金，涂在标准金属阀座配件的表面。
表层涂碳可以让福斯生产316ss型号的线材金属，专用于几种服务设备所需的金属对接，包括磨料和水泥浆的应用。
福斯驻美国商务发展部经理DanWilson认为：改进前的调节阀产品在泥浆中运行29000次之后，就自动失效了，镍铁合金球体和阀座在泥浆中运行70000次后，仍就能够继续保持运行。
Flowserve offers tungsten carbide coating for ball valves
Flowserve uses Hardide Coatings’ tungsten carbide-based coating on
its McCanna standard metal seated valve applications.
Tungsten coatings allows Flowserve to offer the base metal in 316SS steel
for use in severe service applications requiring metal to metal seating,
including abrasive and slurry applications.
“Hardide coated balls and seats were still operational after more
than 70,000 cycles in slurry where Stellite failed in 29,000 cycles,”
said Dan Wilson, Hardide’s US-based business development manager.
