UNS N05500 Monel Pipe Description

Monel K500 seamless tubing is a nickel-copper alloy, stronger than pure nickel, and is widely used in many fields. Monel K500 seamless pipe can be used to make hangers and tools, as well as components for wells, pressure heads, downhole tubing and heat exchange equipment. Pumps and propeller shafts, electrical and electronic parts, gas tanks and crude oil stills. It can also be used to manufacture offshore drilling platforms.
