Monel belongs to a group of alloys, which consists of nickel and copper. Apart from this Monel also consists of manganese, carbon, iron, and silicon in small amounts. Monel Pipes are resistant to a range of corroding elements. Pipes made from Monel can also resist corrosion from rapidly running sea-water.
Monel is costly when compared to copper and nickel, thus finding use in limited applications. Monel is used in aircraft construction, and frames of rockets, as it retains strength at high temperatures. Monel pipes also offer good resistance against hydrofluoric acid up to boiling point in all concentrations. These pipes also offer some resistance to sulphuric and hydrochloric acids in reducing conditions. Pipes made using Monel find applications in other applications such as pump shafts, piping systems, seawater valves, trolling wires and strainer baskets. Monel also serves applications in many chemical industries as it offers resistance to corrosion from acids and oxygen. Types of Monel include Monel 401, Monel 404, Monel 405, Monel K-500 and Monel R-500.
