Monel pipes are a superalloy composed of nickel and copper and are a popular choice for chemical plants, oil refineries, petrochemical facilities and wastewater treatment plants because of their durability. They are also used in aircraft construction and rocket frames, as they retain strength at high temperatures. In small amounts, Monel also consists of manganese, carbon, iron, and silicon. These pipes were invented by the American engineer Robert Crooks Stanley in 1901, who patented it and named it after their company president, Ambrose Monel. Its corrosion resistance properties make monel ideal for chemical installations that withstand hostile humidity, temperature and abrasive conditions and resist corrosion from rapidly running seawater. Monel pipes are also affordable compared to stainless steel pipes – monel pipe price is relatively economical for its abilities, but compared to copper and nickel, it is expensive.
Monel pipes also offer good resistance against hydrofluoric acid up to the boiling point in all concentrations. These pipes also resist 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 400, Monel 401, Monel 404, Monel 405, Monel K-500 and Monel R-500.
Monel pipes offer many advantages in terms of properties and applications compared to traditional piping materials. In addition to these uses, monel pipes also have excellent mechanical fatigue strength and electrical conductivity. This allows monel to be used as an alternative material choice in multiple cracking loads components like bolts, tools, springs, and fasteners.
