Q1: What is Monel 400 made of?
A1: Monel 400 is a nickel-copper alloy containing about 67% nickel and 23% copper, with small amounts of iron and manganese. It is known for its excellent resistance to seawater and steam at high temperatures, as well as to salt and caustic solutions.
Q2: What are the main applications of Monel 400 tubes and pipes?
A2: Monel 400 tubes and pipes are widely used in marine engineering, chemical processing, oil and gas industries, heat exchangers, and piping systems where strong resistance to corrosion and high strength are required.
Q3: How does Monel 400 perform compared to stainless steel?
A3: While stainless steel offers good general corrosion resistance, Monel 400 outperforms it in highly corrosive environments such as seawater, acidic and alkaline media. It also retains mechanical strength at both subzero and elevated temperatures, making it more suitable for demanding applications.
Q4: What forms and sizes are available for Monel 400 tubes and pipes?
A4: Monel 400 tubes and pipes are available in seamless and welded forms. They can be supplied in a variety of sizes, thicknesses, and lengths according to customer requirements and international standards such as ASTM B165 and ASTM B725.
Q5: How is the price of Monel 400 tubes and pipes determined?
A5: The price depends on several factors, including the size and wall thickness of the tube/pipe, manufacturing method (seamless or welded), surface finish, order quantity, and market fluctuations in nickel and copper raw material costs.
