Monel alloy steel pipe, also known as nickel alloy, is an alloy based on metallic nickel [1] and adding other elements such as copper, iron, and manganese. Monel alloy has good corrosion resistance and is silvery white, suitable for edge wire material.
The structure of Monel alloy is a high-strength single-phase solid solution and single-phase austenite structure. It is a corrosion-resistant alloy with the largest amount, the widest application and excellent comprehensive performance. This alloy has excellent corrosion resistance in hydrofluoric acid and fluorine gas medium, and also has excellent corrosion resistance to hot concentrated lye. At the same time, it is also resistant to corrosion by neutral solutions, water, sea water, atmosphere, organic compounds, etc. An important feature of this alloy is that it generally does not produce stress corrosion cracks and has good cutting performance. The alloy is mainly used in valve stems, pump shafts and impellers, conveyor scrapers, oil well drilling rings, elastic parts, valve pads, etc.

Application of Monel alloy steel pipe

Used in the manufacture of heaters, heat exchangers, evaporators, stills, distillation towers, condensers for fatty acid treatment, equipment for rosin booth acid treatment, chemical pumps, etc.
Because the alloy also has high strength and good oxidation resistance at high temperatures, it can also be used in the heat treatment industry to manufacture various structural parts.
In the nuclear power industry, this alloy has good corrosion resistance to high temperature and high pressure water, so it is also an important structural material for light water reactor nuclear power plants. The products include plates, rods, wires, strips, and pipes.
