Monel 400 is copper nickel alloy,has good corrosion resistance. In
salty water or seawater has excellent resistance to pitting
corrosion, stress corrosion ability. Especially hydrofluoric acid
resistance and resistance to the hydrochloric acid. Widely used in
the chemical, oil, Marine industry.
It is widely used on many aspects,like valve and pump parts,
electronic components, chemical processing equipment, gasoline and
freshwater tanks, petroleum processing equipment, propeller shafts,
marine fixtures and fasteners,boiler feedwater heaters and other
heat exchangers.

Monel tubes are widely used in various fields due to their
excellent corrosion resistance and high temperature strength. The
application areas of Monel tubes include but are not limited to the
following:
1. Chemical industry: Monel tubes can be used for the production
and transportation of strong acid and alkali media such as
chlorides, nitric acid, sulfuric acid, as well as seawater
treatment, petrochemicals, and other fields.
2. Aerospace industry: Due to the excellent high temperature
performance and corrosion resistance of Monel alloy, it is widely
used in the manufacture of high temperature components such as
engines and turbines.
3. Marine engineering: Monel tubes have excellent corrosion
resistance to seawater, so they are widely used in seawater
desalination, offshore oil exploitation, and shipbuilding.
4. Food processing industry: Monel tubes have good corrosion
resistance and non-toxicity, so they are widely used in production
equipment and conveying pipelines in the food processing industry.
In summary, Monel tubes have wide applications in many fields due
to their excellent corrosion resistance, high temperature strength,
and non-toxicity.
