Products Description
Niobium is a soft and ductile metal, which makes it a good material for tubes, pipes, and even capillary tubes. The purity of the niobium can be up to 99.95%. Various dimensions of the niobium tubing are available. Please contact us for more details.
The application of Niobium pipes
1. Aerospace: These are niobium pipes used in aerospace applications where high strength with low weight and resistance to high temperatures can be used for specific components.
2. Nuclear: Niobium pipes also exhibit good corrosion resistance in liquid metals like sodium and potassium. Therefore, it is suitable for applications in nuclear reactors, especially in those belonging to the class of sodium-cooled fast reactors.
3. Chemical Processing: Niobium pipes are resistant against corrosion in a wide variety of chemicals; hence, these have been found useful in the processing of aggressive fluids containing acids and bases.
4. Petroleum and Gas: The resistance to corrosion and resistive qualities of high temperature make the material fit for use at higher temperatures and in uses like downhole applications in the oil and gas industry.
5. Electronics: Nb pipes are utilized in the electronics industry for superconducting purposes as it has a ≤ of higher temperature than any other material.
Characteristics of niobium pipes
High Melting Point: Niobium pipe has a melting point of 2468°C or 4454°F hence its use in such high-temperature applications.
Corrosion Resistance: The resistance of the niobium pipe to corrosion is outstanding in a wide range of hostile environments, from high chloride concentration to immersion in acid or alkali.
High-Temperature Strength: Nb has mechanical properties at high temperatures that make it an excellent candidate for application in those high temperatures where other metals may soften or degrade.
Mechanical Properties Formability: The workability of niobium includes the production of various forms, such as pipes, without affecting mechanical properties.
Thermal conductivity: The thermal conductivity of a niobium pipe is average, hence it could be used where dissipating heat is involved.
